照料植物栖息地-02

NASA astronaut Michael Hopkins tends to radish plants growing for the Plant Habitat-02 experiment, which evaluates plant growth as well as nutrition and taste of the plants. In the final two weeks of 2020, crew members aboard the International Space Station conducted dozens of scientific investigations, including studies of how plants grow in microgravity, t...

猎户星云中心的混沌

Gaseous swirls of hydrogen, sulfur, and hydrocarbons cradle a collection of infant stars in this composite image of the Orion Nebula, as seen by the Hubble Space Telescope and the Spitzer Space telescope. Together, the two telescopes expose carbon-rich molecules in the cosmic cloud of this star-formation factory located 1,500 light-years away. Hubble’s...

复古前卫的NASA太空艺术

This fictional toroidal (doughnut-shaped) space colony, illustrated by Rick Guidice, is one of many artistic renderings that were born out of an art program at NASA’s Ames Research Center in the 1970s. Ames scientists conducted three different studies into how humans may one build massive space colonies. Artistic endeavors like these help form connecti...

回顾:乔治·卡拉瑟斯博士和阿波罗16号远紫外线照相机/摄谱仪

Dr. George Carruthers, a scientist at the Naval Research Laboratory, stands to the right of his invention, the gold-plated ultraviolet camera/spectrograph. The first Moon-based observatory, Carruthers developed it for the Apollo 16 mission. He stands beside his colleague William Conway. Working for the Naval Research Laboratory, Carruthers had three years ea...

塑造螺旋星系

Magnetic fields in NGC 1068, or M77, are shown as streamlines over a visible light and X-ray composite image of the galaxy from the Hubble Space Telescope, NuSTAR or the Nuclear Spectroscopic Array, and the Sloan Digital Sky Survey. The magnetic fields align along the entire length of the massive spiral arms — 24,000 light years across (0.8 kiloparsecs) — im...

阿波罗8号:地出

Taken aboard Apollo 8 by Bill Anders, this iconic picture shows Earth peeking out from beyond the lunar surface as the first crewed spacecraft circumnavigated the Moon, with astronauts Anders, Frank Borman, and Jim Lovell aboard.

恒星珠宝盒

Thousands of sparkling young stars are nestled within the giant nebula NGC 3603, one of the most massive young star clusters in the Milky Way Galaxy. NGC 3603, a prominent star-forming region in the Carina spiral arm of the Milky Way about 20,000 light-years away, reveals stages in the life cycle of stars. Powerful ultraviolet radiation and fast winds from t...

大近合即将来临

The Moon, left, Saturn, upper right, and Jupiter, lower right, are seen after sunset with the Washington Monument, Thurs. Dec. 17, 2020, in Washington. The two planets are drawing closer to each other in the sky as they head towards a “great conjunction” on Dec. 21, where the two giant planets will appear a tenth of a degree apart.

毅力号探测器进入火星大气层

With its heat shield facing the planet, NASA’s Perseverance rover begins its descent through the Martian atmosphere in this illustration. Hundreds of critical events must execute perfectly and exactly on time for the rover to land on Mars safely on Feb. 18, 2021. Entry, Descent, and Landing, or “EDL,” begins when the spacecraft reaches the top of the M...

繁星之夜

The Hubble Space Telescope captured a crowd of stars that looks rather like a stadium darkened before a show, lit only by the flashbulbs of the audience’s cameras. Yet the many stars of this object, known as Messier 107, are not a fleeting phenomenon, at least by human reckoning of time – these ancient stars have gleamed for many billions of year...
