RX J1140.1+0307

The beautiful spiral galaxy visible in the center of the image is known as RX J1140.1+0307, a galaxy in the Virgo constellation imaged by the NASA/ESA Hubble Space Telescope, and it presents an interesting puzzle.

Struggle to Escape Distant Galaxies Creates Giant Halos of Scattered Photons

Struggle to Escape Distant Galaxies Creates Giant Halos of Scattered Photons

Astronomers led by David Sobral and Jorryt Matthee, of the Universities of Lancaster in the UK and Leiden in the Netherlands have discovered giant halos around early Milky Way type galaxies, made of photons (elementary particles of light) that have struggled to escape them.

This delicate smudge in deep space is far more turbulent than it first appears.


Our Galaxy's Black Hole is Spewing Out Planet-size Spitballs

Our Galaxy's Black Hole is Spewing Out Planet-size Spitballs

Every few thousand years, an unlucky star wanders too close to the black hole at the center of the Milky Way. The black hole's powerful gravity rips the star apart, sending a long streamer of gas whipping outward.


Nearby Black Holes Lurk Behind Gas and Dust

Nearby Black Holes Lurk Behind Gas and Dust

Monster black holes sometimes lurk behind gas and dust, hiding from the gaze of most telescopes.
