Scientists are following neon signs in a search for clues to one planetary system’s future and the past of another – our own solar system. Following up on a peculiar reading by NASA’s previous infrared flagship observatory, the now-retired Spitzer Space Telescope, the agency’s James Webb Space Telescope detected distinct traces of the element neon in the dusty disk surrounding the young…

NASA will hold off sending commands to its Mars fleet for two weeks, from Nov. 11 to 25, while Earth and the Red Planet are on opposite sides of the Sun. Called Mars solar conjunction, this phenomenon happens every two years. The missions pause because hot, ionized gas expelled from the Sun’s corona could potentially corrupt radio signals sent from Earth to NASA’s Mars spacecraft, leading to…

An analysis by NASA’s sea level change science team finds that if a strong El Niño develops this winter, cities along the western coasts of the Americas could see an increase in the frequency of high-tide flooding that can swamp roads and spill into low-lying buildings. El Niño is a periodic climate phenomenon characterized by higher-than-normal sea levels and warmer-than-average ocean…

When mechanical engineers accustomed to building one-of-a-kind spacecraft turn that focus to pumpkins, the results can be hauntingly good. The annual Halloween pumpkin-carving contest at NASA’s Jet Propulsion Laboratory in Southern California may be all in good fun, but to the 200 or so participants, it’s also serious business. Power tools are involved. Dioramas can incorporate…
