Moss spores withstand long term exposure outside space station
Saturday, 22 November 2025 06:57
Researchers have demonstrated that moss sporophytes can withstand nine months of direct exposure to outer space and remain reproductively viable upon return to Earth. The study, published November 20 in the journal iScience, tested the durability of Physcomitrium patens spores affixed to the outside of the International Space Station.

Researchers have detailed how a geomagnetic superstorm on May 10-11, 2024, shrank Earth's plasmasphere, a protective zone of charged particles, to just one-fifth of its normal size. The event, named the Gannon storm or Mother's Day storm, was the most powerful in over twenty years.

Smile is a brand-new space mission currently in the making. It will study how Earth responds to the solar wind and solar storms.
At the European Space Agency’s technical heart in the Netherlands, engineers have taken Smile through the final steps of testing and past its qualification and flight acceptance review – confirming that it is ready for launch in spring 2026.
This video let’s viewers peek into the testing and review process. It is the fourth episode in a series of short videos, and includes interviews with David Agnolon (ESA Smile Project Manager), Xia Jiayi (CAS Thermal

A new angle of study for unveiling black hole secrets
Friday, 21 November 2025 08:30
An international collaboration of physicists including researchers at Washington University in St. Louis has made measurements to better understand how matter falls into black holes and how enormous amounts of energy and light are released in the process.
The scientists pointed a balloon-borne telescope called XL-Calibur at a black hole, Cygnus X-1, located about 7,000 light-years from Ear Water production on exoplanets revealed by pressure experiments

Researchers led by Lawrence Livermore National Laboratory postdoctoral scientist Harrison Horn have demonstrated a pathway for producing water on sub-Neptune exoplanets. The team recreated the boundary conditions between hydrogen atmospheres and magma cores using a laser-heated diamond-anvil cell.
Horn stated, "Our experiments are the first to look at interactions between hydrogen and sili How smarter satellite teamwork can speed up connections in space

Low Earth orbit (LEO) mega-constellations are rapidly changing how we connect to the world, offering potential for faster communications, more accurate earth observation, and better disaster forecasting. Unlike previous, smaller satellite configurations, these mega-constellations involve thousands of satellites operating together, creating huge challenges for ground-based controllers struggling
