Astronomers obtain sky's large-field X-ray maps
Sep 06, 2022 (XNA)
The Wide-field X-ray Telescope, launched into orbit on July 27 by a solid-propellant-fuelled rocket, is the first large-field X-ray imaging telescope, according...
ALMA witnesses deadly star-slinging tug-of-war between merging galaxies
Sep 06, 2022 (SPX)
As galaxies move through the Universe, they sometimes encounter other galaxies. As they interact, each galaxy's gravity pulls on the other. The ensuing tug-of-w...
Unraveling the mysteries of the night sky with Artificial Intelligence
Sep 02, 2022 (SPX)
With its luminous phenomena, the night skies often make us wonder. Some we can explain: the sparkling of the stars, caused by atmospheric turbulences, or shooti...
Webb inspects the heart of the Phantom Galaxy
Aug 30, 2022 (ESA)
The Phantom Galaxy is around 32 million light-years away from Earth in the constellation Pisces, and lies almost face-on to Earth. This, coupled with its well-d...
Discovery of the oldest visible planetary nebula hosted by a 500 million year old galactic cluster
Aug 30, 2022 (SPX)
PNe are the ejected, glowing shrouds of dying stars that shine with a rich emission line spectrum and display, as a result, their distinct colours and shapes th...
Allen Dufort: Coding a cutting-edge space telescope
Aug 28, 2022 (SPX)
As a software engineer intern for Brown University Professor of Physics Gregory Tucker, Dufort has spent Summer 2022 writing computer code for components of a t...
As early Sun moved through Milky Way Earth's first continents formed
Aug 26, 2022 (SPX)
"As geologists, we normally think about processes internal to the earth being really important for how our planet has evolved. But we can also think about the m...
Keele researchers study turbulence raging inside distant stars
Aug 25, 2022 (SPX)
They were created using the 3D simulation software "PROMPI", which scientists have been using to investigate stellar interiors with the aim of understanding the...
NASA using astronomical forensics to study exploded star
Aug 24, 2022 (SPX)
The mission's target of study is some 11,000 light-years away from Earth, off the edge of the W-shaped constellation known as Cassiopeia. There, a massive bubbl...
The global hunt for dark matter has arrived in Australia at the Stawell Underground Physics Laboratory
Aug 24, 2022 (SPX)
Recently unveiled, the Stawell Underground Physics Laboratory (SUPL) will be the new epicentre of dark matter research in Australia. Lead researcher on the proj...
Surprising details leap out in Webb Telescope Jupiter images
Aug 23, 2022 (SPX)
One wide-field image presents a unique lineup of the planet, its faint rings and two of Jupiter's smaller satellites - Amalthea and Adrastea - against a backgro...
Webb's Jupiter images showcase auroras, hazes
Aug 23, 2022 (SPX)
"We hadn't really expected it to be this good, to be honest," said planetary astronomer Imke de Pater, professor emerita of the University of California, Berkel...
Test Chamber for NASA's new cosmic mapmaker makes dramatic entrance
Aug 18, 2022 (JPL)
Set to launch no earlier than June 2024, SPHEREx (short for Spectro-Photometer for the History of the Universe, Epoch of Reionization and Ices Explorer) will ma...
Hubble sees red supergiant star Betelgeuse slowly recovering after blowing its top
Aug 15, 2022 (SPX)
Our Sun routinely blows off parts of its tenuous outer atmosphere, the corona, in an event known as a Coronal Mass Ejection (CME). But the Betelgeuse SME blaste...
Northwestern rocket to image supernova remnant
Aug 12, 2022 (SPX)
On Aug. 21, the NASA-funded team will launch its "Micro-X" rocket from White Sands Missile Range in southern New Mexico. The rocket will spend 15 minutes in spa...
Fermi confirms star wreck as source of extreme cosmic particles
Aug 11, 2022 (SPX)
Fermi has shown that the shock waves of exploded stars boost particles to speeds comparable to that of light. Called cosmic rays, these particles mostly take th...
Stars determine their own masses
Aug 09, 2022 (SPX)
In a new study, the team discovered that star formation is a self-regulatory process. In other words, stars themselves set their own masses. This helps explain ...
Wide view of early universe hints at galaxy among the earliest ever detected
Aug 08, 2022 (SPX)
The team has identified one particularly exciting object-dubbed Maisie's galaxy in honor of project head Steven Finkelstein's daughter-that they estimate is bei...
AI helps discover new space anomalies
Aug 08, 2022 (SPX)
Most astronomical discoveries have been based on observations with subsequent computations. While the total number of observations in the 20th century was still...
RIT astrophysicists collaborate on JWST survey yielding wide view of the early universe
Aug 05, 2022 (SPX)
The images were taken from the Cosmic Evolution Early Release Science Survey (CEERS), led by a scientist at The University of Texas at Austin. Jeyhan Kartaltepe...
