GOODS-Herschel reveals gas mass role in creating fireworks versus beacons of...
(PhysOrg.com) -- A study of galaxies in the deepest far-infrared image of the sky, obtained by the Herschel Space Observatory, highlights the two contrasting ways that stars formed in galaxies up to 12...
View ArticleTeam finds asteroids were bombarded by iron loving elements too
(Phys.org) -- A team made up of a diverse group of researchers has found after studying the composition of several asteroids that most such planetesimals had an abundance of highly siderophile elements...
View ArticleWhen stellar metallicity sparks planet formation
New research predicts the criteria needed for Earth-like planets to form around a star that have one-tenth the metallicity of our Sun. If researchers find small, rocky planets orbiting stars with lower...
View Article'Cosmic mirages' confirm accelerated cosmic expansion
(Phys.org) -- An international team of researchers led by Masamune Oguri at Kavli IPMU and Naohisa Inada at Nara National College of Technology conduced an unprecedented survey of gravitationally...
View ArticleA new paradigm for active galactic nuclei
(Phys.org) -- Seyfert galaxies are similar to normal galaxies like our own Milky Way except in one critical respect: their nuclei are fantastically bright, in extreme instances as luminous as 100...
View ArticleGhostly gamma-ray beams blast from Milky Way's center
(Phys.org) -- As galaxies go, our Milky Way is pretty quiet. Active galaxies have cores that glow brightly, powered by supermassive black holes swallowing material, and often spit twin jets in opposite...
View ArticleX-ray 'echoes' map a supermassive black hole's environs
(Phys.org) -- An international team of astronomers using data from the European Space Agency's (ESA) XMM-Newton satellite has identified a long-sought X-ray "echo" that promises a new way to probe...
View ArticleAccreting black holes in galaxies
(Phys.org) -- Seyfert galaxies are like normal galaxies, our own Milky Way included, except in one critical respect: their nuclei are fantastically bright. In some instances they are as luminous as 100...
View ArticleWhy is Earth so dry?
(Phys.org) -- With large swaths of oceans, rivers that snake for hundreds of miles, and behemoth glaciers near the north and south poles, Earth doesn't seem to have a water shortage. And yet, less than...
View ArticleStar's 'cry' heralds new era for testing relativity
(Phys.org) -- Last year, astronomers discovered a quiescent black hole in a distant galaxy that erupted after shredding and consuming a passing star. Now researchers have identified a distinctive X-ray...
View ArticleMagnetic turbulence trumps collisions to heat solar wind
(Phys.org) -- New research, led by University of Warwick physicist Dr Kareem Osman, has provided significant insight into how the solar wind heats up when it should not. The solar wind rushes outwards...
View ArticleDestroyed coastal habitats produce significant greenhouse gas
Destruction of coastal habitats may release as much as 1 billion tons of carbon emissions into the atmosphere each year, 10 times higher than previously reported, according to a new Duke led study.
View ArticleFor the first time, astronomers have measured the radius of a black hole
(Phys.org)—The point of no return: In astronomy, it's known as a black hole—a region in space where the pull of gravity is so strong that nothing, not even light, can escape. Black holes that can be...
View ArticleAccumulating stellar 'stuff' to form galaxies
European researchers studied accumulation of stellar material onto stars and black holes to gain insight into the growth and evolution of galaxies.
View ArticleResearchers detect the brightest flare ever observed in our galaxy's black hole
As black holes go, Sagittarius A* is relatively low-key. The black hole at the center of our galaxy emits very little energy for its size, giving off roughly as much energy as the sun, even though it...
View ArticleGreenland rocks provide evidence of Earth formation process
(Phys.org)—Rocks dating back 3.4 billion years from south-west Greenland's Isua mountain range have yielded valuable information about the structure of the Earth during its earliest stages of...
View ArticleComputer model shows strong magnetic fields may alter alignment of black hole...
(Phys.org)—Researchers from Stanford University and Princeton suggest in a paper they've had published in the journal Science that magnetic fields associated with some black holes may be strong enough...
View ArticleResearch model suggests moons of some planets developed from rings
(Phys.org)—French researchers Sébastien Charnoz and Aurélien Crida have proposed in a paper published in the journal Science that moons that orbit some of the planets in our solar system came about due...
View ArticleBlack hole jets might be molded by magnetism
Even though black holes—by their definition and very nature—are the ultimate hoarders of the Universe, gathering and gobbling up matter and energy to the extent that not even light can escape their...
View ArticleCommon physics among black holes
(Phys.org)—Black holes range from modest objects formed when individual stars end their lives to behemoths billions of times more massive that rule the centers of galaxies. A new study using data from...
