5 min read NASA’s Fermi Detects Surprise Gamma-Ray Feature Beyond Our Galaxy This artist’s concept shows the entire sky in gamma rays with magenta circles illustrating the uncertainty in the direction from which more high-energy gamma rays than average seem to be arriving. In this view, the plane of our galaxy runs across the middle of the map. The circles enclose regions with a 68% (inner) and a 95% chance of containing the origin of these gamma rays. NASA’s Goddard Space Flight Center Astronomers analyzing 13 years of data from NASA’s Fermi Gamma-ray Space Telescope have found an unexpected and as yet unexplained feature outside of our galaxy. “It is a comp…

5 min read NASA Scientists Discover a Novel Galactic ‘Fossil’ Researchers at NASA’s Goddard Space Flight Center in Greenbelt, Maryland, have discovered X-ray activity that sheds light on the evolution of galaxies. The X-rays outline giant clouds of cold gas in the nearby spiral galaxy NGC 4945. The gas appears to have blasted through the galaxy after its central supermassive black hole erupted some 5 million years ago. Some 5 million years ago, a black hole eruption in the galaxy NGC 4945 set off a star-formation frenzy and shot a vast cloud of gas into intergalactic space. Watch and learn how two X-ray telescopes revealed the story. Credit: NASA’s Goddard Space …

These images represent a sample of galaxy clusters that are part of the largest and most complete study to learn what triggers stars to form in the universe’s biggest galaxies. Clusters of galaxies are the largest objects in the universe held together by gravity and contain huge amounts of hot gas seen in X-rays. This research, made using Chandra and other telescopes, showed that the conditions for stellar conception in these exceptionally massive galaxies have not changed over the last ten billion years. In these images, X-rays from Chandra are shown along with optical data from Hubble.X-ray: NASA/CXC/MIT/M. Calzadilla el al.; Optical: NASA/ESA/STScI; Image Processing: N…

Satellite imagery shows a portion of East Antarctica on Jan. 9, 2022, before icebergs calved off the Glenzer and Conger glaciers. NISAR will observe nearly all of the planet’s land and ice surfaces twice every 12 days, monitoring Earth’s frozen regions, known as the cryosphere.USGS Much of the Glenzer and Conger glaciers had collapsed by March 23, 2022, spawning numerous icebergs, as shown in this satellite image. NISAR will document such changes around the globe, and its geographic coverage of Antarctica will be the most extensive for a radar satellite mission to date.USGS …

1 min read Preparations for Next Moonwalk Simulations Underway (and Underwater) Nenad Miljkovic University of Illinois at Urbana-Champaign Traditional elastocaloric refrigeration systems are based on uniaxial compression of the elastocaloric material which makes them highly constrained by actuator requirements, the physics of column buckling, and limited surface area for heat transfer. Professor Miljkovic will investigate a novel elastocaloric system based on bending of the elastocaloric material, which removes these constraints. The design requires less energy for equivalent performance and can be run in a continuous loop further increasing efficiency. The team wi…

To replace the cargo and crew transportation services to and from the International Space Station following the retirement of the space shuttle in 2011, the United States developed a novel approach to procure those services from American commercial entities. On Jan. 9, 2014, Orbital Sciences Corporation, one of two companies selected initially to provide cargo transportation services, launched the first operational mission of its Cygnus spacecraft. During its one-month stay at the space station, the onboard Expedition 38 crew unloaded its cargo and then filled it with trash and unneeded equipment before releasing it for a destructive reentry. The novel approach of the gov…
