Astronomers Link Black-Hole Wind to a Galactic Gush of Star-Forming Gas

A newly published study is the first to directly connect a galaxy’s actively ‘feeding’ black hole to features found at much larger physical scales, revealing that it’s responsible for blowing star-forming gas out of the galaxy’s central regions. By combining observations from the Japan-led Suzaku X-ray satellite and the European Space Agency’s infrared Herschel Space […]

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 […]

SDO Views Giant Filament on the Sun

This new image from NASA’s Solar Dynamics Observatory shows a giant filament on the Sun. A dark line snaked across the lower half of the sun on February 10, 2015, as seen in this image from NASA’s Solar Dynamics Observatory, or SDO. SDO shows colder material as dark and hotter material as light, so the […]

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 […]

Citizen Scientists Find Mystery Objects in Space

Using data from NASA’s Spitzer Space Telescope, volunteers discovered a new way to detect the early stages of massive star formation. Sometimes it takes a village to find new and unusual objects in space. Volunteers scanning tens of thousands of starry images from NASA’s Spitzer Space Telescope, using the Web-based Milky Way Project, recently stumbled […]

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 […]
