NASA's WISE Spacecraft Discovers Most Luminous Galaxy in Universe

A remote galaxy shining with the light of more than 300 trillion suns has been discovered using data from NASA's Wide-field Infrared Survey Explorer (WISE). The galaxy is the most luminous galaxy found to date and belongs to a new class of objects recently discovered by WISE -- extremely luminous infrared galaxies, or ELIRGs.

+Pierre Markuse , What i think is , That galaxy's brightest star is about to go for a Super -nova.... very soon.... that's why it is emitting this much luminousence.... ( Just an Hinch )

Impact crater or supervolcano caldera in 3D

The largest structure in this picture may hold a rather explosive secret: it could be remains of an ancient supervolcano. The images presented here were taken by the high-resolution stereo camera on ESA’s Mars Express on 26 November 2014, and focus on the Siloe Patera feature in the Arabia Terra region of Mars.

Partly Human Yeast Show A Common Ancestor’s Lasting Legacy

Despite a billion years of evolution separating humans from the baker’s yeast in their refrigerators, hundreds of genes from an ancestor that the two species have in common live on nearly unchanged in them both, say biologists at The University of Texas at Austin. The team created thriving strains of genetically engineered yeast using human genes and found that certain groups of genes are surprisingly stable over evolutionary time.

Ceres Bright Spots Seen Closer Than Ever

NASA's Dawn mission captured a sequence of images, taken for navigation purposes, of dwarf planet Ceres on May 16, 2015. The image showcases the group of the brightest spots on Ceres, which continue to mystify scientists. It was taken from a distance of 4,500 miles (7,200 kilometers) and has a resolution of 2,250 feet (700 meters) per pixel.

The insets are zoomed in on the brights spots, with the second inset just showing the bright features on the surface of Ceres.

NASA wants you to take a guess what those bright spots are, vote for your favourite here:

ALMA Reveals the Cradles of Dense Cores: the Birthplace of Massive Stars

A Taiwanese research team used the Atacama Large Millimeter/submillimeter Array (ALMA) to observe a large molecular gas clump named G33.92+0.11, where a cluster with massive stars is forming. The excellent imaging power of ALMA allowed to reveal with unprecedented detail, the fine structure of the molecular gas at the center of the region.

The ‘CAPEd’ Crusader: Goddard Technologist Advances CubeSat Concept for Planetary Exploration

The CubeSat Application for Planetary Entry Missions (CAPE) involves two modules: a service module that would propel the spacecraft to its celestial target and a separate planetary entry probe that could survive a rapid dive through the atmosphere of an extraterrestrial planet, all while reliably transmitting scientific and engineering data. This summer the Micro-Reentry Capsule (MIRCA) prototype will be tested during a high-altitude balloon mission.

Hubble Observes One-of-a-Kind Star Nicknamed 'Nasty'

Astronomers using NASA's Hubble Space Telescope have uncovered surprising new clues about a hefty, rapidly aging star whose behavior has never been seen before in our Milky Way galaxy. In fact, the star is so weird that astronomers have nicknamed it "Nasty 1," a play on its catalog name of NaSt1. Nasty 1 is thought to be a Wolf-Rayet star and have a companion, gravitational interactions between them may have created the gas disk.

Lawrence Livermore researchers use seismic signals to track above-ground explosions

Using seismic stations in Turkey, Livermore scientists Michael Pasyanos and Sean Ford created a method to determine source characteristics of near-earth surface explosions. They found the above-ground tunnel bomb blast under the Wadi al-Deif Army Base near Aleppo last spring was likely not as large as originally estimated and was closer to 40 tons.

SLAC Gears Up for Dark Matter Hunt with LUX-ZEPLIN

Researchers have come a step closer to building one of the world’s best dark matter detectors: The U.S. Department of Energy (DOE) recently signed off on the conceptual design of the proposed LUX-ZEPLIN (LZ) experiment and gave the green light for the procurement of some of its components.

Full story here:
https://www6.slac.stanford.edu/news/2015-05-20-slac-gears-dark-matter-hunt-lux-zeplin.aspx

What is dark matter?

Dark matter is a hypothetical kind of matter that cannot be seen with telescopes but accounts for most of the matter in the universe. The most likely hypothetical particle physics candidates for dark matter are WIMPs (weakly interacting massive particles).

Advanced Ligo gravitational wave hunt is green lit

One of the great physics experiments of our age looks ready to begin its quest. Scientists have held a dedication ceremony to inaugurate the Advanced LIGO (Laser Interferometer Gravitational-Wave Observatory) facilities in the US. This pair of widely separated laboratories will be hunting for gravitational waves.

Full story here:

What are gravitational waves?

Predicted almost 100 years ago by Albert Einstein in his theory of general relativity gravitational waves are ripples in the curvature of spacetime that propagate as a wave. More here:

Thanks, Pierre, for posting brain candy like this. I enjoy reading materials (on virtually any topic) that inspire an eyebrow-raise with a sense of wonder and excitement. Things science and tech however are a natural draw.

Caltech Astronomers Observe 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, the process by which a white dwarf becomes one has been unclear. New research seems to back up that that two different mechanisms lead to Type Ia supernovae.

The Cosmic Distance Ladder

Type Ia supernovae are an important part of establishing distances in the Universe as they serve as a standard candle. Having a known brightness, distances to the supernovae can be calculated. http://en.wikipedia.org/wiki/Cosmic_distance_ladder#Standard_candles

China is planning the first-ever landing on the far side of the Moon

Introduction
Hello!

Feel free to follow me or send me a message. (Also follow me on Twitter if you like.)

Some of you use circles to categorize people in different interest groups, and though I'm interested in lots of stuff you might wanna put me in circles like:
  • Science (General science and especially astronomy, physics and space technology)
  • Politics
Mostly I do post science related stuff but be aware I'll write about anything that comes to mind.

If you expect an answer please stay nice and don't be a dick, it would also be a good idea to write English or German. French is also possible, but since my French is quite rusty I'll most probably answer English.
