Jet from giant galaxy M87: Computer modelling explains black hole observations

Posted: 04 Nov 2021 11:01 AM PDT

An enormous jet of particles emitted by the giant galaxy M87 can be observed astronomically in various wavelengths. Scientists have developed a theoretical model of the morphology of this jet using complex supercomputer calculations. The images from these calculations provide an unprecedented match with astronomical observations and confirm Einstein's theory of general relativity.

Astronomers make most distant detection yet of fluorine in star-forming galaxy

Posted: 04 Nov 2021 09:13 AM PDT

A new discovery is shedding light on how fluorine -- an element found in our bones and teeth as fluoride -- is forged in the Universe. Astronomers have detected this element in a galaxy that is so far away its light has taken over 12 billion years to reach us. This is the first time fluorine has been spotted in such a distant star-forming galaxy.

Astronomers have analyzed observations of Algol. They argue that Algol has many companion stars which have not been detected from earlier observations.

Laboratory will illuminate formation, composition, activity of comets

Posted: 03 Nov 2021 12:08 PM PDT

Researchers have developed a laboratory to simulate comets in space-like conditions. The goal of the Comet Physics Laboratory is to understand the internal structure of comets, as well as how their constituent materials form and react. Many of the lab's future experiments will involve creating sample comet materials with differing compositions. By testing those materials in the space-like chamber, the researchers can compare each sample to what has been observed on actual comets.
