in the future - u will be able to do some more stuff here,,,!! like pat catgirl- i mean um yeah... for now u can only see others's posts :c

⚡️☄️ Ever heard about S2 meteorite impact on Earth and its role in early life evolution?
The S2 meteorite, which hit Earth approximately 3.26 billion years ago, is believed to have played a significant role in shaping early life. According to recent research, S2 had an estimated diameter of 37-58 kilometers, comparable to the size of four Mount Everests. The impact ejected massive amounts of dust and vapor into the atmosphere, blocking sunlight and causing substantial cooling. This temporary "nuclear winter" effect likely led to the mass death of primitive organisms by obstructing photosynthesis and drastically altering early ecosystems.
The meteorite’s impact on Earth's oceans was particularly dramatic. Mega-tsunamis would have stirred coastal areas, distributing nutrients across the water. Additionally, the extreme heat from the impact might have boiled the surface layers of the oceans, creating harsh conditions but also potentially fostering evolutionary adaptations.
🧬 These chaotic environmental changes could have enriched marine nutrient supplies, creating an environment ripe for microbial growth and diversification.
🗺️ Evidence of S2’s impact is found in the Barberton Greenstone Belt in South Africa, where geological layers retain traces of this and other significant impact events. These findings offer scientists valuable insights into early Earth’s atmospheric and crustal changes following such extreme events.

☀️📏 Gliese 710 - The CLOSEST star approach to us!?
👀 There's one faint orange star in the constellation Serpens, named Gliese 710. It can only be seen with powerful binoculars or a telescope. It became famous after the publication of the Gaia catalogs. It turned out that this star is flying towards our Solar System!
In the vicinity of the Sun, about half of all the stars are approaching the Sun at different angles, the other half are moving away from us at different angles. If we analyze the data of all the stars in the latest Gaia DR3 catalog, which are no further than 100 parsecs from us and, at the same time, are approaching us, it turns out that the star GJ 710 has the smallest annual shift in the sky. That is, among the selected stars, this star is most aimed at the Solar System. It has looked practically motionless for many hundreds of thousands of years. Only gradually does its visible brightness increase. Analysis of the spectrum of this star showed that it is approaching us at a speed of 14.4 km/s.
Now this star is in the constellation Serpens, that is, not far from the part of space where the Sun moves relative to neighboring stars. Therefore, it would be more correct to say that the Sun is gradually catching up with Gliese 710 in space.
⏳ In about 1,296,000 years, Sun will fly at a distance of about 0.051 parsecs (0.167 ly, 10.6 kAU) from the star GJ 710. And although this is 350 times further than the distance from the Sun to Neptune, GJ 710 will pass inside the Oort cloud and cause a disturbance in the orbits of objects in this cloud. Some of these objects may rush towards the Sun and arrange a cometary bombardment of the planets of the Solar System.
🔭 The neighboring star will become the 4th brightest celestial object, after the Sun, the Moon and Venus. The Sun will fly past this star, and it will move away from us against the background of the constellation Orion

Hello, stranger! I have to admit, I really love everything about our universe! On my channel you'll find especially comparison videos about
- Our Solar System
- Stars, exoplanets, black holes, etc.
- Galaxies, clusters and other astronomical structures that are unimaginably huge
- Deep space
- The world beyond our universe
And many other!
Since childhood, my favorite pastime was to watch informational and scientific-educational television programs about space. Later, in 2017, I began to prepare for the creation of a YouTube channel on this topic, creating material for future content in the form of numbered lists. But, unfortunately, the plans collapsed a year later. And now, in 2022, I finally did what I should have done more than 4 years ago!
I hope your time on my channel will not seem boring for you, and you will learn something new about what is above our heads. Happy viewing! :)

I'm 18 year old student, who is very interested in space topics since 5-6 years.
