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 […]
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
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 observ

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 a
