Chemical rockets have taken us to the Moon and back, but traveling to the stars demands something more powerful. Space X’s Starship can lift extraordinary masses to orbit and send payloads throughout the Solar System using its chemical rockets but it cannot fly to nearby stars at thirty percent of light speed and land. For missions beyond our local region of space, we need something fundamentally more energetic than chemical combustion, and physics offers or in other words, antimatter.

Growing fresh lettuce and strawberries might sound mundane until you consider doing it on the Moon or Mars. An international team has created a roadmap for cultivating plants in space, addressing one of NASA's highest priority challenges for long duration missions. These aren't just about providing fresh food for astronauts, plants in space will recycle air and water, produce pharmaceuticals, process waste, and support mental health during years long journeys to distant worlds. With the first lu…

A team of scientists have detected electric discharges on Mars for the first time, confirming a phenomenon that was theorised for decades but never directly observed until now. The Perseverance rover's microphone accidentally captured the electromagnetic and acoustic signatures of sparks generated inside Martian dust devils, similar to the static shocks you might experience touching a metal door handle. This discovery changes our understanding of Mars's atmospheric chemistry and could explain lo…

Have scientists finally confirmed the existence of the first exomoon? This is what a recent study accepted for publication in Astronomy & Astrophysics hopes to address as a large international team of researchers investigated new methods for identifying an exomoon orbiting a gas giant exoplanet. This study has the potential to help scientists develop new methods for finding exomoons, the latter of which has yet to be confirmed.

What can equatorial jet streams on gas giant planets teach scientists about gas giant planetary formation and evolution? This is what a recent study published in Science Advances hopes to address as a team of scientists investigated the mechanisms of jet streams on gas giants (Jupiter and Saturn) and ice giants (Uranus and Neptune). This study has the potential to help scientists better understand not only the formation and evolution of giant planets in our solar system, but exoplanets, too.

How can star populations help astronomers re-evaluate the search for intelligent extraterrestrial life, also called technosignatures? This is what a recently submitted study hopes to address as a team of scientists investigated the parameters of identifying locations of technosignatures, also called extraterrestrial transmitters. This study has the potential to help astronomers constrain the criteria for finding intelligent life in both our galaxy and throughout the universe.

What can star variability—changes in a star’s brightness over time—teach astronomers about exoplanet habitability? This is what a recent study accepted to The Astronomical Journal hopes to address as a team of scientists investigated the interaction between a star’s activity and exoplanetary atmospheres. This study has the potential to help astronomers better understand how star variability plays a role in finding habitable exoplanets, specifically around stars that are different from our Sun.

Young stars buried deep in molecular clouds are bathed in ultraviolet radiation, but they shouldn't be. Protostars are too cold and dim to produce UV light themselves, yet James Webb Space Telescope observations of five stellar nurseries in Ophiuchus reveal its unmistakable signature affecting the surrounding gas. Astronomers tested the obvious explanation that nearby massive stars illuminate these birthplaces but subsequently ruled it out. The UV radiation must be coming from inside the star fo…

What is the importance of studying explosive volcanism on Venus? This is what a recent study published in the Journal of Geophysical Research: Planets hopes to address as a team of scientists investigated the potential altitudes of explosive volcanism on Venus. This study has the potential to help scientists better understand the present volcanic activity on Venus, along with gaining insight about its formation and evolution and other planetary bodies throughout the solar system and beyond.

The Nancy Grace Roman Space Telescope continues its inexorable march toward launch. It recently completed another series of tests that brings it a few steps closer to a launch pad in Florida. This time, the telescope was split into two separate parts - an inner portion and an outer portion, each of which went through separate tests throughout the fall.

A red giant orbiting a dormant black hole is spinning impossibly fast and contains chemistry that makes it look ancient when it's actually relatively young. By listening to faint vibrations rippling through the star, astronomers have decoded a violent secret, that this star likely collided with and absorbed another star billions of years ago, an explosive merger that left it chemically confused and rotating once every 398 days. The discovery reveals how even quiet black hole systems can have tur…

Ninety five years after Swiss astronomer Fritz Zwicky inferred its existence from galaxies moving impossibly fast, researchers may have detected the first direct evidence of dark matter, the invisible scaffolding that holds the universe together. Using gamma ray data from NASA's Fermi Space Telescope, a Japanese physicist has identified a halo of extremely energetic photons around the Milky Way's center that matches predictions for annihilating dark matter particles. If confirmed, humanity has f…

On Earth, Coronal Mass Ejections (CMEs) like the one we experienced earlier this month are aesthetic, even disruptive events, sending aurora southward and interrupting radio signals. But around other stars, they could prove lethal to life. This point was driven home by a recent CME detection from an M-class red dwarf star. This marks the first detection of an energetic Type II radio burst from a nearby star.

A planet’s habitability is determined by a confluence of many factors. So far, our explorations of potentially habitable worlds beyond our solar system have focused exclusively on their position in the “Goldilocks Zone” of their solar system, where their temperature determines whether or not liquid water can exist on their surface, and, more recently, what their atmospheres are composed of. That’s in part due to the technical limitations of the instruments available to us - even the powerful Jam…

In 2028, Hong Kong will launch its first dedicated lunar orbiter not to study craters or map minerals, but to monitor something far more urgent, the constant barrage of meteoroids slamming into the Moon's surface at thousands of kilometres per hour. As China prepares to build a permanent lunar research station, understanding this relentless bombardment has become a matter of safety for future astronauts living and working on the Moon.
