The Celeste Project: Celeste is a collaboration between MIT, UC Berkeley, Harvard, Julia Computing, Intel, and NERSC (the DoE's supercomputing center). They recently managed to calculate the first comprehensive statistical catalog of astronomical objects in the visible universe. That's over 188 million stars and galaxies!
Using some nifty new methods they developed, the collaboration managed to complete the entire calculation in only 15 minutes. We believe this system will massively accelerate astronomy research, especially once scientists start receiving higher-resolution images from new telescopes like the LSST and the James Webb Space Telescope.
