保护地球，探索宇宙，发现文明
NASA’s Jet Propulsion Laboratory (JPL) has had many famous and interesting visitors over the years, from fellow scientists, to film industry stars, to musicians, to reporters, and many more. One notable visit was from legendary actor and diplomat, Sidney Poitier. One of the first Black actors to win an Academy Award, which he did for Best Actor for Lil...
This image shows the James Webb Space Telescope (JWST) atop its launch vehicle, but before it was encapsulated in the rocket fairing. The telescope is encased in protective clean tent. 这张图片显示了詹姆斯·韦伯太空望远镜（JWST）在其运载火箭顶部，但在它被封装在火箭整流罩之前。望远镜被包裹在保护性干净的帐篷中。 On Saturday, Jan. 8, the agency will provide live coverage the James Webb Space Telescope’s major spacecraft ...
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...
NASA’s X-59 Quiet SuperSonic Technology aircraft (QueSST) is pictured here at Lockheed Martin Skunk Works in California, wrapped up in preparation for its move to Texas. The X-plane will undergo ground tests to ensure it can withstand the stresses of flight before returning to California for completion. Credits: Lockheed Martin 图为NASA的X-59安静超音速技术飞机（QUSST）在加利...

NASA’s James Webb Space Telescope, or JWST, launched aboard Arianespace’s Ariane 5 rocket on Saturday, Dec. 25, 2021, from the ELA-3 Launch Zone of Europe’s Spaceport at the Guiana Space Centre in Kourou, French Guiana. JWST is an infrared telescope with a 21.3 foot (6.5 meter) primary mirror. The observatory will study every phase of cosmic history—fr...
This composite image made from seven frames shows the International Space Station, with a crew of seven onboard, in silhouette as it transits the Sun at roughly five miles per second, Friday, June 25, 2021, from near Nellysford, Va. Onboard are Expedition 65 NASA astronauts Megan McArthur, Mark Vande Hei, Shane Kimbrough, ESA (European Space Agency) astronau...
Arianespace’s Ariane 5 rocket with NASA’s James Webb Space Telescope onboard, is rolled out to the launch pad, Thursday, Dec. 23, 2021, at Europe’s Spaceport, the Guiana Space Center in Kourou, French Guiana. The James Webb Space Telescope is a large infrared telescope with a 21.3 foot (6.5 meter) primary mirror. The observatory will study every phase ...
The Compact Ocean Wind Vector Radiometer (COWVR) is no bigger than a minifridge. The Temporal Experiment for Storms and Tropical Systems (TEMPEST) is even smaller – about the size of a cereal box. Yet these two compact science instruments are designed to do a big job: to make the same high-quality atmospheric observations as weather satellites many times the...
The Earth’s solstices come twice a year. For the Northern Hemisphere, the summer (June) solstice occurs around June 20-21, and the winter (December) solstice happens around Dec. 21-22. 地球的至日一年有两次。对于北半球来说，夏至发生在6月20-21日左右，冬至发生在12月21-22日左右。 At the solstice, the Sun’s path appears farthest north or south, depending on which half of the planet you are on. S...
