Boosting gravitational wave detectors with quantum tricks

more »
A group of scientists will soon start developing a new line of technical equipment in order to dramatically improve gravitational wave detectors. If the scientists are able to improve the gravitational wave detectors as much as they 'realistically expect can be done,' the detectors will be able to monitor and carry out measurements in an eight times bigger volume of space than what is currently possible.

Veiled supernovae provide clue to stellar evolution

more »
At the end of its life, a red supergiant star explodes in a hydrogen-rich supernova. By comparing observation results to simulation models, an international research team found that in many cases this explosion takes place inside a thick cloud of circumstellar matter shrouding the star. This result completely changes our understanding of the last stage of stellar evolution.
