This is one of the new images of the Sun from ESA’s Solar Orbiter’s closest approach on March 26, 2022. Credit: ESA Astronomers have proposed a concept mission to fly a neutrino observatory into orbit around the sun to get a better picture of what’s going on in the sun’s core. Astronomers have very few tools to peer into the heart of the sun. Fortunately, the constant nuclear reactions taking place in the sun’s core as hydrogen combine to form helium release a relentless flood of neutrinos. Neutrinos are tiny, ghost-like particles that almost never interact with matter. On Earth we’ve built giant detectors to catch the occasional neutrino. Astronomers have used these neutrinos to understand the nuclear processes taking place inside the sun and to probe the edges of known physics. But our observatories on Earth are basically limited because our planet is so far from the sun. So what if we took the ne...

American researchers have developed a light sailing craft designed to fly over Mars and collect data. Non-motorized aircraft are built to use natural winds pattern around Mars to operate for days. The aircraft is equipped with flight, temperature and gas sensors, as well as cameras. It is designed to collect data about the atmosphere and physical structure of the Red Planet. A working model of the sailplane was developed by engineers at the University of Arizona. The team is partnered on the project with Alexandre Kling, a research scientist with the American space agency NASA. Kling said in a statement the sailing craft could be a valuable resource in helping NASA study important areas above the Martian surface. “You have this very important and critical piece at the planetary boundary layer like in the first few kilometers above the ground,” he said. “This is where all the exchange between the surface and the atmosphere takes place.” Kling works at NASA...
