A red supergiant star has blown an enormous bubble of gas and dust, baffling astronomers. The structure, as massive as the Sun and larger than our solar system, formed in a sudden eruption thousands of years ago. Why the star didn’t explode as a supernova remains a mystery. Discovery of a Vast Stell...

Astronomers identify Type Ia supernovae interacting with gas as a new source of cosmic dust, offering insights into the process of dust formation in elliptical galaxies. Cosmic dust—like dust on Earth—comprises groupings of molecules that have condensed and stuck together in a grain. But the exact n...

The discovery of a neutron star in Supernova 1987A illuminates the life cycle of stars and the cosmic origins of essential elements. An international team of astronomers including UCL’s (University College London’s) Professor Mike Barlow has discovered the first conclusive evidence that a neut...

It looks like the same mechanism that breaks up airplane contrails might be at play in forming the clumps of hydrogen gas that ring the remnant of supernova 1987A. Physicists often turn to the Rayleigh-Taylor instability to explain why fluid structures form in plasmas, but that may not be the full s...

Astronomers detect long-sought compact object within the remnant of Supernova 1987A In February 1987, the closest supernova to Earth in almost 400 years exploded onto the scene. Designated Supernova 1987A (SN 1987A), it resulted from the death of a massive star in the Large Magellanic Cloud, a dwarf...

Observations of SN 2023ixf in 2023 led to surprising findings regarding cosmic ray production by supernovae, with potential implications for understanding cosmic ray origins and acceleration mechanisms. In 2023, a nearby supernova offered astrophysicists an excellent opportunity to test ideas about ...

Located 240 million light-years away, UGC 9684 is recognized for its regular production of supernovae and new stars, earning the spotlight in recent Hubble observations due to its dynamic characteristics and importance in astronomical studies. The celestial object showcased in this week’s Hubb...

This summer, astronomers worldwide are eagerly anticipating a nova event in the constellation Corona Borealis, visible to the naked eye. This eagerly awaited event, which occurs roughly every 80 years, promises to engage both professional astronomers and amateur stargazers, providing significant obs...

Elusive temporary star described in historical documents recreated using new computer model, shows it may have recently started generating stellar winds. A supernova remnant from 1181, resulting from two colliding white dwarfs, was analyzed using historical records and modern astronomy. The discover...

Observations of the youngest known core collapse supernova in the Milky Way provide insights into the conditions that lead to the formation and destruction of molecules and dust within supernova ejecta. The SETI Institute announced the latest findings from the James Webb Space Telescope (JWST) of th...

UGC 11861, a barred spiral galaxy nestled in the constellation Cepheus, lies 69 million light-years from Earth. This galaxy is not only a breathtaking sight captured by the Hubble Space Telescope but also a hotbed of cosmic activity. Resting near the center of the northerly constellation Cepheus, hi...

Recent research highlights common envelope jet supernovae as pivotal in generating elements heavier than lanthanides, revising earlier beliefs that neutron star mergers were the primary sites. This discovery opens new avenues for understanding the cosmos and guides future astrophysical studies. In a...

Researchers have innovated polymer synthesis using a Tesla coil to initiate polymerization through a remote spark discharge, successfully synthesizing high-purity polymers and opening new avenues in material synthesis with electromagnetic waves. Researchers at the University of Tsukuba have devised ...

Researchers exploring neutrinos in dense environments like supernovae and neutron star mergers discovered that these “ghost particles” can become entangled, sharing quantum states and evolving chaotically. This new understanding of neutrino behavior, confirmed by numerical simulations, s...
