Rosetta's comet dissected in detail

Star Stuff - Tue, 01/27/2015 - 19:57
The first detailed scientific papers paint a complex portrait of comet 67P. Also; a new look at Eta Carinae, and our planet's close encounter with a half-kilometre-wide asteroid.

NASA's Dawn spacecraft captures best-ever view of dwarf planet Ceres

Science Daily - Tue, 01/27/2015 - 14:11
NASA's Dawn spacecraft has returned the sharpest images ever seen of the dwarf planet Ceres. The images were taken 147,000 miles (237,000 kilometers) from Ceres on Jan. 25, and represent a new milestone for a spacecraft that soon will become the first human-made probe to visit a dwarf planet.

Asteroid that flew past Earth has moon

Science Daily - Tue, 01/27/2015 - 14:06
Scientists working with NASA's 230-foot-wide (70-meter) Deep Space Network antenna at Goldstone, California, have released the first radar images of asteroid 2004 BL86. The images show the asteroid, which made its closest approach on Jan. 26, 2015 at 8:19 a.m. PST (11:19 a.m. EST) at a distance of about 745,000 miles (1.2 million kilometers, or 3.1 times the distance from Earth to the moon), has its own small moon.

'Yellowballs' are part of the development of massive star

Science Daily - Tue, 01/27/2015 - 13:11
Citizen scientists wanted to know: What are the yellow objects on these infrared images from the Spitzer Space Telescope? Astronomers now report that the "yellowballs" are part of the development of massive stars.

Bubbles from the galactic center: A key to understanding dark matter and our galaxy's past?

Science Daily - Tue, 01/27/2015 - 11:14
The astrophysicists who discovered two enormous radiation bubbles in the center of our galaxy discuss what they may tell us about the Milky Way and how they could help in the search for dark matter.

Ancient star system reveals Earth-sized planets forming near start of universe

Science Daily - Tue, 01/27/2015 - 11:14
A Sun-like star with orbiting planets, dating back to the dawn of the Galaxy, has been discovered by an international team of astronomers. At 11.2 billion years old, it is the oldest star with Earth-sized planets ever found and proves that such planets have formed throughout the history of the Universe.

NOAA's DSCOVR going to a 'far out' orbit

Science Daily - Mon, 01/26/2015 - 17:06
Many satellites that monitor the Earth orbit relatively close to the planet, while some satellites that monitor the sun orbit our star. DSCOVR will keep an eye on both, with a focus on the sun. To cover both the Earth and sun, it will have an unusual orbit in a place called L1.

Gigantic ring system around J1407b much larger, heavier than Saturn's

Science Daily - Mon, 01/26/2015 - 13:52
Astronomers have discovered that the ring system that they see eclipse the very young Sun-like star J1407 is of enormous proportions, much larger and heavier than the ring system of Saturn.

Swarm of microprobes to head for Jupiter

Science Daily - Mon, 01/26/2015 - 11:23
A swarm of tiny probes each with a different sensor could be fired into the clouds of Jupiter and grab data as they fall before burning up in the gas giant planet's atmosphere. The probes would last an estimated 15 minutes according to planetary scientists. Transmitting 20 megabits of data over 15 minutes would be sufficient to allows scientists to get a picture of a large part of the atmosphere of the planet.

Helicopter could be 'scout' for Mars rovers

Science Daily - Mon, 01/26/2015 - 10:51
Getting around on Mars is tricky business. Each NASA rover has delivered a wealth of information about the history and composition of the Red Planet, but a rover's vision is limited by the view of onboard cameras, and images from spacecraft orbiting Mars are the only other clues to where to drive it. To have a better sense of where to go and what's worth studying on Mars, it could be useful to have a low-flying scout.
