BOINC

Launched in December 2021 on an Ariane 5 rocket from Europe’s Spaceport in French Guiana, is designed and built to offer scientists the capabilities needed to push the frontiers of knowledge in many areas of astronomy. This includes research on our own Solar System, the formation of stars and planets (including planets outside our Solar System — exoplanets), and on how galaxies are formed and evolve, in ways never before possible.

Our latest Picture of the Week captures a not-so-close encounter. The twin galaxies NGC 4496A and NGC 4496B dominate the frame in this image from the NASA/ESA Hubble Space Telescope. Both galaxies lie in the constellation Virgo, but despite appearing side-by-side in this image they are at vastly different distances from both Earth and one another. NGC 4496A is 47 million light-years from Earth while NGC 4496B is 212 million light-years away. The enormous distances between the two galaxies mean that the two cannot interact, and they only appear to overlap owing to a chance alignment.
