Discover the cosmosEach day a different image or photograph of our fascinating universe is featured, along with a brief explanation written by a professional astronomer.
Explanation:There are more thanhalf a million galaxiesin the central panel of thisimagefrom theNSF-DOE Vera C.
Rubin ObservatoryinChile.
This is theCOSMOS field, a patch of sky several times larger than thefull moon, first observed byHubble.
It has also been observed byWebband other telescopes because it contains comparatively few brightstarsfrom our own galaxy, offering a relatively unimpeded view of other galaxies outside the Milky Way.
The outer panels, numbered 1-10, showzoomed-in viewsof the corresponding small regions highlighted in the central panel.
The variety of galaxy shapes and sizes isastonishing.
Some of them are so far away that their light has traveled forbillions of yearsbefore reaching Earth.
Rubin will come backevery couple of daysto the COSMOS field as part of its ten-year Legacy Survey of Space and Time.
It will allow a dynamic view of the COSMOS field and how the sky changes over time.
