保护地球，探索宇宙，发现文明
NASA astronaut Victor Glover speaks with students about his time aboard the International Space Station, Thursday, Nov. 18, 2021, at Ben’s Chili Bowl in Washington. Students from Cardozo Educational Campus, Friendship Technology Preparatory High School, McKinley Technical High School, Phelps High School, and Wilson High School heard NASA astronauts Glover, M...
Looking much like ghosts, a pair of U.S. spacesuits are pictured inside the International Space Station’s Quest airlock ready for an upcoming spacewalk to be conducted by NASA astronauts Thomas Marshburn and Kayla Barron. 看上去很像幽灵，图中一对美国宇航服在国际空间站的探索气闸内，为美国宇航局宇航员托马斯·马什本和凯拉·巴伦即将进行的太空行走做准备。 Image Credit: NASA 图片来源：美国宇航局
Stars are born from clouds of gas and dust that collapse under their own gravitational attraction. As the cloud collapses, a dense, hot core forms and begins gathering dust and gas, creating an object called a “protostar.” 恒星是由气体云和尘埃在自身引力作用下坍缩而形成。随着云团坍缩，会形成一个致密、炽热的核心，并开始聚集尘埃和气体，形成一个称为“原恒星”的物体。 This Hubble infrared image captures a protostar designated J16728...
As the International Space Station orbits the Earth, the crew makes observations of the universe and our home planet. This image taken from the space station shows the blue-green waters around the Bahamas, as shown in Space Station highlights for the week of Nov. 8, 2021. 当国际空间站绕地球运行时，宇航员对宇宙和我们的地球进行观察。这张从空间站拍摄的照片显示了巴哈马群岛周围的蓝绿色水域，如图所示，这是2021年11月8日这一周的空间站亮点。 I...

A SpaceX Falcon 9 rocket carrying the company’s Crew Dragon spacecraft is launched on NASA’s SpaceX Crew-3 mission to the International Space Station with NASA astronauts Raja Chari, Tom Marshburn, Kayla Barron, and ESA (European Space Agency) astronaut Matthias Maurer onboard, Wednesday, Nov. 10, 2021, at NASA’s Kennedy Space Center in Florida. NASA’s...
During its 36th low pass over Jupiter, NASA’s Juno spacecraft captured this view of striking cloud bands and swirls in the giant planet’s mid-southern latitudes. The dark, circular vortex near the center of the image is a cyclone that spans roughly 250 miles (about 400 kilometers). The color at its center is likely to be the result of descending winds that c...
The SpaceX Crew Dragon Endeavour spacecraft is lifted onto the GO Navigator recovery ship after it landed with NASA astronauts Shane Kimbrough and Megan McArthur, Japan Aerospace Exploration Agency (JAXA) astronaut Aki Hoshide, and ESA (European Space Agency) astronaut Thomas Pesquet in the Gulf of Mexico off the coast of Pensacola, Florida, Monday, Nov. 8, ...
This image shows knots of cold, dense interstellar gas where new stars are forming. These Free-floating Evaporating Gaseous Globules (frEGGs) were first seen in Hubble’s famous 1995 image of the Eagle Nebula. Because these lumps of gas are dark, they are rarely seen by telescopes. They can be observed when the newly forming stars ignite, their intense ultrav...
The aurora borealis glow on the northern horizon while stars wheel overhead in this long exposure, taken near the Bonneville Salt Flats in Utah on Nov. 4, 2021. Sky watchers in many locations were treated to unusually intense light displays, thanks to a geomagnetic storm created when multiple coronal mass ejections (CMEs) of charged particles from the Sun in...
