Radio view of rare supernova tracks dying star's final decade
Jan 30, 2026 (SPX)
The research team used the National Science Foundation's Very Large Array radio telescope in New Mexico to monitor faint radio emission from the supernova for a...
AI tool mines Hubble archive for hundreds of strange cosmic objects
Jan 29, 2026 (SPX)
Most of the newly cataloged anomalies are galaxies in the midst of mergers or interactions that display distorted shapes or long, trailing streams of stars and ...
Runaway massive stars mapped across the Milky Way
Jan 29, 2026 (SPX)
Runaway stars are stars that travel through space at unusually high speeds and gradually drift away from the regions where they formed. For decades, astronomers...
Webb sharpens view of dark matter shaping the cosmos
Jan 28, 2026 (SPX)
The new map, created with observations from NASA's James Webb Space Telescope and published in Nature Astronomy, traces dark matter in a region of sky in the co...
Sulfur ring molecule in galactic cloud links space chemistry to life
Jan 26, 2026 (SPX)
The discovery stands out because astronomers had previously only identified relatively small sulfur compounds in space, typically with six atoms or fewer. Sulfu...
China Sky Eye tracks binary-triggered fast radio burst activity
Jan 19, 2026 (SPX)
Fast radio bursts are powerful millisecond flashes of radio emission that arrive from distant galaxies and typically show nearly 100 percent linear polarisation...
Iron bar of hot plasma revealed inside Ring Nebula
Jan 19, 2026 (SPX)
The Ring Nebula, also known as Messier 57 and NGC 6720, is a planetary nebula in the constellation Lyra formed when a Sun-like star expelled its outer layers as...
Early universe dark matter born red hot before cooling
Jan 14, 2026 (SPX)
The study, published in Physical Review Letters, examines how dark matter might have been produced during a period in cosmic history known as post inflationary ...
Superheavy-lift rockets like SpaceX's Starship could transform astronomy by making space telescopes cheaper
Jan 10, 2026 (SPX)
A month later, a rival rocket company, Blue Origin, flew its almost-as-large New Glenn rocket all the way to orbit and sent spacecraft on their way to Mars. Whi...
Barred spiral galaxy spotted 11.5 billion years in the past
Jan 09, 2026 (SPX)
The team's analysis places COSMOS-74706 at roughly 11.5 billion years in the past on the cosmic timeline, showing that barred spirals were already in place by t...
Jets from black hole drive record coronal gas stream in nearby galaxy
Jan 09, 2026 (SPX)
In most galaxies, highly energized gas associated with active black holes remains confined within several tens of parsecs of the central black hole, but in VV 3...
Milky Way stars mapped as major source of ghost particle flux at Earth
Jan 09, 2026 (SPX)
Researchers at the University of Copenhagen have developed the most detailed model so far of neutrinos produced by stars across the Milky Way and of how many of...
Jet from galaxy black hole drives vast stream of super heated gas into space
Jan 08, 2026 (SPX)
The observations show super heated gas erupting from both sides of the galaxy in the form of two elongated nebulae powered by an active supermassive black hole ...
Dark matter neutrino link may ease cosmic tension
Jan 08, 2026 (SPX)
The study examines how such interactions could influence the formation of galaxies and other large-scale structures, addressing a known mismatch between predict...
Milky Way black hole flare leaves X ray echoes in nearby gas cloud
Jan 07, 2026 (SPX)
Michigan State University researcher Stephen DiKerby and colleagues used the XRISM space telescope to measure X rays from a giant molecular cloud close to the g...
Hubble confirms dark starless relic cloud near galaxy M94
Jan 06, 2026 (SPX)
Program principal investigator Alejandro Benitez-Llambay of the Milano-Bicocca University in Milan, Italy, described Cloud-9 as "a tale of a failed galaxy," not...
We have no idea what most of the universe is made of, but scientists are closer than ever to finding out
Jan 06, 2026 (SPX)
Mahapatra likens our understanding of the universe - or lack thereof - to an old parable: "It's like trying to describe an elephant by only touching its tail. W...
Hubble tracks Betelgeuse companion carving dense wake in giant star atmosphere
Jan 06, 2026 (SPX)
The team reported its results at the 247th meeting of the American Astronomical Society in Phoenix and in a study accepted for publication in The Astrophysical ...

Dec 30, 2025 (SPX)
The opening sequences guide viewers through the Milky Way, diving into colourful emission nebulae and dense star forming clouds where young stars are still embe...
Starlight falls short in giant star wind power
Dec 24, 2025 (SPX)
For decades, models of red giant winds have assumed that radiation pressure on newly formed dust grains is the main driver of mass loss in these evolved stars, ...
