Lonely Supernova Likely Exiled by Merging Black Holes

Elliptical galaxies with dark, wispy dust lanes suggest galaxy mergers. The combination of two supermassive black holes at their center could have cast out pairs of older stars that later exploded into supernovae without host galaxies.Credit: NASA, ESA, and R. Foley (University of Illinois) Isolated supernovae, exploding alone in the empty space between galaxies, may […]

New NASA Satellites Could Help Improve Hurricane Warnings

Artist’s concept of one of the eight Cyclone Global Navigation Satellite System satellites deployed in space above a hurricane.Credit: NASA Ten years after Hurricane Katrina ravaged the city of New Orleans and surrounding areas, NASA is building an innovative storm-monitoring system that could make significant improvements in storm monitoring and warnings. Eight “microsatellites,” each slightly […]

Sampling Enceladus: Is Earth Ready for Pieces of Saturn Moon's Plumes?

The plumes of Saturn’s moon Enceladus, as seen by NASA’s Cassini probe in 2009.Credit: NASA/JPL/SPACE SCIENCE INSTITUTE Many astrobiologists are champing at the bit to bring back samples from Saturn’s ocean-harboring moon Enceladus, but others say it may be best to exercise a little patience. In 2005, NASA’s Cassini spacecraft discovered that geysers blast from […]

NASA Crashes Plane to Test Emergency Beacons (Video)

NASA sent a small airplane plummeting to Earth today (Aug. 26), for safety’s sake. Scientists and engineers at the space agency’s Langley Research Center in Virginia dropped a Cessna 172 from a height of 100 feet (30 meters), in a crash test that was captured on video . The plane hit belly first, then flopped […]

New NASA Model Maps Sea Level Rise Like Never Before (Video)

A new NASA model is showing just how fast sea levels are rising around the world as a result of climate change. At a news conference today (Aug. 26), NASA officials described a new computer visualization of sea level change incorporating data collected by satellites since 1992 — it reveals that sea levels are rising […]

22 Years of Sea Level Rise Measured From Space | Video

Global ocean levels have risen about 6 cm (2.3 in) over the past two decades, matching models consistent with human-induced climate change. NASA monitors sea heights and other parameters with the Jason satellite series. Jet Propulsion Laboratory oceanographer Josh Willis explains the data. Credit: NASA/JPL To source
