A world-first discovery of binary stars could be the first step in building a more complete picture of how our galaxy formed, according to astronomers from The Australian National University (ANU).   

The discovery is part of an ambitious 10-year program to scan the entire southern sky every few nights.  

Mars has experienced multiple ice ages, with each one leaving less ice than the last. By studying craters that serve as “ice archives,” researchers traced how the red planet stored and lost its water over hundreds of millions of years. These frozen records not only reveal Mars’ long-term climate history but also identify hidden resources beneath the surface that could provide drinking water, oxygen, and even rocket fuel for future astronauts.

A new study examines nickel and urea in early microbial habitats, showing how ancient cyanobacteria adapted to their chemical surroundings. By recreating Archean conditions in the lab, researchers uncovered clues about the delicate balances that shaped early cyanobacterial life. These findings hint at the unseen factors that may have set the stage for Earth’s first oxygen surge, providing a fresh perspective on the environmental and chemical conditions that allowed oxygen to accumulate in the atmosphere.

For the first time, astronomers have managed to capture a radio image showing two black holes orbiting each other. The observation confirmed the existence of black hole pairs. In the past, astronomers have only managed to image individual black holes.
