It's AumSum Time. Why is Pluto no longer a planet? Because I'm no longer being silly. Ya ya.
Now listen. Pluto was discovered by Clyde Tombaugh in 1930. It is no longer considered a planet because in 2006.
Astronomers gave the IAU a new definition of the word planet. According to the new definition, a planet is a celestial body. Which is in an orbit around the sun.
Has a spherical shape. And it has cleared the area around its orbit. What does that mean? Basically, it means that it is using its gravity.
A planet should have cleared asteroids and dwarf planets out of its way. So his neighborhood was cleared. Now Pluto is in orbit around the sun and is spherical in shape.
But since Pluto's neighborhood has many other objects. And he didn't clean his neighborhood. He's no longer called a planet.
Why do dead whales explode? Because there are thousands of fireworks in their bodies. Stop bluffing. If a dead whale is accidentally washed up on a beach.
It starts to decompose, since it is not eaten by sharks or other fish. During decomposition. Various gases such as methane and carbon dioxide are produced in its body.
But because there is a thick layer of fat under the skin of whales, the gases cannot escape whale's body, causing it to puff up . Now such gases are also produced in other animals after their death. But because a whale's body is large, it produces more gases.
This increases the pressure in his body. Finally because of the increased pressure. The accumulated gases, tissues, meat, etc. are forced to escape through weak points.
This creates an explosion. It is therefore always recommended not to stand or sit on a dead whale. As this can lead to increased pressure at weak points.
This leads to an explosion. What causes tides? Tides are the periodic rise and fall of the sea level in a given location. When the sea level reaches its greatest height.
It is known as a high tide and when the sea level at its lowest elevation. It is known as low tide. Tid These are mainly caused by the gravitational pull of the moon.
But how? A part of the earth that faces the moon experiences a stronger gravitational pull. Towards the moon compared to the center of the earth. The part facing the moon becomes from the center.
It creates a bulge and thus increases the sea level and causes a flood. Now the center of the earth experiences a stronger gravitational force. Towards the moon than the part away from the moon.
Therefore, this part is pulled away from the center . This also leads to high tide on the opposite side. Also.
The places between the two high tides. Where the sea level drops, you experience low tide. Why do snakes shed? Wait.
I will explain. When a snake grows. Their outer layer of skin, called the epidermis, it does not grow or grow with it, so the snake sheds its epidermis on a regular basis to allow its body to continue to grow, and shedding also helps remove any parasites that have struck the epidermis.
So the snake? Buy a new skin? No, listen first. Before shedding, the snake grows a new epidermis under the old one. And secretes a fluid between the old and new epidermis.
This fluid helps separate the old epidermis from the new Once that's done, the peeling process begins. To remove the old epidermis, the snake rubs its head against any hard surface. It creates a tear either near the mouth or near the nose.
Then she pulls and snakes her body against any hard surface. And slowly slips out of the old epidermis.
Pluto in Houses in Astrology. Each house governs a life area. Pluto in houses shows in which life area you experience deep transformation and life-changing events. This planet in astrology is associated with trauma and intense pain, but also regeneration and rebirth.
There was a lot of excitement in the space community in 2015. That's because the best picture we'd ever had of the Pluto system was this one. Hubble squinted its lens at Pluto too, but it's so small and far away, the best it could see there were a few flecks of color.
But in 2015 that all changed. That's because the New Horizons spacecraft flew past the dwarf planet after a nine-year voyage and had never seen a detail and fidelity of Pluto and its moons like us before. So the question is, what did the New Horizons probe see and discover during its flyby of the Pluto system? I'm Alex McColgan and you see Astrum.
Stay with me in this article and I'll show you all the highlights from the New Horizons mission to Pluto, Pluto was the last of the traditional 9 planets to be explored. This was due to its distance from us, but also because - can you believe it - it was not viewed as a very interesting celestial object. Fortunately, the team at New Horizon has been hard-pressed to get approved for this mission, and in 2006 New Horizons launched as part of NASA's New Frontier program for mid-budget space missions.
The goal of the mission was to get to Pluto as quickly as possible, and as such, New Horizons was the fastest launch ever. It was a light spaceship on the most powerful rocket of the time - the Atlas V. It whizzed on in just 9 hours Moon over.
