1. Advanced radio telescope technology 'sifts' space for mysteries

   The first trial of an Australian-developed technology has detected mysterious objects by sifting through signals from space like sand on a beach.

2. Ingenuity measurements reveal surprising wind speeds on Mars

   One of my gripes with "The Martian" movie was the depiction of the winds on Mars. The lower air density means that the sort of high speed winds we might experience on Earth carry far less of an impact on Mars. During its 72 flights in the Martian air, NASA's Ingenuity helicopter took meticulous records of the conditions. A new paper has been released and reports upon the wind speeds on the red planet at various altitudes. Previous models suggested wind speeds would not exceed 15 m/s but Ingenuity saw speeds as high as 25 m/s.

3. Dwarf planet Ceres may have received organic material from space objects

   The organic material found in a few areas on the surface of dwarf planet Ceres is probably of exogenic origin. Impacting asteroids from the outer asteroid belt may have brought it with them.

4. Fast radio bursts appear to be caused by young neutron stars

   Fast radio bursts (FRBs) are one of the greater mysteries facing astronomers today, rivaled only by gravitational waves (GWs) and gamma-ray bursts (GRBs). Originally discovered in 2007 by American astronomer Duncan Lorimer (for whom the "Lorimer Burst" is named), these short, intense blasts of radio energy produce more power in a millisecond than the sun generates in a month.
