Tiny Young Galaxies "Full of Stars" Discovered

9 years ago from National Geographic

Nine distant galaxies, each small enough to fit within the central hub of the Milky Way, contain enough stars to weigh in at about 200 billion times the mass of...

Cassini finds rhythm in Saturn's rings

9 years ago from European Space Agency

Two of Saturn's rings have been found by NASA's Cassini spacecraft to contain orderly lines of densely grouped, boulder-size icy particles that extend outward across the rings like ripples from...

Cassini finds mingling moons may share a dark past

9 years ago from European Space Agency

Despite the incredible diversity of Saturn’s icy moons, theirs is a story of great interaction. Some are pock-marked, some seemingly dirty, others pristine, one spongy, one two-faced, some still spewing...

Scientists Discover Record Fifth Planet Orbiting Nearby Star

Astronomers have announced the discovery of a fifth planet circling 55 Cancri, a star beyond our solar system.

Spitzer Spies a Stellar Bubble Blower

A new image from NASA's Spitzer Space Telescope shows a baby star 1,140 light-years away from Earth blowing two massive "bubbles." But instead of bubble gum, this youngster, called HH...

NASA Sees Arctic Ocean Circulation Do an About-Face

PASADENA, Calif. -- A team of NASA and university scientists has detected an ongoing reversal in Arctic Ocean circulation triggered by atmospheric circulation changes that vary on decade-long time scales.

NASA Mega-Telescope Gears Up to Study Cosmos

NASA has selected three teams of scientists to begin studying disks of dust around nearby stars starting in February 2008, using the Keck Interferometer in Mauna Kea, Hawaii.

Cassini Team Recruits Next Generation of Scientists

NASA's Cassini-Huygens Mission to Saturn has some young new participants. A 10th-grade student in Delaware, a high school senior in California, and an 8th-grade American student in France are the...

Ulysses Spacecraft Flies Over Sun's North Pole

The Ulysses spacecraft today is making a rare flyby of the sun's north pole. Unlike any other spacecraft, Ulysses is able to sample winds at the sun's poles.

Public Invited to Celebrate Anniversary of Explorer 1

A half--century ago, the Jet Propulsion Laboratory's Explorer 1 spacecraft became America's first Earth-orbiting satellite when it sailed into space on Jan. 31, 1958.

Cosmic Suburbia Is a Better Breeding Ground for Stars

New observations from NASA's Spitzer Space Telescope suggest that galaxies prefer to raise stars in cosmic suburbia rather than in "big cities."

Stardust Comet Dust Resembles Asteroid Materials

Contrary to scientists' expectations, much of the comet dust returned by NASA's Stardust mission formed very close to the young sun and was somehow differentiated from the other materials that...

NASA and the Beatles Celebrate Anniversaries by Beaming Song 'Across the Universe' Into Deep Space

For the first time ever, NASA will beam a song - The Beatles "Across the Universe" -- directly into deep space at 4 p.m. Pacific Time on Monday, Feb. 4.

NASA's Deep Impact Begins Hunt for Alien Worlds

NASA's Deep Impact spacecraft is aiming its largest telescope at five stars in a search for alien planets as it enters its extended mission, called Epoxi.

Students Paint a Window to Saturn

Art students have literally left their mark at JPL with a gigantic, multi-wall mural of the Cassini spacecraft's latest discoveries about Saturn and its moons.

Mars Rovers Sharpen Questions About Livable Conditions

Like salt used as a preservative, high concentrations of dissolved minerals in the wet, early-Mars environment known from discoveries by NASA's Opportunity rover may have thwarted any microbes from developing...

International Solar Mission to End Following Stellar Performance

The joint NASA and European Space Agency Ulysses mission to study the sun and its influence on surrounding space is likely to cease operations in the next few months.

Spitzer's Eyes Perfect for Spotting Diamonds in the Sky

Diamonds may be rare on Earth, but surprisingly common in space -- and the super-sensitive infrared eyes of NASA's Spitzer Space Telescope are perfect for scouting them.

NASA Views Landing Site Through Eyes of Future Moon Crew

NASA has obtained the highest resolution terrain mapping to date of the moon's rugged south polar region, with a resolution to 20 meters (66 feet) per pixel.

A team of astronomers, led by JPL's Mark Swain, has made the first detection ever of an organic molecule in the atmosphere of a Jupiter-sized planet orbiting another star.

NASA Mission Finds New Clues to Guide Search for Life on Mars

NASA's Mars Odyssey orbiter has found evidence of salt deposits. These deposits point to places where water once was abundant and where evidence might exist of possible Martian life from...
