Planet Nine: Will We Ever Find It?



Planet Nine: will we ever find it?
How many planets are there in the Solar System? 
Well, it seems not so easy to say. Our current classifications say there are 8 planets.
The four smaller inner planets, Mercury, Venus, Earth and Mars, are terrestrial planets, being primarily composed of rock and metal.

But now astronomers are asking themselves if there could be a 9th planet. 
Why is that? Well, observational data show an unusual clustering of orbits for a group of Trans Neptunian objects. (TNOs). These tend to make their closest approaches to the Sun in one sector, and their orbits are similarly tilted!
Follow me on this video to get to know more about the famous Planet Nine!

Planet Nine, sometimes incorrectly referred to as Planet X, is a hypothetical planet in the outer region of the Solar System. 
Does it exist?
Well, we don’t know yet.
As we said, its gravitational effects could explain the unusual clustering of orbits for a group of extreme trans-Neptunian objects (eTNOs), bodies beyond Neptune that orbit the Sun at distances averaging more than 250 times that of the Earth. These eTNOs tend to make their closest approaches to the Sun in one sector, and their orbits are similarly tilted. These alignments suggest that an undiscovered planet may be shepherding the orbits of the most distant known Solar System objects.
But how Planet Nine would be, if it existed?
Based on earlier considerations, it would be a super-Earth sized planet, with a mass of five to ten times that of the Earth, and a huge elongated orbit, 400 to 800 times as far from the Sun as the Earth. If the Sun was in New York and the Earth was in Washington, one would have to cover about ten times the distance from New York to Beijing to reach planet Nine!
Konstantin Batygin and Michael E. Brown suggested that Planet Nine could be the core of a giant planet that was ejected from its original orbit by Jupiter during the genesis of the Solar System. Others proposed that the planet was captured from another star, was once a rogue planet, or that it formed on a distant orbit and was pulled into an eccentric orbit by a passing star.
Anyway, if it existed, we would not have any doubt about its planet nature. 
In fact, according to IAU (international astronomical union), a planet is a celestial body which: 
1)is in orbit around the Sun;
2)has sufficient mass to assume hydrostatic equilibrium (a nearly round shape);
3)has “cleared the neighbourhood” around its orbit.
(Among other things, this definition caused Pluto to no longer be classified as a planet, a change from how it had been widely considered until that point. We want to spend some words here reporting a fun fact: when Pluto was finally classified as a dwarf planet, some people joined the “Pluto is a planet” protest. Here are some photos taken during those protests.)

If Planet Nine exists, its mass is sufficient to clear its orbit of large bodies in 4.6 billion years, the age of the Solar System, and its gravity dominates the outer edge of the Solar System, which is sufficient to make it a planet by the above definition.
As of February 2021, no observation of Planet Nine had been announced.

But if planet nine exists, why can’t we find it?

The answer is that while we can see the effects of this hypothetical planet, finding it is a different matter. 
In fact, in order to find planets, astronomers make use of various methods.
The most famous, and perhaps the one you’ve heard of, is the transit method. From our position, if a planet crosses across its star, we can see the dip in light that causes.
Measuring three of these dips, we can work out the mass and orbit of the planet. Not all planets transit their star with respect to us, however, so we can’t use this for every star.
Another method is called the radial velocity. This involves noting the tiny, tiny gravitational tug a planet exerts on its star. For smaller planets in wide orbits, this is incredibly difficult, but for larger planets in tighter orbits, such as hot Jupiters, this can be quite useful.
Then there’s gravitational microlensing.

What If We Relocated Humanity to Proxima B?



Even though humanity might not have to leave the Earth in your lifetime, we should start preparing early on. Not only could it take centuries to set up the relocation program, it would take generations to move to a potential new home. That right there is Proxima Centauri b, or just Proxima b. It’s the closest potentially habitable planet out there, its temperatures are in the bearable range, and it could just have the right breathable atmosphere. We only have to get there. How long would our journey last?

