Sentences with phrase «around in supernova»

In fact, just before posting this Top Pictures list, a NASA press release came out saying the Fermi satellite has seen gamma rays from this object, which is another very strong piece of evidence for this; gamma rays are the very highest energy form of light, and should be made when subatomic particles bounce around in supernova shock waves.

well one hypothesis is that there is a massive black hole in the center of the universe that all the universe revolves around... once it sucks the whole or most of the universe into it... it can no longer hold it all together and it explodes creating a big explosion which dwarfs supernovas scattering elements and matter everywhere... and this expansion and contraction of the universe goes on for infinity with no beginning and perhaps no end.

But not only the spatial distributions of titanium and iron resemble those in Cas A. Also the total amounts of these elements, their expansion velocities, and the velocity of the neutron star are in amazing agreement with those of Cas A. «This ability to reproduce basic properties of the observations impressively confirms that Cas A may be the remnant of a neutrino - driven supernova with its violent gas motions around the nascent neutron star,» concludes H. - Thomas Janka.

It's so consistent that Type Ia supernovae are also called standard candles: Once astronomers find one in a region of space, they can use it as a baseline with which to compare other objects around it.

Shock waves in plasmas form around planets, stars and supernovas.

But if approved, K2 will be looking at a much more diverse region of sky with a wide range of astronomical and astrophysical phenomena: planets with short orbits around cooler stars (which, if in their star's habitable zone, could still harbor water); young, still - forming proto - stars, which could provide insight into star and planet formation; and supernovae and galaxy clusters.

The discovery made headlines around the world, as it was the first supernova visible to the unaided eye in almost 400 years.

Some are found in globular clusters, but most move in a huge cloud around the disk called the galactic halo, which has a luminous inner component defined by globular star clusters and other easily observable stars (with coronae of hot gas possibly expelled by supernovae and of high - velocity neutron stars) and an outer dark - matter component inferred from its gravitational impact on the Milky Way's spiral disk.

These pictures from the Hubble telescope's imaging spectrograph provide a new and unprecedented look at one of the most unique and complex structures in the universe — a light - year - wide ring of glowing gas around supernova 1987A.

It may only be around 1.7 to 2.1 million years old but will explode in a supernovae within only another one to three million years (Figer et al, 1998; STScI press release; and fact sheet).

Astronomers now believe, however, that GRBs seems so powerful because most of their energy is being beamed out of bi-polar jets in a brief burst, unlike the later stage of a supernova when neutrinos are emitted from all around the exploding star.

Astronomers spotted four separate images of the supernova in a rare arrangement known as an «Einstein Cross» around a galaxy within the cluster.

Indeed, GRBs appear to emit produce even more energy than supernovae or even quasars (which are energetically bright accretion disks and bi-polar jets around supermassive black holes that are most commonly found in the active nuclei of some distant galaxies and possibly even in the pre-galaxy period after the Big Bang).

Tycho's supernova remnant (SNR) is located around 7,500 light - years (ly) from Sol in the north central part (0:25:17 +64:8:37, J2000; and 0:25:13 +64:8.7, ICRS 2000.0) of Constellation Cassiopeia, the Lady of the Chair — north of Kappa Cassiopeiae and Shedar (Alpha Cassiopeiae); northeast of Caph (Beta Cassiopeiae); northwest of Gamma Cassiopeiae, Ruchbah (Delta Cassiopeiae), Achird (Eta Cassiopeiae), M103, and the Double Cluster, and southeast of Errai (Gamma Cephei).

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.

That suggests this particular star somehow survived the suicidal kaboom of a supernova, waited around 50 years, and exploded again, blowing up astronomers» ideas about stellar evolution in the process.

The youngest stars in the galactic region surrounding around the Solar Neighborhood are associated with «subgroup B1» of the Pleiades (M 45) stellar moving group, and astronomers hypothesize that the more massive stars born in this group may have already exploded as 20 or so supernovae over the past 10 to 20 million years as the entire group of stars moved through a nearby region of the Local Bubble (Berghoefer and Breitschwerdt, 2002).
