Artist’s concept of NuSTAR in orbit. NuSTAR has a 33-foot (10-meter) mast that deploys after launch to separate the optics modules (right) from the detectors in the focal plane (left). Image credit: NASA/JPL-Caltech The planned launch of NASA’s Nuclear Spectro... More »
Astronomers have found celestial objects called quasars that bend and distort the light coming from galaxies behind them. The discovery may finally allow astronomers to determine the masses of galaxies that host quasars. “No one has done this before,” says G... More »
The Hubble Space Telescope’s sharp view was used to look for gravitational arcs and rings (indicated by arrows), which are produced when one galaxy acts as a lens to magnify and distort the appearance of another galaxy behind it. In this case, the foreground g... More »
In this image, robots designed and built by students for the 2011 FIRST Robotics competition are hanging as many plastic shapes on their scoring grid as possible in a two-minute-and-15-second timeframe. This year, the students are tasked with training their ro... More »
