Newly discovered stars shed light on Milky Way’s formation
An astronomer from Liverpool John Moores University has discovered a new family of stars in the core of the Milky Way which provides new insights into the early stages of the galaxy’s formation. The discovery has shed new light on the origins of globular clusters formed at the beginning of the Milky Way’s history.
Successful first observations of galactic centre with GRAVITY instrument
A European team of astronomers have used the new GRAVITY instrument at ESO’s Very Large Telescope to obtain exciting observations of the centre of the Milky Way by combining light from all four of the 8.2-metre Unit Telescopes for the first time. These results provide a taste of the groundbreaking science that GRAVITY will produce as it tests Einstein’s general relativity.
Computer simulations shed light on Milky Way’s missing red giants
New computer simulations from the Georgia Institute of Technology provide a conclusive test for a hypothesis of why the centre of the Milky Way appears to be filled with young stars but has very few old ones. According to the theory, the remnants of older, red giant stars are still there — they just aren’t bright enough to be detected with telescopes.
Radio telescopes could spot supersonic stars hidden in the galactic centre
The centre of our Milky Way galaxy is a mysterious place. Not only is it thousands of light-years away, it’s also cloaked in so much dust that most stars within are rendered invisible. Harvard researchers are proposing a new way to clear the fog and spot stars hiding there. They suggest looking for radio waves coming from supersonic stars.
