    How future spacecraft might handle tricky landings on Venus or Europa

    If a spacecraft (like the one shown in this artist’s concept) ever touches down on Jupiter’s icy moon Europa, the craft will need to be especially agile in order to stick its landing. The best way to know a world is to touch it. Scientists have observed the planets and moons in our solar...

    NASA rover Perseverance on track for daredevil landing on Mars

    NASA’s Mars rover Perseverance, the most advanced robotic astrobiology lab ever flown to another world, neared the end of its seven-month, 293-million-mile (470-million-km) journey on Wednesday, hours away from a daredevil landing attempt on the Red Planet. With 370,000 miles (596,000 km) left...

    Disinfection spreads antimicrobial resistance

    During the COVID-19 pandemic, the use of disinfectants, alcohol-based hand sanitizers, and antiseptic hand wash has surged. As a precaution, many authorities have also increased chlorine dosage in wastewater disinfection to achieve a free chlorine residual concentration greater than 6.5 mg/liter...

    Scientists perform quantum teleportation with high accuracy across 44 kilometers

    Teleportation is the stuff of science fiction, but scientists are working on teleportation in the real world. They’re not teleporting people or products. Rather they’re working on quantum teleportation that could lead to the creation of a highly secure and extremely fast quantum Internet. As...

    Fujifilm, IBM unveil 580-terabyte magnetic tape

    When it comes to magnetic tape storage capacity, smaller is larger. That is, as the magnetic particles that store data become smaller, more data can be stockpiled in the same amount of space. Two leading tech giants put that simple principle to work and announced Wednesday that they have...

    Most detailed sunspot image to date captured by new solar telescope

    The Sun has a powerful magnetic field which slowly flips its poles every 11 years. Throughout this solar cycle, researchers monitor the Sun’s surface, with more sunspots indicating increased activity. As a new 11-year solar cycle began last year, researchers have been working to better capture...

    The Moon may hold much more water than we think

    Scientists have long suspected the Moon holds sizable reserves of water, secreted as ice in the deep cold of permanently shadowed craters near the poles. Two new studies tell us more about the possible extent of those reserves. One suggests the shadowy polar caches may cover an area equivalent...
