Artist impression of Quaoar's rings. Credit: Paris Observatory A group of researchers has discovered a previously unknown ring system around a dwarf planet located at the outer edge of the solar system. This ring system is unique in that it orbits much farther out than other known ring systems, which challenges current theories about the...
A series of green laser beams seen over Hawaii in January. (National Observatory of Japan) Above the islands of Hawaii on January 28th, a green laser was seen piercing the evening sky, silently tracing a course towards the horizon such as a stutter in the Matrix's code. The scene was captured on camera from a telescope atop...
Positions of the 20 SNRs with detected diffuse UV emission (red squares) and of the 5 SNRs with likely, but confused, diffuse emission (blue squares), overlaid on the image of the Andromeda Galaxy in the F148W filter. Credit: Leahy et al, 2023 Utilizing the AstroSat satellite, astronomers from the University of Calgary, Canada, have identified...
Credit: Awareness Act. Last year, astronomers discovered Comet C/2022 E3 ZTF, which had not been visible until then due to its distance from Earth. However, it is now approaching Earth, and soon it will be making its closest approach in 50,000 years. Astronomers have stated that this will be the only chance to see it...
Two interacting galaxies viewed from the Hubble Space Telescope. Credit: NASA/ESA/Hubble Heritage Team A research study led by the College of Southampton has shown how supermassive black holes (SMBHs) are feeding off gas clouds that reach them by traveling hundreds of thousands of light yrs from one galaxy to another. A worldwide team of scientists has...

Right panel: MeerKAT discovery observation. Credit: Ridolfi et al., 2021. Utilizing the MeerKAT radio telescope, astronomers from the Max Planck Institution for Radio Astronomy (MPIfR) in...
This artist's conception shows a late-stage galaxy merger and its two newly-discovered central black holes. The binary black holes are the closest together ever observed in multiple wavelengths. Credit: ALMA (ESO/NAOJ/NRAO); M. Weiss, NRAO/AUI/NSF Astronomers have found two ghostly Goliaths en route to a catastrophic meeting. The newly found pair of supermassive black holes are...
Credit: Unsplash/CC0 Public Domain New information from the James Webb Space Telescope (JWST) have revealed that the structures of galaxies in the early universe were much more diverse and also mature than previously known. Researchers recently compared photos of hundreds of galaxies taken by JWST for the Cosmic Evolution Early Release Science (CEERS) Survey with...
Portion of the spectrum of HD 213258. Credit: Mathys et al, 2022 Utilizing the Canada-France-Hawaii Telescope (CFHT), astronomers have observed a chemically peculiar star called as HD 213258. In the outcome, they found that HD 213258 is a quickly oscillating, strongly magnetic Ap star. The finding is reported in a paper released on December 24...
