According to new research, Antlia 2’s current position is consistent with a collision with the Milky Way hundreds of millions of years ago that could have produced the perturbations we see today. The paper has been submitted for publication and is undergoing peer review. Antlia 2 was a bit of a surprise when it showed up Read more about We Have Detected Signs of Our Milky Way Colliding With Another Galaxy[…]
The first batch of satellites were launched from Cape Canaveral, Florida, and deployed to orbit by a Falcon 9 rocket on May 23. Each contains a single solar array, which both captures and bounces sunlight off the satellites and, as a result, can sometimes be seen from Earth. On May 25, as the drifting luminescent Read more about SpaceX Starlink satellites dazzle but pose big questions for astronomers – Musk thought things out well again, not.[…]
A recent parachute test of the SpaceX Crew Dragon capsule “was not satisfactory,” a NASA official said during a House subcommittee hearing yesterday.
