On Aug. 7 and 8, NASA’s Nancy Grace Roman Space Telescope team assessed the observatory’s solar panels and a visor-like sunshade called the deployable aperture cover — two components that will be stowed for launch and unfold in space. Engineers confirmed their successful operation during a closely monitored sequence in simulated space-like conditions. On the first day, Roman’s four outer solar panels were deployed one at a time, each unfolding over 30 seconds with 30-second pauses between them. The visor followed in a separate test the next day. These assessments help ensure Roman will perform as expected in space. Roman is slated to launch no later than May 2027, with the team working toward a potential early launch as soon as fall 2026.
An international team of astronomers, co-led by researchers at University of Galway, has made the unexpected discovery of a new planet.
Detected at an early stage of formation around a young analog of our own Sun, the planet is estimated to be about 5 million years-old and most likely a gas giant of similar size to Jupiter.
Scientists have devised a new method for mapping the spottiness of distant stars by using observations from NASA missions of orbiting planets crossing their stars’ faces. The model builds on a technique researchers have used for decades to study star spots. By improving astronomers’ understanding of spotty stars, the new model — called StarryStarryProcess — can help discover more about planetary atmospheres and potential habitability using data from telescopes like NASA’s upcoming Pandora mission.
