A Black Hole doesn’t die — It does something a lot weirder

Chandra Observatory — If a particle and its antiparticle pop into being on the event horizon, one gets sucked in. The other gets away. If the antiparticle gets sucked into the black hole, and the particle breaks free, the particle no longer has a chance to annihilate. It is now real, and not virtual. Its presence and energy count in the universe. And real radiation leaking from a black hole means that the black hole itself is slowly shrinking. (Credit: Chandra Observatory, NASA, Inglis-Arkell)

China eyes first space station by around 2022

Evidence of forming planet discovered 335 light-years from Earth

Is the universe a stable quantum system?

If our understanding is correct, then the universe as a whole could be in a locally stable configuration, but it could also jump to a lower energy state through a process of quantum tunneling. If that happened, the universe would collapse and we'd all go bye bye. So to our best understanding, it is possible for the universe to collapse.

Newly discovered ‘Tetraquark’ fuels quantum feud

Quarks have one of three “color charges,” which are analogous to the primary colors red, green and blue. Just as an atom strikes a balance between positive and negative electrical charges, particles made of quarks balance colors to reach a neutral state. In the color analogy, that means combining colors to make white. (Credit: Quanta Magazine)

Alcohol clouds in space

(Credit: HUbble) — There is a giant cloud of alcohol in outer space. It’s in a region known as W3(OH), only about 6500 light years away. Unfortunately it is methyl alcohol (commonly known as wood alcohol, though this stuff is not derived from wood), so it isn’t suitable for drinking. There is some ethyl alcohol (the drinkable kind).(Credit: Hubble)

Why is the Space Station launching satellites on its own?

Two tiny satellites escaping on their own doesn’t sound too bad … except it’s not the first time this has happened. On August 23rd, NASA reports that two other CubeSats set themselves free. OK, 4 out of 100 doesn’t sound too bad either … except only 12 have been launched so far, which means a quarter of the CubeSats un-tethered themselves. (Credit: NASA)

Black hole thermodynamics

Simulation of a black hole merger. (Credit: NASA/Chandra) — Classical black holes have “no hair”, meaning that they are simply described by their mass, charge and rotation. Because of this, you could toss an object (with a great deal of entropy) into a black hole, and the entropy would simply go away. (Credit: NASA/Chandra, B. Koberlein )

Milky Way galaxy is just half as massive as Andromeda

Andromeda is twice as massive as the Milky Way. Scientists say that Andromeda has twice the mass, made of dark matter, than the Milky Way.

General Relativity – Embedding light at the heart of cosmology

Einstein was the first person to propose that ‘empty space’, which does not contain matter or radiation, is not actually empty and in fact has a residual energy. This empty space is also capable of creating more space from itself. (Credit: benmoat/Shutterstock)

Europe’s Rosetta probe reaches climax of its comet-chasing mission

The Rosetta spacecraft is scheduled to rendezvous with Comet 67P/Churyumov-Gerasimenko on Wednesday. If all goes according to plan, Rosetta will become the first probe ever to orbit a comet — and, in November, the first to drop a lander onto the surface of one of these icy wanderers. (Credit: ESA)

Science and spacewalks on Space Station

This might look like a routine scientific experiment, but you’re actually looking at European Space Agency astronaut Alexander Gerst as he sets fire to samples of various solids aboard the International Space Station to see how they burn. This man truly has a wonderful job. (Credit: ESA)
