It looked like nothing—then scientists found a world 10x the size of Jupiter Astronomers have uncovered a massive, hidden exoplanet nestled in the dusty disc of a young star—MP Mus—by combining cutting-edge data from the ALMA observatory and ESA’s Gaia mission. Initially thought to be planet-free, the star’s surrounding disc appeared deceptively empty. But new observations and a telltale stellar “wobble” pointed to a Jupiter-sized gas giant forming within the disc’s obscured gaps. This marks the first time a planet in such a disc has been detected using these tools, opening the door to finding more young worlds that have so far evaded detection.

100 ghost galaxies may be orbiting the Milky Way—and we’re just now uncovering them New supercomputer simulations suggest the Milky Way could be surrounded by dozens more faint, undetected satellite galaxies—up to 100 more than we currently know. These elusive "orphan" galaxies have likely been stripped of their dark matter by the Milky Way’s gravity and hidden from view. If spotted by next-gen telescopes like the Rubin Observatory’s LSST, they could solidify our understanding of the Universe’s structure and deliver a stunning validation of the Lambda Cold Dark Matter model.

These mysterious stars could glow forever using dark matter Imagine a star powered not by nuclear fusion, but by one of the universe’s greatest mysteries—dark matter. Scientists have proposed the existence of “dark dwarfs,” strange glowing objects potentially lurking at the center of our galaxy. These stars might form when brown dwarfs absorb enough dark matter to prevent cooling, transforming into long-lasting beacons of invisible energy. A specific form of lithium could give them away, and if detected, these eerie objects might reveal the true nature of dark matter itself.

This tiny rice plant could feed the first lunar colony In a bold step toward sustainable space travel, scientists are engineering a radically small, protein-rich rice that can grow in space. The Moon-Rice project, led by the Italian Space Agency in collaboration with three universities, aims to create crops that thrive in microgravity while boosting astronaut nutrition and well-being.

This interstellar comet may be a frozen relic from before the Sun A newly discovered comet, 3I/ATLAS, may be the most ancient visitor ever detected, potentially older than our solar system itself. Unlike previous interstellar objects, this ice-rich comet seems to originate from the thick disk of the Milky Way, a region filled with ancient stars. First spotted in July 2025, it’s already showing signs of activity and could help scientists understand more about galactic chemistry and the origins of planetary systems.
