Imagine how cool it would've looked irl

- psychology / astronomy / technology / basically anything related to science which is cool

- MUSIC RECOMMENDATIONS PLEASE (use ask for that)

- what else

Makes me think how vulnerable we really are,,, considering how we still haven't observed any aliens yet and how they might as well not exist, life is really precious, but it can be destroyed at any moment,,

The site of impact from the asteroid that killed the dinosaurs 66 million years ago is called Chicxulub Crater

The center of the crater is located near the Mexican town of Chicxulub, after which the crater is named. The crater is larger than 180 km in diameter; this feature makes it one of the largest confirmed impact structures on Earth. The meteorite that formed the crater was at least 10 km in diameter.

The age of the rocks shows that this impact structure dates back to the end of the Cretaceous period, about 65 million years ago.

The impact associated with the crater is implicated in the extinction of dinosaurs, as suggested by the Cretaceous-Paleogene boundary (K-Pg boundary), the geological boundary between the Cretaceous and Paleogene periods, although some critics argue that the impact was not the only reason, others debate whether there was a single impact or whether the Chicxulub impact was one of several that could have hit the Earth at about the same time.

Recent data suggest that the impact may have been created by a piece of a much larger asteroid, which fragmented into a distant space collision more than 160 million years ago.

The car that hit the Earth had an estimated diameter of 10 km, and emitted an estimated equivalent of 96 teratons of TNT. By contrast, the most powerful explosive device ever detonated by man, the Tsar's Bomb, had a yield of only 50 megatons of TNT so the impact of Chicxulub is 2 million times higher and stronger.

IS THERE A PLANET NINE IN OUR SOLAR SYSTEM??

Blog# 161

Wednesday, January 26th, 2022

Welcome back,

Caltech researchers have found mathematical evidence suggesting there may be a “Planet X” deep in the solar system. This hypothetical Neptune-sized planet orbits our Sun in a highly elongated orbit far beyond Pluto. The object, which the researchers have nicknamed “Planet Nine,” could have a mass about 10 times that of Earth and orbit about 20 times farther from the Sun on average than Neptune. It may take between 10,000 and 20,000 Earth years to make one full orbit around the Sun.

This does not mean there is a new planet in our solar system. The existence of this distant world is only theoretical at this point and no direct observation of the object nicknamed “Planet 9” have been made. The mathematical prediction of a planet could explain the unique orbits of some smaller objects in the Kuiper Belt, a distant region of icy debris that extends far beyond the orbit of Neptune. Astronomers are now searching for the predicted planet.

In January 2015, Caltech astronomers Konstantin Batygin and Mike Brown announced new research that provides evidence of a giant planet tracing an unusual, elongated orbit in the outer solar system. The prediction is based on detailed mathematical modeling and computer simulations, not direct observation.

This large object could explain the unique orbits of at least five smaller objects discovered in the distant Kuiper Belt.

“The possibility of a new planet is certainly an exciting one for me as a planetary scientist and for all of us,” said Jim Green, director of NASA’s Planetary Science Division. “This is not, however, the detection or discovery of a new planet. It’s too early to say with certainty there’s a so-called Planet X. What we’re seeing is an early prediction based on modeling from limited observations. It’s the start of a process that could lead to an exciting result.”

The Caltech scientists believe Planet X may have has a mass about 10 times that of Earth and be similar in size to Uranus or Neptune. The predicted orbit is about 20 times farther from our Sun on average than Neptune (which orbits the Sun at an average distance of 2.8 billion miles). It would take this new planet between 10,000 and 20,000 years to make just one full orbit around the Sun (where Neptune completes an orbit roughly every 165 Earth years).

Astronomers studying the Kuiper Belt have noticed some of the dwarf planets and other small, icy objects tend to follow orbits that cluster together. By analyzing these orbits, the Caltech team predicted the possibility that a large, previously undiscovered planet may be hiding far beyond Pluto.

They estimate the gravity of this potential planet might explain the unusual orbits of those Kuiper objects.

Astronomers, including Batygin and Brown, will begin using the world’s most powerful telescopes to search for the object in its predicted orbit. Any object that far away from the Sun will be very faint and hard to detect, but astronomers calculate that it should be possible to see it using existing telescopes.

“I would love to find it,” says Brown. “But I’d also be perfectly happy if someone else found it. That is why we’re publishing this paper. We hope that other people are going to get inspired and start searching.”

“Anytime we have an interesting idea like this, we always apply Carl Sagan’s rules for critical thinking, which include independent confirmation of the facts, looking for alternate explanations, and encouraging scientific debate,” said Green. “If Planet X is out there, we’ll find it together. Or we’ll determine an alternate explanation for the data that we’ve received so far.

"Now let’s go explore.”
