Gaia telescope mission to find more than 500 thousand new stars ever detected: Okezone techno

MISSION exploration carried out with Gaia Telescope managed to discover more than 500,000 previously unknown stars. Some even call it a star mine.

As reported by Space on Friday (10/13/2023), this discovery contained more than half a million new faint stars, more than 380 new gravitationally lensed quasars, and more than 150,000 asteroids located in the solar system.

This brand new star map will allow scientists to continue digging deeper into cosmic history. This new version will also fill some important gaps in the map as it takes shape.

According to Gaia’s operator, the European Space Agency (ESA), this new data provides exciting and unexpected scientific discoveries and discoveries that go far beyond what they were originally designed for.

This new round of research builds on Gaia’s third Data Release (DR3) released in June 2022. While complete, DR3 contains gaps in the sky that have not yet been mapped by space telescopes.

A particular example of this is globular clusters, which are some of the oldest objects in the universe with densely packed cores of bright stars that can overwhelm telescopes to study them.

“In Omega Centauri we discovered more than half a million new stars that Gaia had never seen before, from just one cluster!” said study lead author and Gaia collaboration member Katja Weingrill.

Gaia itself observes Omega Centauri with a special mode that allows it to see a wider band of sky around the globular cluster’s core whenever it is visible. Gaia doesn’t just focus on individual stars in clusters.

While this new data has helped fill in some unexplored areas in Gaia’s 3D map of the Milky Way, it is interesting to scientists because it helps better model the Omega Centauri globular cluster.

“Our data allows us to detect stars that are too close together to be accurately measured in the normal Gaia pipeline,” added study co-author and Gaia Collaboration member Alexei Mints.

“With this new data, we can study the structure of the cluster, how its component stars are distributed, how they move and more, creating a complete large-scale map of Omega Centauri,” he concluded.
