Tarantula Nebula spins web of mystery in Spitzer image

Tarantula Nebula spins web of mystery in Spitzer image The Tarantula Nebula, seen in this image by the Spitzer Space Telescope, was one of the first targets studied by the infrared observatory after its launch in 2003, and the telescope has revisited it many times since. Now that Spitzer is set to be retired on […]

Stalking Starlink’s ‘DarkSat’

Stalking Starlink’s ‘DarkSat’ By now, you’ve no doubt heard of (or seen) Starlink. SpaceX’s mega-satellite constellation has become a permanent fixture in our skies as of late, with several routine passes on any given week. But have you seen the supposed ‘black sheep’ of the flock, DarkSat? The post Stalking Starlink’s ‘DarkSat’ appeared first on […]

How Earth climate models help picture life on unimaginable worlds

How Earth climate models help picture life on unimaginable worlds In a generic brick building on the northwestern edge of NASA’s Goddard Space Flight Center campus in Greenbelt, Maryland, thousands of computers packed in racks the size of vending machines hum in a deafening chorus of data crunching. Day and night, they spit out 7 […]

NASA’s Kepler witnesses vampire star system undergoing super-outburst

NASA’s Kepler witnesses vampire star system undergoing super-outburst NASA’s Kepler spacecraft was designed to find exoplanets by looking for stars that dim as a planet crosses the star’s face. Fortuitously, the same design makes it ideal for spotting other astronomical transients—objects that brighten or dim over time. A new search of Kepler archival data has […]

NESSI emerges as new tool for exoplanet atmospheres

NESSI emerges as new tool for exoplanet atmospheres The darkness surrounding the Hale Telescope breaks with a sliver of blue sky as the dome begins to open, screeching with metallic, sci-fi-like sounds atop San Diego County’s Palomar Mountain. The historic observatory smells of the oil pumped in to support the bearings that make this giant […]

Simulations reveal galaxy clusters details

Simulations reveal galaxy clusters details Inspired by the science fiction of the spacefaring Romulans of Star Trek, astrophysicists have used XSEDE-allocated supercomputers to develop cosmological computer simulations called RomulusC, where the ‘C’ stands for galaxy cluster. With a focus on black hole physics, RomulusC has produced some of the highest resolution simulations ever of galaxy […]

This is Probably Sandstone Layers on Mars. Absolutely Beautiful

This is Probably Sandstone Layers on Mars. Absolutely Beautiful NASA’s Mars Reconnaissance Orbiter (MRO) has been in orbit around Mars for almost 14 years. It carries a variety of instruments with it, including the Compact Reconnaissance Imaging Spectrometer for Mars (CRISM) instrument. That instrument has collected thousands of images of Mars.
