Recent Chandra X-ray Observatory observations have given insight into the behavior of the doomed star before it exploded, indicating that the predicted spectacular brightening of the circumstellar ring has begun. The supernova produced a shock wave that rumbled through the cavity, and recent data indicate that this event has started.
A recent study by NASA's Chandra X-ray Observatory suggests that the sun contains nearly three times more neon than previously believed. This discovery has solved a critical problem with understanding how the sun works. The increased amount of neon plays a crucial role in energy flow from nuclear reactions to space.
Astronomers observed a binary star system called RX J0806.3+1527, where the white dwarf pair has an estimated mass of one-half the sun and orbits at a rate consistent with gravitational wave predictions. The system is believed to be among the brightest sources of gravitational waves in the galaxy.
The Chandra X-ray Observatory has observed an X-ray outburst from the highly evolved red giant star Mira A, revealing a bridge of hot matter streaming between it and its companion white dwarf. The detection provides insights into interactions between binary systems, including those with a collapsed star.
Researchers have found that some galaxies and their central black holes underwent a phenomenal growth spurt, setting the stage for the birth of quasars. The study used Chandra X-ray observations to track the growth of supermassive black holes alongside the formation of stars in these galaxies.
Astronomers have detected periodic X-ray variations in a galaxy, suggesting a massive black hole with a mass of approximately 10,000 Suns. This finding provides strong evidence for the existence of intermediate-mass black holes, which could bridge the gap between stellar-mass and supermassive black holes.
A team of researchers has discovered a web-like system of gas clouds containing the missing baryons, which are thought to make up half of the universe's mass. The clouds, detected using X-ray telescope data, have temperatures of around 1 million degrees Celsius and are spread over vast distances.
Astronomers discovered a dense stellar graveyard with thousands of X-ray sources within 70 light years of the Milky Way's center. The discovery supports the idea that dynamical friction could create a massive population of stellar-mass black holes.
Astronomers discovered a record-breaking eruption of hot gas and cavities in galaxy cluster MS 0735.6+7421, fueled by a super massive black hole growing at an incredible rate. The event generated energy equivalent to hundreds of millions of gamma-ray bursts.
