Strange radio waves from the centre of the galaxy

In the West Australian desert, an array of radio telescopes has spotted strange radio signals emanating from somewhere near the heart of the Milky Way. These signals don’t fit any known patterns produced by familiar radio sources such as pulsars, quasars or radio galaxies. Instead, astronomers think they could come from a new type of … Continue reading Strange radio waves from the centre of the galaxy

New and detailed atlas of the skies

A new radio telescope in outback Western Australia has just created an atlas of the southern sky in record-breaking time, demonstrating that detailed all-sky surveys can now be done in weeks instead of years. Over just 300 hours, CSIRO’s Australian Square Kilometre Array Pathfinder (ASKAP) mapped three million galaxies, one million of which we’d never … Continue reading New and detailed atlas of the skies

SpaceWatch: A matter about dark matter

Dark matter theories may lack something Astronomers suspect something is missing in current theories of how dark matter behaves. An international team has uncovered an unexpected discrepancy between observations of the dark matter concentrations in a sample of massive galaxy clusters and theoretical computer simulations of how dark matter should be distributed in clusters. The … Continue reading SpaceWatch: A matter about dark matter

Fred Watson: Greatest Science Cinematography

  On a cold, wintery day there was nothing better than to sit down and check out this year’s SCINEMA International Science Film Festival from the comfort of my own living room. To be honest, I’m not a great movie watcher, but I do know when I’ve seen something worthwhile, and the two films I … Continue reading Fred Watson: Greatest Science Cinematography

Cosmos Q&A: Eye and AI on the sky

As Cosmos reported this week, new technology continues to change the already hi-tech world of space watching, with the likes of AI, deep learning and computational modelling complementing and expanding on the data that comes from telescopes and satellites.  We spoke with Alan Duffy, an astrophysicist at Australia’s Swinburne University of Technology, about what we … Continue reading Cosmos Q&A: Eye and AI on the sky

Why astronomy matters in times of crisis

In an international emergency like the present one, you might expect the science of the stars to be the last thing on people’s minds. The problems facing both individuals and governments are infinitely more pressing than events in the depths of space. People are suffering unprecedented hardships. Yet throughout history, astronomy has shown extraordinary resilience … Continue reading Why astronomy matters in times of crisis
