Researchers make most precise measurement yet of the expanding universe

April 10, 2014 1:15 pm | by Barbara Kennedy, Penn State | News | Comments

Astronomers at Penn State and other institutions participating in the Sloan Digital Sky Survey have used 140,000 distant quasars to measure the expansion rate of the universe when it was only one-quarter of its present age. This measurement is the best yet of the expansion rate at any epoch in the last 13 billion years during the history of the universe.

Gravity measurements confirm subsurface ocean on Enceladus

April 7, 2014 9:18 am | by Kimm Fesenmaier, Caltech | News | Comments

In 2005, NASA's Cassini spacecraft sent pictures back to Earth depicting an icy Saturnian moon spewing water vapor and ice from fractures, known as "tiger stripes," in its frozen surface. It was big news that tiny Enceladus was such an active place. Since then, scientists have hypothesized that a large reservoir of water lies beneath that icy surface, possibly fueling the plumes.

How Earth got its plated shell

April 7, 2014 9:03 am | by Eric Gershon, Yale Univ. | News | Comments

New Yale Univ.-led research suggests how and when Earth came to develop one of its most distinct features—rigid tectonic plates—and why Venus, Earth’s twin-like neighbor, never has. Earth has a unique network of shifting plates embedded in its cold and rocky outermost layer, the lithosphere. The motion of these plates drives many Earth processes, while also stabilizing the planet’s climate and enabling life.

After insisting that space relations wouldn't be altered by earthly politics, NASA announced it was severing ties with Russia except for the International Space Station. NASA employees can't travel to Russia or host visitors until further notice. They're also barred from emailing or holding teleconferences with their Russian counterparts because of Russia's actions in Ukraine, according to a memo sent to workers.

The ringed asteroid

March 28, 2014 11:51 am | News | Comments

Benefited from a rare occultation on June 3, 2013, researchers observed the asteroid Chariklo when it passed by a star that concealed it for several seconds. Although the astronomer planned only to measure its size, they were surprised to discover this “centaur”, which has an unstable orbit that passes through the outer planets, has two thin rings made of ice. It is only the fifth Solar System object to exhibit such a system.

It's been dubbed “Bryan” by its creators, and the plan is to send it to Mars in 2018 as part of the European Space Agency's ExoMars program, an ambitious plan that begins in 2016 with the launch of a Mars orbiter and demonstrator landing module.

Newfound pink world lurks at solar system fringes

March 27, 2014 9:30 am | by Alicia Chang, AP Science Writer | News | Comments

Until now, the lone known resident in the region of the solar system beyond Pluto was an oddball dwarf planet spotted in 2003 named Sedna. For years, astronomers hunted in vain for other Sednas in the little-studied fringes of the solar system. Now, they’ve found one: a pink frozen world 7.5 billion miles from the sun. And astronomer think they will find others.

NIST gives astronomers better ruler in search for extrasolar planets

March 26, 2014 2:14 pm | News | Comments

As a planet orbits, its gravity makes its parent star wobble a tiny bit, resulting in slight color changes in the star's light due to the Doppler effect. A high-quality reference spectrum allows scientists to make a comparison to find planets. Now, NIST has made extensive new measurements of thorium, a heavy element often used in emission lamps that help provide that fixed ruler. The work has more than doubled the number of spectral lines.

A river of plasma, guarding against the sun

March 7, 2014 7:39 am | by Jennifer Chu, MIT News Office | News | Comments

The Earth’s magnetic field, or magnetosphere, stretches from the planet’s core out into space, where it meets the solar wind, a stream of charged particles emitted by the sun. For the most part, the magnetosphere acts as a shield to protect the Earth from this high-energy solar activity. But when this field comes into contact with the sun’s magnetic field, powerful electrical currents from the sun can stream into Earth’s atmosphere.
