In the eROSITA all-sky survey, scientists at the Max Planck Institute for Extraterrestrial Physics (MPE) have found an interesting repeating event. In an otherwise quiescent galaxy, an X-ray flare repeats every 220 days, ...

Using the Very Large Telescope (VLT) of the European southern Observatory (ESO), an international team of astronomers has observed a tidal disruption event known as AT 2022cmc. Results of the observational campaign, presented ...
In giant clusters of hundreds or thousands of galaxies, innumerable stars wander among the galaxies like lost souls, emitting a ghostly haze of light. These stars are not gravitationally tied to any one galaxy in a cluster.

Using the Five-hundred-meter Aperture Spherical radio Telescope (FAST), Chinese astronomers have inspected single-pulse behavior of a rotating radio transient (RRAT) known as PSR J0628+0909. Results of the study, published ...
For the first time, astronomers have spotted an exoplanet whose orbit is decaying around an evolved, or older, host star. The stricken world appears destined to spiral closer and closer to its maturing star until collision ...

Using the Southern African Large Telescope (SALT) and the Hubble Space Telescope (HST), an international team of astronomers have observed the dwarf galaxy HIPASS J1131–31, dubbed the "Peekabo Galaxy." The observational ...
A team led by UdeM astronomers has found evidence that two exoplanets orbiting a red dwarf star are "water worlds," planets where water makes up a large fraction of the volume. These worlds, located in a planetary system ...

Using ESO's Very Large Telescope (VLT) and the Hubble Space Telescope (HST), astronomers have inspected the globular cluster NGC 2808. Results of the study, published December 2 on the arXiv pre-print repository, shed more ...
It was a good year for research of all kinds as three men shared the Nobel Prize in physics for their work that showed that tiny particles separated from one another at great distances can be entangled. Alain Aspect, John ...
Around 2,500 years ago, a star ejected most of its gas, forming the beautiful Southern Ring Nebula, NGC 3132, chosen as one of the first five image packages from the James Webb Space Telescope (JWST).
