SpaceX launches a NASA telescope that will observe black holes
The IXPE is the first satellite capable of measuring the polarization of X-rays that come from cosmic sources, such as black holes and neutron stars.
Scientists release biggest ever 3D map of the universe, lacks turn-by-turn navigation (video)
The stargazers at the Harvard-Smithsonian Center for Astrophysics have released a huge three-dimensional map of outer space, a core part of its six-year survey of the skies. Encompassing four billion light-years cubed, the researchers hope to use the map to retrace the movements of the universe through the last six billion years. Using the latest Sloan Digital Sky Survey (SDSS-III), the center says the data will help improve their estimates for the quantity of dark matter in space and the effect that dark energy has on the universe's expansion, "two of the greatest mysteries of our time" -- if you're an astrophysicist. Even if you're not, you'll still want to board the animated flight through over 400,000 charted galaxies -- it's embedded after the break.
Giant body of water found in space, black hole claims it was just hydrating
Is that an intergalactic wave pool, or just a hungry, hungry quasar? Turns out it's a bit of both -- well, not the wave pool bit, but it's watery. A NASA-funded peep into the farthest reaches of the cosmos has uncovered this "feeding black hole" 12 billion light years away. APM 08279+5255, as this compacted mass of inescapable doom is affectionately known, has been gorging on water vapor and spewing out energy. How much H2O exactly? It's only the "largest and farthest reservoir of water ever detected in the universe," and it weighs in at 140 trillion times the amount in our oceans. Located via the cooperation of two teams of astronomers and their star-gazing equipment -- the Z-Space instrument at California Institute of Technology's Submillimeter Observatory in Hawaii and the Plateau de Bure Interferometer in the French Alps -- this aqueous discovery proves the wet stuff is more universally omnipresent than we once thought. Also, surfing aliens, right?
String theory finds an elegant use for itself with qubit entanglement and black holes
Sure, trying to wrap your head around string theory -- a study in particle physics that's trying to rectify the perceived contradictions between general relativity and quantum mechanics -- can cause more cognitive pain than a colliding god particle. That hasn't stopped anyone from trying to validate its corollaries, and in the interim, researchers like Michael Duff of the Imperial College London. Mr. Duff realized a few years ago there existed some strong relations between formulas pertaining to both black holes (relativity) and four entagled qubits (quantum mechanics). So, in his words, "In a way, there's bad news and good news in our paper. The bad news is, we're not describing the theory of everything. The good news is, we're making a very exact statement which is either right or wrong. There's no in between." We're sure some science cliques are already gearing up to get their troll on.

Astronomers theorize what it's like when worlds (and black holes) collide
Tight binary solar systems are inhabited in science fiction -- remember the Star Wars world of Tatooine -- but humanity might find such planets inhospitable over the long term, and not just because of the heat. Using NASA's Spitzer telescope, scientists discovered clouds of dust around three such binary systems far too recent to come from the stars themselves, and theorize that as the stars attract one another over time and get closer and closer together, their respective orbiting planets may get closer as well, and crash into one another catastrophically. Meanwhile, when supermassive black holes dance in pairs, they can merge as one, and astrophysicists have recently simulated how such a joining might appear on our telescopes. According to a team of US and Canadian researchers, the pair may emit strong jets of electromagnetic radiation before they merge, which twist around one another and throw off gravitational waves that can help pinpoint the source. Speaking of sources, we've got plenty of those immediately below if you'd like to read more.
CERN rap video about the Large Hadron Collider creates a black hole of awesomeness
Been having a tough time figuring out just what CERN's Large Hadron Collider does? Worried that it will create a Möbius strip (a rip in the fabric of space where time becomes a loop)? Just love to jam? Watch this CERN-sponsored rap after the break, and have your universe totally destroyed. Er, but not for real.[Via Protein Feed]
PS3s used to simulate black hole collisions
It's like our favorite old-school commercial: "Mr. Owl, how many Playstation 3s does it take to simulate a collision between two black holes?" Apparently, the answer is 16. A group at the University of Massachusetts at Dartmouth hopes to use a cluster of 16 PS3s to run the simulation, specifically looking at the properties of the gravity waves emitted by the collision. The cluster -- nicknamed the PS3 Gravity Grid -- was built with a partial donation from Sony, who must like watching really big stuff collide as much as we do.Similar simulations have been run before (most notably by NASA), but this marks the first time the super-calculation has been performed using a game console. Like our colleagues as PS3 Fanboy, we admit that most of the technical jargon presented here is way over our heads. We're sure some of you will "get it," though, and not just resort to Tootsie Roll references.[Via PS3 Fanboy]
PS3 to simulate black hole collisions
How much do you value your brain? Hopefully enough to know not to fry it by trying to understand all the research, formulas, and theories behind the project to use 16 PS3's to simulate a collision of two black holes. Headed in part by Guarav Khanna at UMassD, the project ... well ... it's hard to explain. Perhaps its our lack of scientific knowledge. Khanna calls the setup the "gravity grid" and have installed Linux on the PS3's to more accurately compute the "ripples" caused by gravitational waves from black holes.It's complicated stuff, but we're impressed to see yet another use for the PS3 outside of the general gaming audience. If you want to learn more about the project, knock yourself out. We'll just sit back and nod like we understand the implications of this research. It sounds really cool, though![Via reghardware]
