NASA’s Kepler Telescope Discovers First Earth-Size Planet in ‘Habitable Zone’

by William W.on April 17, 2014
Using NASA’s Kepler Space Telescope, astronomers have discovered the first Earth-size planet orbiting a star in the “habitable zone” — the range of distance from a star where liquid water might pool on the surface of an orbiting planet. The discovery of Kepler-186f confirms that planets the size of Earth exist in the habitable zone [...]

SpaceX Launch of NASA Cargo to Space Station Set for Friday, Spacewalk Wednesday

by William W.on April 17, 2014
NASA and SpaceX are targeting a 3:25 p.m. EDT launch on Friday, April 18, of SpaceX’s third cargo resupply mission to the International Space Station from Cape Canaveral Air Force Station in Florida. NASA Television coverage will begin at 2:15 p.m. The company’s April 14 launch to the orbiting laboratory was scrubbed due to a helium leak in the [...]

This concept image shows an astronaut preparing to take samples from the captured asteroid after it has been relocated to a stable orbit in the Earth-moon system. Hundreds of rings are affixed to the asteroid capture bag, helping the astronaut carefully navigate the surface.

NASA Solicits Proposals for Asteroid Redirect Mission

by Chrison March 24, 2014
Much like NASA did for ideas about how to best make use of the Kepler spacecraft after its reaction wheel failure earlier last year, NASA is now asking for proposals for advanced technology concepts development for the Asteroid Redirect Mission. The Asteroid Redirect Mission would use a small unmanned spacecraft to capture a near-Earth asteroid [...]

Birth of the Universe detected by scientists

by William W.on March 17, 2014
Astronomers are announcing today that they have acquired the first direct evidence that gravitational waves rippled through our infant universe during an explosive period of growth called inflation. This is the strongest confirmation yet of cosmic inflation theories, which say the universe expanded by 100 trillion trillion times, in less than the blink of an [...]

Space Station Crew Returns to Earth, Lands Safely in Kazakhstan

by William W.on March 11, 2014
Three crew members from the International Space Station returned to Earth Mondayafter 166 days in space, during which they made 2,656 orbits around the planet and traveled almost 70.5 million miles Expedition 38 crew members Michael Hopkins of NASA, and Oleg Kotov and Sergey Ryazanskiy of the Russian Federal Space Agency (Roscosmos) touched down southeast of [...]

NASA’s WISE Survey Finds Thousands of New Stars, But No ‘Planet X’

by William W.on March 7, 2014
After searching hundreds of millions of objects across our sky, NASA’s Wide-Field Infrared Survey Explorer (WISE) has turned up no evidence of the hypothesized celestial body in our solar system commonly dubbed “Planet X.” Researchers previously had theorized about the existence of this large, but unseen celestial body, suspected to lie somewhere beyond the orbit [...]

NASA Radar Demonstrates Ability to Foresee Sinkholes

by William W.on March 6, 2014
New analyses of NASA airborne radar data collected in 2012 reveal the radar detected indications of a huge sinkhole before it collapsed and forced evacuations near Bayou Corne, La. that year. The findings suggest such radar data, if collected routinely from airborne systems or satellites, could at least in some cases foresee sinkholes before they [...]

NASA: Warm Rivers Play Role in Arctic Sea Ice Melt

by William W.on March 6, 2014
The heat from warm river waters draining into the Arctic Ocean is contributing to the melting of Arctic sea ice each summer, a new NASA study finds. A research team led by Son Nghiem of NASA’s Jet Propulsion Laboratory in Pasadena, Calif., used satellite data to measure the surface temperature of the waters discharging from [...]

NASA has discovered 715 New Worlds

by William W.on February 26, 2014
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 [...]

NASA scientists unwrap mystery of how stars explode

by William W.on February 19, 2014
One of the biggest mysteries in astronomy, how stars blow up in supernova explosions, finally is being unraveled with the help of NASA’s Nuclear Spectroscopic Telescope Array (NuSTAR). The high-energy X-ray observatory has created the first map of radioactive material in a supernova remnant. The results, from a remnant named Cassiopeia A (Cas A), reveal [...]

Mars Rover Heads Uphill After Solving ‘Doughnut’ Riddle

by William W.on February 15, 2014
Researchers have determined the now-infamous Martian rock resembling a jelly doughnut, dubbed Pinnacle Island, is a piece of a larger rock broken and moved by the wheel of NASA’s Mars Exploration Rover Opportunity in early January. Only about 1.5 inches wide (4 centimeters), the white-rimmed, red-centered rock caused a stir last month when it appeared [...]

NASAs Mars orbiter sees signs of seasonal water flow on Mars surface

by William W.on February 11, 2014
NASA spacecraft orbiting Mars have returned clues for understanding seasonal features that are the strongest indication of possible liquid water that may exist today on the Red Planet. The features are dark, finger-like markings that advance down some Martian slopes when temperatures rise. The new clues include corresponding seasonal changes in iron minerals on the [...]

NASAs Mars Curiosity rover has taken the first picture of Earth and our Moon from the surface of the red planet

by William W.on February 10, 2014
This view of the twilight sky and Martian horizon taken by NASA’s Curiosity Mars rover includes Earth as the brightest point of light in the night sky. Earth is a little left of center in the image, and our moon is just below Earth. Researchers used the left eye camera of Curiosity’s Mast Camera (Mastcam) [...]

NASA spots an incredibly wobbly Super Neptune planet, Kepler-413b

by William W.on February 4, 2014
Imagine living on a planet with seasons so erratic you would hardly know whether to wear Bermuda shorts or a heavy overcoat. That is the situation on a weird, wobbly world found by NASA’s planet-hunting Kepler space telescope. The planet, designated Kepler-413b, precesses, or wobbles, wildly on its spin axis, much like a child’s top. [...]

Hubble space telescope helps solve mystery of how the most massive galaxies were formed

by William W.on January 29, 2014
Astronomers using NASA’s Hubble Space Telescope and Europe’s Herschel Space Observatory have pieced together the evolutionary sequence of compact elliptical galaxies that erupted and burned out early in the history of the universe. Enabled by Hubble’s infrared imaging capabilities, astronomers have assembled for the first time a representative spectroscopic sampling of ultra-compact, burned-out elliptical galaxies [...]
