Webb peers behind bars
Jun 02, 2023 (ESA)
This portrait of NGC 5068 is part of a campaign to create an astronomical treasure trove, a repository of observations of star formation in nearby galaxies. Pre...
Weigh a quasar's galaxy with precision
Jun 02, 2023 (SPX)
"The unprecedented precision and accuracy achieved with gravitational lensing provide a new avenue for obtaining robust mass estimates in the distant Universe, ...
Mysterious dashes revealed in Milky Way's center
Jun 02, 2023 (SPX)
In the early 1980s, Northwestern University's Farhad Yusef-Zadeh discovered gigantic, one-dimensional filaments dangling vertically near Sagittarius A*, our gal...
NASA looks back at 50 years of gamma-ray burst science
Jun 02, 2023 (SPX)
"I can still remember the excitement when gamma-ray bursts were discovered," said Charles Meegan, a research scientist at the University of Alabama, Huntsville,...
Helium nuclei research advances our understanding of cosmic ray origin and propagation
May 26, 2023 (SPX)
Detailed observations of cosmic rays can, thus, not only shed light on the origins of these particles but also decode the existence of high-energy objects and p...
Study doubles the number of known repeating fast radio bursts
May 26, 2023 (SPX)
Now, a large team of astronomers, including several from the MIT Kavli Institute for Astrophysics and Space Research and the MIT Department of Physics, have col...
Astronomers detected two major targets with a single telescope - a mysterious signal and its source galaxy
May 26, 2023 (SPX)
Now, a study of the slow-moving, star-forming gas in the same galaxy found to host an FRB has been published in The Astrophysical Journal. This is only the four...
Multifunctional interface enables manipulation of light waves in free space
May 25, 2023 (SPX)
Combining these structures allows for the creation of compact optical systems. The PICs can be used to make subtle changes to the light wave, such as the manipu...
Element creation in the lab deepens understanding of surface explosions on neutron stars
May 25, 2023 (SPX)
"Neutron stars are really fascinating from the points of view of both nuclear physics and astrophysics," said ORNL nuclear astrophysicist Kelly Chipps, who led ...
Light shining through a wall experiment searches for dark matter
May 24, 2023 (SPX)
Axions are believed to interact very weakly with known forms of matter, rendering them virtually undetectable through conventional accelerator experiments. Inst...
An X-ray look at the heart of powerful quasars
May 19, 2023 (SPX)
Hosted by a galaxy 9.6 billion light years away from the Earth, between the constellations of Centaurus and Hydra, J1144 is extremely powerful, shining 100,000 ...
Chinese astronomers transform understanding of Milky Way's spiral structure
May 19, 2023 (SPX)
Largely speaking, there are three types of spiral galaxies in the universe. Grand-design spiral galaxies are characterized by clear, long and symmetrical spiral...
Radio signal reveals supernova origin
May 18, 2023 (SPX)
Supernovae of Type Ia are important for astronomers since they are used to measure the expansion of the Universe. However, the origin of these explosions has re...
