The Habitable Worlds Observatory Could Find More Very Massive Stars

Very massive stars (VMSs)have had a massive impact on the formation of our universe. However, there aren’t very many of them, with only around 20 known specimens in the Milky Way and Large Magellanic Cloud. Even observing those is difficult for the current generation of telescopes, which is where an unexpected technological champion might play a role. According to a new paper by Fabrice Martins of CNRS and a group of European and American researchers, the upcoming Habitable World Observatory (HWO) might be our most useful tool when it comes to finding these elusive giants.

Synthetic Biology Could Support Future Outposts on the Moon and Mars

As humanity sets its sights on long duration missions to the Moon, Mars, and beyond, keeping astronauts healthy will be as critical as building rockets or habitats. In the harsh environment of space, the human body faces challenges that Earth never prepared us for including isolation, microgravity, and radiation that disrupt the immune system, increasing the risk of infection, chronic inflammation, and disease. Interestingly, new research on HIV is revealing lessons that could help future explorers live sustainably, regenerate resources in closed-loop systems, and even produce custom medicine far from Earth.

Astronomers Use the Colours of Trans-Neptunian Objects' to Track an Ancient Stellar Flyby

Trans-Neptunian Objects (TNO) are some of our Solar System's lesser-known objects. They number in the thousands, and they get their name from their orbits. These dwarf planets that orbit the Sun at a greater average distance than Neptune does. Pluto is the group's most well-known member, having been demoted from planet to TNO in recent years.

Scientists Solve 400 Year Old Solar Mystery

Since Galileo first observed them through his telescope in the early 1600s, sunspots have fascinated scientists. These dark patches on the Sun's surface can persist for days or even months, but until now, researchers couldn't fully explain why they remained stable for such extended periods.

This Earth-sized Exoplanet is On a Death Spiral

Our circumstances here on the wondrous, life-supporting Earth can give us a false understanding of what the Universe is really like. But our blue-skied, temperate planet is the extreme exception when it comes to other worlds. There's nothing remotely like Earth in our Solar System, and exoplanet studies reinforce that idea. While some exoplanets have hints of habitability, most exoplanets are extremely inhospitable.

A Lunar Base Could Start with a Dome over a Crater Made of Regolith

When the first astronauts walked on the Moon as part of the Apollo Program, the concept of lunar habitats ceased being the stuff of science fiction and became a matter of scientific study. With several space agencies planning on sending crewed missions to the Moon in the coming decade, these plans have become the subject of scientific interest again. Structures that will enable a "sustained program of lunar science and development" is the long-term aim of NASA's Artemis Program. China and the ESA have similar plans with the International Lunar Research Station (ILRS) and the Moon Village.
