Hurricanes are the most powerful weather event on Earth. The 2022 Atlantic hurricane season extends from June 1 to November 30. Faster than a cheetah, the fastest animal on land, hurricanes produce winds of 74 miles an hour (119 kilometers per hour) or more. In this image from 2021, the crew aboard the International Space Station snapped this image of Hurric...
The Moon, with Earth’s shadow draping across it during the May 15, 2022, lunar eclipse, is pictured in between the International Space Station’s Nauka multipurpose laboratory module and the Rassvet module. Attached to Nauka is the new European robotic arm that was continuing checkouts and mobility tests. Image Credit: NASA 在2022年5月15日的月食期间，月球被地球的...
This new image from NASA’s Hubble Space Telescope looks at two spiral galaxies, collectively known as Arp 303. The pair, individually called IC 563 (bottom right) and IC 564 (top left), are 275 million light-years away in the direction of the constellation Sextans. The image holds data from two separate Hubble observations of Arp 303. The first used Hubble’s...
Boeing’s CST-100 Starliner spacecraft opens its main parachutes as it lands at White Sands Missile Range’s Space Harbor, Wednesday, May 25, 2022, in New Mexico. Boeing’s Orbital Flight Test-2 (OFT-2) is Starliner’s second uncrewed flight test to the International Space Station as part of NASA’s Commercial Crew Program. OFT-2 serves as an end-to-end tes...
Since the days of NASA’s Apollo program, astronauts have documented (and contended with) how liquids behave differently in microgravity than they do on Earth – coalescing into floating spheres instead of bottom-heavy droplets. Now, researchers have demonstrated this effect with a much more exotic material: gas cooled to nearly absolute zero (minus 459 degree...
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...
A United Launch Alliance Atlas V rocket with Boeing’s CST-100 Starliner spacecraft aboard launched from Space Launch Complex 41, Thursday, May 19, 2022, at Cape Canaveral Space Force Station in Florida. Boeing’s Orbital Flight Test-2 (OFT-2) is Starliner’s second uncrewed flight test and will dock to the International Space Station as part of NASA’s Co...
A United Launch Alliance Atlas V rocket with Boeing’s CST-100 Starliner spacecraft aboard is illuminated by spotlights on the launch pad at Space Launch Complex 41 ahead of the Orbital Flight Test-2 mission in this image taken on Wednesday, May 18, 2022. 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...
