(NASA)  Hubble Shows Farthest Lensing Galaxy Yields Clues to Early Universe
Astronomers using NASA’s Hubble Space Telescope have unexpectedly discovered the most distant galaxy that acts as a cosmic magnifying glass. Seen here as it looked 9.6 billion years ago, this monster elliptical galaxy breaks the previous record-holder by 200 million years.
(…) The object behind the cosmic lens is a tiny spiral galaxy undergoing a rapid burst of star formation. Its light has taken 10.7 billion years to arrive here and seeing this chance alignment at such a great distance from Earth is a rare find. Locating more of these distant lensing galaxies will offer insight into how young galaxies in the early universe build themselves up into the massive dark-matter-dominated galaxies of today. Dark matter cannot be seen, but it accounts for the bulk of the universe’s matter.

(Space.com) Galaxy’s Huge Black Hole Puts on Spectacular Fireworks Show

The supermassive black hole at the center of a far-off galaxy is putting on a fireworks display of cosmic proportions.

Scientists captured the brilliant display in new images and a video tour of the spiral galaxy Messier 106 (also called NGC 4258). An amazing composite picture was created by combining data from three NASA telescopes and a National Science Foundation (NSF) telescope trained on Messier 106, which is about 23 million light-years away.

(Space.com)  Going Nova: Star Explosions Unleash Gamma-Ray Blasts

Gamma-rays, the most powerful form of light, may erupt from star explosions called novas surprisingly often, but the way these gamma-rays form remains a mystery, scientists say.

High-energy gamma-rays are typically associated with supernovas, the explosive deaths of stars. These explosions are bright enough to momentarily outshine their entire galaxies.

(….) In 2010, astronomers detected high-energy gamma-rays from the nova V407 Cyg about 8,800 light-years away in the constellation Cygnus the Swan. This eruption gave off the equivalent of about 1,000 times the energy emitted by the sun every year.

Quote reblogged from think locally act globally with 99 notes

It’s impossible for me to even imagine people saying these people were injured hours or days before the event occurred. Any doctor who saw them, treated them, could tell you their injuries had occurred just then. We took shrapnel out of a baby’s back. Do people really think a mother sat around with her baby’s back covered in shrapnel, waiting to take him to a hospital so that she could blame Israel for his death?
