Star Explosion

Researchers have found a way to capture millimetre-wavelength light originating from a collision of a neutron star with another star. The flash emerging from this collision was among the most energetic short-duration gamma-ray bursts (GRBs) ever observed, according to the researchers.

Data received from the US space agency NASA's Chandra X-ray Observatory has revealed some fascinating features of a star, which was likely ejected from its birthplace due to a powerful explosion. The star, Zeta Ophiuchi, has a complicated past and is located some 440 light-years from Earth.

Astronomers have identified a black hole that not only is classified as dormant but appears to have been born without the explosion of a dying star, in a galaxy adjacent to the Milky Way. Black holes are extraordinarily dense objects with gravity so intense not even light can escape. Deemed a cosmic "needle in a haystack", the newly discovered ‘d...

In the latest research, astronomers from the University of Manchester have conducted the largest search for pulsar orbiting exoplanets. The survey included more than 800 pulsars which were analysed over the last 50 years. The researchers have tried to detect signals indicating the presence of planetary companions that had around 100 times more mass...

Astronomers have observed a star that not only survived a stellar explosion called a supernova, but emerged from it brighter than before the blast. This white dwarf is gravitationally locked in orbit with another star — a pairing called a binary system.

Astronomers have made an exciting new discovery, identifying a newborn pulsar that may possibly be only 14 years old. Scientists were finally able to observe the pulsar after the dense debris and bright energy emissions from the supernova explosion that created the pulsar finally thinned enough.

Researchers are hopeful that an extraterrestrial stone found in the Egyptian desert could help shed some light on these spectacular events. The stone is named Hypatia. The experts have a hypothesis that the Hypatia stone originated with a star – a red giant star collapsed into a white dwarf star, which eventually “ate” the other star.

A team of researchers have found that a quadruple star system – known as HD 74438 – could represent a new channel by which thermonuclear supernova explosions can occur in the universe. In their study published in the journal Nature Astronomy, they have shown that the gravitational effects of the outer binary system are changing the orbits of th...

IPL 2022: Prithvi Shaw has been explosive with the bat for Delhi Capitals and Sanjay Manjrekar hailed his aggressive approach.

In a first for astronomy, researchers were able to see in real time the death by explosion of a giant red star using ground-based telescopes. They saw the star, located 120 million light-years away from Earth in the NGC 5731 galaxy, self-destruct in a dramatic event and collapse in a type-2 supernova.

Chinese tennis star Peng Shuai said she was safe and well during a video call with the International Olympic Committee chief Sunday, the organisation said, amid international concern about her well-being after her explosive claims of sexual assault.

While all heavy metals have formed under extreme conditions inside stars or due to stellar explosions and collision of neutron stars, the question remains: when and why was the material ejected and whether heavy elements can be produced in any other way.

Ahead of the resumption of IPL in UAE, Royal Challenger Bangalore's star batsman AB de Villiers scored a brilliant hundred in a warm-up on Tuesday.

England vs India: Reactions poured in for Shardul Thakur for his brilliant 36-ball 57 even as the Indian team was bowled out for 191 on Day 1 of the fourth Test.

Scientists have recorded a cosmic explosion of gamma radiation from a collapsing star that challenges the established theory of gamma-ray bursts. The scientists said that these explosions occur when a massive star abruptly detonates and turns into a black hole.
