NASA ABoVE团队研究融化的永久冻土,湖泊

Since 2015, scientists participating in NASA’s Arctic Boreal Vulnerability Experiment (ABoVE) have been studying the impacts of climate change on Earth’s far northern regions and how those changes are intertwined. As our planet warms, permafrost—layers of soil that have stayed frozen for at least tw […]

压力测试超级大黄蜂的翅膀

Teams at NASA’s Armstrong Flight Research Center in Edwards, California, recently completed stress testing on the Navy’s F/A-18E Super Hornet aircraft from the Naval Air Systems Command (NAVAIR) in Patuxent River, Maryland. The Super Hornet is seen here in a top view from March 2022 while in a

露齿葫芦装点银河

While observing the outer region of the Milky Way galaxy, our Spitzer Telescope captured this infrared image of a cloud of gas and dust that looks like the hollowed-out pumpkins we see every Halloween. Nicknamed the “Jack-o’-Lantern Nebula,” it was likely created by powerful outflows of radiation an

韦伯揭示了创生之柱的新细节

Our James Webb Space Telescope has captured a new image of the famous Pillars of Creation—first imaged by the Hubble Space Telescope in 1995—that reveals new details about the region. The three-dimensional pillars look like majestic rock formations but are far more permeable. These columns are made

露西发现了地球和月球

On Oct. 13, 2022, NASA’s Lucy spacecraft captured this image of the Earth and the Moon from 890,000 miles (1.4 million km) away. The image was taken as part of an instrument calibration sequence as the spacecraft approached Earth for its first of three Earth gravity assists. These Earth flybys provi

绘制整个夜空

This mosaic is composed of images covering the entire sky, taken by the Wide-field Infrared Survey Explorer (WISE) as part of WISE’s 2012 All-Sky Data Release. By observing the entire sky, WISE could search for faint objects, like distant galaxies, or survey groups of cosmic objects. Not visible to

木卫三阴影中的木星

During its 40th close pass by Jupiter, our Juno spacecraft saw Ganymede cast a large, dark spot on the planet on Feb. 25, 2022. JunoCam captured this image from very close to Jupiter, making Ganymede’s shadow appear especially large. At the time the raw image was taken, the Juno spacecraft was about

IXPE测量爆炸的恒星残骸

When a massive star collapsed in the Cassiopeia constellation, it generated a supernova explosion with some of the fastest shockwaves in the Milky Way. These speedy shock waves are one of the reasons the Cassiopeia A (Cas A) supernova remnant was chosen to be our Imaging X-ray Polarimetry Explorer’s
