Milky Way Galaxy
Data indicate Milky Way smash up 10 billion years ago
Cataclysmic collision re-shaped Milky Way in distant past
Gaia data pins down 1.7 billion suns in most detailed star catalogue ever
Astronomers collect spectra in search for Sun’s lost siblings
Milky Way no longer ‘little brother’ to Andromeda
At the core, a sea of suns shines like a ‘jewel box full of stars’
The Hubble Space Telescope captures a deep view of stars in the Milky Way’s central bulge, helping astronomers understand a dynamic environment where stars rich in heavier elements orbit the core faster than older stars that are deficient in such elements. The image is part of two on-going surveys to learn more about the galaxy’s structure and evolution.
Galactic merger exposes supermassive black hole
Astronomers using the super-sharp radio vision of the National Science Foundation’s Very Long Baseline Array (VLBA) have found the shredded remains of a galaxy that passed through a larger galaxy, leaving only the smaller galaxy’s nearly-naked supermassive black hole to emerge and speed away at more than 2,000 miles per second.