10. The Discovery of Ariel
In terms of its finding, Ariel was discovered on October 24, 1851 by William Lassell, it is named for a sky spirit in an Alexander Pope’s story and Shakespeare’s The Tempest. Which is not too uncommon given the power that literature and mythology have in regards to naming things like this.
Both Ariel and the slightly larger Uranian satellite Umbriel were discovered by William Lassell on the same day believe it or not.
9. Its Surface
All of Uranus’ larger moons, including Ariel, are thought to consist mostly of roughly equal amounts of water ice and silicate rock. Carbon dioxide has also been detected on Ariel. Which is important in helping determine various things about the moon itself.
8. Rotations and Orbits
Among Uranus’s five major moons, Ariel is the second closest to the planet, orbiting at the distance of about 190,000 km, or over 118,000 miles.
7. Observation and Exploration
The only close-up images of Ariel were obtained by the Voyager 2 probe (one of the most important scientific tools in the history of the space program), which photographed the moon during its flyby of Uranus in January 1986.
6. Atmosphere
Despite there being carbon dioxide on the moon of Ariel in some capacity, there is no detectable atmosphere or magnetosphere that we can find.
5. Surface Temperature
Measurements have shown that Ariel’s surface temperature rises and falls quickly with the coming and going of sunlight, without a “thermal inertia” lag. That supports the picture of a porous surface, which would tend to insulate the moon and keep the subsurface from heating up. This texture could be the result of eons of micrometeorite strikes tilling the soil.

What If We Cooled the Earth with Solar Power?



Why do solar panels look so different these days? And why have we started installing them on top of mountains, using them to pave our roads, and putting them in the middle of our oceans? Well, if we cover enough of our planet in solar panels, we’ll have a good chance of halting the planet’s rising temperature, and maybe even cooling it a couple of degrees. But how would that work? Could we use the panels to reflect the Sun’s heat into space? How many solar panels would it take to power everything on the Earth? And why could a solar-powered planet be bad for the environment?

Why  Space Research  Is So Important!

Why Space Research Is So Important!

In recent years, people’s interest in all countries on the planet in space exploration has soared.
Many controversies have been raised regarding whether money should be spent on Space research while there are many problems in our inhabited planet, earth and especially in Humanity. There is poverty, financial issues. And still so much attention into Space exploration. Why?
Join me I show you reasons why Space research is very important.

——————————————————————————————-
We have seen NASA announcing findings in other planets, solar systems and companies such as SpaceX undergo space projects. For instance we have determined the approximate age of the universe, we found water on Mars, we discovered the first exoplanets in 1992, between the years of 2004 and 2005 three new dwarf planets that exist in our solar system came into our attention and so much more.
But many keep on claiming. What is the point in all of this?
In order for a space exploration to happen, much money needs to be spent. For this reason many people seem to raise questions when it comes to space exploration whether money should be spent on space missions while there are many issues that are happening in our planet that we haven’t solved, and need financial support. So instead of exploring space, money should be spent for Earth’s needs.
Some others consider that, since we already visited the moon in 1969, we don’t need space travel anymore. isn’t it enough?
Well, there are many reasons why space exploration is important and I will try to explain my point of you on this topic and why space research is more significant than we think and vital to humanity.
Before we continue with the significance of space exploration, be sure to like or dislike the video so that we can continue improve and make these videos better for you the viewer. Plus, be sure to subscribe to the channel so that you don’t miss any of our weekly videos!

Now let’s start analyzing our topic.
Well Universe!
Can you imagine the feeling the astronauts who first landed on the moon must felt looking back at the earth? Breaking through into space travel, leaving earth and defeating gravity, taking steps on the moon?
I bet the feeling would be unique! As they had the opportunity to see earth from a distance and be the first ones to acknowledge it! Imagine being in there position! I think many are jealous that they didn’t live this experience. For them this incident can’t be compared with anything else, and while we didn’t know at this time, this mission advanced our Humanity, and raised the interest on figuring out the Universe! Only goo results can come out of this as we are learning who we are and becoming strong.
But what is the real motive behind exploration. Why do you want to explore and go out of our comfort zone instead of carrying only about what is going on on Earth?
Well, the main reason why moon landing happened in 1969 and, is because humans are driven to explore the unknown, discover new worlds and push the boundaries of the scientific limits. Like it or not, we are by nature explorers who want tο push further and challenge the boundaries of what we already know and we want to learn always something new that can cause a whole new reality. We love exploring the world, travelling abroad visiting other countries and places, collecting memories and experiencing feelings. The same happens on a bigger level by exploring the universe. We are never satisfy and we always want more. People try to achieve these feats for reasons that are not necessarily rational. A few years ago we confirmed the existence of dark matter and we couldn’t do that without space exploration. What is the value of this knowledge? It’s hard to guess today.
And what keeps us going is the fact that we can discover everyday something new and in this way we advance human race. Imagination remains our most powerful attribute and we don’t want to stay stable in only one thing. That is what we do. We always explore. We overcome obstacles not because we have to, but because we want to. We can’t live without progress and curiosity is in our blood.
In this point we need to make clear that exploration isn’t just only about curiosity though, as exploration is necessary for advancement in general. If it wasn’t for the Space exploration we wouldn’t have advanced technologies.
The space research has led us to expand our scientific knowledge and have development of various technologies that improve our lives on Earth and also the economy. The world that we have created today, is the result of several years worth of knowledge, much of which has been built through exploration.

