ESA Euronews: Gaia’s revolution in astronomy

Astronomy is undergoing a revolution with the release of precision data on 1.7 billion stars in our galaxy from the Gaia space telescope. We head to the historic Observatory of Paris and ESA’s ESTEC base in the Netherlands to find out more.

It’s fair to say that science has been waiting for centuries, or even millennia for such a detailed survey of the Milky Way, and right now star-gazers are swamped with fresh, high-quality data that they can use to answer every question about the galaxy they ever wanted to ask.

Gaia second data release

The second data release of ESA’s Gaia mission has produced an extraordinary catalogue of over one and a half billion stars in our galaxy. Based on observations between July 2014 to May 2016, it includes the most accurate information yet on the positions, brightness, distance, motion, colour and temperature of stars in the Milky Way as well as information on asteroids and quasars.

Waiting for Gaia

On 25 April 2018, ESA’s Gaia mission will publish its much awaited second data release, including high-precision measurements of nearly 1.7 billion stars in our Galaxy.

Scientists who have been working on creating and validating the data contained in the catalogue tell us why they are waiting for this extraordinary release.

Featured in the video: Antonella Vallenari (INAF, Astronomical Observatory of Padua), Anthony Brown (Leiden University), Timo Prusti (European Space Agency), Annie Robin (Institut UTINAM, OSU THETA Franche-Comté-Bourgogne), Laurent Eyer (University of Geneva) and Federica Spoto (IMCCE, Observatory of Paris).

A media briefing on the second Gaia data release will be held at the ILA Berlin Air and Space Show in Germany on 25 April 11:00-12:15 CEST. Watch the webstream at www.esa.int/live

Chasing a stellar flash

Last year, ESA’s Gaia mission helped astronomers make unique observations of Neptune’s large moon Triton as it passed in front of a distant star. This is a preview of the superb quality and versatility of the Gaia data that will be released in April.
