Precocious supermassive black holes challenge theories

NASA's Chandra X-ray Observatory has obtained definitive evidence that a distant quasar formed less than a billion years after the big bang contains a fully-grown supermassive black hole generating energy at the rate of twenty trillion suns. The existence of such massive black holes at this early epoch of the Universe challenges theories of the formation of galaxies and supermassive black holes...

Kennedy Space Center device being tested to help keep military equipment in top form...

When looking at a massive launch vehicle or aircraft, it’s hard to imagine that a problem with one tiny wire could paralyze its performance. To reduce processing delays and ensure safe and sound performance, Kennedy Space Center technology experts invented the Standing Wave Reflectometer (SWR).

Hubble Tracks Asteroid's Sky Trek

While analyzing NASA Hubble Space Telescope images of the Sagittarius dwarf irregular galaxy (SagDIG), an international team of astronomers led by Simone Marchi, Yazan Momany, and Luigi Bedin were surprised to see the trail of a faint asteroid that had drifted across the field of view during the exposures. The trail is seen as a series of 13 arcs on the right in this August 2003 Advanced Camera for Surveys image.

VLA Study Offers Clue to Galaxy Formation

Astronomers using the National Science Foundation's Very Large Array (VLA) radio telescope to study the most distant known quasar have found a tantalizing clue that may answer a longstanding cosmic chicken-and-egg question: which came first, supermassive black holes or giant galaxies?

Cassini's Radar Shows Titan's Young Active Surface

"Unveiling Titan is like reading a mystery novel," said Dr. Charles Elachi, director of NASA's Jet Propulsion Laboratory, Pasadena, Calif., and team leader for the radar instrument on Cassini. "Each time you flip the page you learn something new, but you don't know the whole story until you've read the whole book. The story of Titan is unfolding right before our eyes, and what we are seeing is intriguing."
