22 Illinois projects receive time on Blue Waters


Jun 11, 2013

The University of Illinois at Urbana-Champaign has awarded access to the Blue Waters supercomputer—which is capable of performing quadrillions of calculations every second and of working with quadrillions of bytes of data—to 22 campus research teams from a wide range of disciplines. The computing and data capabilities of Blue Waters, which is operated by the National Center for Supercomputing Applications (NCSA), will assist researchers in their work on understanding DNA, developing biofuels, simulating climate, and more.

University of Illinois researchers help discover ‘dark galaxy’


Apr 14, 2016

Researchers have uncovered the existence of a dwarf "dark galaxy" lurking nearly 4 billion light-years away from Earth. The discovery was made when a team of researchers, including astronomers at the University of Illinois, using the Blue Waters supercomputer at the National Center for Supercomputing Applications (NCSA), noticed subtle distortions in the image of gravitational lens SDP.81. The discovery paves the way to spot many more such objects, which could help astronomers address important questions on the true nature of dark matter.

Newly Discovered Galaxy Is 4 Billion Light Years From Earth


Apr 18, 2016

This really is a galaxy far, far away. A hidden dwarf dark galaxy was discovered four billion light years away from Earth by astrophysicists at Stanford. The dwarf galaxy appears as a "tiny halo companion of a much larger galaxy," according to researchers. A new paper about the discovery will be published in the Astrophysical Journal. ... After capturing an image through gravitational lensing, researchers then used thousands of computers, including the supercomputer Blue Waters at the National Science Foundation, to determine the existence of the hidden dwarf galaxy.

The 21st: #BlackScienceMatters, & A New Galaxy Unveiled


Apr 18, 2016

A multimedia journalism project sheds a light the lack of representation of African-Americans in the sciences and engineering. We discussed what's being done about it. Also, we spoke with the researchers who discovered a new "dark galaxy" four billion light-years away.
