MOND predicts dwarf galaxy feature prior to observations

MOND, a modified law of gravity, correctly predicted in advance of observations the velocity dispersion - the average speed of stars within a galaxy relative to each other - in 10 dwarf satellite galaxies of the Milky Way's giant neighbor Andromeda. MOND also detected subtle differences in gravity fields that dark matter theory says should be uniform.

Oldest Solar Twin Identified - ESO's VLT provides new clues to help solve lithium mystery

A team led by astronomers in Brazil has used ESO's Very Large Telescope to study the oldest solar twin known to date. Located 250 light-years away, the star HIP 102152 is more like the Sun than any other solar twin - except that it is nearly four billion years older. This older twin may be host to rocky planets and gives us an unprecedented chance to see how the Sun will look when it ages.

Scientists detect magmatic water on Moon's surface

Scientists have detected magmatic water - water that originates from deep within the Moon's interior - on the surface of the Moon. These findings represent the first such remote detection of this type of lunar water, and were arrived at using data from NASA's Moon Mineralogy Mapper (M3).

Spitzer telescope celebrates 10 years in space

Ten years after a Delta II rocket launched NASA's Spitzer Space Telescope, lighting up the night sky over Cape Canaveral, Fla., the fourth of the agency's four Great Observatories continues to illuminate the dark side of the cosmos with its infrared eyes.

A fluffy disk around a baby star

An international team of astronomers that are members of the Strategic Exploration of Exoplanets and Disks with Subaru Telescope (SEEDS) Project has observed a disk around the young star RY Tau (Tauri). The team's analysis of the disk shows that a 'fluffy' layer above it is responsible for the scattered light observed in the infrared image.

Hubble takes movies of space slinky

Astronomers have assembled, from more than 13 years of observations from NASA's Hubble Space Telescope, a series of time-lapse movies showing a jet of superheated gas - 5,000 light-years long - as it is ejected from a supermassive black hole.

NASA's Fermi enters extended mission (w/video)

On Aug. 11, Fermi entered an extended phase of its mission - a deeper study of the high-energy cosmos. This is a significant step toward the science team's planned goal of a decade of observations, ending in 2018.

What's for dinner on Mars?

Imagine finding freeze-dried meats and fruits, dehydrated vegetables, egg crystals, ghee-like anhydrous butter, powdered milk and chipotle peppers in your kitchen, but not a morsel of fresh food. That's what happened to six 'astronauts' who lived in a simulated Martian base on the slopes of Hawaii's Mauna Loa volcano from April 16 to Aug. 13 as part of a HI-SEAS mission.

Starbirth surprisingly energetic: ALMA observations give new insights into protostars

While observing a newborn star, astronomers using the Atacama Large Millimeter/submillimeter Array (ALMA) telescope discovered twin jets of matter blasting out into space at record-breaking speed. These surprisingly forceful molecular 'winds' could help refine our understanding of how stars impact their cloudy nurseries and shape their emerging stellar systems.

Pulsars make a GPS for the cosmos

CSIRO scientists have written software that could guide spacecraft to Alpha Centauri, show that the planet Nibiru doesn't exist... and prove that the Earth goes around the Sun.

Spaceflight alters bacterial social networks

In two NASA-funded studies biofilms grown aboard the International Space Station bound space shuttle were compared with those grown on the ground. The study results show for the first time that spaceflight changes the behavior of bacterial communities.