The Apollo missions lasted 10 times as long. On its way to Pluto, it used Jupiter as a gravity assist, who shaved 3 years before the arrival time. It also used Jupiter as a test run for its systems and took some notable articles and images of the planet and its moons.
After this successful test, New Horizons went to sleep to prevent its instruments from wearing down until its approach in 2015, the team brought the systems back online and the spacecraft sent back images of the Pluto system every day. This was an incredibly exciting time for history enthusiasts to watch. We began to get clues about what Pluto might look like and see how different Pluto was from its largest moon, Charon.
Every day the resolution got higher and more details could be seen. Yes, there were other scientific goals for the mission, but the most interesting thing about me was what it looked like. Soon something that looked like a heart shape could be seen on the dwarf planet! On July 14, the New Horizons probe approached just 12,500 km from the surface from Pluto controllers did not get an immediate look.
First, the probe was too busy taking many photos during the flyby to send it back immediately. As soon as the data transfer began, they had to use the slow uplink speed of only 1 kbit / sec. In addition, there was a 4.5 hour latency between the spacecraft and Earth.
But what it saw and sent back was spectacular: mountain ranges, ice plains, glaciers and an atmosphere. It also had a good view of some of Pluto's moons covered in detail during that flyby. One of the first things that was observed about Pluto is its unusual relationship with its moons.
First of all, Pluto's largest moon, Charon, orbits very closely around Pluto and is also very large by comparison. This means that the center of gravity of the two objects, or in other words, their center of mass, is outside of the primary object. They actually both circle around a point in space.
Not only that, but both objects are also linked by tides. That is, if you stand on one, the other does not move from that point in the sky. This is very unusual because while some moons are connected to their mother planet, the planet is not also connected to the moon.
Visually, Charon is very different from Pluto, much darker. This implies that they are not of the same origin. The rest of Pluto's moons are very small and only a few kilometers in diameter.
Their orbits are exceptionally circular and are all coplanar with the orbit of Pluto. The largest visible feature on Pluto is this huge heart shape, which struck the world when it first came into view. Since then it has been called Sputnik Planitia.
It is the size of Texas and has a strong color contrast to the surrounding area is a huge ice plain. In fact, during the flyby, it was confirmed that 98% of Pluto's surface is nitrogen ice. On average, the temperature on the surface of Pluto is -229 ° C, which means that water ice would be rigid and brittle.
On the other hand, nitrogen ice behaves like water ice on earth at this temperature, so it can flow as a glacier. This is especially seen at the edge of the heart, glaciers flowing into the gaps around the craters and mountain ranges. The ice plains themselves have huge polygon shapes over the entire area.
There are also no craters, which means it must be a relatively new feature or one that is constantly being renewed. It is maybe only 10 million years old. The polygonal cells show ridges that are mainly caused by sublimation, the process by which an ice turns directly into a gas.
Although not known for certain, Sputnik Planitia may have formed from an impact, and ice filled the crater from a potential subterranean liquid ocean. This filled basin is actually causing a positive gravitational anomaly. A gravity anomaly is when gravity is different at one point than elsewhere on the object.
The ice sheet faces directly away from Charon, which would align it with the object's tidal axis. Due to the short distance between Pluto and Charon, tidal effects are very strong on both objects. This could be the reason why Pluto is bound to Charon by tides and the two objects cannot look away from each other.
Around the ice plains are huge mountain ranges made of water ice, which, when viewed from the side, are spectacular. Water ice is the only type of ice discovered on Pluto that would be strong enough to support heights of several kilometers at this temperature. Found under the mountains on Pluto, there could also be cryovolcanoes, one of the most likely candidates is Wright Mons.
It is 4 km high, one of the highest peaks on Pluto, and there is a large depression in the middle. Cryovolcanoes could be a determining factor in Pluto's young surface. Another obvious feature of Pluto is the dark material that appears to be scattered on the surface in some areas.
The largest such area is called the Cthulhu Macula seen in this picture. The dark color is believed to be a deposit of tholines, a type of tar made up of hydrocarbons that have interacted with sunlight. Similar deposits are found on one of Saturn's moons, Iapetus, too see, hence the process has been seen elsewhere in the solar system.
