Washington, D.C. – Two’s company, but three might not always be a crowd — at least in space.
Astronomers using NASA’s Hubble Space Telescope, and a trick of nature, have confirmed the existence of a planet orbiting two stars in the system OGLE-2007-BLG-349, located 8,000 light-years away towards the center of our galaxy.
The planet orbits roughly 300 million miles from the stellar duo, about the distance from the asteroid belt to our sun. It completes an orbit around both stars roughly every seven years. The two red dwarf stars are a mere 7 million miles apart, or 14 times the diameter of the moon’s orbit around Earth.
NASA, Japan Aerospace Exploration Agency partner to increase research abilities on International Space Station
Washington, D.C. – A new program for research cooperation on the International Space Station will enable JAXA (Japan Aerospace Exploration Agency) and NASA to encourage researchers and entities from both countries to mutually utilize experiment hardware between the U.S. and Japanese Experiment Module (JEM, or Kibo, which means “Hope” in Japanese).
The Japan-U.S. Open Platform Partnership Program was announced by the governments of the U.S. and Japan in December 2015, and will run through at least 2024.

Pasadena, CA – The puzzling appearance of an ice cloud seemingly out of thin air has prompted NASA scientists to suggest that a different process than previously thought — possibly similar to one seen over Earth’s poles — could be forming clouds on Saturn’s moon Titan.
Located in Titan’s stratosphere, the cloud is made of a compound of carbon and nitrogen known as dicyanoacetylene (C4N2), an ingredient in the chemical cocktail that colors the giant moon’s hazy, brownish-orange atmosphere.
NASA’s Marshall Space Flight Center
Huntsville, AL – The largest rocket stage in the world is coming together piece by piece at NASA’s Michoud Assembly Facility in New Orleans, LA. Large elements for NASA’s Space Launch System are in production and will be joined together to create the rocket’s 212-foot-tall core stage, the backbone of the SLS rocket.
Why is NASA building the world’s most powerful rocket? Because SLS is ready to support both near-term missions in the proving ground around the moon starting in 2018, while at the same time being capable of carrying the very large hardware like landers, habitats and other supplies and equipment needed to explore Mars and other deep space destinations in the 2030s and beyond.

Pasadena, CA – After more than 12 years studying Saturn, its rings and moons, NASA’s Cassini spacecraft has entered the final year of its epic voyage. The conclusion of the historic scientific odyssey is planned for September 2017, but not before the spacecraft completes a daring two-part endgame.
Beginning on November 30th, Cassini’s orbit will send the spacecraft just past the outer edge of the main rings. These orbits, a series of 20, are called the F-ring orbits. During these weekly orbits, Cassini will approach to within 4,850 miles (7,800 kilometers) of the center of the narrow F ring, with its peculiar kinked and braided structure.

Pasadena, CA – Lakes and snowmelt-fed streams on Mars formed much later than previously thought possible, according to new findings using data primarily from NASA’s Mars Reconnaissance Orbiter.
The recently discovered lakes and streams appeared roughly a billion years after a well-documented, earlier era of wet conditions on ancient Mars. These results provide insight into the climate history of the Red Planet and suggest the surface conditions at this later time may also have been suitable for microbial life.
NASA’s Wide-field Infrared Survey Explorer (WISE) data gives new insights into Black Holes devouring Stars
Written by Elizabeth Landau
Pasadena, CA – Supermassive black holes, with their immense gravitational pull, are notoriously good at clearing out their immediate surroundings by eating nearby objects. When a star passes within a certain distance of a black hole, the stellar material gets stretched and compressed — or “spaghettified” — as the black hole swallows it.
A black hole destroying a star, an event astronomers call “stellar tidal disruption,” releases an enormous amount of energy, brightening the surroundings in an event called a flare. In recent years, a few dozen such flares have been discovered, but they are not well understood.
Washington, D.C. – In June 2015, when the cameras on NASA’s approaching New Horizons spacecraft first spotted the large reddish polar region on Pluto’s largest moon, Charon, mission scientists knew two things: they’d never seen anything like it elsewhere in our solar system, and they couldn’t wait to get the story behind it.
Over the past year, after analyzing the images and other data that New Horizons has sent back from its historic July 2015 flight through the Pluto system, the scientists think they’ve solved the mystery.

Huntsville, AL – Scientists using NASA’s Chandra X-ray Observatory have made the first detections of X-rays from Pluto. These observations offer new insight into the space environment surrounding the largest and best-known object in the solar system’s outermost regions.
While NASA’s New Horizons spacecraft was speeding toward and beyond Pluto, Chandra was aimed several times on the dwarf planet and its moons, gathering data on Pluto that the missions could compare after the flyby. Each time Chandra pointed at Pluto – four times in all, from February 2014 through August 2015 – it detected low-energy X-rays from the small planet.

Pasadena, CA – A NASA airborne mission designed to transform our understanding of Earth’s valuable and ecologically sensitive coral reefs has set up shop in Australia for a two-month investigation of the Great Barrier Reef, the world’s largest reef ecosystem.
At a media briefing today at Cairns Airport in North Queensland, Australia, scientists from NASA’s COral Reef Airborne Laboratory (CORAL) mission and their Australian collaborators discussed the mission’s objectives and the new insights they expect to glean into the present condition of the Great Barrier Reef and the function of reef systems worldwide.
