Cosmic Illusion Revealed: Gravitational Lens Magnifies Supernova

A team of researchers led by Robert Quimby at the Kavli Institute for the Physics and Mathematics of the Universe (Kavli IPMU) has announced the discovery of a galaxy that magnified a background, Type Ia supernova thirtyfold through gravitational lensing. ... [Published Science Daily - 7 hours ago]

A spiral home to exploding stars

DescriptionIn this new Hubble image, we can see an almost face-on view of the galaxy NGC 1084. At first glance, this galaxy is pretty unoriginal. Like the majority of galaxies that we observe it is a spiral galaxy, and, as with about half of all spirals, ... [Published European Space Agency - Apr 04 2014]

3D Model of Supernovae Provides details of Complexities inside It

.. Scientists have created a new 3D computer model in a bid to gain a better insight into a star's dying moments. A star ends it life with a gigantic explosion, known as supernovae. This cosmic phenomenon also tells us the reason behind existence of heavier ... [Published TopNews United States - Mar 20 2014]

Astronomers Find Solar Storms Behave Like Supernovae

Researchers at UCL have studied the behaviour of the Sun's coronal mass ejections, explaining for the first time the details of how these huge eruptions behave as they fall back onto the Sun's surface. In the process, they have discovered that coronal ... [Published Scientific Blogging - Mar 04 2014]

Supernova scrutiny: Astronomers look inside the heart of a dying star for the first time

For the first time ever astronomers have been able to look inside the heart of an exploding star, using a space telescope to peer into the radioactive corpse of Cassiopeia A, a star that was once eight times the size of the Sun. "This has been a holy ... [Published The Independent - Feb 20 2014]

Quotes

...brighter than Type Ia usually have higher temperatures (bluer colors) and larger physical sizes (and thus slower light curves)," Quimby continues, "New physics would thus be required to explain PS1-10afx as an intrinsically luminous supernova."
"Heat is not the only modifier of organic matter in the cosmos. Pressure is also a major agent of change and the variation in pressure in space is extreme" says Montgomery. Supernovae can reach maximum pressures of 103–106 GPa, hundreds of billions of times higher than terrestrial atmospheric pressure...

"We still have the concentric circles, with the heaviest elements in the middle and the lightest elements on top, but it is if someone put a paddle in there and mixed it around" , said Arnett
