How Webb"s coronagraphs reveal exoplanets in the infrared
NASA's James Webb Space Telescope has many different observing modes to study planets orbiting other stars, known as exoplanets. One way in particular is that Webb can directly detect some of these planets. Directly detecting planets around other sta.....»»
Study reveals map of moon"s water near its south pole
A new study using the now-retired Stratospheric Observatory for Infrared Astronomy (SOFIA) has pieced together the first detailed, wide-area map of water distribution on the moon. SOFIA was a joint project of NASA and the German Space Agency at DLR......»»
Researchers introduce new optimal recommendations for fungicide resistance management
Fungicide application, while helpful in controlling plant diseases, has complicated limitations that may cost growers both peace of mind and quantity of yield. Plant pathogens which would otherwise be killed off by fungicides can evolve to avenge the.....»»
