The skies are about to get a new star as a result of a cosmic cataclysm
Any night now, the astrophysicists tell us, a new star will appear in the night sky—about as bright as the North Star—the result of a cosmic explosion in a distant constellation millennia ago.

New tidally tilted pulsator discovered by astronomers
Astronomers have detected a new tidally pulsator star (TTP) by analyzing the data from NASA's Transiting Exoplanet Survey Satellite (TESS). The newfound pulsator, designated TIC 435850195, belongs to the rare class of tri-axial ...
Astronomers detect black hole 'starving' its host galaxy to death
Astronomers have used the NASA/ESA James Webb Space Telescope to confirm that supermassive black holes can starve their host galaxies of the fuel they need to form new stars. The results are reported in the journal Nature ...

Huge gamma-ray burst collection 'rivals 250-year-old Messier catalog,' say astronomers
Hundreds of gamma-ray bursts (GRBs) have been recorded as part of an enormous global effort so extensive it "rivals the catalog of deep-sky objects created by Messier 250 years ago", astronomers say.

Combination and summary of ATLAS dark matter searches within 2HDM+a framework
In the 1930s, Swiss astronomer Fritz Zwicky observed that the velocities of galaxies in the Coma Cluster were too high to be maintained solely by the gravitational pull of luminous matter. He proposed the existence of some ...

Do we live in a shell universe?
The universe might not be as you think. Until recently, the Lambda Cold Dark Matter model seemed to have a lock on cosmology. Like earlier Big Bang models, it supposes that the universe expanded from a hyperdense state and ...
New IW And-type star discovered by astronomers
A team of Chinese astronomers has performed photometric observations of a dwarf nova known as Karachurin 12. As a result, they have found that Karachurin 12 is an IW And-type star. The discovery was detailed in a research ...
Observational study supports century-old theory that challenges the Big Bang
