Sentences with phrase «in supernova shock»

At least some of the mysterious particles are born in supernova shock waves, satellite data confirm

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.

This effect becomes even more apparent as the shock collides into the equatorial ring, as observed in Hubble Space Telescope images of the supernova.

A shock wave from that collapse will speed outward, violently expelling the star's outer layers in a massive explosion known as a supernova.

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.

«He has constructed an experiment, in which a hydraulic jump in a circular water flow exhibits pulsational asymmetries in close analogy to the shock front in the collapsing matter of the supernova core.»

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

Just over a decade ago, two teams used the supernovae to show that the universe is accelerating in its expansion due to the influence of dark energy, a shocking discovery that thrust type Ia supernovae into the astrophysical limelight.

Shocks in supernova explosions are thought to be the main source of cosmic rays — very high energy charged particles from space.

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

Shock waves in supernova remnants are thought to be responsible for accelerating many of these particles.

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.

Scientists have attributed the patterns observed in supernova explosions and ejecta from shock - induced metal melt to RM instability.

HEFT will map the hard X-ray emission from supernova remnants to investigate issues of stellar nucleosynthesis (through the mapping of radioactive Titanium) and study the origin and acceleration of cosmic - rays (through mapping the continuum hard X-rays produced in the same shocks that produce the cosmic - rays).

Although absorption in ionized hydrogen suggests that the SNR is about 13,000 to 16,000 ly (4,000 to 5,000 pc) away (Schwarz et al, 1995), analysis of its optical proper motion and modelled shock velocity provides a distance of about 7,500 ly (2,300 pc)(more at T. Joseph W. Lazio's Tycho's Supernova Remnant).

For about two weeks the star could be seen in daylight, but at the end of November it began to fade and change color, from bright white over yellow and orange to faint reddish light, finally fading away from visibility in March, 1574, having been visible to the naked eye for almost 16 months (more about Brahe's «acid tongue and silver nose,» the cultural shock of the «new star,» and how supernovae create high - energy radiation from Wallace H. Tucker).

The shock wave from the supernova can initiate star formation in other interstellar clouds.

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.

These supernovae have a characteristic shockwave called the «shock breakout,» which was captured for the first time in optical light by Kepler.

NASA (Shock rings around Supernova 1987A)-- larger image While primordial supernovas created much of the heavier elements such as iron found in the Solar System, Sol orbits the galactic core without frequent crossings of the spiral arms where life - threatening supernovas are more common.

Now, a research team led by the Kavli Institute for Particle Astrophysics and Cosmology (KIPAC) at Stanford University and SLAC has discovered evidence that cosmic rays are born in the shock waves of distant supernovae.