9 Strangest Galaxies In The Universe!

9 Strangest Galaxies In The Universe!

Subscribe for more videos:

From galaxies that are shaped weirdly, to ones that have unique properties, join me as I show you the strangest galaxies in the universe!
9. ESO 137-001
I want you to think about the “shapes” of universes. Depending on the pictures you look at, you likely think of things like the spirals that many galaxies are believed to be shaped as. But in the case of ESO 137-001, that isn’t exactly the case. Because this galaxy…is shaped like a Jellyfish.
No, really, the spiral form of the galaxy is still there. BUT, it also has a “tail” that is formed by stars that are in its “wake” if you will, and it’s quite a tail as it extends over 260,000 light years into space!

8. NGC 1052-DF2
Ok, this one was weird in context as I’ll explain. You see, in 2018, the Hubble Space Telescope (one of the most important pieces of technology we have in terms of mapping space) found a galaxy known as NGC 1052-DF2. When scientists and astronomers looked at the galaxy though, they felt that something was missing. Mainly, there was a lack of Dark Matter, and that should’ve been impossible.
“Dark matter is conventionally believed to be an integral part of all galaxies — the glue that holds them together and the underlying scaffolding upon which they are built,” explains co-author Allison Merritt from Yale University and the Max Planck Institute for Astronomy, Germany.

7. MACS 2129-1
The place known as MACS 2129-1 is definitely a galaxy that stands out for a whole host of reasons. Not the least of which is because it’s what’s known as a “No life Galaxy”. To be clear, there is life in the form of stars and planets within it, that’s not the issue. But, the galaxy is no longer “active”, meaning that it’s not making anymore stars despite it being over 10 billion years old.

6. The Andromeda galaxy
Arguably the most famous galaxy in the universe outside the Milky Way, the Andromeda Galaxy is one that has led many people to wonder what is just outside our own galaxy, mainly because it’s our neighbor. Not just that, it’s our largest neighbor by a wide margin, and there’s a very good reason for that. Mainly, the Andromeda Galaxy is known as a “cannibal galaxy”.
What does that mean? Well, as the title describes, it actually collides with and devours other galaxies in order to make itself bigger:
“Andromeda has a much bigger and more complex stellar halo than the Milky Way, which indicates that it has cannibalized many more galaxies, possibly larger ones,” lead study author Dougal Mackey, an astronomer at Australian National University, said in a statement. “Knowing what kind of a monster our galaxy is up against is useful in finding out the Milky Way’s ultimate fate.”

So, remember the Jellyfish Galaxy we talked about a little while ago? Well, meet its cousin, the Tadpole Galaxy. This one is very on the nose in terms of its name because of the fact that it has a LONG tail that is attached to a body that reminds scientists of a tadpole. So looking at this you may wonder, “How did this happen?” According to the ones who found it, it’s a remnant of sorts from a galaxy that collided with another.
4. W2246-0526
If this list has shown you anything so far, it’s that the state of our universe is very much in a state of flux. But what you might not realize is that while some galaxies do collide with each other, others go and just steal things from one another. They alter shapes, steal stars, and sometimes even become brighter. Which is the case with W2246-0526:

3. Little Cub
Found in the Ursa Major Constellation, there is a dwarf galaxy known fondly as the “Little Cub”, and it’s one that has scientists very curious despite its impending doom. Why is that? Because the “Little Cub” as it is known is a galaxy that is dormant, and it has remained unchanged for about 13.7 billion years. If you know the alleged history of the universe, that would mean that it has been the same since the beginning of the universe more or less.

