土星环的景观

This artist’s illustration shows the Cassini spacecraft in orbit around Saturn. Cassini made 22 orbits that swooped between the rings and the planet before ending its 13-year tour of the ringed planet on Sept. 15, 2017, with a final plunge into Saturn. Cassini spacecraft shared the wonders of Saturn and its family of icy moons—taking us to astounding w...

庆祝在木星的5周年

On July 4, 2016, our Juno spacecraft arrived at Jupiter on a mission to peer through the gas giant planet’s dense clouds and answer questions about the origins of our solar system. Since its arrival, Juno has provided scientists with a treasure trove of data about the planet’s origins, interior structures, atmosphere and magnetosphere. Juno is the first miss...

向航天飞机收尾工作人员致敬

This uniform in the center of this image belonged to one of the unsung heroes of the Space Shuttle Program – Travis Thompson, former Closeout Crew Lead. The closeout crew was responsible for assisting the astronauts to strap into the shuttle’s crew module and take care of any other last-minute needs that arose. Ultimately, they close and seal the crew ...

SpaceX龙补给飞船离开空间站

The SpaceX Cargo Dragon resupply ship departs the International Space Station after it undocked from the Harmony module’s space-facing international docking adapter on July 8, 2021.

哈勃望远镜瞥见一对星系二人组

Two enormous galaxies capture your attention in this spectacular image taken with the NASA/ESA Hubble Space Telescope using the Wide Field Camera 3 (WFC3). The galaxy on the left is a lenticular galaxy, named 2MASX J03193743+4137580. The side-on spiral galaxy on the right is more simply named UGC 2665. Both galaxies lie approximately 350 million light-years ...

小行星带中有一颗斯塔尔星

Our birthday wishes for Ringo Starr’s 81st birthday are almost boundless, extending all the way beyond Mars to our solar system’s asteroid belt, home to the asteroid that bears his name, 4150 Starr. Learn more about the planetary body that bears his name. Image Credit: NASA 我们对林戈·斯塔尔(Ringo Starr)81岁生日的祝福几乎是无限的,一直延伸到火星以外的太阳系小行星带,那里有以他的名字命名的小行星,415...

在围绕红矮星的轨道上运行

Planet TOI-1231 b orbits a red dwarf star some 90 light-years away from Earth and is oddly reminiscent of our own Neptune ­– that is, a gaseous world with a potentially rich atmosphere, ripe for study. The planet is more than 3 ½ times as big around as Earth and warm by Earthly standards at 134 degrees Fahrenheit (57 Celsius). But astronomers say it is one o...

哈勃望远镜观测到了一个由红、白、蓝组成的星团

This image taken with the NASA/ESA Hubble Space Telescope depicts the open star cluster NGC 330, which lies around 180,000 light-years away inside the Small Magellanic Cloud. The cluster – which is in the constellation Tucana (the Toucan) – contains a multitude of stars, many of which are scattered across this striking image. Because star clusters form from ...

钱德拉提高了银河系中心的温度

This 2004 image was produced by combining a dozen observations from the Chandra X-Ray Observatory made of a 130 light-year region in the center of the Milky Way. The colors represent low (red), medium (green) and high (blue) energy X-rays. Thanks to Chandra’s unique resolving power, astronomers have now been able to identify thousands of point-like X-r...

描绘太阳系的小行星带

Today(Editor’s Note: June 30) is International Asteroid Day! Asteroids, sometimes called minor planets, are rocky remnants left over from the early formation of our solar system about 4.6 billion years ago. The current known asteroid count is more than one million! Most of this ancient space rubble can be found orbiting our Sun between Mars and Jupiter...
