What Kind of Object Can Survive a Close Encounter With a Monster Black Hole?
In or around May 2014, a truly remarkable thing happened: An object, dubbed G2, survived a very close encounter with a very large black hole. The black hole in this case is the supermassive one in the center of our own galaxy, the Milky Way. Our best estimate...

Astronomers reveal supermassive black hole's intense magnetic field
Astronomers from Chalmers University of Technology have used the giant telescope Alma to reveal an extremely powerful magnetic field very close to a supermassive black hole in a distant galaxy. The results appear in the 17 April 2015 issue of the journal Science.

Cold cosmic mystery solved: Largest known structure in the universe leaves its imprint on CMB radiation
In 2004, astronomers examining a map of the radiation leftover from the Big Bang (the cosmic microwave background, or CMB) discovered the Cold Spot, a larger-than-expected unusually cold area of the sky. The physics surrounding the Big Bang theory predicts warmer and cooler spots of various sizes in ...

Giant cosmic tsunami wakes up comatose galaxies
Galaxies are often found in clusters, which contain many 'red and dead' members that stopped forming stars in the distant past. Now an international team of astronomers have discovered that these comatose galaxies can sometimes come back to life. If clusters of galaxies merge, a huge shock wave can drive the birth of a new generation of stars -- the sleeping galaxies get a new lease of life.

NASA May Have Accidentally Discovered Faster-Than-Light Travel
The idea of faster-than-light travel has been one of the greatest staples in science fiction for as long as the genre has been around. The idea of traveling to other planets with terrestrial technology seemed impossible for a long time - but, with the power of faster-than-light travel, moving from planet to planet would be almost instantaneous. Who wouldn't want to go zipping through the galaxy, discovering and visiting all sorts of different planets?

Magnetar near supermassive black hole delivers surprises
In 2013, astronomers announced they had discovered a magnetar exceptionally close to the supermassive black hole at the center of the Milky Way using a suite of space-borne telescopes including NASA's Chandra X-ray Observatory. A new study uses long-term monitoring observations to reveal that the amount of X-rays from SGR 1745-2900 is dropping more slowly than other previously observed magnetars, and its surface is hotter than expected.

The Dark Side of Star Clusters
Observations with ESO’s Very Large Telescope in Chile have discovered a new class of “dark” globular star clusters around the giant galaxy Centaurus A. These mysterious objects look similar to normal clusters, but contain much more mass and may either harbour unexpected amounts of dark matter, or contain massive black holes — neither of which was expected nor is understood.

Astronomers see a supernova colliding with its companion star
Type Ia supernovae, one of the most dazzling phenomena in the universe, are produced when small dense stars called white dwarfs explode with ferocious intensity. At their peak, these supernovae can outshine an entire galaxy. Although thousands of supernovae of this kind were found in the last decades, ...
