- by Stuart ClarkThe Moon may preserve a record of the raw ingredients that helped life begin on Earth. New analysis of lunar samples returned by Chinaβs Changβe missions has revealed a diverse suite of organic compounds embedded within the soil.
- by Stuart ClarkAstronomers may not need to see the same dark matter signal everywhere in the Universe to confirm its existence. A new theoretical study suggests that dark matter could consist of more than one type of particle, potentially resolving a long-standing observational puzzle.
- by Stuart ClarkORLANDO, FLORIDA. Iβm a space-crazed Canadian who has somehow seen 11 launches across four different rockets since 2009. Iβve witnessed missions with astronauts, interplanetary spacecraft and (inevitably) Starlink, across two continents. But Artemis II took me by surprise yesterday (April 1). The Space Launch System was so bright it was almost painful to look at. […]
- by Stuart ClarkA machine learning pipeline developed in the UK has validated over 100 exoplanets in NASAβs TESS data, revealing rare planetary systems and sharpening estimates of how common close orbiting worlds really are.
- by Emily Baldwin-FiebrichStrange X-rays from the naked eye star gamma-Cas have been confirmed to come from matter falling onto a hidden white dwarf companion, resolving a fifty-year astronomical mystery.
- by Stuart ClarkObservations of the nearby exoplanet L 98-59 d suggest it belongs to a previously unrecognised class of planet that features vast magma oceans and sulphur-rich atmospheres. The discovery hints that many more exotic planetary types may be waiting to be found.

This symbiotic binary system comprises a cool red giant and a sizzling white dwarf locked in a 44-year elliptical orbit. The enormous star pulsates in a roughly 390-day period, driving changes in temperature and brightness. It has onlyContinue […]
- by Mark ZastrowBy the time of Apollo 16βs April 16, 1972, launch, traveling to the Moon was, if not routine, at least a more confident affair. When astronauts John Young and Charlie Duke stepped off the ladder of the Lunar Module (LM) Orion onto the lunar surface, βthere wasnβt any tentative step,β Duke later said. βIt wasContinue […]
- by Jake ParksThe phenomenon of a Full Moon arises when our planet, Earth, is precisely sandwiched between the Sun and the Moon. This alignment ensures the entire side of the Moon that faces us gleams under sunlight. Thanks to the Moonβs orbit around Earth, the angle of sunlight hitting the lunar surface and being reflected back toContinue […]

- What Happens When Light Goes Boom? Part 2: The Crowd, the Molasses, and the Speed of Light (Sort Of)Before Brad Bradington can sprint down the red carpet, we need to understand the crowd. Specifically, we need to understand why a crowd of atoms and molecules slows down light β and why that creates a loophole that changes everything.
- Astronomers using data from the HobbyβEberly Telescope Dark Energy Experiment (HETDEX) have discovered tens of thousands of gigantic hydrogen gas halos, called βLyman-alpha nebulae,β surrounding galaxies 10 billion to 12 billion years ago.
- Engineers love a good practical challenge, especially when it comes to spaceflight. But thereβs one particular challenge facing the crewed missions of the near future that scares mission planners above almost all others – fire. For decades, weβve relied on a NASA test known as NASA-STD-6001B to screen material flammability for flight. But space is […]
- To say NASA has been undergoing some massive administrative changes lately is a huge understatement. One of the more concerning ones, according to a new paper at the 57th Lunar and Planetary Science Conference by Ari Koeppel and Casey Dreier of the Planetary Society, is the trend towards the Silicon Valley mindset of βmove fast […]

What he found β by refusing to dismiss something he didn't understand β turned into one of the most useful […]
- It's obvious that Earth is a planet. It's obvious that the Sun is a star. But for substellar objects like brown dwarfs, it's not so clear. Researchers are using the JWST to find a stronger dividing line between star and planet that depends on how they formed.

- Three Earth observation satellites, developed by the European Space Agency (ESA) with European partners, and due to launch later this year, have completed their functional and environmental tests and are ready to travel to the European spaceport in French Guiana. But first, journalists were invited to have one last look.
- Shrinking ice is arguably one of the most visible indicators of climate change β particularly in the Arctic. However, a European Space Agency-funded study used information from satellites to show that Antarctica is now experiencing similar dramatic changes, with profound consequences for key plankton species that underpin the regionβs marine food web.