The region on Pluto is much more cratered than the heart, suggesting that the surface there is much older. In the center of the Cthulhu Macula, mountain ranges can be seen by the presumably methane ice topped. Methane seems tly condensed at higher altitudes on Pluto than frost.
The last surface feature I'll mention here is this region called Tartarus Dorsa. It's a sprawling, very distinctive collection of 500 meter high mountains that resemble snake skin or tree bark. If that's true, Pluto is the only place in our solar system other than Earth where they were observed; even on Earth they are very rare but some can be found in the Atacama Desert and other arid high altitude regions on Pluto are much larger and cover a much larger area than on Earth.
We can only imagine what they look like up close. For me, the most impressive discovery that New Horizons could confirm was that Pluto has an atmosphere, but the images are incredible. Due to Pluto's small size and weak gravity, the atmosphere appears to stretch high above Pluto's surface.
The earth's atmosphere is much more massive and dense compared to Pluto and it hugs the planets comparatively tig htly because the gravity is much stronger. The atmospheric pressure on Pluto is exceptionally low, but about 10 microbars or 100,000 to 1,000,000 times less than the surface pressure on Earth. It is believed that if the temperature rose and the surface ice sublime into gases, the process could increase the pressure to as high as 18 to 280 millibars, three times the surface pressure on Mars and a quarter of the surface pressure on Earth we saw in the ice plains.
The last time was Pluto. This atmospheric density was suspected 900,000 years ago. At this pressure and temperature, the conditions could even be right for the formation of liquid nitrogen on Pluto's surface.
Some evidence of this could be found here in what appears to be a frozen lake. In any case, Pluto's atmospheric density can fluctuate by a factor of four within a year due to seasonal fluctuations. This is a massive contrast to other solar system objects, with atmospheres that generally remain pr etty consistent.
The atmosphere is made up of the same ice found condensed on the surface, namely nitrogen, methane, and carbon monoxide. The other fascinating discovery New Horizons made about the atmosphere is that it has up to 20 layers of haze. Haze layers themselves weren't unexpected, but the amount of them was.
In some of these images they can be clearly seen and appear like thin layers of fog. In this photo you can see sunlight streaming through such a layer, the shadows from the mountains clearly in contrast to the sunlight shining through the haze. The layers do not seem to be level on the planet.
Here you can see that layer of haze high above the surface, but on this side of the picture it touches the surface are the most breathtaking photos of Pluto, and I purposely saved them until the end. You can really appreciate the depth and size of the mountain ranges; Pluto almost looks like a toy replica because of the extreme topographical relief, but these mountains look so high because Pluto is so small and its gravity is not strong enough to pull it down article.

The 6th, 7th, and 10th are bad houses for the Sun. The Moon, the Jupiter and the Mars are the planets friendly to the Sun, where the Saturn, Venus, Rahu and Ketu are enemies. The first is the Puccka Ghar, the permanent house and the house of exaltation of the Sun, whereas the 7th house is in the house of debilitation. .
The pandemic sparked a boom in the housing market, with home sales reaching their highest level since 2006. I know I've spent a lot of time reading Zillow. An insatiable demand in the housing market that is causing sales to skyrocket, according to well-known housing expert, as new home sales are up 19 percent from last year.
People generally look at a house that they want to buy or build. Your first question isn't whether you have sprinklers in this building or look around and see this beautiful forest and say, oh my god, will it burn in two years? 2020 also meant many natural disasters. It was the worst fire season in U.
S. history, and there were over a dozen storms, each costing over a billion dollars, and we're not going to be able to build fireproof houses, non-flammable fireproof houses, because by and large no one wants to live in them. Building a resilient nation saves money, protects the environment and saves lives.
In 2019, nearly a million new people were displaced due to climate disasters in the United States. The good news is that that number went down from one point two five million in 2018 and one point seven million in 2017, which is a very safe product that makes people's lives so much better. Could we do better? Absolutely.
