Astronomers have discovered an extraordinary celestial system containing a runaway pulsar fleeing the scene of a massive stellar supernova explosion. What makes this system even more spectacular is the fact that it should be “forbidden” in the empty region of the Milky Way in which it was found. The system, given the name “Calvera” after the villain in the 1960 …

Red supergiant DFK 52 and its surroundings as seen by ALMA. The vast, complex bubble blown by this extreme star is about 1.4 light-years across, thousands of times wider than our Solar System. ALMA measures light invisible to the human eye, with a wavelength of around 1.3 millimeters, emitted by molecules of carbon monoxide and silicon monoxide. Thanks to the …

A glowing hand stretches across the cosmos, with its palm and fingers sculpted from the wreckage of a massive stellar explosion. The eerie structure is part of the nebula MSH 15-52, powered by pulsar B1509-58 — a rapidly spinning neutron star that is only about 12 miles (20 kilometers) in diameter. By combining radio data from the Australia Telescope Compact …

EVANSTON, Ill. — Astronomers have observed what they are calling a new type of supernova, which has provided an unparalleled glimpse into what happens deep within a star just before it explodes. A study detailing the surprising discovery published Wednesday in the journal Nature. Massive stars are like celestial onions: The outermost layers are made up of lightweight elements such …

Recently, the Hubble Space Telescope captured a before-and-after image of a star exploding brightly. With the images one year apart, the contrast shows how bright a supernova is, and how that brightness fades over time. What is it? The supernova explosion, designated as SN 2018gv, is found in the spiral galaxy NGC 2525. According to NASA, Hubble began observing the …

An international team led by Weizmann Institute of Science and Northwestern University scientists says it has discovered a never-before-seen core of a supernova, a massive exploding star, that was rich in heavy elements such as silicon, sulfur and argon. The star’s outer layers were stripped away suddenly, and the blazing inner core — the heart of the massive star, dubbed …

Read More »NEW YORK (AP) — Scientists for the first time have spotted the insides of a dying star as it exploded, offering a rare peek into stellar evolution. Stars can live for millions to trillions of years until they run out of fuel. The most massive ones go out with a bang in an explosion called a supernova. Using telescopes that …
