The Small Magellanic Cloud (SMC), located 210,000 light-years away, is one of the most dynamic and intricately detailed star-forming regions in space. At the center of the region is a brilliant star cluster called NGC 346. A dramatic structure of arched, ragged filaments with a distinct ridge surrounds the cluster. A torrent of radiation from the cluster’s hot stars eats into denser areas creating a fantasy sculpture of dust and gas. The dark, intricately beaded edge of the ridge, seen in silhouette by Hubble, is particularly dramatic. It contains several small dust globules that point back towards the central cluster, like windsocks caught in a gale. Energetic outflows and radiation from hot young stars are eroding the dense outer portions of the star-forming region, formally…

Contamination control engineers in a clean room at the Goddard Space Flight Center evaluate a propellant tank before it is installed in our Europa Clipper spacecraft. The tank is one of two that will be used to hold the spacecraft’s propellant. It will be inserted into the cylinder seen at left in the background, one of two cylinders that make up the propulsion module. With an internal global ocean under a thick layer of ice, Jupiter’s moon Europa may have the potential to harbor existing life. Europa Clipper will swoop around Jupiter on an elliptical path, dipping close to the moon on each flyby to collect data. Understanding Europa’s habitability will help scientists better understand how life developed on Earth and the potential for finding…

On Women’s Equality Day, NASA celebrates the women who are breaking barriers and paving the way for future generations. In this image, Dr. Nancy Grace Roman (1925-2018), NASA’s first Chief of Astronomy and “the Mother of Hubble,” visits the Space Telescope Operations Control Center at the Goddard Space Flight Center on March 31, 2017, and meets with some women from the Hubble Space Telescope project. Left to right: Beverly Serrano, Morgan Van Arsdall, Nancy Grace Roman, Olivia Lupie, Padi Boyd, and Erin Kisliuk. The Wide Field Infrared Survey Telescope, a mission concept to answer vital questions in both exoplanet detection and dark energy research, was renamed the Nancy Grace Roman Space Telescope in her honor. Women’s Equality Day is celebrated on Aug. 26 each year…

The SpaceX Crew-3 team, consisting of NASA astronauts Raja Chari, Kayla Barron, and Tom Marshburn, and ESA astronaut Matthias Maurer, and support personnel participate in water survival training at the Neutral Buoyancy Laboratory at NASA’s Johnson Space Center in this image from April 2021. The mission is slated to launch in late 2021. When Barron, Chari, Marshburn, and Maurer arrive at the orbiting laboratory, they will become expedition crew members for the duration of their six-month science mission. The crew will have a slight overlap with the Crew-2 astronauts, who arrived April 24. This will mark the second time commercial crew missions have overlapped on the station. The Crew-1 astronauts, who ended their mission with a splashdown off the coast of Panama City, Florida, on…

Who is Bill Ingalls? He’s a senior contract photographer at NASA Headquarters in Washington, with more than three decades of documenting America’s space and aeronautics programs. For his efforts, he received the 2021 Douglas S. Morrow Public Outreach Award on Aug. 23, 2021 at the 36th annual Space Symposium in Colorado Springs, Colo. Ingalls has photographed many of NASA’s most seminal moments since 1989, from the extraordinary to mundane, from the 2017 total solar eclipse to the final shuttle mission to snapping pics of senior agency officials. Ingalls also led a team of photographers at NASA Headquarters for more than two decades to document the agency’s missions, as well as performing his own. Check out their work on Flickr. His work was also the subject…

Gene Roddenberry would have been 100 years old on Aug. 19, 2021, and we at NASA celebrate his legacy. As creator of the legendary Star Trek saga, Roddenberry’s vision continues to resonate. In the documentary “NASA on the Edge of Forever: Science in Space,” host NASA astronaut Victor Glover stated, “Science and Star Trek go hand-in-hand.” The film explores how for the past 55 years, Star Trek has influenced scientists, engineers, and even astronauts to reach beyond. While the International Space Station doesn’t speed through the galaxy like the Starship Enterprise, much of the research conducted aboard the orbiting facility is making the fiction of Star Trek come a little closer to reality. In this image, the then Dryden Flight Research Center (now Armstrong) hosted…

缺乏暗物质的幽灵星系

缺乏暗物质的幽灵星系

ByNASA中文

Galaxies and dark matter go together like peanut butter and jelly. Rarely is one without the other, but a recently discovered galaxy called NGC 1052-DF2 is nearly entirely lacking in dark matter. In November 2019, researchers were astonished when they viewed its image captured by the Hubble Space Telescope. Dark matter is an invisible substance that astronomers believe plays an important role in the formation of galaxies and is thought to comprise 85 percent of the universe’s mass. This discovery not only challenges the ideas of how galaxies form, but also provides evidence that dark matter is real. It shows that dark matter is not always coupled with regular matter in galaxies and that it has its own separate existence. In addition to lacking dark…

In this image, a NASA Black Brant XII suborbital sounding rocket was launched at 8:44 p.m. EDT, Sunday, May 16, 2021, from the Wallops Flight Facility. The four stage rocket carried the KiNETic-scale energy and momentum transport eXperiment, or KiNet-X, designed to study a very fundamental problem in space plasmas, namely, how are energy and momentum transported between different regions of space that are magnetically connected. These student-designed projects are a mix of technology and science experiments, including the development of a 360-degree camera for use on sounding rockets; space debris removal concepts; a solar array deployment system for CubeSats; and collection of particles in space for research on the origins of life.
