The galaxy cluster, called IDCS J1426.5+3508 (IDCS 1426 for short), is so far away that the light detected is from when the universe was roughly a quarter of its current age. It is the most massive galaxy cluster detected at such an early age. ![]() Astronomers have made the most detailed study yet of an extremely massive young galaxy cluster using three of NASA’s Great Observatories.

NASA’s Wide-field Infrared Survey Explorer (WISE) spacecraft continues hunting asteroids long past its planned lifetimeWritten by DC Agle
These measurements include wavelengths that are difficult or impossible to detect directly from the ground. NEOWISE is one of 54 ongoing projects supported by the NEO Observations Program in fiscal year 2015. NASA-funded survey projects have found 98 percent of the known catalogue of more than 13,000 NEOs. NASA-funded surveys are currently finding NEOs at a rate of about 1,500 per year. ![]() This artist’s concept shows the Wide-field Infrared Survey Explorer, or WISE spacecraft, in its orbit around Earth.

NASA’s Mars Rover Curiosity data helps scientists confirm Ancient Lakes on MarsWritten by Whitney Clavin
Using data from the Curiosity rover, the team has determined that, long ago, water helped deposit sediment into Gale Crater, where the rover landed more than three years ago. The sediment deposited as layers that formed the foundation for Mount Sharp, the mountain found in the middle of the crater today. ![]() A view from the “Kimberley” formation on Mars taken by NASA’s Curiosity rover.

NASA’s Cassini spacecraft to make final pass of Saturn’s moon DioneWritten by Preston Dyches
Cassini’s closest approach, within 295 miles (474 kilometers) of Dione’s surface, will occur at 11:33am PDT (2:33pm EDT). Mission controllers expect fresh images to begin arriving on Earth within a couple of days following the encounter. Cassini scientists have a bevy of investigations planned for Dione. Gravity-science data from the flyby will improve scientists’ knowledge of the moon’s internal structure and allow comparisons to Saturn’s other moons. ![]() A view of Saturn’s moon Dione captured by NASA’s Cassini spacecraft during a close flyby on June 16, 2015.

NASA’s Kepler Space Telescope searches for another EarthWritten by Whitney Clavin
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. ![]() A newly discovered exoplanet, Kepler-452b, comes the closest of any found so far to matching our Earth-sun system. A newly discovered exoplanet, Kepler-452b: from left, Kepler-22b, Kepler-69c, the just announced Kepler-452b, Kepler-62f and Kepler-186f. Last in line is Earth itself.

NASA’s Mars Curiosity rover finds Silica in Bedrock on MarsWritten by Whitney Clavin
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.” ![]() A rock fragment dubbed “Lamoose” is shown in this picture taken by the Mars Hand Lens Imager (MAHLI) on NASA’s Curiosity rover.
