Remarkably, the 2020 supernova isn’t the only one that astronomers have seen in this galaxy – UGC 9684 has hosted four supernova-like events since 2006, putting it up there with the most active supernova-producing galaxies. It turns out that UGC 9684 is a quite active star-forming galaxy, calculated as producing one solar mass worth of … Read more
While 55 Cancri e is far too hot to be habitable, researchers think it could provide a unique window for studying interactions between atmospheres, surfaces, and interiors of rocky planets, and perhaps provide insights into the early conditions of Earth, Venus, and Mars, which are thought to have been covered in magma oceans far in … Read more
The Resolve instrument aboard XRISM (X-ray Imaging and Spectroscopy Mission) captured data from the center of galaxy NGC 4151, where a supermassive black hole is slowly consuming material from the surrounding accretion disk. The resulting spectrum reveals the presence of iron in the peak around 6.5 keV and the dips around 7 keV, light thousands … Read more
When imaging faint objects such as distant stars or exoplanets, capturing every last bit of light is crucial to get the most out of a scientific mission. These cameras must be extremely low-noise, and be able to detect the smallest quantities of light—single photons. Superconducting cameras excel in both of these criteria, but have historically … Read more
“People often ask about this, and simulating these difficult-to-imagine processes helps me connect the mathematics of relativity to actual consequences in the real universe,” said Jeremy Schnittman, an astrophysicist at NASA’s Goddard Space Flight Center in Greenbelt, Maryland, who created the visualizations. “So I simulated two different scenarios, one where a camera — a stand-in … Read more
Located in the Virgo constellation, NGC 4951 is located roughly 50 million light-years away from Earth. It’s classified as a Seyfert galaxy, which means that it’s an extremely energetic type of galaxy with an active galactic nucleus (AGN). However, Seyfert galaxies are unique from other sorts of AGNs because the galaxy itself can still be … Read more
The image is from an observation program dedicated to the study of dwarf galaxies in the Virgo cluster that is searching for the visible light emissions from sources of X-rays in these galaxies. X-rays are often emitted by accretion discs, where material that is drawn into a compact object by gravity crashes together and forms … Read more
XRISM is a collaborative mission between JAXA and NASA, with contributions from over 70 institutions in Japan, the U.S., Canada, and Europe. NASA Goddard developed the Resolve detector and many of the instrument subsystems, together with the two X-ray Mirror Assemblies. Goddard is also responsible for the Science Data Center, which developed analysis software and … Read more
The magnificent central bar of NGC 2217 (also known as AM 0619-271) shines bright in the constellation of Canis Major (The Greater Dog), in this image taken by the NASA/ESA Hubble Space Telescope. Roughly 65 million light-years from Earth, this barred spiral galaxy is a similar size to our Milky Way at 100,000 light-years across. Many stars are concentrated in … Read more
