Astronomers have detected X-rays from Uranus for the first time, using NASA’s Chandra X-ray Observatory, as shown in this image from March 2021. This result may help scientists learn more about this enigmatic ice giant planet in our solar system. Uranus is the seventh planet from the Sun and has two […]
Astronomers continue to develop computer simulations to help future observatories better home in on black holes, the most elusive inhabitants of the universe. Though black holes likely exist abundantly in the universe, they are notoriously hard to see. Scientists did not capture the first radio imag
This image shows the spiral galaxy NGC 5037, in the constellation of Virgo. First documented by William Herschel in 1785, the galaxy lies about 150 million light-years away from Earth. Despite this distance, we can see the delicate structures of gas and dust within the galaxy in extraordinary detail
过热的气体和磁场在银河系的中心编织着能量的织锦。这幅新的宇宙杰作的新图像是由美国宇航局钱德拉x射线天文台和南非的MeerKAT射电望远镜的巨大数据拼接而成的。 银河系中心的新全景图是建立在之前钱德拉和其他望远镜的观测基础上的。与以前的成像活动相比，这个最新版本将钱德拉的高能视野扩展到了银河系平面的上方和下方，也就是银河系大多数恒星所在的圆盘。在我们的主图中，来自钱德拉的X射线显示为橙色、绿色、蓝色和紫色，显示不同的X射线能量，而来自MeerKAT的无线电数据则显示为淡紫色和灰色。图片中的主要特征以标注的方式显示。 有一条线特别引人注意，因为它的X射线和无线电发射交织在一起。它垂直于银河系的平面
In just over a week on June 3, 2021, these tiny squids will head to space along with many other scientific experiments aboard SpaceX’s 22nd cargo resupply mission to the International Space Station. The squids are a part of the UMAMI study which examines the effects of spaceflight on interactions be
Perseverance Mars rover Strategic Mission Manager Pauline Hwang, gave remarks during the Perseverance rover initial surface checkout briefing on Feb. 19, 2021, at NASA’s Jet Propulsion Laboratory. The Perseverance Mars rover landed on the Red Planet on Feb. 18, 2021. A key objective for Persev
The SpaceX Crew Dragon Resilience is pictured shortly before undocking from the International Space Station’s Harmony module’s space-facing international docking adapter. Resilience splashed down in the Gulf of Mexico off the coast of Panama City, Florida, at 2:56 a.m. EDT May 2, 2021, r
NASA conducted its fourth RS-25 single-engine hot fire test of the year on May 20, 2021, a continuation of its seven-part test series to support development and production of engines for the agency’s Space Launch System (SLS) rocket on future missions to the Moon. The engine was fired for more than
NASA astronaut Mark Vande Hei peers into near-infrared medical-imaging gear, or optical coherence tomography, for detailed views of his retina as part of regularly scheduled eye checks aboard the International Space Station. Astronauts periodically check their eyes because of a phenomenon known as S
Using scientific instruments aboard a self-propelled ocean glider and several airplanes, this first deployment of the Sub-Mesoscale Ocean Dynamics Experiment (S-MODE) mission will deploy its suite of water- and air-borne instruments to ensure that they work together to show what’s happening just bel
