James Webb Space Telescope Detects Supernova From 11.4 Billion Years Ago
Astronomers using the James Webb Space Telescope (JWST) have identified AT 2023adsv, a supernova that occurred 11.4 billion years ago. This stellar explosion, from a star 20 times the size of the Sun, offers a glimpse into the early universe's unique stellar evolution. Part of the JWST Advanced Deep Extragalactic Survey, the event highlights how th...

Dead Star Caught Ripping Apart Planetary System in a Rare Incidence of Cosmic Cannibilism
The discovery was made by analysing archival data from NASA's Hubble Telescope and other observatories of the American space agency. Termed cosmic cannibalism, the observation helped shed light on the violent nature of the evolved planetary system and can help astronomers in understanding the makeup of newly forming systems.

'Tatooine' Planets Survive Violent Escapades Of Ageing Stars
Planets that revolve around two suns may surprisingly survive the violent late stages of the stars' lives, according to new research.

Violent Young Sun May Have Seeded Life on Earth: Study
Super-flares could've smashed nitrogen in Earth's air to yield a greenhouse gas, nitrous oxide, as well as hydrogen cyanide, which produces the building blocks of proteins.

A Violent Sun And A Sky Full Of Laughing Gas Could Have Led To Life On Earth
A coronal mass ejection hits Earth's atmosphere like a cannonball. The cloud of solar matter, created during storms on the sun, will fizzle through the thinnest parts of Earth's protective magnetic field and send waves of light dancing across the polar night skies.

As Homicides Surge, Forensics Stall in Jamaica
Corpses, the suspected victims of violent deaths, are wrapped in plastic bags or covered loosely in stained sheets. There is no air conditioning and the room quickly becomes sweltering as the tropical sun beats down on the metal roof. A black fly buzzes around the room amid the smell of decay.
