In a cosmic battle of sorts taking place in the centers of galaxies, stellar forces muscle up and kick out brewing invisible matter. The result, finds a new study, evens out the amount of invisible matter held in galactic cores, resolving a cosmological puzzle. picked by AutumnLotus 2 years ago

"Physicists have been taking baby steps toward creating a full-fledged quantum computer faster and more powerful than any computer in existence, by making quantum processors capable of performing individual tasks. Now a group at the National Institute of Standards and Technology (NIST) has developed the world's first universal programmable quantum computer that can run any program that's pos... read full post picked by sidran32 2 weeks ago

It's the experiment dark matter hunters love to hate. But physicists working on the DAMA (DArk MAtter) experiment might have the last laugh later this week. Rumour has it that, later this week, an Italian lab will claim to have found dark matter, at a conference in Venice, Italy. picked by AutumnLotus 2 years ago

ESA’s orbiting X-ray observatory XMM-Newton has been used by a team of international astronomers to uncover part of the missing matter in the universe. 10 years ago, scientists predicted that about half of the missing ‘ordinary’ or normal matter made of atoms exists in the form of low-density gas, filling vast spaces between galaxies. picked by AutumnLotus 2 years ago

Small, ultrafaint "hobbit" galaxies recently found hovering around our Milky Way are comprised almost entirely of dark matter, a new study confirms. Dark matter is a mysterious substance scientists think accounts for most of the mass in the universe but that is invisible to current instruments. picked by AutumnLotus 2 years ago

Astronomers are using the NASA/ESA Hubble Space Telescope to dissect one of the largest structures in the Universe as part of a quest to understand the violent lives of galaxies. Hubble is providing indirect evidence of unseen dark matter tugging on galaxies in the crowded, rough-and-tumble environment of a massive supercluster of hundreds of galaxies. picked by AutumnLotus 2 years ago

Should we abandon this enigmatic concept of invisible matter that exerts gravitational attraction but is otherwise undetectable? Could it be that we simply do not understand the long-range behavior of gravity? picked by bernardblack 2 months ago

About 70 percent is dark energy, and around 22 percent of the universe is made up of dark matter. Dark matter makes up a substantial part of the universe. Knowing what it is would answer a crucial question about the universe as a whole. picked by braveheart 3 years ago

The fastest flows of matter in the universe shoot out of dying stars at more than 99.999% the speed of light, new observations reveal. picked by DrNothing 2 years ago

The identity of the mysterious dark matter thought to pervade the universe has eluded astrophysicists for decades. Now, for the first time a team hopes to look inside the sun for one of the prime candidates. picked by AutumnLotus 1 year ago

Matter is built on flaky foundations. Physicists have now confirmed that the apparently substantial stuff is actually no more than fluctuations in the quantum vacuum. picked by AutumnLotus 1 year ago

Two galaxy clusters collided with each other. The image gathered from visible light as well as the way that gravity effected the light provides striking evidence for dark matter and insight into its properties. More in depth info here in pdf form picked by 2manyusernames 1 year ago

When dark matter is destroyed, it leaves behind a burst of exotic particles, according to theory. Now scientists have found a possible signature of these remains. The discovery could help prove the existence of dark matter and reveal what it's made of. picked by AutumnLotus 8 months ago

Tantalising traces of the building blocks of life have been spotted in nearby galaxies. However, working out the identity of these carbon-containing molecules, and when they became abundant, is proving tricky. picked by AutumnLotus 2 years ago

Astronomers have used two different telescopes simultaneously to study the violent flares from the supermassive black hole in the centre of the Milky Way. They have detected outbursts from this region, known as Sagittarius A*, which reveal material being stretched out as it orbits in the intense gravity close to the central black hole. picked by AutumnLotus 1 year ago

Much of the gaseous mass of the universe is bound up in a tangled web of cosmic filaments that stretch for hundreds of millions of light-years, according to a new supercomputer study. The study indicated a significant portion of the gas is in the filaments -- which connect galaxy clusters -- hidden from direct observation in enormous gas clouds in intergalactic space known as the Warm-Hot Interga... read full post picked by AutumnLotus 2 years ago

A swift adapts the shape of its wings to the immediate task at hand: folding them back to chase insects, or stretching them out to sleep in flight. Ten Dutch and Swedish scientists, based in Wageningen, Groningen, Delft, Leiden, and Lund, have shown how 'wing morphing' makes swifts such versatile flyers. picked by AutumnLotus 3 years ago

Two Canadian astronomers think there is a good reason dark matter, a mysterious substance thought to make up the bulk of matter in the universe, has never been directly detected: It doesn't exist. picked by AutumnLotus 2 years ago

Perhaps the first stars in the newborn universe did not shine, but instead were invisible “dark stars” 400 to 200,000 times wider than the sun and powered by the annihilation of mysterious dark matter. The study calculated how the birth of the first stars almost 13 billion years ago might have been influenced by the presence of dark matter – the unseen, yet-unidentified stuff tha... read full post picked by AutumnLotus 2 years ago
