NASA’s InSight Mars lander took this final selfie on April 24, 2022, the 1,211th Martian day, or sol, of the mission. The lander is covered with far more dust than it was in its first selfie, taken in December 2018, not long after landing – or in its second selfie, composed of images taken in March and April 2019. The arm now needs to move several time...
This Hubble Space Telescope image shows a section of the spiral galaxy nicknamed the Needle’s Eye – an appropriately diminutive name for a dwarf spiral galaxy. The Needle’s Eye, also known as NGC 247 and Caldwell 62, is located about 11 million light-years away in the Sculptor Group – the closest group of galaxies to our own (the Local Group). The galaxy was...

Boeing’s Orbital Flight Test-2 will be Starliner’s second uncrewed flight test and will dock to the Inter...
This new NASA Hubble Space Telescope image captures the central region of the gigantic elliptical galaxy NGC 474. Located some 100 million light-years from Earth, NGC 474 spans about 250,000 light-years across – that’s 2.5 times larger than our own Milky Way galaxy! Along with its enormous size, NGC 474 has a series of complex layered shells that surround it...

Evoking the experimental nature of flight testing and the spirit of aeronautical exploration, Quesst is what NASA is calling its mission to enable supersonic air travel over land. This new moniker – complete with an extra “s” to represent “supersonic” – draws its inspiration from NASA’s long legacy of supersonic flight research. Quesst, which rep...
This new NASA Hubble Space Telescope image spotlights the giant elliptical galaxy, UGC 10143, at the heart of galaxy cluster, Abell 2147, about 486 million light-years away in the head of the serpent, the constellation Serpens. UGC 10143 is the biggest and brightest member of Abell 2147, which itself may be part of the much larger Hercules Supercluster of ga...
On May 11, 2022, the National Oceanic and Atmospheric Administration, or NOAA, shared the first images of the Western Hemisphere from its Geostationary Operational Environmental Satellite-T (GOES-T). Later designated GOES-18, the satellite’s Advanced Baseline Imager (ABI) instrument recently captured stunning views of Earth. Launched by NASA on March 1, GOES...
