New research suggests that near-Earth encounters can 'shake' asteroids
(PhysOrg.com) -- For decades, astronomers have analyzed the impact that asteroids could have on Earth. New research by MIT Professor of Planetary Science Richard Binzel examines the opposite scenario: that ...
New research resolves conflict in theory of how galaxies form (w/ Video)
(PhysOrg.com) -- For more than two decades, the cold dark matter theory has been used by cosmologists to explain how the smooth universe born in the big bang more than 13 billion years ago evolved into the ...
What will the Large Hadron Collider reveal?
With its successful test run at the end of 2009, the Large Hadron Collider near Geneva, Switzerland, seized the world record for the highest-energy particle collisions created by mankind. We can now reflect ...

Jupiter had temporary moon for 12 years
Comet 147P/Kushida-Muramatsu was captured as a temporary moon of Jupiter in the mid-20th century and remained trapped in an irregular orbit for about twelve years.
The bend in the Appalachian mountain chain is finally explained
The 1500 mile Appalachian mountain chain runs along a nearly straight line from Alabama to Newfoundland—except for a curious bend in Pennsylvania and New York State. Researchers from the College of New ...
Tips from space give long-range warning of flood risk
Satellite monitoring of tiny changes in the gravitational field of river basins may give up to 11 months' warning of disastrous floods, a study published on Sunday said.
Darwin meets Newton: Evolution and the mass of the galaxy
If the solution to a problem does not reveal itself straight away then why not let your initial guesswork evolve? That's the approach we've taken in trying to determine the mass of our galaxy by mapping the ...
Spiral galaxy spills blood and guts
(Phys.org) —This new Hubble image shows spiral galaxy ESO 137-001, framed against a bright background as it moves through the heart of galaxy cluster Abell 3627. This cluster is violently ripping the spiral's ...
Indian Mars mission on track, makes first engine burns
India's Mars spacecraft has completed the first of a series of engine firings designed to free it from Earth's gravitational pull and propel it towards the Red Planet, scientists said Friday.
World timekeepers wrangle over scrapping leap second
Timekeeping experts failed Friday to reach a decision on scrapping the four-decade-old practice of adding extra seconds to clocks, a system opponents say causes headaches in a hi-tech, interconnected world.
Astronomers explain why disk galaxies eventually look alike
(Phys.org) —It happens to all kinds of flat, disk galaxies – whether they're big, little, isolated or crowded in a cluster. They all grow out of their irregular, clumped appearance and their older stars ...
Cosmic turbulences result in star and black hole formation
Just how stars and black holes in the Universe are able to form from rotating matter is one of the big questions of astrophysics. What we do know is that magnetic fields figure prominently into the picture. ...
Gravitational tide the secret of Saturn's weird moon
Enceladus, a white moon of Saturn with ice-spewing volcanoes, owes its strangeness to tides of gravitational forces exerted by its mother, a study in Nature said on Wednesday.
