Closest black hole to Earth discovered just 1 000 lightyears away

The closest black hole to Earth-- lying just 1 000 lightyears away-- has been discovered by a team of astronomers from the European Southern Observatory (ESO) and other institutes. Scientists say more similar black holes could be found in the future. "We were...

First ever image of a black hole

Scientists using the Event Horizon Telescope (EHT) have reportedly obtained the first image of a black hole. The image shows a bright ring formed as light bends in the intense gravity around a black hole that is 6.5 billion times more massive than the Sun. The...

Black hole magnetic field engines detected for the first time

Astronomers have detected magnetic fields outside the black hole horizon at the center of Milky Way for the firs time, Harvard Smithsonian Center for Astrophysics (CfA) announced on December 3, 2015. Magnetic fields of this type have long been considered to serve as...

Hawking still in the dark on black holes

In a new online paper titled Information Preservation and Weather Forecasting for Black Holes, the 72-year-old scientist Stephen Hawking says, "There are no black holes — in the sense from which light can't escape to infinity." The

Chandra catches our supermassive black hole rejecting material

Astronomers using NASA's Chandra X-ray Observatory have taken a major step in explaining why material around the giant black hole at the center of the Milky Way Galaxy is extraordinarily faint in X-rays. This discovery holds important implications for understanding

A look inside a "Black Hole" - Researchers solved the mystery of X-ray light emitted from black holes

Assumptions about how stellar-mass black holes create their highest-energy light have been confirmed by the recent study by NASA astronomers, John Hopkins University and the Rochester Institute of Technology. Lead scientist Jeremy Schnittman, an astrophysicist at

Supernova remnant W49B

NASA's Chandra X-ray observatory may have found galaxy's youngest black hole

Observations of a rare supernova remnant by Chandra X-ray observatory indicates the presence of our galaxy’s youngest black hole 26,000 light-years away from Earth. Scientists studied highly distorted remnant of what they believe was a rare supernova explosion

Gamma pulsar

The Quantum Guide - Pulsars

A pulsar is a neutron star that emits beams of radiation that sweep through Earth's line of sight. Like a black hole, it is an endpoint to stellar evolution. The "pulses" of high-energy radiation we see from a pulsar are due to a misalignment of the neutron star's

Swift satellite discovers rare X-ray Nova and a black hole

NASA's Swift satellite has discovered a stellar-mass black hole toward center of our Milky way galaxy. With its advantageous X-rays detection ability, Swift found a rare Nova as a result of high energy X-ray outburst in mid-September; leading to discovery of black

Star wandered too close to the black hole and got sucked in by the huge gravitational forces

Astronomers have spied a star's swan song as it is shredded by a black hole. Researchers suspect that the star wandered too close to the black hole and got sucked in by the huge gravitational forces. The star's final moments sent a flash of radiation hurtling towards

Supergiant Elliptical Galaxy Found to Harbor Most Massive Known Black Hole in the Universe

Chandra space telescope recorded a stunning image showing effervescence of supermassive black holes at elliptical galaxy M87 in cluster Virgo.  Outbursts and deep sounds have been generated by the black hole for eons as it seems.The black hole at the center of the
