Using data from ESA's Extraterrestrial Planet Characterization Satellite (CHEOPS) and several other ESA and NASA missions, astronomers detected signs of extraterrestrial planets. Rainbow-like “glory effect” In…
The newly identified structures, called Shakti and Shiva, are between 12 billion and 1 billion years old, making them so old that they are even older…
Astronomers used NASA’s Chandra X-ray Observatory and NSF’s Carl G. Jansky Very Large Array (VLA) to locate H1821+643, the closest quasar hosted by a galaxy cluster,…
Astronomers using the Karl G. Jansky Very Large Array have observed long-lasting aurora-like radio bursts above sunspots. This discovery could help us better understand the behavior…
of new mapThis quasar, called Quaia, contains about 1,295,502 quasars from across the visible universe and could help astronomers better understand the properties of dark matter.…
Astronomers have proposed a new theory to explain why a mysterious population of white dwarfs has stopped cooling for at least 8 billion years. This diagram…
Astronomers are gemini north telescope measured a binary supermassive black hole located within the elliptical galaxy B2 0402+379. Artist's impression of the supermassive black hole binary…
Our Sun is within 300 parsecs (about 1,000 light-years) of a 2,700-parsec (about 9,000 light-years) long sinusoidal dense gas cloud known as the Radcliffe wave. The…
The three newly discovered moons (S/2023 U1, S/2002 N5, and S/2021 N1) are the faintest ever discovered around Uranus and Neptune using ground-based telescopes. Discovery image…
The black hole in the newly discovered quasar SMSS J052915.80-435152.0 (J0529-4351) accretes about 1 solar mass per day on top of its existing mass of 17…
Using new 21 cm radio observations made with NSF's Green Bank Telescope, astronomers have discovered that more than 250 clouds of neutral gas are blasting out…
The JuMBO 24 binary system resides in the Orion Nebula, a diffuse nebula located approximately 1,350 light-years away in the constellation Orion. Free-floating Jupiter-mass binary objects…
Using data from NASA’s Transiting Exoplanet Survey Satellite (TESS), astronomers discovered a habitable zone planet orbiting nearby red dwarf star TOI-715 every 19.3 days and characterized…
The odd radio sphere (ORC), a type of extragalactic astronomical source discovered in 2019, is actually a shell formed by galactic winds spilling from massive supernovae,…
30 Doradas BThis galaxy, also cataloged as NGC 2060, is discovered in the Large Magellanic Cloud, a small satellite galaxy of the Milky Way. At the…
Planets that are too close to their star (such as Venus) are too hot, and planets that are too far away (such as Mars) are too…

Removing the hydrogen-rich layer from a main-sequence star exposes the helium-rich core. Such stripped helium stars are known at high and low masses, but not at…
Recent observations of the young star DG Taurus reveal a smooth protoplanetary disk in which no planets have yet formed, suggesting that it is on the…
According to some researchers, the oldest of these stars is 1.5 billion years old, while the youngest is only 100 million years old. paper Published in…
