News

Epic campaign confirms relativity near supermassive black hole

26 July 2018 Astronomy Now

Astronomers tracking a star passing close to the supermassive black hole at the heart of the Milky Way have detected relativistic gravitational redshift in light reaching Earth.

Hint of relativity effects in stars orbiting centre of galaxy

10 August 2017 Astronomy Now

A new analysis of data from ESO’s Very Large Telescope and other telescopes suggests that the orbits of stars around the supermassive black hole at the centre of the Milky Way may show the subtle effects predicted by Einstein’s general theory of relativity.

Newly discovered stars shed light on Milky Way’s formation

23 November 2016 Astronomy Now

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

23 June 2016 Astronomy Now

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

8 June 2016 Astronomy Now

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.

News

Radio telescopes could spot supersonic stars hidden in the galactic centre

22 September 2015 Astronomy Now

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.
