Two planets collided in a distant solar system.

"While reviewing archived telescope observations from 2020, astronomer Anastasios (Andy) Tzanidakis noticed something unusual. A star that normally should behave in a predictable way was showing strange changes in brightness."(ScitechDaily, Astronomers Just Saw Two Planets Collide Around a Distant Star)

"The star, called Gaia20ehk, lies about 11,000 light-years from Earth near the constellation Pupis. It is classified as a stable “main sequence” star similar to our sun, meaning its light should remain steady over time. Instead, the star began flickering dramatically."(ScitechDaily, Astronomers Just Saw Two Planets Collide Around a Distant Star)

“The star’s light output was nice and flat, but starting in 2016 it had these three dips in brightness. And then, right around 2021, it went completely bonkers,” said Tzanidakis, a doctoral candidate in astronomy at the University of Washington. “I can’t emphasize enough that stars like our sun don’t do that. So when we saw this one, we were like ‘Hello, what’s going on here?’(ScitechDaily, Astronomers Just Saw Two Planets Collide Around a Distant Star)

"Star Gaia20ehk — seen here in the center of the orange crosshairs in the inset image — is roughly 11,000 light-years from Earth, near the constellation Pupis. Astronomers at the University of Washington conclude that observed flickering from the star is likely caused by a collision between two orbiting planets.

Nothing is as certain as uncertainty. This is a fact that we must realize. The star called Gaia20ehk lies 11000 light-years from our sun. That distant star is similar, and maybe the same age as the sun. Astronomers think that. They saw. Planets collide in that distant solar system. This is an interesting thing, because if that star system is as mature as our solar system, that raises an idea. That's the cosmic catastrophes. And even planetary-sized object collisions are possible even in mature solar systems. This is not the first case. These cosmic collisions destroy planets. The case of Formalhaut B could be a similar case, where the mature solar system faces catastrophe. Fortmalhaut b was almost confirmed as an exoplanet, but it suddenly disappeared. 

There is a planetary nebula at the point where Formalhaut b was, and that tells us. There was. Some kind of cosmic catastrophe. That destroyed the exoplanet. Its star, Formalhaut, is quite a young star, and its solar system is still in a chaotic period. The age of the star is about 440+-40 million years (myr). The age of the sun is about 4,6 billion years old. Things like rogue planets can destroy an entire solar system. And things like black holes, neutron stars, white dwarfs, or other stars. 

"Fomalhaut b as observed from 2004 to 2014. Previously thought to be an exoplanet, it is now known to be an expanding dust cloud." (Wikipedia, Fomalhaut b)

"The top graph shows brightness measurements (green and yellow dots) of star Gaia20ehk’s brightness in the visible light spectrum. Three small dips in brightness are apparent, followed by a more chaotic overall decline. The bottom graph shows measurements (pink, black and blue dots) of the star’s brightness in the infrared spectrum. The measurements show a sharp increase in infrared as the star’s visible brightness declines. In total, the observations suggest a collision between two planets in orbit around the star.

They can enter other solar systems, turning them into chaotic form. Those things are threats as well as mature and young solar systems. The thing that the Sun. It is maybe. Born near the center of our galaxy. There. Material whirls and denser materials are excellent for stellar formation. Proto stars pull material from around them. And that can cause turbulence in the material disk, or planetary nebula. This material flow. It can cause a situation. That environment that makes stellar formation possible. It is not so excellent for plantar formation. The radiation and particle flow near the galaxy, along with the denser stellar clusters and black holes, strip the material disks. From young stars. 

Causes discussions about the origins of planets, asteroids, and moons in our solar system. Our sun could trap some of those objects around it. The problem is how to separate objects. Those that were born in the dust disk around the sun from planets, moons, and asteroids whose origin is in the same nebula as our sun. Journey from the center of our galaxy is long, and our sun trapped lots of small and maybe large particles. But our sun also lost planets and other objects. 

If it had traveled past some other star. The thing. That pushed. The sun, away from the center of the Milky Way, is interesting. That eruption or gravitational effect required a lot of energy. So could the energy beam from the neutron star or black hole explain what made our sun travel to the location where it's now? The fact is that this kind of thing means that the Sun might lose many planets.  But there is a possibility that some planets in our solar system were rogue planets. One of the suspects is Uranus. But. In the young solar system, planets might change their places and trajectories. And that can open a new path. For searching for remnants of life from other planets and moons.
