WASHINGTON — Two of NASA’s great observatories, the Spitzer and Hubble space telescopes, have teamed up to uncover a mysterious infant star that behaves like a strobe light. Every 25.34 days, the object, designated LRLL 54361, unleashes a burst of light. Although a similar phenomenon has been observed in two other young stellar objects, this is the most powerful […]

NASA to Launch Ocean Wind Monitor to Space Station
WASHINGTON — In a clever reuse of hardware originally built to test parts of NASA’s QuikScat satellite, the agency will launch the ISS-RapidScat instrument to the International Space Station in 2014 to measure ocean-surface wind speed and direction. The ISS-RapidScat instrument will help improve weather forecasts, including hurricane monitoring, and understanding of how ocean-atmosphere interactions […]

NASA Telescope Observes How Sun Stores and Releases Energy
WASHINGTON — A NASA suborbital telescope has given scientists the first clear evidence of energy transfer from the sun’s magnetic field to the solar atmosphere or corona. This process, known as solar braiding, has been theorized by researchers, but remained unobserved until now. Researchers were able to witness this phenomenon in the highest resolution images […]
Martian Crater Once May Have Held Groundwater-Fed Lake
PASADENA, Calif. — A NASA spacecraft is providing new evidence of a wet underground environment on Mars that adds to an increasingly complex picture of the Red Planet’s early evolution. The new information comes from researchers analyzing spectrometer data from NASA’s Mars Reconnaissance Orbiter (MRO), which looked down on the floor of McLaughlin Crater. The […]
