Magnetic pumping pushes plasma particles to high energies
The solar wind is not a calm summer breeze. Instead, it is a roiling, chaotic mess of turbulence and waves. There is a lot of energy stored in this turbulence, so scientists have long thought that it heats the solar wind. However, the heating expected from turbulence is not the heating observed. Scientists at the University of Wisconsin -- Madison have a new idea about what heats the solar wind, a theory called magnetic pumping. (2018-11-05)

Black holes ruled out as universe's missing dark matter
If dark matter consists of a plethora of primordial black holes, then their gravitational lensing -- magnifying and brightening distant objects -- should be detectable. UC Berkeley physicists analyzed 740 known supernovas to find the handful that should have been magnified and brightened by black holes, and found none. This puts a strong upper limit, 40, on the percent of dark matter that can consist of black holes, and suggests that none of it is. (2018-10-02)

Amateur astronomer captures rare first light from massive exploding star
First light from a supernova is hard to capture; no one can predict where and when a star will explode. An Argentinian amateur astronomer has now captured on film this first light, emitted when the exploding core hits the star's outer layers: shock breakout. Subsequent observations by UC Berkeley astronomers using the Lick and Keck observatories helped identify it as a Type IIb supernova that slimmed down from 20 to 5 solar masses before exploding. (2018-02-21)

Amateur astronomer captures rare first light of massive exploding star
An amateur astronomer in Argentina captured images of a distant galaxy before and after the supernova's 'shock breakout' - when a supersonic pressure wave from the exploding core of the star hits and heats gas at the star's surface to a very high temperature, causing it to emit light and rapidly brighten. Victor Buso's chances of such a discovery, his first supernova, is estimated at one in 10 million or perhaps even as low as one in 100 million. (2018-02-21)

Astronomers reveal secrets of most distant supernova ever detected
An international team of astronomers led by the University of Southampton has confirmed the discovery of the most distant supernova ever detected -- a huge cosmic explosion that took place 10.5 billion years ago, or three-quarters the age of the Universe itself. (2018-02-19)

Meteoritic stardust unlocks timing of supernova dust formation
Dust is everywhere -- not just in your attic or under your bed, but also in outer space. To astronomers, dust can be a tool to study the history of our universe, galaxy, and Solar System. For example, observations indicate that type II supernovae -- explosions of stars more than ten times as massive as the Sun -- produce copious amounts of dust, but how and when they do so is not well understood. (2018-01-18)

Astronomers detect 'whirlpool' movement in earliest galaxies
Astronomers have looked back to a time soon after the Big Bang, and have discovered swirling gas in some of the earliest galaxies to have formed in the universe. These 'newborns' -- observed as they appeared nearly 13 billion years ago -- spun like a whirlpool, similar to our own Milky Way. This is the first time that it has been possible to detect movement in galaxies at such an early point in the universe's history. (2018-01-10)
