If you are sneezing this spring, you are not alone. Every year, plants release billions of pollen grains into the air, specks of male reproductive material that many of us notice only when we get watery eyes and runny noses. However, pollen grains are far more than allergens - they are nature's time capsules, preserving clues about Earth's past environments for millions of years. Pol

Four NASA astronauts who recently returned to Earth from a mission aboard the International Space Station will take part this week in a welcome-home ceremony at NASA's space center in Texas. On Thursday, NASA astronauts Nick Hague, Suni Williams, Butch Wilmore and Don Pettit will be in Houston to participate in ceremonies to welcome them back to Earth and will share highlights from thei

Scientists investigating the origin of life suggest that primitive membranes may have influenced which biomolecules became foundational to life. Their study examines how the earliest cell membranes could have filtered molecules, favoring those used in modern biology. Cells are defined by their membranes, which regulate what substances can enter or leave. This control is especially relevant

Researchers at the International Centre for Radio Astronomy Research (ICRAR) have discovered that the spatial concentration of gas within galaxies plays a more critical role in star formation than the overall volume of gas present. The study, led by PhD candidate Seona Lee from The University of Western Australia's ICRAR node, utilized data from around 1,000 galaxies mapped by CSIRO's ASKA

New imaging technology developed by the Leibniz Institute for Astrophysics Potsdam (AIP) has enabled the Vacuum Tower Telescope (VTT) in Tenerife to capture unprecedented, high-resolution views of solar activity. The upgrade bridges a long-standing observational gap between wide-field solar monitoring and fine-structure resolution. The enhanced camera system restores the VTT's full observa

Earth - our tiny blue dot in the galaxy - is approximately 26,000 light years away from a fascinating and active region of the Milky Way called the Central Molecular Zone (CMZ). This region holds clues about how stars are born, how energy moves through our galaxy, and maybe even some details about dark matter. However, analyzing this area is challenging, because we do not have a clear top-

Exolaunch has signed new multi-year launch agreements with SpaceX, ensuring small satellite launch capacity through 2028 on Falcon 9 rideshare missions. The agreements span various orbital inclinations including sun-synchronous, mid-inclination, near-polar, and dawn-dusk trajectories to meet diverse mission requirements. These contracts allow Exolaunch to continue integrating and deploying

Paladin Space, a startup incubated at the University of South Australia's Innovation and Collaboration Centre, has introduced Triton, the first reusable space payload designed to capture and store multiple pieces of orbital debris for potential recycling. This breakthrough technology was demonstrated at a private event hosted by the ICC. The company's next objectives include securing early

One of the most profound open questions in modern physics is: "Is gravity quantum?" The other fundamental forces - electromagnetic, weak, and strong - have all been successfully described, but no complete and consistent quantum theory of gravity yet exists. "Theoretical physicists have proposed many possible scenarios, from gravity being inherently classical to fully quantum, but the

To create a crumbly crater rich in ice and chunky blocks soaked in layers of martian history – like this one recently observed by the European Space Agency’s Mars Express – follow this recipe:

1. Toss a space rock into Mars to form a classic circular base
2. Layer with molten lava 
3. Carve channels with liquid water
4. Chill to create ice, and freeze-thaw multiple times to slowly expand crater edges
5. Sprinkle generously with volcanic dust, and leave to set
6. Serve to hungry Mars fans!
