Scientists captured the first detailed image of a supernova's initial shape, revealing it was not perfectly spherical but stretched along one axis, challenging previous models of stellar explosions. The observation was made using the Very Large Telescope shortly after the explosion of SN 2024ggi in galaxy NGC 3621, providing new insights into the mechanics of star death.

Astronomers have discovered a record-breaking, unusually long gamma-ray burst, GRB 250702B, which lasted about a day and originated from a galaxy billions of light-years away. Its peculiar duration and repeated signals challenge existing theories about such cosmic explosions, suggesting a possible involvement of an intermediate black hole and a white dwarf, but the exact cause remains unknown.

Astronomers have observed the first visual evidence of a star exploding twice, supporting the theory that some Type Ia supernovae result from a double-detonation process involving white dwarfs, which has implications for understanding cosmic expansion and dark energy.

The most powerful space explosion, known as BOAT, emitted the largest blast of gamma radiation ever recorded and gave rise to a black hole 2.4 billion light-years away. Despite its unprecedented strength, new findings reveal that the event was surprisingly ordinary in terms of the resulting supernova, challenging previous assumptions about the relationship between gamma-ray bursts and supernovae.

NASA's James Webb Space Telescope captured the most powerful space explosion ever seen, nicknamed the BOAT, which resulted in the birth of a black hole. The event, the biggest burst of gamma radiation ever recorded, was initially thought to be unusually bright, but new research suggests it was not any brighter than previous supernovae. Despite hopes of finding evidence of the supernova producing heavy elements like platinum and gold, no such evidence was found, leaving the origin of these elements still a mystery. The study has been published in the journal Nature Astronomy, and future observations with the James Webb Space Telescope will further explore the production of heavy elements by similar events.

The most powerful space explosion ever recorded, GRB 221009A, was surprisingly ordinary in terms of its associated supernova, challenging previous expectations. Despite its extreme brightness, the explosion did not show signs of heavy element production, suggesting that extremely energetic gamma-ray bursts like the BOAT may not be responsible for creating these elements. Future observations with the James Webb Space Telescope will help determine if other gamma-ray bursts produce heavy elements.

A massive explosion is expected to occur in a binary star system 3,000 light years from Earth, making it visible to amateur astronomers between now and September. The event, known as a recurrent nova, occurs every 80 years when a white dwarf and a red giant in the system trigger a runaway nuclear explosion, creating a temporary bright spot in the night sky. Astronomers are eagerly anticipating this rare event, which will provide valuable insights into the dynamics of these binary star systems.

Scientists have warned that a rare type of space explosion known as a kilonova, which occurs when two neutron stars or a neutron star and a black hole collide and merge, could potentially eradicate life on Earth for thousands of years. The explosion would release gamma rays that could strip electrons from atoms, destroy the ozone layer, and expose the planet to lethal doses of ultraviolet radiation. However, the chances of such an event occurring within a dangerous distance of Earth are very low. Researchers are still studying kilonovas due to their rarity and rapidity.
