'Hedgehog' robots hop, tumble in microgravity

more »
Hopping, tumbling and flipping over are not typical maneuvers you would expect from a spacecraft exploring other worlds. Traditional Mars rovers, for example, roll around on wheels, and they can't operate upside-down. But on a small body, such as an asteroid or a comet, the low-gravity conditions and rough surfaces make traditional driving all the more hazardous. Enter Hedgehog: a new concept for a robot that is specifically designed to overcome the challenges of traversing small bodies.

Hubble survey unlocks clues to star birth in neighboring galaxy

more »
In an intensive citizen-science-aided survey of Hubble telescope images of 2,753 young, blue star clusters in the neighboring Andromeda galaxy (M31), astronomers have found that M31 and our own galaxy have a similar percentage of newborn stars based on mass. By nailing down what percentage of stars have a particular mass within a cluster (the Initial Mass Function), scientists can better interpret the light from distant galaxies and understand the formation history of stars in our universe.

Comet hitchhiker would take tour of small bodies

more »
Catching a ride from one solar system body to another isn't easy. You have to figure out how to land your spacecraft safely and then get it on its way to the next destination. The landing part is especially tricky for asteroids and comets, which have low gravitational pull. A concept called Comet Hitchhiker, developed at NASA's Jet Propulsion Laboratory, Pasadena, California, puts forth a new way to get into orbit and land on comets and asteroids, using the kinetic energy -- the energy of motion -- of these small bodies

What happened to early Mars' atmosphere? New study eliminates one theory

more »
Scientists may be closer to solving the mystery of how Mars changed from a world with surface water billions of years ago to the arid Red Planet of today. A new analysis of the largest known deposit of carbonate minerals on Mars suggests that the original Martian atmosphere may have already lost most of its carbon dioxide by the era of valley network formation.

Hubble Survey Unlocks Clues to Star Birth in Neighboring Galaxy

Get larger image formats

All stars are not created equal. They can vary in mass by over a factor of 1,000. Our sun is classified as a diminutive yellow dwarf. What's more, stars are not born in isolation, but inside giant molecular clouds of hydrogen. The question has been: what fraction of stars precipitate out of these clouds into clusters that contain blue giants, yellow dwarfs, and red dwarfs? It's like asking if all automobile manufacturers fabricate the same proportion of trucks, SUVs, sedans, and subcompacts. The best way to address the question is not to look around our Milky Way which we are inside but far out into space to the neighboring Andromeda galaxy, 2.5 million light-years away. Embedded in a sweeping Hubble Space Telescope mosaic of 117 million stars in the galaxy's disk are 2,753 star clusters. Hubble astronomers found that, for whatever reason, nature apparently cooks up stars like batches of cookies. There is a consistent distribution from massive stars to small stars. It is surprising to find that this ratio is the same across our neighboring galaxy (as well as inside our stellar neighborhood in the Milky Way), given the complex physics of star formation.

At Saturn, one of these rings is not like the others

more »
When the sun set on Saturn's rings in August 2009, scientists on NASA's Cassini mission were watching closely. It was the equinox -- one of two times in the Saturnian year when the sun illuminates the planet's enormous ring system edge-on. The event provided an extraordinary opportunity for the orbiting Cassini spacecraft to observe short-lived changes in the rings that reveal details about their nature.

Magnetic wormhole connecting two regions of space created for the first time

more »
"Wormholes" are cosmic tunnels that can connect two distant regions of the universe, and have been popularized by the dissemination of theoretical physics and by works of science fiction like Stargate, Star Trek or, more recently, Interstellar. Using present-day technology it would be impossible to create a gravitational wormhole, as the field would have to be manipulated with huge amounts of gravitational energy, which no-one yet knows how to generate. In electromagnetism, however, advances in metamaterials and invisibility have allowed researchers to put forward several designs to achieve this.

Arp 159 and NGC 4725

more »
Pointy stars and peculiar galaxies span this cosmic snapshot, a telescopic view toward the well-groomed constellation Coma Berenices. Bright enough to show off diffraction spikes, the stars are in the foreground of the scene, well within our own Milky Way. But the two prominent galaxies lie far beyond our own, some 41 million light-years distant. Also known as NGC 4747, the smaller distorted galaxy at left is the 159th entry in the Arp Atlas of Peculiar Galaxies, with extensive tidal tails indicative of strong gravitational interactions in its past. At about a 100,000 light-years across, its likely companion on the right is the much larger NGC 4725. At first glance NGC 4725 appears to be a normal spiral galaxy, its central region dominated by the yellowish light of cool, older stars giving way to younger hot blue star clusters along dusty spiral outskirts. Still, NGC 4725 does look a little odd with only one main spiral arm.
