Stars glitter in the night sky above the Earth’s atmospheric glow, as the International Space Station orbited 260 miles above the Earth as it was about to cross over the Caspian Sea. Image Credit: NASA 国际空间站即将穿过里海，围绕地球260英里的上空运行，在地球大气辉光的上方，星星在夜空中闪烁。 影像来源：NASA
A galaxy about 23 million light years away is the site of impressive, ongoing fireworks. Rather than paper, powder and fire, this galactic light show involves a giant black hole, shock waves and vast reservoirs of gas. This galactic fireworks display is taking place in NGC 4258, also known as M106,
During the 18th century, French astronomer Charles Messier compiled a list of over 100 cosmic objects that might fool fellow comet hunters into thinking they had discovered new comets. In the 1980s, an Englishman named Sir Patrick Moore produced an additional list to highlight more cosmic wonders vi
NASA astronaut Christina Koch makes observations from the International space Station’s cupola. Koch has already made history once in her stay aboard the orbital laboratory. In October 2019 she was part of the first all-female spacewalk and now she is poised to make history again. On Dec. 28,
The Anti-Atlas Mountains of Morocco formed as a result of the collision of the African and Eurasian tectonic plates about 80 million years ago. This collision destroyed the Tethys Ocean. The limestone, sandstone, claystone and gypsum layers that formed the ocean bed were folded and crumpled to creat
Newborn stars, hidden behind thick dust, are revealed in this image of a section of the so-called Christmas Tree Cluster from NASA’s Spitzer Space Telescope. The newly revealed infant stars appear as pink and red specks toward the center and appear to have formed in regularly spaced intervals
This image from the NASA/ESA Hubble Space Telescope shows IC 2051, a galaxy in the southern constellation of Mensa (the Table Mountain) lying about 85 million light-years away. It is a spiral galaxy, as evidenced by its characteristic whirling, pinwheeling arms, and it has a bar of stars slicing thr
This week in 1999, space shuttle Discovery, mission STS-103, launched from NASA’s Kennedy Space Center on the third Hubble Space Telescope servicing mission. Over the course of three planned extravehicular activities, the STS-103 crew restored Hubble to working order and upgraded some of its systems
As the holiday season approaches, people in the northern hemisphere will gather indoors to stay warm. In keeping with the season, astronomers have studied two groups of galaxies that are rushing together and producing their own warmth. The majority of galaxies do not exist in isolation. Rather, they
iss061e077393 (Dec. 12, 2019) — The Canadarm2 robotic arm with the Dextre robotic hand attached seemingly protrudes from the side of the International Space Station as the orbiting complex soared 263 miles above the South Pacific Ocean. iss061e077393(2019年12月12日)——当环绕地球飞行的国际空间站在南太平洋上空263英里的高空飞
