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.

I don’t know about you, but if I’m told that billions of planets are freely roaming around in our galaxy, I start to feel slightly nervous.
Because it’s one thing for small asteroids, interstellar wanderers – such as Oumuamua, for example – to come into your house – into our solar system, I mean – and take a ride and then leave without doing any damage, it’s quite another to think that a large planet might come in like a cannonball that would also be capable of disrupting orbits, if not doing much worse
You are wondering what the hell are we talking about?
Well, about what certain astronomers are going around saying, convinced that such planets should not be considered a very rare freak of nature, as was the case until a couple of years ago … but the result of a cosmic mechanism that in our galaxy acts on a large scale, and that of these starless planets is capable of churning out hundreds of billions of them!
So am I right or wrong to feel a tad worried?

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.

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.

On Mars, there is a crater that bears the strange name of Jezero, a term that in several Balkan languages is used to indicate a lake region, and which is also the name of a very small town in Bosnia that rises near a lake where a small river flows. Just a case? Not really… For some years now, the International Astronomical Union has decided to name the most geologically or biologically interesting Martian craters under the name of small towns and villages on Earth.

The logic of the choice lies in the fact that the crater in the past was also a lake full of water, and moreover a lake where an ancient and winding Martian river flowed. An environment where, according to NASA experts, ancient organic molecules and other potential signs of microbial life could have been preserved in the water and sediments that flowed in the crater billions of years ago.
And it is precisely among those sediments, where once the river water widened into swamps, that next February 18, Perseverance, the new automatic robot launched last July 30 from Cape Canaveral, will settle down to finally give an important answer to the eternal question about the possibility that there was or still is life on Mars.
Almost a decade of preparation, a ton of weight, seven scientific instruments, a robotic arm, a support drone, 23 high-definition cameras, the first microphones ever brought to the Red Planet…
The mission, which as a whole is called Mars 2020, is one of the most ambitious ever conceived by NASA in recent years. Reaching Mars is not easy, and getting something down on its surface is even more complicated, as space agencies who have tried so far know. The United States is in fact the only country to date to have successfully made controlled landings, bringing several rovers to Mars. The largest of them, Curiosity, is still active after its arrival in 2012 and is still collecting valuable information about the planet.
The Spirit and Opportunity rovers have shown that liquid water once flowed on the surface of Mars. Curiosity discovered that four billion years ago conditions on Mars were favorable for the development of life as we know it. Perseverance will look directly for signs of past life.

How do we search for exoplanets?
With the global warming and sea pollution constantly growing trends, the future of Earth might be at serious risk. In addiction, the overpopulation of some regions might cause a global food crisis in nearly 30 years.
These are just a few reasons why some brilliant minds such as Jeff Bezos and Elon Musk have started to plan a colonization of other planets like Mars, launching several rockets of their futuristic companies Spacex and Blue origin.

What are exoplanets? How can we reveal their presence? Is it possible to find a place similar to our beautiful Earth? These and other great questions will be discussed in this video. Stick with me and I’ll tell you everything in a moment.
It’s surely interesting to wonder about a possible future destination for everyone, but in order to understand how this can be done we need to take a step back and try to look at our planet: Earth.
We all agree, except for some sceptics, that it has a spheric shape and that it has two main rotating motions: one around the sun, which causes the existence of four different seasons, and another around his axis, which is the source of day and night.
But why we use to call Earth as a planet? What is a planet?
The first revolution around the sun takes more time than the rotation around the axis, but this is not something that Earth shares with other “colleagues” of the solar system: for example, on Venus a year lasts less than a day. So what do all planets have in common?
They all complete a close motion around the Sun and they have a stable shape typical of a certain mathematical equilibrium called hydrostatic equilibrium. Practically speaking, this is the reason why all planets are spherical.
Addictionally, to gain the definition of planet a body must have a clean orbit without rocks or other astronomical detritus. As a matter of fact, in 2006 Pluto was declassified to the rank of dwarf planet because Eris was discovered, a big satellite that had nearly 27% of Pluto’s mass.
Finally, a planet must have less than thirteen times the mass of Jupiter, the biggest one in the solar system.
In parallel, an exoplanet is an astronomical object orbiting around a star different from the sun, but with the same features we already listed.
Is it easy to detect the presence of an exoplanet? Definitely not. They’re not simple to find and only a bit more than four thousand have been discovered after 1992, when the first two planets were seen orbiting around a pulsar. Even if this number seems really big, it’s totally incomparable with the amount of stars discovered, which is almost 500000 only in the milky way.
Stars are way easier to be discovered and catalogued as they shine on their own. On the contrary, planets happen just to radiate some tenuous infrared rays, that are surely not capable of reaching our detectors on earth. As a matter of fact, just less than 30 exoplanets have been detected by this technique called “direct imaging”.
Given the fact that it’s not possible to measure their emission, how can we “see” a planet? Through indirect methods. Physicists love to study little changes in the radiation of the major star that are capable of revealing the presence of one or more planets.
Let’s investigate the main techniques that are commonly used in astronomy for searching exoplanets.
The first one deals with radial velocity. A planet has certainly a consistent amount of mass that weakly attracts the star, which has some slight displacements due to its presence. More precisely, both the star and the exoplanet are orbiting around the center of mass, a virtual point on the line that connects the two bodies, which is located near the heaviest one. This movements of the star can be well detected through a very common technique: redshift. Have you ever heard anything about this?
