Sentences with phrase «material in a supernova»

NuSTAR, a high - energy X-ray observatory, has created the first map of radioactive material in a supernova remnant called Cassiopeia A, or Cas A, to reveal how shock waves likely tear massive dying stars apart, the researchers said in a study, published in the Feb. 20 issue of Nature.

Specifically, the NuStar will map radioactive material in supernovae remnants in an attempt to study the origins of cosmic rays and extreme physics surrounding collapsed stars.

Not exact matches

Supernova 1987A appears to be creating a lot of this dust, suggesting that stellar explosions play a crucial role in seeding the cosmos with planet - building material.

The object is located in the center of a colorful cloud of material consisting of the remains of an ancient star that exploded as a massive supernova.

This calcium and other heavy elements could have been created in supernova explosions, and then incorporated into new stars, but the clusters as they are today are too small to keep hold of the material violently thrown out by supernovae.

Jon Mauerhan at the Steward Observatory in Tucson, Arizona, cites brightening on 26 September and material shooting out at 13,000 kilometres per second as sure - fire signs that SN 2009ip truly went supernova (arxiv.org/abs/1209.6320).

But if the supernova came from two white dwarfs colliding, its debris would have shot out unevenly, with some material flying faster in one direction than another.

Such stars end their lives in huge supernova explosions, ejecting their stellar materials outwards into space and leaving behind an extremely dense and compact object; this could either be a white dwarf, a neutron star or a black hole.

Bersten and her colleagues analyzed the light from the supernova and found that it matches models of the first phase of a supernova called the shock breakout phase, in which a shock wave from a massive star's collapse ricochets back from the star's core and pushes stellar material outward.

The instruments are expected to reveal details about gases trapped in galaxy clusters and wafting through supernova remnants as well as the turbulent streams of material spiraling away from black holes.

When they die, stars explode in supernovae, leaving behind a cloud of ejected material called a supernova remnant.

The collision of the supernova and the companion star shocked the supernova material, heating it to a blue glow heavy in ultraviolet light.

New supercomputer simulations of the crusts of neutron stars — the rapidly spinning ashes left over from supernova explosions — reveal that they contain the densest and strongest material in the universe.

The top candidates, the astronomers suggested, are a neutron star, possibly a highly - magnetic magnetar, surrounded by either material ejected by a supernova explosion or material ejected by a resulting pulsar, or an active nucleus in the galaxy, with radio emission coming from jets of material emitted from the region surrounding a supermassive black hole.

These supernova blasts send material and shock waves back into the nebular gas to create the Tarantula's glowing filaments also visible in this Hubble Space Telescope Heritage image.

As the white dwarf pulls material from a companion star, the temperature increases, eventually triggering a runaway reaction that detonates in a violent supernova that destroys the white dwarf.

Qingzhu Yin et al., «Diverse Supernova Sources of Pre-Solar Material Inferred from Molybdenum Isotopes in Meteorites,» Nature, Vol.

Most of the energy from the supernova turns into light when it hits this previously ejected material, resulting in a short, but brilliant burst of radiation.

Chandra had seen hot elements like iron and silicon and magnesium in the supernova cloud, and the shape of some of the material seemed to support the double - jets theory, vaguely following where the beams would be.

So the scientists set out to test two main theories: whether the supernova was caused in part by two narrow jets of material streaming out of either end of a rotating star, or whether it was the result of stuff «sloshing» around inside, leaving behind a lumpy shape.

Making their debut in Strange Attractor, Haroon Mirza's Cosmos (2016) and Supernova (2016) were created through a process of placing live peyote (Lophophora williamsii) on blank PCBs (material usually used to make circuit boards) and running electrical current through them.

Thus the interior of the Sun consists mostly of Fe, O, Ni, Si, S, Mg and Ca from the deep interior of the supernova — the same elements that comprise > 99 % of the material in ordinary meteorites.
