This celestial cloudscape from the NASA/ESA Hubble Space Telescope captures the colorful region in the Orion Nebula surrounding the Herbig-Haro object HH 505. Herbig-Haro objects are luminous regions surrounding newborn stars that form when stellar winds or jets of gas spew from these infant stars creating shockwaves that collide with nearby gas and dust at ...
In this picture from 2016, our Super Guppy, a specialized aircraft with a unique hinged nose, lands at Moffett Field at NASA Ames. Boasting an immense cargo area that is 25 feet in diameter and 111 feet long, the Super Guppy can carry items that are virtually impossible to fit inside other cargo aircraft. In early August 2022, it arrived at Marshall with a s...
This Moon-mosaic is comprised of 1,231 images taken by the Lunar Reconnaissance Orbiter’s (LRO) Narrow-Angle Camera (NAC) in the summer of 2018. The LRO team chose each tile from over 10,000 of the highest quality LROC NAC frames by searching for the best match of brightness and gradient (the direction and size of the brightness change across the frame...
Today marks 10 years since the Curiosity rover landed on Mars. Since August 2012, Curiosity has been exploring 3-mile-high Mt. Sharp in Gale Crater. The rover has climbed more than 2,000 feet (612 meters), reaching progressively younger rocks that serve as a record on how Mars has evolved from a wet, habitable planet to a cold desert environment. The photoge...
Like distant galaxies amid clouds of interstellar dust, chunks of sea ice drift through graceful swirls of grease ice in the frigid waters of Foxe Basin near Baffin Island in the Canadian Arctic. Sea ice often begins as grease ice, a soupy slick of tiny ice crystals on the ocean’s surface. As the temperature drops, grease ice thickens and coalesces int...
With wildflowers surrounding the view, NASA’s Space Launch System (SLS) Moon rocket – carried atop the Crawler-Transporter 2 – arrives at Launch Pad 39B at the agency’s Kennedy Space Center in Florida on June 6, 2022. The first in an increasingly complex series of missions, Artemis I will test the SLS rocket and Orion spacecraft as an integrated system prior...
一个巨大的粉红色斑点星系，像一个轮子，内部有一个小的椭圆形的内环，中间是尘土飞扬的蓝色。左边有两个较小的螺旋星系，在黑色背景下大小大致相同。 影像来源：NASA, ESA, CSA, STScI NASA的詹姆斯·韦伯太空望远镜观察了混乱的车轮星系，揭示了有关恒星形成和星系中心黑洞的新细节。韦伯强大的红外观测产生了这张车轮星系和两个较小伴星系的详细图像，背景是许多其他星系。这张图片提供了一个新的视角，展示了车轮星系在数十亿年中是如何变化的。 车轮星系位于约5亿光年外的玉夫座中，是一个罕见的景象。它的外观，很像马车的车轮，这是一个激烈事件的结果——一个大的螺旋星系和一个在这张照片中看不到的小星系之间的高速碰撞。星系比例的碰撞会导致所涉及的星系之间发生一系列不同的、较小的事件；车轮星系也不例外。 这次碰撞最显著地影...
NASA celebrates the life of Nichelle Nichols, Star Trek actor, trailblazer, and role model, who symbolized to so many what was possible. She partnered with us to recruit some of the first women and minority astronauts, and inspired generations to reach for the stars. In this photo from February 2012, Nichols was a featured guest speaker in the Building 8 aud...
Zeta Ophiuchi is a star with a complicated past, having likely been ejected from its birthplace by a powerful stellar explosion. A new look by NASA’s Chandra X-ray Observatory helps tell more of the story of this runaway star. Located about 440 light-years from Earth, Zeta Ophiuchi is a hot star that is 20 times more massive than the Sun. Previous obse...
As NASA’s Juno mission completed its 43rd close flyby of Jupiter on July 5, 2022, its JunoCam instrument captured this striking view of vortices — hurricane-like spiral wind patterns — near the planet’s north pole. These powerful storms can be over 30 miles (50 kilometers) in height and hundreds of miles across. Figuring out how they form is key to understan...
