NASA’s Kepler Space Telescope finds Earth size planet around a star like our sun in the Habitable Zone

NASA - National Aeronautics and Space AdministrationPasadena, CA – NASA’s Kepler mission has confirmed the first near-Earth-size planet in the “habitable zone” around a sun-like star. This discovery and the introduction of 11 other new small habitable-zone candidate planets mark another milestone in the journey to finding another “Earth.”

The newly discovered Kepler-452b is the smallest planet to date discovered orbiting in the habitable zone — the area around a star where liquid water could pool on the surface of an orbiting planet — of a G2-type star, like our sun. The confirmation of Kepler-452b brings the total number of confirmed planets to 1,030.

NASA to announce new discoveries by it’s planet seeking Kepler Space Telescope Thursday, July 23rd

NASA - National Aeronautics and Space AdministrationWashington, D.C. – NASA will host a news teleconference at 9:00am PDT (noon EDT) Thursday, July 23rd, to announce new discoveries made by its planet-hunting mission, the Kepler Space Telescope.

The first exoplanet orbiting another star like our sun was discovered in 1995. Exoplanets, especially small Earth-size worlds, belonged within the realm of science fiction just 21 years ago. Today, and thousands of discoveries later, astronomers are on the cusp of finding something people have dreamed about for thousands of years — another Earth.

NASA’s Hubble Space Telescope reveals chaotic wobbling dance of Pluto’s Moons Nix and Hydra

 

Written by Felicia Chou
NASA Headquarters

NASA - National Aeronautics and Space AdministrationWashington, D.C. – If you lived on one of Pluto’s moons, you might have a hard time determining when, or from which direction, the sun will rise each day. Comprehensive analysis of data from NASA’s Hubble Space Telescope shows that two of Pluto’s moons, Nix and Hydra, wobble unpredictably.

“Hubble has provided a new view of Pluto and its moons revealing a cosmic dance with a chaotic rhythm,” said John Grunsfeld, associate administrator of NASA’s Science Mission Directorate in Washington. “When the New Horizons spacecraft flies through the Pluto system in July we’ll get a chance to see what these moons look like up close and personal.”

NASA to investigate Climate change with Airborne Campaigns

 

Written by Alan Buis
NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, CA – Five new NASA airborne field campaigns, including one managed by NASA’s Jet Propulsion Laboratory, Pasadena, California, will take to the skies starting in 2015 to investigate how long-range air pollution, warming ocean waters and fires in Africa affect our climate.

These studies into several incompletely understood Earth system processes were competitively selected as part of NASA’s Earth Venture-class projects. Each project is funded at a total cost of no more than $30 million over five years. This funding includes initial development, field campaigns and analysis of data.

NASA study looks into reduction of Bright Clumps in Saturn’s Ring

 

Written by Preston Dyches
NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, CA – Compared to the age of the solar system — about four-and-a-half billion years — a couple of decades are next to nothing. Some planetary locales change little over many millions of years, so for scientists who study the planets, any object that evolves on such a short interval makes for a tempting target for study. And so it is with the ever-changing rings of Saturn.

Case in point: Saturn’s narrow, chaotic and clumpy F ring. A recent NASA-funded study compared the F ring’s appearance in six years of observations by the Cassini mission to its appearance during the Saturn flybys of NASA’s Voyager mission, 30 years earlier.

Cassini spied just as many regular, faint clumps in Saturn's narrow F ring, like those pictured here, as Voyager did, but it saw hardly any of the long, bright clumps that were common in Voyager images. (NASA/JPL-Caltech/SSI)

NASA’s Global Hawk research aircraft finishes Climate Change study

 

Written by Rachel Hoover
NASA Ames Research Center

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.
