A group of international scientists, including an Australian astrophysicist, has used knowhow from gravitational wave astronomy (used to find black holes in space) to study ancient marine fossils as a predictor of climate change.
The research, published in the journal
Climate of the Past, is a unique collaboration between palaeontologists, astrophysicists and mathematicians - to improve the accuracy of a palaeo-thermometer, which can use fossil evidence of climate change to predict what is likely to happen to the Earth in coming decades. ....

Images of two iconic planetary nebulae taken by the Hubble Space Telescope are revealing new information about how they develop their dramatic features. Researchers from Rochester Institute of Technology and Green Bank Observatory presented new findings about the Butterfly Nebula (NGC 6302) and the Jewel Bug Nebula (NGC 7027) at the 237th meeting of the American Astronomical Society on Friday, Jan. 15.
Hubble s Wide Field Camera 3 observed the nebulae in 2019 and early 2020 using its full, panchromatic capabilities, and the astronomers involved in the project have been using emission line images from near-ultraviolet to near-infrared light to learn more about their properties. The studies were first-of-their-kind panchromatic ima ....

The core mass of the giant exoplanet WASP-107b is much lower than what was thought necessary to build up the immense gas envelope surrounding giant planets like Jupiter and Saturn, astronomers at Université de Montréal have found.
This intriguing discovery by Ph.D. student Caroline Piaulet of UdeM s Institute for Research on Exoplanets (iREx) suggests that gas-giant planets form a lot more easily than previously believed. ....

ESOblog - Five minutes with Adrian Russell

ESOblog
15 January 2021
How Adrian went from studying electrical engineering to working in astronomy
How the Director of Programmes contributes to ESO’s overall mission
What Adrian is most excited about in the future of astronomy
Adrian Russell looks back on how he got into astronomy and his path to becoming Director of Programmes at ESO. He shares with us what some of the most exciting new projects at ESO are, how the field of astronomy has changed in his career and what he is most looking forward to in the future.
Q. How did you get into astronomy?
A. When as a kid, I was just the right age when the Apollo moon landings were happening, so I got hooked on science very early on. ....

Study: X-Rays surrounding 'Magnificent 7' may be traces of sought-after particle

A new study, led by a theoretical physicist at Berkeley Lab, suggests that never-before-observed particles called axions may be the source of unexplained, high-energy X-ray emissions surrounding a group of neutron stars. ....
