MilkyWay at Home

Hey Volunteers,

The server is currently down for maintenance. It will probably be down at least through the rest of the day. We hope to be back to normal service in a day or two.

Thanks for the patience!

With the help of tens of thousands of volunteers from around the world, we've been able to reconstruct a dwarf galaxy that left a stream of stars in the night sky! This object was ripped apart billions of years ago by the Milky Way.

We have measured the original shape and mass of the dwarf galaxy that was ripped apart to make the Orphan-Chenab Stream!

Professor Heidi Jo Newberg has made a video explaining the Orphan-Chenab progenitor result:

The MilkyWay@home website is currently down. We believe this is an RPI network issue, not a problem with MilkyWay@home. We will update you as soon as the problem is resolved or we know more.

Thanks for all the help and your continued patience!

MilkyWay@home is expected to remain down for the next couple days. We do not have a timeline on when the RPI network issues will be resolved. We will let you all know as soon as we find out more about the situation. Thank you again for your patience!
