The Sun isn’t the biggest thing in our Solar System. And it’s not Jupiter, either. But close. It’s Jupiter’s very own magnetic field. What would it be like if Earth’s magnetic field was as huge as Jupiter’s? How much stronger would our magnetosphere become? Why would it make solar radiation worse? And how could this help you treat anxiety?

What If You Lived on Kepler 22-b?

What If You Lived on Kepler 22-b?



635 light-years from where you are sitting, way out in outer space, lies a planet. The first planet to be discovered inside the habitable zone of a Sun-like star. Its name is Kepler 22-b. When a planet is located within a star’s habitable zone, it means that there is a chance that liquid water exists on its surface. And where there’s water, there’s also the possibility of life. Human life. What would the weather be like over there?

What If Jupiter and Mars Switched Orbits?

What If Jupiter and Mars Switched Orbits?



The delicate balance of the entire Solar System exists in a gravitational dance between planets. Swap the orbits of two of them and you could end up wreaking all kinds of havoc. What would happen to a rocky, red planet stuck between two gas giants? How would Earth react to a gigantic new neighbor? And why would a big shift in gravity trigger an asteroid apocalypse?

What If Uranus Collided With Earth?

What If Uranus Collided With Earth?



It’s been 30 days since Uranus first appeared in the sky. At first, it looked like our Moon had found itself a stellar partner. But then, we understood something much, much bigger was headed our way. What caused Uranus to become so unstable? How could this epic collision change the ice giant? And what’s with this horrific stink? Ugh.

A marshmallow meteorite hurtling straight toward Earth?

How would this sweet space object begin its descent toward our planet? Would the rapid speed of 99.9% of the speed of light, which is 299,792 km/s (186, 282 mps), cause the marshmallow to disintegrate in mid-air?

What would happen if a marshmallow traveling at light speed actually made contact with Earth?

Birth Of Mars Might Be Wrong, Scientists Say!

Birth Of Mars Might Be Wrong, Scientists Say!



From the creation of Mars, to the timeline that is now being reset for it, join me as we explore how the Birth of Mars might be wrong!

Subscribe for more videos:

Watch our “Everything About The Red Planet” Playlist:

I know what you’re thinking, “What do you mean the birth of Mars may be wrong? It’s a planet! And we know how the planets formed!” And yeah, that’s true, but as we explore our solar system and get various readings on the planets, and get a look at their history, we find out that we may not know as much as we thought we did. New research is coming to scientists and noting that the formation of Mars might not be as simple as we projected it to be.
To understand these new finds on Mars though, we have to look back at the birth of the solar system itself. So let’s rewind ALL the way to the Big Bang. When this massive boom of energy and matter came through the universe at large and put various amounts of gasses and other matter all around and just left it there to be formed. Eventually, in regards to our solar system at least, the gasses came together and compacted and that caused a fusion reaction that eventually led to the birth of our star (we’re paraphrasing for time here as we want to get back to Mars).
So at this point in our solar system, the sun is out there in the center of it (in terms of how we think about it anyway) and clearly things are going well. But what about the planets? How did they come to be?
Not so ironically, the same way that the sun was made, just with a lot less fire and such. Because while the sun was going and starting to form, the Solar Nebula (the expanse of gasses within our solar system left by the Big Bang) was still reaching out in all manners, and the sun wasn’t the only thing forming when it was starting to collapse. Through this process, a lot of things were literally just “thrown together”, and it made not just the planets, but comets, asteroids, moons, and many other things that you can find up in the sky.
It wasn’t a “grand creation” by any means, it was more of a “throw it together and see if it sticks” kind of thing, you know?
This is one of the reasons why there are so many objects in our solar system, and why there are so many different kinds of planets. Some of the planets are gas giants because that’s all they had to work with (or they had solid dense cores and the gasses just run to that) and when they were big enough and such, regular matter like rocks and stuff couldn’t stick to it. In contrast, planets like Earth, Mars, and Pluto were able to go and be solid because of the matter that was around them. The gasses of the nebula were start a part of them, but they were absorbed either into the ground or into the very atmosphere itself.
#insanecuriosity #marseverythingabout
The further away from what would be the sun they were, the colder they got, while the closer they were, the hotter they got.
And that’s how the planets looked like they do now, right? No, there was one last “game” to be played, and it was a dangerous in many respects.
I want you to imagine you’re playing a game of jacks. You know, where you lay out all of the spiked objects, you bounce a ball and you try and pick up as many as possible in one bounce? Yeah, that game. Now, I want you to picture yourself about to drop the jacks onto the floor you’re playing on. The act of you dropping them is the Big Bang, and how they stay once they stop bouncing around is the formation of the sun and planets.
Right now, everything is fine, because there’s plenty of space between them, right? Or at least enough space so that they don’t go bouncing off one another. Now though, picture that gravity started to be exerted on them in such a way that they started to move. And not just move in an orbit, but move in such a way that they start crashing into each other. What do you think would happen to the jacks? Exactly, they’d get injured, they’d get broken, and so on and so forth.
That’s technically what happened when everything started to get fully formed. On one hand, you had the sun, which was exuding such an intense gravity that everything started to orbit around it. Then, you had the planets, which had their own gravity, and they decided to try and pull objects to themselves.
As if that wasn’t enough, when the sun went nuclear, it created solar winds which went and pushed just about everything out of the way of the sun and thus sending it careening around the solar system. This “blitz” if you will caused a TON of collisions, which meant that a bunch of planets, moons, and other bodies were damaged.
In fact, it’s believed that one such event caused the creation of Earth’s moon.

A" Gravitational Telescope" Capable Of Showing The Morphology And Surface Of Exoplanets

A" Gravitational Telescope" Capable Of Showing The Morphology And Surface Of Exoplanets



If this will happen it will be thanks to a new project funded by NASA that plans to make a “natural” telescope, based on the property of light to be focused by means of a large mass that acts as a “gravitational lens”.In recent decades thousands of new planets have been discovered beyond our Solar System, the so-called exoplanets. Here you can watch A”gravitational telescope” capable of showing the morphology and surface of exoplanets.

The search for an Earth-like planet orbiting another star is one of astronomy’s greatest challenges. It’s a task that appears close to fruition. Since astronomers spotted the first exoplanet in 1988, they have found more than 4000 others.
Most of these planets are huge because bigger objects are easier to spot. But as sensing techniques and technologies improve, astronomers are finding planets that match Earth’s vital statistics ever more closely.
They have even begun to use a ranking system called the Earth Similarity Index to quantify how similar an exoplanet is to the mother planet. The exoplanet that currently ranks most highly is Kepler-438b, which orbits in the habitable zone of a red dwarf in the constellation of Lyra some 470 light years from here.
Kepler-438b has an Earth Similarity Index of 0.88. By comparison, Mars has an ESI of 0.797, so it’s more Earth-like than our nearest neighbor. That’s exciting but it is inevitable that astronomers will find planets with even higher indices in the near future.
And that raises an interesting question: how much can we ever know about these planets, given their size and distance from us?
To understand the magnitude of the problem, let’s imagine we want to observe the Earth from a distance of 100 light years.
From such a distance, our planet, which has a diameter of about 12,750 km, subtends an arc of just 3 millionths of an arcsecond: an angle 17,600 times smaller than the smallest detail that a large telescope like Hubble, for example, is able to resolve and show us. And this is without considering that, from such a distance, the weak light reflected from Earth would be completely drowned in the overwhelming glare of the Sun.
