One of the first of its phylum to move around autonomously, its segmented tail swept from side-to-side to swim forward. Robotics researcher Richard Desatnik and colleagues identified the creature’s method of movem ...read more

While on Earth dust may mostly seem like a housecleaning nuisance, in the far reaches of space, it plays an exciting role in galaxy research. Although the existence of dust in space continues to be surrounded by intrigue, an international team of astronomers recently identified a type Ia supernova creating cosmic dust. A new study published in Nature Astronomy highlighted this previously unknown source of cosmic dust. Prior to the study, dust formation has been observed in supernovae, but only i ...read more
Does life exist elsewhere in the universe? If so, how do scientists search for and identify it? Finding life beyond Earth is extremely difficult, partly because other planets are so far away and partly because we are not sure what to look for.Yet, astrobiologists have learned a lot about how to find life in extraterrestrial environments, mainly by studying how and when the early Earth became livable.While research teams at NASA are directly combing the surface of Mars for signs of life, our ...read more
