Gaia's highly accurate monitoring of stars' positions is a key tool in asteroid tracking. But when Gaia spots a faint light source moving so quickly across the spacecraft's field of view that the object is spotted in only one image before vanishing, this indicates a body much closer to Earth.Ĭhecking these bodies against databases of known solar system bodies allows researchers to determine if the objects are previously discovered asteroids, and this cross-checking method often turns up new discoveries. Because these stars are so distant, the movements the spacecraft sees are minuscule. This method allows Gaia to target billions of stars and observe how their positions change over time. The Gaia mission differs from the Hubble Space Telescope and the James Webb Space Telescope in that, rather than selecting an object or group of objects and studying them intensely, Gaia charts the entire sky, making repeated observations. The Gaia data also show that while the flying-saucer-shaped satellite has made a splash delivering data on distant stars and exoplanets within the Milky Way, Gaia is more than capable of influencing science much closer to home. This means that Gaia data could help astronomers better understand the solar system and its evolution. It’s five year mission is to construct the largest and most precise 3D map of our galaxy, the Milky Way, this will contain over 1 billion astronomical objects, mainly stars but also planets, comets, asteroids and quasars among others.Currently, astronomers have the spectra of just a few thousand asteroids, and scientists at the University of Helsinki in Finland predict that Gaia could increase this number tenfold. Gaia is a European Space Agency (ESA) satellite. Click on the alerts to find out details about the specific objects, such as when they were discovered and information about them. ![]() Look around the sky and spot the latest supernovae and variable stars that have been discovered by the European Space Agency mission, Gaia. ĭiscover and explore the latest alerts from the Gaia mission in Virtual Reality. You can download the app via iTunes or Google Play Store. More live contents will become available in the future. This includes the satellite status, current distance from Earth, transits observed and processed among others. Live information about the mission progress and access to the latest Gaia related news are available on the mission section. Updates on mission operations in real time. Additional in-depth information can be accessed by swiping horizontally. Vertical swipes change screens that describe concepts in a simple straightforward language. Topics cover all aspects of the mission, from stellar parallax or exoplanets detection to focal plane operations and launch vehicle stages. The app features an interactive 3D model of the satellite, multimedia content and interactive elements designed to explain complex concepts. The application is currently available for iOS and Android, in English, Spanish and Catalan. The application is designed to keep users engaged during the whole mission and build interest on the mission achievements while stimulating enthusiasm for astronomy. Combined, the two platforms capture 96% global market share. ![]() All aspects of the mission are covered, from technical issues to the science behind it. The Gaia Mission app is an interactive application for mobile devices designed to discover the details of the Gaia mission. The main goal of the Gaia mission is to make the largest, most precise three-dimensional map of our Galaxy by surveying an unprecedented one per cent of its population of 100 billion stars.ĭelivering interesting and scientifically accurate information to the general public is a challenge. The Gaia mission App allows you to discover the details of Gaia, the cornerstone astrometry mission of the European Space Agency (ESA) to survey our Galaxy. Here is shown a set of 3 mobile applications that are closely related to the Gaia mission of the ESA.
