Fly between Gaia stars @ESAScienceHub

Uploaded April 2018 | Updated September 2026, 55 minutes ago

A virtual flight that takes the viewer from the Solar System through our Milky Way Galaxy. The journey starts by looking back at the Sun, moving away and travelling between the stars.

The animation is based on data from the second release of ESA’s Gaia satellite, specifically on the 3D position of nearly 97 million stars, the majority of which have the most accurate parallax measurements in the dataset. Accurate parallaxes can be used to directly estimate distances to individual stars.

The depths of space, Euclid, LISA, and the mysterious effects of gravity – Expedition Sound 4

$An extragalactic star-forming region This video shows a view of M33, also known as the Triangulum galaxy, taken by ESAs Gaia satellite, zooming in to show the star-forming region NGC 604, first as viewed by Gaia and then by the NASA/ESA Hubble Space Telescope. Located some 2.4 million light-years away, M33 is one of our neighbouring galaxies and is part of the Local Group, the assembly of galaxies that includes our Milky Way and the Andromeda galaxy. A spiral galaxy with less than one tenth the mass of the Milky Way or Andromeda, M33 is the third largest member of the Local Group and is thought to be a satellite galaxy of Andromeda. Gaias detections correspond to about 40 000 of the galaxys brightest stars, a small fraction of the total stellar population of M33, which amounts to roughly 40 billion stars. A red square indicates the star-forming region NGC 604, which is located to the top left of M33s centre in this view. The video zooms in to show Gaias view of NGC 604, and finally fades to reveal Hubbles image The comparison between the Gaia and Hubble views shows that Gaia has detected about 150 individual stars in the NGC 604 region, which spans only about 0.55 square arcminutes in the sky. This number might not sound big in absolute terms, but it is impressive when considering that the observed field is about 2000 times smaller than the area covered by the full Moon in the sky, revealing that Gaia is able to detect a significant number of extragalactic stars. This is even more remarkable given that Gaias observed stars are automatic detections obtained by the satellites onboard computing system while scanning over the region, whereas the stars detected in astronomical images, such as those from Hubble, are the result of dedicated observations obtained by pointing at specific regions on the sky, which are later analysed by scientists.
