Probably the most well-known result of the Earth’s magnetic field is the Aurora Boralis and Austral Australia (Northern and Southern Lights). When charged particles from the solar wind run into the Earth’s magnetic field, they can occasionally emit spectacular light displays. For many years, scientists have thought that the charged …

In a very detailed survey of the southern sky using radio waves, astronomers have mapped millions of previously unknown galaxies outside the galaxy. The Rapid ASKAP Continuous Survey (or RACS) has firmly placed CSIRO’s Australian SKA Pathfinder Radio Telescope (ASKAP) on the international astronomy map. While past surveys have taken …

There are traces of ancient dust at the bottom of the South Pacific Ocean that has changed the Earth’s atmosphere, and new research suggests it came from beneath Argentina’s ice-age glaciers. Wrapped by heavy westerly winds about 20,000 years ago, these microscopic minerals would have circulated almost all over the …

Astronomers have obtained the highest resolution of infrared images near the Kerina Nebula, a thick cloud of dust and gas in which stars are actively forming. Gemini in Chile is incredible to see the newly obtained images obtained from the South Telescope. It’s also useful for understanding stellar nurseries and …
