A 3-gram (0.1 ounce) sample of the Hypatia stone. Researchers found a consistent pattern of 15 elements in the Hypatia stone. The pattern is completely unlike anything in our solar system or our solar neighborhood, in the Milky Way. Credit: Romano SerraNew chemistry ‘forensics’ indicates that the stone named Hypatia from the Egyptian desert could be the first physical evidence found on Earth of a supernova type Ia explosion. These rare supernovas are some of the most energetic events in the universe.This is the conclusion…

In fresh trouble for electric two-wheelers, the Central Consumer Protection Authority (CCPA), which comes under the Union Consumer Affairs Ministry, has sent notices to Pure EV and Boom Motors after their e-scooters exploded in April.The consumer watchdog is also examining more cases of e-scooter fires and will serve similar notices to other electric vehicle (EV) makers too, reports CNBC TV 18.Pure EV and Boom Motors along with Ola Electric, Jitendra EV and Okinawa Autotech, recalled faulty batches after the EV fire…

Artist impression of an exploding white dwarf. Credit: University of TübingenWhen stars like our Sun run out of fuel, they contract to form white dwarfs. Such dead stars can sometimes flare back to life in a super-hot explosion and produce a fireball of X-ray radiation. A research team from several German institutes including Tübingen University and led by Friedrich-Alexander-Universität Erlangen-Nürnberg (FAU) has now observed such an explosion of X-ray light for the very first time.“It was to some extent a fortunate…

The supernova known as 2014C took place eight years ago—but scientists are still watching and learning from its aftermath. The very faintly visible explosion is shown circled in red.

The brief, yet colossal eruption of a dead star undergoing a nova explosion has been captured by one of the most powerful X-ray instruments in space.The joint German-Russian eROSITA telescope, aboard the Spektr-RG space observatory in the L2 Lagrange point (yes, Webb's home), caught for the first time what is known as the 'fireball' phase of a classical nova. This X-ray data has finally confirmed via observation a 1990 prediction about the physics of novae.  The nova in question is known as YZ Reticuli, discovered on 15…

This artist’s illustration shows supernova 2013ge, with its companion star at the lower right. The companion star is impacted by the blast wave from the supernova, but not destroyed. Over time astronomers observed the ultraviolet (UV) light of the supernova fading, revealing a nearby second source of UV light that maintained brightness. The theory is that the two massive stars evolved together as a binary pair, and that the current survivor siphoned off its partner’s outer hydrogen gas shell before it exploded.…
