New Revolutionary Theory of Dark Matter

  The Universe abounds with dark matter. Nobody knows what it consists of. Physicists from the University of Oslo have now launched a very hard mathematical explanation that could solve the mystery once and for all. SIGNS OF DARK MATTER: The image shows all the gamma rays recorded by the Fermi-LAT space probe as a map [continue reading]

Halo of Neutrinos Alters Physics of Supernovae

  Sparse halos of neutrinos within the hearts of exploding stars exert a previously unrecognized influence on the physics of the explosion and may alter which elements can be forged by these violent events. The titanic supernova, called SN 1987A, blazed with the power of 100 million suns for several months following its discovery on [continue reading]

Peering Into the Heart of a Supernova

  Each century, about two massive stars in our own galaxy explode, producing magnificent supernovae. These stellar explosions send fundamental, uncharged particles called neutrinos streaming our way and generate ripples called gravitational waves in the fabric of space-time. This image shows the inner regions of a collapsing, rapidly spinning massive star. The colors indicate entropy, [continue reading]

The Universe as a large particle physics experiment

  The lightest known subatomic particles in the Universe are now able to be more accurately scrutinised, in light of new astronomic research two years in the making.  3D simulated map of the universe showing halos of dark matter, some of which contain galaxies, generated using data from the WiggleZ Dark Energy survey. Astrophysicists used [continue reading]

Where Do the Highest-Energy Cosmic Rays Come From?

… Probably Not from Gamma-Ray Bursts.   The IceCube Collaboration, in which Berkeley Lab is a crucial contributor, has taken the first steps toward clearing up a cosmic mystery – and made the mystery more intriguing. The IceCube neutrino telescope encompasses a cubic kilometer of clear Antarctic ice under the South Pole, a volume seeded [continue reading]

New Cosmological Insights from the South Pole Telescope

Analysis of data from the 10-meter South Pole Telescope (SPT) is providing new support for the most widely accepted explanation of dark energy – the mysterious force that is responsible for the accelerating expansion of the universe. The data strongly support Einstein’s cosmological constant, even though the analysis was based on only a fraction of [continue reading]
