Gaia updates astronomers on nearby galactic collision

The latest Gaia data reveals how the Milky Way, Andromeda and Triangulum galaxies will collide in the future

A ghostly galaxy has been found just next door

The Gaia satellite has spotted an enormous ‘ghost’ galaxy lurking on the outskirts of the Milky Way

ESA’s Gaia found evidence in the night sky that points to the fact our galaxy did not form alone

Astronomers found hypervelocity stars racing toward the galactic centre, inferring they could have come from other galaxies

It has been narrowed down to four possible star systems from which ‘Oumuamua originated from

Prolonged data collect by ESA’s Gaia and Hipparcos satellites revealed the mass of exoplanet Beta Pictoris b

Using the power and synergy of two space telescopes, astronomers have made the most precise measurement to date of the universe’s expansion rate.

Astronomers propose that between eight and 10 billion years ago, a dwarf galaxy collided with the Milky Way and completely reshaped the galaxy

The results provide more valuable evidence in support of our current model of the universe

Using Gaia’s artificial brain, the paths of six hypervelocity stars have been deduced

The finding was made after recent analysis of data for millions of stars from the Gaia space mission
