About Space Warps - ESA Euclid
Imagine a galaxy, behind another galaxy. Think you won't see it? Think again.
Massive galaxies warp space-time, bending light rays so that we can see around them. These gravitational lenses are very rare and hard to find, but, in our early test projects with Euclid data, you have already helped us find hundreds of new candidates.
ESA and the Euclid Consortium have allowed us to extend our initial lens searches and share some of the newest data from the Euclid Space Telescope with you. These data will be publicly available in the autumn of this year as Euclid’s first major Data Release (DR1) covering a mammoth 1900 square degrees, roughly 9500 times the area of the full moon on the night sky!
In this new search, a range of machine learning strong lens finders, that were fine tuned with the results from the initial Euclid strong lens searches you participated in, classified a whopping 72 million galaxies from the DR1 data. We would very much like you to join us in inspecting the hundreds of thousands of high scoring lens candidates in these never before seen Euclid images. Many previously unknown strong lenses will be hiding in this exquisite high-quality imaged. We can expect this area to reveal more than ten thousand new lenses, more than 4 times larger than all of the strong lenses we have discovered in almost 50 years since their discovery!
For more information about this project and lensing in general, please see the About pages, the ESA webstory and the Space Warps blog.
Join us as we begin this exciting new journey to find rare strongly lensed gravitational lenses in this previously unseen Euclid data!!
Request a Space Warps Contribution Certificate with your classification info, or you can download your own from your Zooniverse home page. If you have already requested a Space Warps ESA Euclid certificate from one of the previous runs, you don't need to submit again.
