Astronomers have caught a black hole far from the center of its home galaxy ripping a star to shreds — providing, for the first time, direct evidence of a rogue supermassive black hole in action. The event, named AT2024tvd, took place approximately 600 million light-years from Earth. Despite weighing about a million times the mass of our sun, the black hole wasn't found at the center of its host galaxy, where such giants typically reside.

A dazzling new image from the European Southern Observatory's VLT Survey Telescope in Chile has revealed an unusual cosmic tale unfolding 6,000 light-years away in the Serpens constellation. The snapshot features the vivid red nebula Sh2-46 — also known as Gum 80 — lit up in a fiery hue due to intense radiation coming from a brilliant blue-white star nestled at its heart.

A few weeks after astronomers claimed they found the “strongest evidence yet” for alien life on a distant planet, independent follow-up analyses are casting serious doubt on the result. On 17 April, University of Cambridge researchers grabbed headlines when they said they had used data from NASA’s giant JWST telescope to detect biosignatures—gases that on Earth are produced by marine algae—in the atmosphere of K2-18b, an exoplanet 2.6 times the size of Earth some 120 light-years away.

Earth's atmosphere pulses in sync with the sun's fiery outbursts, according to new research, indicating that our planet is more sensitive to solar activity than previously thought. Solar flares — sudden, intense eruptions of energy from the sun — are already known for their dramatic effects on our planet: dazzling auroras, disruptions to radio communications, GPS interference, and, in extreme cases, power grid failures.
