Star's death will play a mean pinball with rhythmic planets

Four planets locked in a perfect rhythm around a nearby star are destined to be pinballed around their solar system when their sun eventually dies, according to a study led by the University of Warwick that peers into its future.

The Great Debate of 1920: how it changed astronomy


The Great Debate of 1920: how it changed astronomy
April 28, 2021 at 10:10 am
In 1920, astronomers Harlow Shapley and Heber Curtis came together to take part in the Great Debate about the scale of the Universe. But what ultimately, was astronomy’s Great Debate about, and how did it change the way we look at the Universe?

Harlow Shapley, a 34-year-old journalist-turned-astronomer, must have been nervous when he climbed the stage in the Baird Auditorium of the Smithsonian Museum of Natural History in Washington, DC on 26 April 1920. Facing him was a crowd of fellow scientists and lay people alike.
On stage after Shapley would be his opponent in the Great Debate, eminent astronomer Heber Curtis – a man 13 years his senior, more experienced and eloquent at speaking, and who disagreed with Shapley on just about everything.

Science of spin - older stars rotate faster than expected

Science of spin – older stars rotate faster than expected
Sound waves trapped inside stars cause them to oscillate at particular frequencies. These vibrations are visible on the surface, and can be measured by astronomers using space telescopes. When a star is rotating these oscillation frequencies change slightly, making it possible to measure the star’s rotation by looking at how it’s surface changes over time.

Stars spin faster than expected as they age, according to a new study – which uses asteroseismology to shed new light on this emerging theory
All stars, like the Sun, are born spinning. As they grow older, their spin slows down due to magnetic winds in a process called ‘magnetic braking’. Research published in 2016 by scientists at Carnegie Observatories delivered the first hints that stars at a similar stage of life as the Sun were spinning faster than magnetic braking theories predicted.
