The Brightest Supernova Ever Seen was Caused by a White Dwarf Spiraling into a Massive Star Super-luminous supernovae are the brightest explosions in the Universe. In just a few months, a super-luminous supernova can release as much energy as our Sun will in its entire lifespan. And at its peak, it can be as bright […]
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 […]

The Apollo 1 Fire: Excerpt from “Eight Years to the Moon” Editor’s note: Today marks the 53rd anniversary of the Apollo 1 fire that killed three astronauts during a routine test on the launchpad. The test was a dress rehearsal for the Apollo 1 crew — Gus Grissom, Ed White and Roger Chaffee. The goal […]
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 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 […]

In a rare sighting, astronomers observe burst of activity as a massive star forms Here on Earth, we pay quite a lot of attention to the sun. It’s visible to us, after all, and central to our lives. But it is only one of the billions of stars in our galaxy, the Milky Way. It’s […]
China Releases New Pictures From the Surface of the Moon China’s Chang’e-4 mission just released a trove of data collected by the lander and rover during its year-long exploration of the far side of the Moon.

Giant Planets Could Form Around Tiny Stars in Just a Few Thousand Years A new study has shown how gas giants (like Proxima c) can exist around Red Dwarf suns, the most common type of star in the Universe The post Giant Planets Could Form Around Tiny Stars in Just a Few Thousand Years appeared […]
OSIRIS-REx Flew 620 Meters Above its Landing Site. Confirms that it’s a Boulder-Strewn Nightmare, Just Like the Rest of Bennu NASA’s OSIRIS-REx spacecraft reached its target, asteroid Bennu (101955 Bennu), on December 3rd, 2018. Since then, the spacecraft has been examining the asteroid’s surface, looking for a suitable landing spot to collect a sample. The […]
A Glitch Caused Curiosity to Freeze in Place. But It’s Better Now NASA’s Curiosity Mars rover experienced a technical glitch in its stored memory last week, causing it to temporarily lose its sense of direction and freeze in its tracks. But the talented rover repair team back on Earth enabled a fix, and Curiosity is […]
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 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 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 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. CRISM’s main purpose is […]
