Scientists have discovered evidence of large quantities of biosignature chemicals — only known to be made by life on Earth — on an exoplanet more than 100 light-years away. It could be the most promising sign yet of alien life. Astronomers have detected the most promising signs yet of a possible biosignature on the exoplanet K2-18b, which orbits its star in the so-called habit

It was the first human spaceflight in more than 60 years that didn't feature a male crewmember. Blue Origin and Katy Perry just made history. Jeff Bezos' aerospace company launched its NS-31 mission today (April 14), sending the pop star and her five female crewmates on a brief mission to suborbital space. Liftoff occured at 9:30 a.m. EDT (1330 GMT) from Blue Origin's West Texas launch s
