Hints emerge of giant planet orbiting Alpha Centauri A
Astronomers using the NASA ESA CSA James Webb Space Telescope have gathered strong evidence pointing to a giant planet circling Alpha Centauri A, one of the Sun-like stars in the closest stellar system to Earth. Located just 4 light-years away, Alpha Centauri comprises the binary pair Alpha Centauri A and B along with the red dwarf Proxima Centauri, which already hosts three confirmed planets. Paperclip probe could journey to nearby black hole within a century
It may sound like pure science fiction - a spacecraft no heavier than a paperclip racing toward a black hole at near-light speed - but astrophysicist Cosimo Bambi of Fudan University believes it could be achievable within decades.
Writing in the journal iScience, Bambi presents a conceptual plan for sending a gram-scale nanocraft to a nearby black hole to probe the fabric of space-time and Baby star blast warps its own disk in rare cosmic feedback loop
Astronomers in Japan have identified a rare feedback loop in which a young star's explosive outflow has ricocheted back, striking and warping the very disk of gas and dust from which the star formed. The unexpected discovery may force scientists to rethink the conditions under which stars and planetary systems develop.
Stars form when molecular clouds collapse under gravity, spinning into NASA Hubble captures sharpest view yet of interstellar comet 3I/ATLAS
A team of astronomers has used NASA's Hubble Space Telescope to obtain the clearest image yet of interstellar comet 3I/ATLAS, enabling the most precise size estimates so far. The icy nucleus may measure up to 3.5 miles (5.6 kilometers) in diameter, but could be as small as 1,000 feet (320 meters). Even Hubble cannot directly see the nucleus, but its observations provide tighter constraints than Tracking the climate-driven shift in Antarctic plankton from space
Combining 25 years of space-based data with ocean sampling, scientists have uncovered a change in the microscopic organisms that underpin the Southern Ocean’s food chain and carbon storage.
No Earth-like atmosphere on TRAPPIST-1 d
The exoplanet TRAPPIST-1 d intrigues astronomers looking for possibly habitable worlds beyond our solar system because it is similar in size to Earth, rocky, and resides in an area around its star where liquid water on its surface is theoretically possible. But according to a new study using data from the NASA/ESA/CSA James Webb Space Telescope, it does not have an Earth-like atmosphere.

For military space, what tasks should be automated?
SALT LAKE CITY – It’s easy to talk about satellite autonomy but significant work remains to determine exactly which tasks should be handled by machines, according to speakers at the 2025 Small Satellite Conference.
