Gaia Data Release 3: Exploring our Multi-Dimensional Milky Way

Since its launch in 2013 ESA’s Gaia observatory has been mapping our galaxy from Lagrange point 2, creating the most accurate and complete multi-dimensional map of the Milky Way. By now two full sets of data have been released, the first set in 2016 and a second one in 2018. These data releases contained stellar […]

NASA Supports Event Horizon Telescope in Studying Milky Way’s Black Hole

The black hole at the center of our galaxy is the subject of a groundbreaking new image from the Event Horizon Telescope collaboration. As the Event Horizon Telescope collected data for its remarkable new image of the Milky Way’s supermassive black hole, a legion of other telescopes including three NASA X-ray observatories in space was also […]

Gaia finds parts of the Milky Way much older than expected

Gaia finds parts of the Milky Way much older than expected

Using data from ESA’s Gaia mission, astronomers have shown that a part of the Milky Way known as the ‘thick disc’ began forming 13 billion years ago, around 2 billion years earlier than expected, and just 0.8 billion years after the Big Bang. This surprising result comes from an analysis performed by Maosheng Xiang and Hans-Walter […]

Gaia reveals a new member of the Milky Way family

This image shows the Milky Way as seen by Gaia. The squares represent the location of globular clusters, the triangles the location of satellite galaxies, and the small dots are stellar streams. The dots and squares in purple are objects brought into the Milky Way by the Pontus merging galaxy. Adapted from the ESA’s Science […]
