Study-Helps-Explain-Comet-Composition

New research from NASA’s Jet Propulsion Laboratory used a cryostat instrument, nicknamed “Himalaya,” to study the icy conditions under which comets form. Astronomers tinkering with ice and organics in the lab may have discovered why comets are encased in a hard, outer crust. Using an icebox-like instrument nicknamed Himalaya, the researchers show that fluffy ice […]

Mars Reconnaissance Orbiter Completes 40,000 Mars Orbits

Launched in 2005, the Mars Reconnaissance Orbiter has now orbited the Red Planet more than 40,000 times. NASA’s Mars Reconnaissance Orbiter passed a mission milestone of 40,000 orbits on February 7, 2015, in its ninth year of returning information about the atmosphere, surface and subsurface of Mars, from equatorial to polar latitudes. The mission’s potent […]

Asteroid 2004 BL86 and Its Small Moon

As asteroid 2004 BL86 made its way past Earth yesterday, scientists were able to better measure the asteroid’s size, rotation and location and detected a tiny moon orbiting the asteroid. This “movie” of the asteroid was generated from radar data collected on that date by NASA’s Deep Space Network antenna at Goldstone, California. Twenty individual […]

Greenland's Ice Layers Mapped in 3D

Using ice-penetrating radar data and data collected from earlier airborne campaigns, scientists have built the first-ever comprehensive map of layers deep inside the Greenland Ice Sheet. Peering into the thousands of frozen layers inside Greenland’s ice sheet is like looking back in time. Each layer provides a record of what Earth’s climate was like at […]

LBTI Views a Dusty Star

The Large Binocular Telescope Interferometer has completed its first study of dust in the “habitable zone” around a star, opening a new door to finding planets like Earth. The findings will help in the design of future space missions that have the goal of taking pictures of planets similar to Earth, called exo-Earths. “Kepler told […]