We can always do things better, cost is a big thing, I know it was for me when I did my Zillow research, but I'm lucky enough to be able to afford an apartment with decent security, like those fire sprinklers . So America needs to get many people into homes that can quickly withstand the growing wrath of natural disasters. But is the US approaching building houses completely wrong? And how should houses be built in the USA? Over 15 million privately owned new residential units were completed in 2020.
These should have been built to the building codes and standards of the local regulatory authorities, usually based on the guidelines of the International Code Council or the ICC. The codes basically say if you have this type of function inside a building, in this type of building, you can use these standards to meet our level of security, hygiene, etc. The first thing to do when building in an area is to familiarize yourself with the exact regulatory measures that will affect the design and construction process at that particular location.
Then the specifics, you also check the code, although we at FEMA are active in this process and are committed to promoting these hazard-resistant building and fire regulations down to the local level in order to adopt, adopt and implement these new codes and standards. Industry experts try to keep pace with technological changes and consider evolving environmental factors when developing codes. Every three years they republish their codes that review these things in a public consultation format that is then returned to the entire membership.
They have a ballot to vote on whether to introduce this code change. I think one of the biggest challenges in a code development process is that there are all sorts of competing interests and needs. And that's really important.
If you have a code change advocate and you are trying to drive that code change forward, you need to be in the process. These codes are enforced at the local level. Penalties can include revoking permits or holding on to construction and construction time is money.
A thousand dollars added at any time to the price of a new home will deter 153,967 households from buying that home. Just a thousand dollar increase. Faster construction could help save money in the short term but be devastating in the long run.
The last hurricane we saw in Florida with that one house on the beach was a pretty interesting solution. It was an extremely expensive solution, but it was a lot less expansive than the solution all of their neighbors had when they ran out of houses. Since the I-Codes, the international codes, were first issued in 2000, for example, municipalities that adopted them have saved the country approximately one point six billion.
That's a B billion on average. Analyzed damage from floods, cyclones and earthquakes. Building to withstand the forces of nature can be difficult, especially as our understanding of the environment changes.
If you want to buy a house, the best thing you can do from a flood perspective is to know what your current risk is from the current environment and how it will develop over the next 30 years. And flood risk is not a static one-time thing to look at, an ever-evolving risk that continues to grow exponentially in some parts of the country. Since building codes can change frequently, sticking to them is easier said than done.
For example, depending on when a house is being built in a community, different flood or fire regulations may be required. When you have a large church, you may find that you are building under different regulations. And what is also pretty easy to assess is the cost increases.
For example, homeowners can invest in resilience measures to stick to the code rather than buying a brand new home. As we work to address both the existing structure and new homes, we find that sometimes there is so much focus on the new that it is way above the percentage the price tag should be. So we cannot bear this burden for new homes because we are losing too many first-time buyers and first-time buyers.
There are examples across the country where communities have assessed the risk and then adopted resilient buildings codes to remedy it. For example, a fire cannot cross the street if none of the embers ignite on the other side of the street. Communities at risk of flooding may choose to dig trenches in the street to avoid catching rain, rather than letting that flood into a home.
So what we want to make sure is that we can eliminate most of the ignitions and, in densely populated areas, do so with very limited or no window exposure between houses. And we can make the exterior materials non-flammable, including our eaves and the laying of our eaves, for example by using fiber cement so we can have fiber cement on the walls. We can order a non-flammable brickwork like block or something on it, and then use a non-flammable material for extinguishing and boxing OKAY.
Non-flammable roof which is very helpful. Flooding is a little more difficult than fire, but the flood level provided by the National Flood Insurance Program offers some guidance for stakeholders. I would say that from my point of view it is less about whether we build the houses wrongly, but rather where do we build these houses? So if you look at things from FEMA and the special flood hazard areas they come with a base flood height.
These base flood heights are based on amazing engineering studies they were doing at the time. The problem is that about 11 percent of these studies date from the 1970s and 80s. And when you consider how the environment has changed since the 70s and 80s in order not to include this in the new ground flood height and where we should think about building and why one is beginning to understand why that? can be a problem.
In addition, there is a whole part of the country that has no regulations within a specific flood risk area because it has never been mapped. The codes can solve anything. The behavior of a resident plays a major role in preventing the fire from spreading.
