Spinning black hole swallowing star explains superluminous event
more »
An extraordinarily brilliant point of light seen in a distant galaxy, and dubbed ASASSN-15lh, was thought to be the brightest supernova ever seen. But new observations from several observatories, including ESO, have now cast doubt on this classification. Instead, a group of astronomers propose that the source was an even more extreme and very rare event -- a rapidly spinning black hole ripping apart a passing star that came too close.

Antarctic site promises to open a new window on the cosmos
more »
Antarctica might be one of the most inhospitable regions on the planet, but it is a mecca for astronomers. Its cold, dry air enables observations that can't be done elsewhere on Earth. The South Pole has hosted telescopes for decades. Now, researchers are eyeing a new location -- Dome A, which offers a unique opportunity to study the universe at little-explored terahertz radio frequencies.

ALMA finds compelling evidence for pair of infant planets around young star
more »
New ALMA observations contain compelling evidence that two newborn planets, each about the size of Saturn, are in orbit around a young star known as HD 163296. These planets, which are not yet fully formed, revealed themselves by the dual imprint they left in both the dust and the gas portions of the star's protoplanetary disk.

The origin of linear magnetoresistance: Exotic or classical?
more »
New materials sometimes exhibit spectacular resistance phenomena, though the explanation does not always prove to be exotic. Physicists have demonstrated that a simple physical model is sufficient to explain the phenomenon of linear magnetoresistance, outlines a new report.
