Our Solar System is Rare –“Big Question is What Makes It So Special That It Harbors Life?”

“Something is the cause of the fact that there aren’t a huge amount of UFOs out there,” says Uffe Gråe Jørgensen, head of Astrophysics & Planetary Science group at the Niels Bohr Institute, about the huge difference between being one of the 10 billion Earth-like planets in the habitable zone, and being habitable or having developed a technological civilization.

“The collision with Kraken must have been the most significant merger the Milky Way ever experienced,” said astrophysicist Diederik Kruijssen at the Center for Astronomy at the University of Heidelberg (ZAH), about artificial intelligence analysis of ancient globular clusters almost as old as the universe itself orbiting the Milky Way that revealed a stunning picture of successive mergers with neighboring galaxies creating what is, in effect, a galactic “family tree”.

“The Unexpected Galaxy” –Milky Way ‘Twin’ Unveiled Near Dawn of the Universe

 

"The Unexpected Galaxy" --Milky Way 'Twin' Unveiled Near Dawn of the Universe

 

“Philosophically, the universe has really never made things in ones,” says astrophysicist Neil deGrasse Tyson. Astronomers, underscoring Tyson’s observation, unveiled a surprisingly unchaotic, extremely distant, and therefore very young galaxy that looks much like our Milky Way Galaxy minus the spiral arms but with a rotating disc and a bulge, with a large group of stars packed tightly around the galactic center. This is the first time a bulge has been seen this early in the history of the Universe.

"Someone is Looking Back at Us" --Three-Hundred-Million Earth-Like Worlds of the Milky Way

 

“One in 200 stars has habitable Earth-like planets surrounding it – in the galaxy, half a billion stars have Earth-like planets going around them – that’s huge, half a billion. So when we look at the night sky, it makes sense that someone is looking back at us,” says physicist, Michio Kaku, author of The Future of Humanity.

“Umbrellas of Stars” –A Dwarf Galaxy Crashed Broadside Into Milky Way 2.7 Billion Years Ago

 

Nyx --"A Vast Alien Star Stream Observed Near the Sun"

 

In 2018, an international team of astronomers proposed that around 8 billion to 10 billion years ago an unknown massive dwarf galaxy dubbed the “Sausage” –with a total mass in gas, stars and dark matter more than 10 billion times our sun– crashed head-on into our Milky Way galaxy, ripping the dwarf to shreds, leaving its stars moving in long, narrow needle-like radial orbits. This defining event in the early history of the Milky Way reshaped the structure of our galaxy into its warped, twisted shape shown above, with the Sausage debris scattered around the inner parts of the Milky Way, creating the ‘bulge’ at the galaxy’s center and the surrounding ‘stellar halo.’
