A violent and chaotic-looking mass of gas and dust is seen in this Hubble Space Telescope image of a nearby supernova remnant. Denoted N 63A, the object is the remains of a massive star that exploded, spewing its gaseous layers out into an already turbulent region. 在这张哈勃太空望远镜拍摄的附近超新星残余物的图像中，可以看到一团剧烈而混乱的气体和灰尘。这个天体被称为N 63A，是一颗大质量恒星的残骸，它爆炸后将其气态层喷出到一个已经很混乱的区域。 T...
This NASA/ESA Hubble Space Telescope image features two interacting galaxies that are so intertwined, they have a collective name – Arp 91. Their delicate galactic dance takes place more than 100 million light-years from Earth. The two galaxies comprising Arp 91 have their own names: the lower galaxy, which looks like a bright spot, is NGC 5953, and the oval...

This artist’s conception illustrates a Jupiter-like planet alone in the dark of space, floating freely without a parent star. 这幅艺术家的构思图说明了一颗类似木星的行星在黑暗的太空中独自游荡，没有母星。 Exoplanet hunters have found thousands of planets, most orbiting close to their host stars, but relatively few alien worlds have been detected that float freely through the galaxy as so-cal...

The Cargo Dragon’s beacon lights and a plume from one of its engines during its departure burn made for a colorful show. 这张摄于2021年9月30日的照片中，货运补给龙飞船从国际空间站的前向国际对接适...
When it comes time for NASA’s Psyche spacecraft to power itself through deep space, it’ll be more brain than brawn that does the work. Once the stuff of science fiction, the efficient and quiet power of electric propulsion will provide the force that propels the Psyche spacecraft all the way to the main asteroid belt between Mars and Jupiter. The orbiter’s t...
