Astronomers have observed an unusually bright flare on the outskirts of a distant galaxy, triggered by a supermassive black hole destroying a star. This discovery raises new questions about the origins of such phenomena outside the centers of galaxies.
Astronomers have, for the first time, observed the early stages of the explosion of the supernova SN 2026gzf in a distant galaxy located 500 million light-years from Earth. What makes this event unique is the unusually weak shock wave and the absence of any signs of a gamma-ray burst, which calls for further investigation.
Astronomers have discovered a star with an extremely primitive chemical composition, containing almost no iron, in the dwarf galaxy Pictor II. Studying this star helps scientists better understand the properties of the first generations of stars in the Universe.
Astronomers are studying the recently discovered rare hybrid nova, Nova Vulpeculae 2024, which exhibits characteristics of two different types of novae. This discovery is helping scientists gain a deeper understanding of the evolution of such celestial objects.
New images of the Cat's Eye Nebula, captured by the Hubble and Euclid telescopes, reveal its intricate structure and dynamic nature. This data will help astronomers gain a deeper understanding of such cosmic objects.
Astronomers have observed an unusual dimming of the star ASASSN-24fw, caused by the passage of an unknown object. The reasons behind this phenomenon remain unclear, and various hypotheses are currently being considered.
Astronomers have, for the first time, observed the disappearance of a massive star in the Andromeda galaxy without a supernova explosion—the star transformed directly into a black hole. This discovery will help scientists better understand the final stages of stellar evolution and aid in the search for new black holes throughout the Universe.
The Hubble Telescope has captured the most detailed image yet of the Egg Nebula—the closest and youngest known nebula of its kind. This photograph will help astronomers gain a deeper understanding of the processes involved in the formation of such nebulae.
