Washington, D.C. – Flowing ice and a surprising extended haze are among the newest discoveries from NASA’s New Horizons mission, which reveal distant Pluto to be an icy world of wonders.
“We knew that a mission to Pluto would bring some surprises, and now — 10 days after closest approach — we can say that our expectation has been more than surpassed,” said John Grunsfeld, NASA’s associate administrator for the Science Mission Directorate. “With flowing ices, exotic surface chemistry, mountain ranges, and vast haze, Pluto is showing a diversity of planetary geology that is truly thrilling.”
Nashville, TN – After going ahead in the eighth, Nashville allowed three runs in the ninth and dropped the series finale to the New Orleans Zephyrs at First Tennessee Park on Monday night, 7-5.
Despite collecting 16 hits, three shy of a season high, the Sounds left 12 on base. The loss marked the fourth time Nashville has been swept this season. In addition, the 3:47 game time was the longest nine-inning contest the Sounds have played in 2015.
Washington, D.C. – NASA’s New Horizons mission has found evidence of exotic ices flowing across Pluto’s surface, at the left edge of its bright heart-shaped area. New close-up images from the spacecraft’s Long-Range Reconnaissance Imager (LORRI) reveal signs of recent geologic activity, something scientists hoped to find but didn’t expect.
“We’ve only seen surfaces like this on active worlds like Earth and Mars,” said mission co-investigator John Spencer of SwRI. “I’m really smiling.”

Pasadena, CA – The discovery of a super-Earth-sized planet orbiting a sun-like star brings us closer than ever to finding a twin of our own watery world. But NASA’s Kepler space telescope has captured evidence of other potentially habitable planets amid the sea of stars in the Milky Way galaxy.
To take a brief tour of the more prominent contenders, it helps to zero in on the “habitable zone” around their stars. This is the band of congenial temperatures for planetary orbits — not too close and not too far.

Pasadena, CA – Approaching the third anniversary of its landing on Mars, NASA’s Curiosity Mars rover has found a target unlike anything it has studied before — bedrock with surprisingly high levels of silica. Silica is a rock-forming compound containing silicon and oxygen, commonly found on Earth as quartz.
This area lies just downhill from a geological contact zone the rover has been studying near “Marias Pass” on lower Mount Sharp.
In fact, the Curiosity team decided to back up the rover 46 meters (151 feet) from the geological contact zone to investigate the high-silica target dubbed “Elk.”
NASA’s Kepler Space Telescope finds Earth size planet around a star like our sun in the Habitable Zone

Pasadena, 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.

Huntsville, AL – A fast-moving pulsar appears to have punched a hole in a disk of gas around its companion star and launched a fragment of the disk outward at a speed of about 4 million miles per hour. NASA’s Chandra X-ray Observatory is tracking this cosmic clump, which appears to be picking up speed as it moves out.
The double star system PSR B1259-63/LS 2883 – or B1259 for short – contains a star about 30 times as massive as the Sun and a pulsar, an ultra-dense neutron star left behind when an even more massive star underwent a supernova explosion.

Washington, 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.
Washington, D.C. – Astronauts on the International Space Station give up many pleasures to take those giant leaps in the name of science. They leave behind fresh vegetables, relaxing hot showers, warm sunshine, gently misting rain, and much more.
One of the things astronauts say they miss most is a good cup of coffee. How would YOU like to start your morning sucking freeze dried coffee through a straw from a sealed plastic bag?
Good news for astronauts: Morning Joe recently got an upgrade. On April 20th, SpaceX delivered to the space station a new microgravity coffee machine named “ISSpresso.”

Pasadena, CA – NASA’s Dawn spacecraft is using its ion propulsion system to descend to its third mapping orbit at Ceres, and all systems are operating well. The spiral maneuvering over the next five weeks will take the spacecraft to an altitude of about 900 miles (less than 1,500 kilometers) above the dwarf planet.
The spacecraft experienced a discrepancy in its expected orientation on June 30, triggering a safe mode. Engineers traced this anomaly to the mechanical gimbal system that swivels ion engine #3 to help control the spacecraft’s orientation during ion-thrusting. Dawn has three ion engines and uses only one at a time.
