A recent study of two far off dwarf galaxies challenges the standard cosmological model by presenting contrary observations of dark energy. Rather than dark matter being concentrated at the center of the Fornax and Sculptor galaxies, as the standard model would predict, researchers at the Harvard-Smithsonian Center for Astrophysics found that it was distributed equally among the millions of stars they observed. "After completing this study, we know less about dark matter than we did before," said the lead author. What's the Big Idea? With galaxies like our Milky Way rotating through space at incredible velocities, why don't their stars go flying off in all directions? NASA's Kepler Mission. Astrophile: The sticky star cluster that's mostly black hole - space - 21 October 2011.
Astrophile is our weekly column covering curious cosmic objects, from within the solar system to the furthest reaches of the multiverse Object type: Star clusterLocation: Stone's throw from Milky Way's supermassive central black hole At the centre of the Milky Way, a cluster of three stars perches precariously on the edge of oblivion, a mere stone's throw in cosmic terms from the supermassive black hole at the galaxy's core.
Like a delicate spiderweb that somehow survives a hurricane, the group's continued existence seems impossible in the face of the black hole's extreme gravity, which should rip the cluster apart. Now there's a fresh explanation: a dense swarm of small black holes within the cluster that help glue it together. The result would be an object that is mostly black hole – with a few stars sprinkled in. The cluster in question, called IRS 13E, first showed up in the 1980s as a bright spot in infrared observations that pierced the dust veil around our galaxy's core. Lytro's new light field camera lets you focus after you take a picture. Imaging scientist Ren Ng's years of research into capturing "light fields" using increasingly high-resolution digital imaging sensors have finally come to fruition.
Ng's company, Lytro, unveiled its first consumer product on Wednesday—a digital camera capable of capturing "living images" that can be infinitely refocused after capture. While the new camera is designed to change the way we capture and share snapshots, the technology has the potential to radically alter how all photographs are made. The new Lytro camera is a small rectangular tube of aluminum, with an f/2 lens on one end and a small 2" touchscreen on the other.
The only controls are a power button, shutter button, and a slider to control the 8x zoom range of its lens. There are no controls for aperture, shutter speed, or focus—because the Lytro doesn't need them. The Lytro is probably the closest thing to "point-and-shoot" photography that has ever existed in the digital era. Capturing light fields Future of photography.

VLT ontdekt grootste gele hyperreuzenster Gepubliceerd op 12 maart 2014 Met ESO’s Very Large Telescope Interferometer is een ster opgespoord die de grootste gele ster blijkt te zijn die we kennen. Zij behoort zelfs tot de tien grootste sterren die tot nu toe zijn ontdekt. De hyperreus is meer dan 1300 keer zo groot als de zon en vormt, samen met een andere ster die zo dichtbij staat dat de twee elkaar raken, een dubbelstersysteem. Waarnemingen die zich over meer dan zestig jaar uitstrekken, sommige door amateur-waarnemers, geven aan dat dit zeldzame en opmerkelijke object heel snel verandert en tijdens een zeer kortstondige levensfase is betrapt. Dr. Alex Lobel van de KSB behoort tot het team dat deze ster bestudeerde. Meer info hierover op de ESO webpagina's.