2. The Petal Galaxy
Let’s dig back into the visuals of galaxies for a bit. There are many galaxies out there in the universe that are growing at various rates as we’ve shown. But ESO 381-12 is different. Not only is this one growing, it’s growing in a way and in a shape that is truly baffling scientists. How so? Well, it looks like a flower in bloom, and the “petals” as they are known aren’t symmetrical.

1. Messier 83
15 million light years away in the Hydra is the galaxy known as Messier 83, and it is a galaxy that has caught a lot of people’s eyes. Mainly because those who have looked at it noticed that it has “two hearts”:

8. The Scope Of Our Own Solar System
Before we look beyond it, let’s take stock of our own solar system and what it all is like. There are 8 definitive planets (and more than that if you count Dwarf Planets like Pluto), we have one star, The Sun, that we orbit around, and within the confines of our system are asteroid belts, various rocks of various sizes, tons of solar rays and radiation, and a whole lot more.
Just in our solar system there is a LOT of stuff to explore. Which is sometimes hard to find because the length of our solar system is about 287.46 billion kilometers long. And even in the year 2020 we’re STILL finding out things about our solar system that are shocking and surprising. But of course, the main goal of humanity as a whole is to do what many have thought is unthinkable. To go BEYOND our solar system and to not just see it, but explore it, and live upon it. To truly become a species that is intergalactic instead of just living in one very small part of the universe.
7. What Lies Immediately Beyond Our Solar System
So let’s posit for a moment that you are able to go and get out of the reach of our solar system. Behind the Kuiper Belt, beyond the Heliosphere, what are you going to find when you reach that edge beyond? What will you see? What will you experience?
The honest and very simple answer…is nothing. Because you’ll be in what is known as Intergalactic Space. Or, the space between galaxies and systems. But to be clear, just because you don’t see anything, doesn’t mean that nothing is there.
“If you took a cubic meter, there would be less than one atom in it,” Michael Shull, an astronomer at the University of Colorado Boulder, told Live Science. “But when you add it all up, it’s somewhere between 50 and 80% of all the ordinary matter out there.”
Scientists are honestly deeply interested in this matter, or “Intergalactic Medium” because of how they feel it forms and even replenishes certain systems via the gas that it provides. The reason for this is that the medium is mostly hot, ionized hydrogen (hydrogen that has lost its electron) with bits of heavier elements such as carbon, oxygen and silicon thrown in. While these elements typically don’t glow bright enough to be seen directly, scientists know they’re there because of the signature they leave on light that passes by.
“IGM is the gas that feeds star formation in galaxies,” Shull said. “If we didn’t still have gas falling in, being pulled in by gravity, star formation would slowly grind to a halt as the gas [in the galaxy] gets used up.”
But because of its small numbers, when you’re floating through space, you’re almost literally floating through empty space. Which is why many note that all the planets and stars and celestial objects only fill up about 5% of the known universe. Everything else is minor matter, Dark Energy and Dark Matter.
6. Systems Beyond Our Own
Ok, so let’s say that you are able to reach another system. What would it be like? Well, that would depend on what you land upon.
Because there are at least 100 billion stars in the Milky Way, a spiral galaxy about 100,000 light-years across. The stars are arranged in a pinwheel pattern with four major arms, and we live in one of them, about two-thirds of the way outward from the center. Most of the stars in our galaxy are thought to host their own families of planets. Thousands of these extrasolar planets (or exoplanets) have been discovered so far, with thousands more candidates detected and awaiting confirmation. Many of these newly discovered planetary systems are quite different from our own.
In fact, part of the fun of astronomy in the eyes of many is going and seeing if you can indeed find a new planet, or star that hadn’t been noticed before, and seeing what details you notice about it. In fact, various agencies from NASA to the ESA and more have made their own satellites and probes and such that they’ve launched into space or our atmosphere to try and get better looks at planets and stars and see what we can find.
Some of the highlights for sure are many planets that are “Earth-Like” in structure or form or shape. Numerous kinds of stars from dwarf stars to binary stars, to Pulsars, Supernovas and more. They’ve found black holes at the center of most galaxies, and that’s still only scratching the surface of things.
