In a galaxy 100 light-years away in the constellation Dorado sits a planetary system named TOI 700. It is home to TOI 700 d, the first Earth-size habitable-zone planet discovered by TESS, NASA’s Transiting Exoplanet Survey Satellite. Image Credit: NASA/Goddard Space Flight Center 在离我们100光年的多拉多 […]
On Jan.1, 2020, NASA Administrator Jim Bridenstine tweeted: “Making progress! The massive @NASA_SLS core stage is moving to Building 110 at the Michoud Assembly Facility in Louisiana. There it will be readied for the Pegasus barge and its trip to @NASAStennis. Thank you to the @NASA team for
This smattering of celestial sequins is a spiral galaxy named NGC 4455, located in the northern constellation of Coma Berenices (Berenice’s Hair). This might sound like an odd name for a constellation — and in fact it is somewhat unusual. It’s the only modern constellation to be named in honor of a
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
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
