Festive nebulae light up Milky Way Galaxy satellite

Festive nebulae light up Milky Way Galaxy satellite

The sheer observing power of the NASA/ESA Hubble Space Telescope is rarely better illustrated than in an image such as this. This glowing pink nebula, named NGC 248, is located in the Small Magellanic Cloud, just under 200 000 light-years away and yet can still be seen in great detail. Our home galaxy, the Milky […]

NASA to Launch Fleet of Hurricane-Tracking SmallSats

NASA to Launch Fleet of Hurricane-Tracking SmallSats

NASA is set to launch its first Earth science small satellite constellation, which will help improve hurricane intensity, track and storm surge forecasts, on Dec. 12 from Cape Canaveral Air Force Station in Florida. The Cyclone Global Navigation Satellite System (CYGNSS) hurricane mission will measure previously unknown details crucial to accurately understanding the formation and […]

Curiosity Mars Rover Checks Odd-looking Iron Meteorite

Curiosity Mars Rover Checks Odd-looking Iron Meteorite

Curiosity Mars Rover Checks Odd-looking Iron Meteorite The dark, golf-ball-size object in this composite, colorized view from the ChemCam instrument on NASA’s Curiosity Mars rover is a nickel-iron meteorite, as confirmed by analysis using laser pulses from ChemCam on Oct. 30, 2016. The grid of bright spots on the rock resulted from the laser pulses. […]

NASA Moon Mission Shares Insights into Giant Impacts

NASA Moon Mission Shares Insights into Giant Impacts

Fast Facts: › Orientale basin is a giant, ringed impact crater on Earth’s moon. › Until now, how impact craters with rings form had not been well understood. › Scientists have reconstructed Orientale’s formation using data from NASA’s GRAIL mission. New results from NASA’s Gravity Recovery and Interior Laboratory (GRAIL) mission are providing insights into […]

Cloudy Nights, Sunny Days on Distant Hot Jupiters

Cloudy Nights, Sunny Days on Distant Hot Jupiters

Fast Facts: › Hot Jupiters are very warm planets outside our solar system that orbit their stars tightly › A new study finds that the compositions of clouds on hot Jupiters depend on the planets’ temperatures › The results also suggest that clouds on hot Jupiters are not evenly distributed The weather forecast for faraway, […]

Spacecraft ‘Nuclear Batteries’ Could Get a Boost from New Materials

Spacecraft ‘Nuclear Batteries’ Could Get a Boost from New Materials

No extension cord is long enough to reach another planet, and there’s no spacecraft charging station along the way. That’s why researchers are hard at work on ways to make spacecraft power systems more efficient, resilient and long-lasting. “NASA needs reliable long-term power systems to advance exploration of the solar system,” said Jean-Pierre Fleurial, supervisor […]

Observable Universe contains ten times more galaxies than previously thought

Observable Universe contains ten times more galaxies than previously thought

Astronomers using data from the NASA/ESA Hubble Space Telescopes and other telescopes have performed an accurate census of the number of galaxies in the Universe. The group came to the surprising conclusion that there are at least 10 times as many galaxies in the observable Universe as previously thought. The results have clear implications for […]
