Before These Clouds Form Stars, They Form A Complex Network of Filaments
Researchers working with China's Five-hundred-meter Aperture Spherical radio Telescope (FAST) have revealed some of the complexity in a type of cloud in the ISM. They've detected a network of filaments in one Very High Velocity Cloud (VHVC). The observations hint at the complexity that can evolve in these clouds, all without the influence of gravity.
A New Fuel for Nuclear Power Systems Could Enable Missions to Mars and Beyond
To explore the unknown in deep space, millions of miles away from Earth, it’s crucial for spacecraft to have ample power. NASA’s radioisotope power systems (RPS) that rely on are a viable option for these missions and have been used for over 60 years. Now, NASA is testing a new type of RPS fuel that could become an additional option for future long-duration journeys to extreme environments.

How can the James Webb Space Telescope see so far?
Earth Sized Planet Discovered with Extreme 5.4 Hour Year
Astronomers have discovered an extraordinary world that defies everything we thought we knew about planets. TOI-2431 b, an Earth sized planet located just 117 light years away, races around its star so fast that it experiences over 1,600 "years" in the time it takes Earth to complete just one orbit. The discovery of this extreme world, with its distorted shape and ultra dense composition, is revolutionising our understanding of planetary systems and revealing just how bizarre and diverse worlds beyond our Solar System can be.
JWST Finds Plenty Of Low Mass Black Holes In The Early Universe
Black holes played a critical role in the formation of the early universe. However, astronomers have been debating for a long time just how critical, as the information we had about early black holes, which exist at high red-shifts, was relatively limited. A new paper from a group of researchers led by Sophia Geris at the University of Cambridge combined several spectra from the James Webb Space Telescope (JWST) to add some context to the formation of black holes early in the universe, and found that there are plenty of smaller ones lurking around, and lending credence to the idea that black holes of all sizes contributed to the formation of our modern universe.
Astronaut Fitness Gets a Boost with Adaptive Harness Design
What new exercise methods can be devised for astronauts in space under microgravity conditions? This is what a recent study conducted submitted to the 2025 Technology Collaboration Center’s (TCC) Wearables Workshop and University Challenge hopes to address as a team of Rice University engineering students developed a new type of space exercise harness that could make exercising under microgravity easier and more comfortable.
The JWST Might Have Found the First Direct-Collapse Black Hole
Stellar mass black holes are created by core-collapse supernovae. These occur when massive stars near the end of their lives collapse in on themselves and form a black hole. Supermassive black holes form through mergers with other massive black holes. But their could be a third kind, called direct-collapse black holes, and the JWST found evidence of one.
Do Supermassive Black Holes Play With Their Food?
Lightning might not strike twice, but black holes apparently do. An international group of researchers led by Tel Aviv University astronomers observed a flare caused when a star falls onto a black hole and is destroyed.
