Laser research to boost deep space missions

Associate Francis Bennet will lead one of two new ANU projects to help propel deep space missions. Photo: Lannon Harley/ANU Canberra is one step closer to being Australia’s home to deep space laser communication, thanks to a government funding for researchers at The Australian National University (ANU). Two ANU projects have received funding from The … Read more

Meet the Martian meteorite hunters

Magnified view of the surface of the rock known as “Block Island”, on the surface of Mars. The image was taken by the microscopic imager onboard NASA’s Mars Exploration Rover Opportunity during the 1,963rd Martian day, or sol, of the rover’s mission on Mars (1 August, 2009). The triangular pattern of small ridges seen at … Read more

The three papers published on July … Read more

Scientists determine Mars crustal thickness

The two largest quakes detected by NASA’s InSight appear to have originated in a region of Mars called Cerberus Fossae. Scientists previously spotted signs of tectonic activity here, including landslides. This image was taken by the HiRISE camera on NASA’s Mars Reconnaisance Orbiter.

A new approach to analyzing the development of magnetic tangles on the Sun has led to a breakthrough in a longstanding debate about how solar energy is injected into the solar atmosphere before being released … Read more

Survey finds bullying and harassment systemic in astronomy and geophysics

Credit: Unsplash/CC0 Public Domain Results from a new survey of astronomers and geophysicists show that these sciences have a systemic bullying problem; one that is disproportionately worse for women and those from minority groups. In a survey carried out by the Royal Astronomical Society (RAS) last year of over 650 people in the field, 44% … Read more
