The unexpected discovery of yellowballs by citizen scientists - in 2011 and 2012 - is shaking up astronomers' ideas about how stars and star clusters form. It's giving scientists a new window into the birth and evolution of young stars.
A popular theory of galaxy formation suggests that small galaxies merged to form larger ones. But galaxy C1-23152 - 12 billion light-years from Earth - apparently formed itself from gas in the early universe, via exceedingly rapid star formation.
Scientists already had Psyche classified as a metallic asteroid, but new observations with the Hubble telescope reveal its rusty surface and provide scientists with a unique view into what Earth-like planets are like during their formation.
All these years, NASA scientists have laboriously sifted through spacecraft images to identify and classify markings on Mars. Now they're using a new "classifier," powered by artificial intelligence. What takes a human 40 minutes takes the AI tool an average of just 5 seconds.
