Cosmic ‘speed camera’ reveals staggering speed of neutron star jets

How fast can a neutron star drive powerful jets into space? All of these properties will have an effect on how their jets are launched, making studies of neutron star jets particularly valuable. Our team, led by Thomas Russell from the Italian National Institute of Astrophysics in Palermo, conducted a new experiment to do this for neutron star jets. While …

Space telescope spies neutron star in the debris of famous supernova

Associated Press

Scientists have confirmed what became of a star that exploded in a stunning supernova visible to Earth more than three decades ago: It morphed into a neutron star, one of the oddest objects in the universe. But NASA’s Webb Space Telescope cut through the clutter by peering in infrared light and saw two telltale chemical signatures — argon and sulfur …

Mint Explainer: Why black holes are on India’s radar

Live Mint

If you watched Christopher Nolan’s 2014 movie Interstellar, you would be familiar with the word black hole, even if you do not fully understand what it means. In December 2021, the US-based National Aeronautics Space Agency launched the imaging X-ray polarimetry explorer mission to explore the remnants of supernova explosions, the particle streams emitted by black holes and other cosmic …

Scientists discover hidden population of stars that are the "bluest of blue"

Salon

Supernovae are rare events, yet they are critical to the inner workings of our universe and even our own biological makeup. “This happens naturally in a third of all massive stars through envelope stripping by a binary companion star.” This artist's impression shows how hot, brilliant and high-mass stars evolve. When asked to describe what these stars look like, Drout …

UK: Indian-Origin Astrophysicist, Professor Vik Dhillon, Shines Light on Universe's Mysteries

News 18

Professor Vik Dhillon, an Indian-origin astrophysicist from the University of Sheffield in the UK, is part of a team that has brought humanity closer to understanding how the heaviest chemical elements are created in the universe using a high-end camera. A kilonova, resulting from the fusion of two dense neutron stars, holds significance as it’s thought to be the source …

A bizarre star is either the lightest neutron star ever found, or something even weirder

Salon

When certain large stars use up all their nuclear fuel and die, they collapse and detonate, creating a supernova. Related How a watershed space explosion created trillions of tons of gold The smallest, lightest neutron star on record seems to be the obliquely named HESS J1731-347, discovered around 2007. Using X-rays and gravitational wave measurements, the astronomers determined HESS J1731-347 …

The illusion of being faster than light: how black holes are formed through the merging of neutron stars

The Hindu

Mooley, K.P., Anderson, J. From this, scientists, piecing together evidence from complementary measurements, surmised that the event they had observed was of two neutron stars merging and forming a black hole and, in the process, giving off light. This resolves the earlier fuzziness about what the source was and puts the source clearly as massive neutron stars merging to give …

Scientists have found the heaviest known neutron star

Live Mint

Astronomers have observed the most massive known example of an object called a neutron star, one classified as a "black widow" that got particularly hefty by gobbling up most of the mass of a stellar companion trapped in an unhappy cosmic marriage. The researchers said the neutron star, wildly spinning at 707 times per second, has a mass about 2.35 …

This black hole is wandering aimlessly in space. It's so fast it can travel from Earth to Moon in 3 hrs

India Today

Nearly a month after the Event Horizon Telescope snapped the first image of the black hole at the center of the Milky Way galaxy, astronomers have found a unique object in the universe — a free-floating black hole. Gravitational microlensing is a process where astronomers observe the light from a star far behind the black hole, which is momentarily brightened …

Gravitational Waves Caused by Collision of Neutron Star and Black Hole Detected

News 18

Scientists have for the first time detected gravitational waves — ripples in the fabric of space-time — produced by the collision of a neutron star and a black hole. The finding confirms that there are systems consisting of a neutron star and a black hole, and will help answer many questions about the cosmos, from star formation to the expansion …

Weeks after scientists confirmed that it was impossible for a black hole to decrease in size over time, signals from the collision of two neutron stars crashing into black holes have been detected for the first time. The most powerful gravitational waves are created when a star explodes asymmetrically, known as a supernova, or when two big stars orbit each …

Neutron star and a pulsar are stuck in a 'fiercely tight' orbit

Daily Mail

Astronomers have observed two collapsed stars spinning rapidly around each other in a doomed dance. A neutron star, the ultra-dense remains of a once vast star, is believed to be in a 'fiercely tight' orbit around a pulsar. It is highly unusual to observe two neutron stars orbiting each other in a binary system in this way, scientists say, and …
