Recently discovered black hole is part of a nearby disrupted star cluster, study finds

Phys.org— European astronomers have investigated a recently detected black hole designated Gaia BH3. In their results, they found that the black hole is associated with a nearby disrupted star cluster known as ED-2. The finding is reported in a paper published April 17 on the preprint server arXiv.

Phys.org—Researchers advance detection of gravitational waves to study collisions of neutron stars and black holes. Researchers at the University of Minnesota Twin Cities College of Science and Engineering co-led a new study by an international team that will improve the detection of gravitational waves—ripples in space and time.

Phys.org—Warming Arctic reduces dust levels in parts of the planet, study finds. Climate change is a global phenomenon, but its impacts are felt at a very local level. Take, for example, dust. Dust can have a huge impact on local air quality, food security, energy supply and public health. Yet, little is known about how global climate change is impacting dust levels.

Big Think—Black holes are common. So where are the white holes?. In our Universe, the laws of physics tell us all the possibilities for what’s allowed to conceivably exist, but only by actually observing, measuring, and experimenting with our Universe itself can we determine what’s truly real. In Einstein’s general relativity, one of the very first possibilities that was ever discovered was for a black hole: a region of space with so much matter-and-energy in one place that from within that volume, nothing, not even light, could ever escape. The flip side of...