It doesn't help us if we leave our firewood on the deck for the entire fire season. It doesn't help if we have patio furniture that is flammable by fires next to our viewing windows. Research like Cohen's can save lives and billions annually.
It is also important to know where buildings are being built. There is much that the individual homeowner can do to prevent a fire from actually spreading further and causing more damage than simply taking no action or maintaining your yard and other things in a similar manner to a flood where you are Increase your home, or you can put in backflow preventer or have sandbags and the like ready for those flood events when you know they are coming. The good news is that natural disaster displacement is on the decline, largely due to better research and innovation to address this problem.
Our perception of the wildfire rolling through the community like a tsunami of hot gases is not what is happening in reality. We have also had significant successes in improving fire safety in the past. I don't know about your apartment, you can see a sprinkler head in the background.
That's why. And that was built into model codes. To some extent, I wish it was stronger, but there are those who think this is a burden.
It's the cost impact problem. It is difficult in some communities because of water supply problems. There are problems with it, it's not perfect, but it's certainly better than doing nothing.
We have created a national flood model for the entire contiguous United States that can be applied to a single property. So based on the building type, the height of the building, the value of the structure and our flood model, we can use the army corps of engineers, so-called depth damage curves, to know how much water would correspond to what damage to this water structure and calculate that in no time and pass it on to you as a user. So now you know not only how much risk you are, but also what is likely to cost you if this event occurs.
Cohen is working with state and local officials to better educate builders about the spread of forest fires through his research to stop ignition zones at home. Basically we have to define the problem as a structural ignition problem, not as a forest fire fighting problem. We have many decisions that we can effectively make to change the local conditions of the home and its immediate area.
And we have no way of controlling this extreme wildfire. These efforts are also fully supported at the federal level by FEMA. I really want to encourage people to go to the FEMA website, download the app, go to the US Fire Department website and download the information.
There is a tremendous amount of great information out there for individuals to help them be resilient before, during, and after a disaster. Architects and builders suggest that consumers like me need to adjust our mindset to include safety as a top priority, the adjustments necessary to stay longer in their homes, slowing the flow of climate migration and having better financial investments. People see the events, the forest fires, the floods, the daily news that someone died in a house fire, but it doesn't get stuck, it doesn't change their perception and that is, to some extent, why architects do their thinking Run to say yes, you could have sprinkler systems in this entire building and be reasonably certain that your family will be safe for the next 50 years.
How long do Pluto transits last? On average, Pluto spends fifteen years transiting a house I know this to be true since my mega-Pluto transit began with Pluto entering my 6th house in 2006 and will end with the planet crossing my Descendant in a year. .
Moon is the Lord of 4th house, stands exalted in the 2nd house of Taurus and becomes debilitated in the 8th house of Scorpio. The Moon provides very good results if placed in houses 1, 2, 3, 4, 5, 7 and 9 whereas the 6th, 8th, 10th, 11th and 12th houses are bad for the Moon. .
The main advantage of a south-facing house or garden is the amount of sunlight you'll enjoy. As the sun rises in the east and sets in the west, the south side of any house will see the most hours of sunlight during the day especially in the Northern Hemisphere so a south-facing garden takes advantage of this. .
Sun is King, Mars is the Warrior and Saturn is the Servant! In the zodiac signs too, Saturn is debilitated in the first house Aries, owned by Mars and the Sun gets exalted here. The 3rd house has the potential to become the worst house of the horoscope as it is linked to the desires of the dual mind. .
Homes that are oriented to the north typically receive most of their direct sunlight in the back of the building. In warmer climates, north-facing homes can have the benefit of reduced cooling costs when temperatures climb in summer.
West-facing walls receive the strongest sun at the hottest part of the day. Check that there is no significant detrimental overshadowing (of both windows and roof where photovoltaics and solar hot water may be located) by adjacent buildings and trees. .
Typically a south-facing home gets sun for most of the day, especially at the front of the house, and is therefore usually brighter and warmer. A north-facing home gets sun at the back of the house and is typically darker and naturally cooler than a south-facing one. .
The most important place in the house is its entrance which should be east facing as this is known as auspicious direction. The north direction of the house should not be blocked as this is known for prosperity. Slop should be directed from south to north or from west to east direction.
