Astronomers using NASA’s Hubble Space Telescope and Europe’s Herschel Space Observatory have pieced together the evolutionary sequence of compact elliptical galaxies that erupted and burned out early in [...]

NASA's Chandra Observatory Catches Giant Black Hole Rejecting Material

Astronomers using NASA’s Chandra X-ray Observatory have taken a major step in explaining why material around the giant black hole at the center of the Milky Way Galaxy is extraordinarily faint in X-rays. This discovery holds important implications for understanding black holes.

For the first time since exoplanets, or planets around stars other than the sun, were discovered almost 20 years ago, X-ray observations have detected an exoplanet passing in front of its parent star.

Coming soon to a region of space near you: comet ISON, which is expected to put on a spectacular show toward the end of the year. Currently, ISON is about 258 million miles from the Sun, between the orbits of Jupiter and Mars. Its tail already stretches out more than three-quarters of [...]

SOFIA Observations Reveal a Surprise in Massive Star Formation

Figures 1a and 1b show the G35 protostar at wavelengths of 31 and 37 microns taken by the FORCAST instrument on the SOFIA observatory’s infrared telescope in 2011. (Zhang et al. 2013, Astrophysical Journal)

WASHINGTON — Researchers using the airborne Stratospheric Observatory for Infrared Astronomy (SOFIA) have captured the most detailed mid-infrared images yet of [...]

Planck Mission Brings Universe into Sharp Focus

This map shows the oldest light in our universe, as detected with the greatest precision yet by the Planck mission. The ancient light, called the cosmic microwave background, was imprinted on the sky when the universe was 370,000 years old. It shows tiny temperature fluctuations that correspond to regions of slightly different densities, representing [...]

PASADENA, Calif. — Astronomers using NASA’s Spitzer and Hubble space telescopes have probed the stormy atmosphere of a brown dwarf, creating the most detailed “weather map” yet for this class of cool, star-like orbs. The forecast shows wind-driven, planet-sized clouds enshrouding these strange [...]

Proposals Sought for Two NASA Space Telescopes
