Hubble Studies Gamma-Ray Burst With Highest Energy Ever Seen

11.20.2019
NASA’s Hubble Space Telescope has given astronomers a peek at the location of the most energetic outburst ever seen in the universe — a blast of gamma-rays a trillion times more powerful than visible light. That’s because in a few seconds the gamma-ray burst (GRB) emitted more energy than the Sun will provide over its entire 10-billion year life.

NASA’s TESS Mission Spots Its 1st Star-shredding Black Hole

09.26.2019
​For the first time, NASA’s planet-hunting Transiting Exoplanet Survey Satellite (TESS) watched a black hole tear apart a star in a cataclysmic phenomenon called a tidal disruption event. Follow-up observations from other instruments have produced the most detailed look yet at the early moments of one of these star-destroying occurrences.

Moon Glows Brighter Than Sun in Images From NASA's Fermi

08.15.2019
If our eyes could see gamma rays, the Moon would appear brighter than the Sun! That's how NASA's Fermi Gamma-ray Space Telescope has seen our neighbor in space for the past decade. These gamma-ray observations are a reminder that astronauts on the Moon will require protection from the same cosmic rays that produce this high-energy gamma radiation.
