NASA - National Aeronautics and Space AdministrationMountain View, CA – NASA’s Global Hawk research aircraft returned to its base at NASA’s Armstrong Flight Research Center at Edwards Air Force Base, CA, early Friday morning March 14th, marking the completion of flights in support of this year’s Airborne Tropical Tropopause Experiment (ATTREX), a multi-year NASA airborne science campaign.

On February 13th, the autonomously operated aircraft began conducting science flights from Andersen Air Force Base on Guam in the western Pacific region on a mission to track changes in the upper atmosphere and help researchers understand how these changes affect Earth’s climate.

Over 700 new planets discovered by NASA’s Kepler Mission

 

Written by Whitney Clavin
NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, CA – NASA’s Kepler mission announced Wednesday the discovery of 715 new planets. These newly verified worlds orbit 305 stars, revealing multiple-planet systems much like our own solar system.

Nearly 95 percent of these planets are smaller than Neptune, which is almost four times the size of Earth. This discovery marks a significant increase in the number of known small-sized planets more akin to Earth than previously identified exoplanets, which are planets outside our solar system.

The artist concept depicts "multiple-transiting planet systems," which are stars with more than one planet. (NASA)

NASA’s Hubble Space Telescope finds new Moon orbiting Neptune

 

NASA - National Aeronautics and Space AdministrationWashington, D.C. – A new moon orbiting the distant blue-green planet Neptune has been discovered NASA’s Hubble Space Telescope. It is the 14th known to be circling the giant planet.

The moon, designated S/2004 N 1, is estimated to be no more than 12 miles across, making it the smallest known moon in the Neptunian system. It is so small and dim that it is roughly 100 million times fainter than the faintest star that can be seen with the naked eye.

This diagram shows the orbits of several moons located close to the planet Neptune. All of them were discovered in 1989 by NASA's Voyager 2 spacecraft, with the exception of S/2004 N 1, which was discovered in archival Hubble Space Telescope images taken from 2004 to 2009. The moons all follow prograde orbits and are nestled among Neptune's rings (not shown).

NASA’s Kepler mission to discover Earth size planets finds 461 New Planet Candidates

 

Written by Whitney Clavin
NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, CA – NASA’s Kepler mission Monday announced the discovery of 461 new planet candidates. Four of the potential new planets are less than twice the size of Earth and orbit in their sun’s “habitable zone,” the region in the planetary system where liquid water might exist on the surface of a planet.

Based on observations conducted from May 2009 to March 2011, the findings show a steady increase in the number of smaller-size planet candidates and the number of stars with more than one candidate.

NASA Scientists strike it rich with Meteorite recovery

 

Written by Karen Jenvey
NASA’s Ames Research Center

NASA - National Aeronautics and Space AdministrationMoffett Field, CA – Scientists found treasure when they studied a meteorite that was recovered April 22nd, 2012 at Sutter’s Mill, the gold discovery site that led to the 1849 California Gold Rush. Detection of the falling meteorites by Doppler weather radar allowed for rapid recovery so that scientists could study for the first time a primitive meteorite with little exposure to the elements, providing the most pristine look yet at the surface of primitive asteroids.

An international team of 70 researchers reported in an issue of “Science” that this meteorite was classified as a Carbonaceous-Mighei or CM-type carbonaceous chondrite and that they were able to identify for the first time the source region of these meteorites.

Fragments of the Sutter’s Mill meteorite fall collected by NASA Ames and SETI Institute meteor astronomer Dr. Peter Jenniskens in the evening of Tuesday April 24th, two days after the fall. This was the second recovered find. (Image credit: NASA / Eric James)

NASA’s Hubble Space Telescope images reveal a Fifth Moon Orbiting Pluto

 

NASA - National Aeronautics and Space AdministrationMountain View, CA – A team of astronomers using NASA’s Hubble Space Telescope is reporting the discovery of another moon orbiting the icy dwarf planet Pluto.

The moon is estimated to be irregular in shape and 6 to 15 miles across. It is in a 58,000-mile-diameter circular orbit around Pluto that is assumed to be co-planar with the other satellites in the system.

“The moons form a series of neatly nested orbits, a bit like Russian dolls,” said team lead Mark Showalter of the SETI Institute in Mountain View, CA.

The green circle marks the newly discovered moon, designated P5, as photographed by Hubble's Wide Field Camera 3 on July 7th. P4 was uncovered in Hubble imagery in 2011. (Credit: NASA; ESA; M.

NASA’s Kepler Space Telescope Detects Possible Evaporating Planet

 

Written by Michele Johnson
NASA’s Ames Research Center

NASA - National Aeronautics and Space AdministrationMoffett Field, CA – Astronomers may have detected evidence of a possible planet disintegrating under the searing heat of its host star located 1,500 light-years from Earth. Similar to a debris-trailing comet, the super Mercury-size planet candidate is theorized to fashion a dusty tail. But the tail won’t last for long.

Scientists calculate that, at the current rate of evaporation, the dusty world could be completely vaporized within 200 million years.

The artist's concept depicts a comet-like tail of a possible disintegrating super Mercury-size planet candidate as it transits its parent star named KIC 12557548. At an orbital distance of only twice the diameter of its star, the surface temperature of the potential planet is estimated to be a sweltering 3,300 degrees Fahrenheit. At such a high temperature, the surface would melt and evaporate. (Image credit: NASA/JPL-Caltech)

Kepler Discovers a Planet with Two Suns

 

Written by Dr. Tony Phillips
Science@NASA

NASA - National Aeronautics and Space AdministrationWashington, D.C. – The existence of a world with a double sunset, as portrayed in the film Star Wars more than 30 years ago, is now scientific fact. NASA’s Kepler mission has made the first unambiguous detection of a circumbinary planet — a planet orbiting two stars — 200 light-years from Earth.

Unlike Star Wars’ Tatooine, the planet is cold, gaseous and not thought to harbor life, but its discovery demonstrates the diversity of planets in our galaxy. Previous research has hinted at the existence of circumbinary planets, but clear confirmation proved elusive. Kepler detected such a planet, known as Kepler-16b, by observing transits, where the brightness of a parent star dims from the planet crossing in front of it.

NASA’s Hubble Discovers Another Moon Around Pluto

 
NASAWashington, D.C. - Astronomers using the Hubble Space Telescope discovered a fourth moon orbiting the icy dwarf planet Pluto. The tiny, new satellite — temporarily designated P4 — was uncovered in a Hubble survey searching for rings around the dwarf planet.
 
The new moon is the smallest discovered around Pluto. It has an estimated diameter of 8 to 21 miles (13 to 34 km). By comparison, Charon, Pluto’s largest moon, is 648 miles (1,043 km) across, and the other moons, Nix and Hydra, are in the range of 20 to 70 miles in diameter (32 to 113 km).
