The study, which has been published in The Astrophysical Journal Letters, examined a group of stars located in the nuclear star cluster that makes up the heart ...
NASA Engineers Push Limits of Physics to Focus Light
Dec 06, 2023 (SPX)
Heliophysicist Dr. Doug Rabin at NASA's Goddard Space Flight Center in Greenbelt, Maryland, said photon sieves, a technology that can focus extreme ultraviolet ...
Unlocking neutron star rotation anomalies: Insights from quantum simulation
Dec 06, 2023 (SPX)
This phenomenon suggests that neutron stars might be partly superfluid. In a superfluid, rotation is characterized by numerous tiny vortices, each carrying a fr...
10 billion year, 50,000 light-year journey to black hole
Dec 05, 2023 (SPX)
Many stars are observed near the supermassive black hole known as Sagittarius A* at the center of our Galaxy. But the black hole's intense gravity makes the sur...
Dark galactic region nicknamed The Brick explained with Webb telescope findings
Dec 05, 2023 (SPX)
To decipher its secrets, Ginsburg and his research team, including UF graduate students Desmond Jeff, Savannah Gramze, and Alyssa Bulatek, turned to the James W...
STS-61, the First Hubble Servicing Mission
Dec 05, 2023 (SPX)
The first Hubble servicing mission proved to be one of the most complex up to that time. With that in mind, on March 16, 1992, NASA named Musgrave, an astronaut...
Interstellar Mapping and Acceleration probe passes key milestone
Dec 04, 2023 (SPX)
Originally planned for no earlier than February 2025, the IMAP's launch date underwent a strategic reassessment during the KDP-D. This revision was undertaken t...
Sea fireflies synchronize their sparkle to seek soulmates
Dec 04, 2023 (SPX)
Hensley is the lead author of new research unwrapping the vivid mating ritual of minute crustaceans called ostracods, which was published Nov. 29 in the Proceed...
Ghostlike dusty galaxy reappears in James Webb Space Telescope image
Dec 04, 2023 (SPX)
Astronomers with the COSMOS-Web collaboration have identified the object AzTECC71 as a dusty star-forming galaxy. Or, in other words, a galaxy that's busy formi...
Hypernebula linked to Fast Radio Burst 20190520B
Dec 04, 2023 (SPX)
Fast Radio Bursts are fleeting but powerful bursts of radio waves, originating billions of lightyears away. Some, like FRB 20121102A, are known to repeat, offer...
New astrophysics model sheds light on additional source of long gamma-ray bursts
Nov 30, 2023 (SPX)
Astronomers previously thought that black holes that generate long GRBs typically form when massive stars collapse. However, the new model shows that they can a...
Hubble pauses science due to gyro issue
Nov 30, 2023 (SPX)
The telescope automatically entered safe mode when one of its three gyroscopes gave faulty readings. The gyros measure the telescope's turn rates and are part o...
NASA's Fermi Mission Nets 300 Gamma-Ray Pulsars ... and Counting
Nov 29, 2023 (SPX)
"Pulsars touch on a wide range of astrophysics research, from cosmic rays and stellar evolution to the search for gravitational waves and dark matter," said stu...
Earth's magnetic field protects life on Earth from radiation
Nov 28, 2023 (SPX)
I'm a physicist who studies the interaction between the planets and space. While the north magnetic pole moving a little bit isn't a big deal, a reversal could ...
Understanding charged particles helps physicists simulate element creation in stars
Nov 28, 2023 (SPX)
Predicting the ways that atomic nuclei - clusters of protons and neutrons, together referred to as nucleons - combine to form larger compound nuclei is an impor...
Wits researchers pioneer a new way of searching for dark matter
Nov 28, 2023 (SPX)
However, up to date, no experimental observation of dark matter has been reported. The existence of Dark Matter has been a question that high energy and astroph...
Telescope Array detects second highest-energy cosmic ray ever
Nov 24, 2023 (SPX)
The Telescope Array has since observed more than 30 ultra-high-energy cosmic rays, though none approaching the Oh-My-God-level energy. No observations have yet ...
Dwarf galaxies use 10-million-year quiet period to churn out stars
Nov 23, 2023 (SPX)
Now, University of Michigan researchers have discovered the reason underlying this: These galaxies enjoy a 10-million-year delay in blowing out the gas clutteri...
Boomerang-like beams of light
Nov 21, 2023 (SPX)
"Imagine that you are throwing a tennis ball. The ball starts moving forward with positive momentum. If the ball doesn't hit an obstacle, you are unlikely to ex...
University of Helsinki researchers solve cosmic conundrum
Nov 21, 2023 (SPX)
Most galaxies in the universe fall into one of two categories: firstly, elliptical galaxies, made mostly of old stars and containing typically extremely massive...
