Intense Flash from Milky Way’s Black Hole Illuminated Gas Far Outside of Our Galaxy
Not long ago, the center of our galaxy exploded. Our primitive ancestors, already afoot in Africa, probably saw the resulting flare. Now Hubble detects that flash’s signature in a huge tail of gas orbiting the galaxy some 200,000 light-years away.
Hubble Probes Alien Comet’s Chemical Makeup
Zooming through space, the first bonafide interstellar comet discovered passing through our solar system is yielding chemical clues to its origin. An abundance of carbon monoxide contained in comet Borisov suggests it was born around a cool red dwarf star.
Quasar Tsunamis Rip Across Galaxies
A team of astronomers using Hubble have found the most energetic outflows ever witnessed in the universe. These outflows emanate from quasars and tear across interstellar space like tsunamis, wreaking havoc on the galaxies in which the quasars live.
