Earthlings get treated to just 13 or 14 Mercury transits a century.

An asteroid slightly smaller than the largest structure in the U.S. is slated to harmlessly zoom past Earth later this month.

The show will reach its peak on Monday night into the early morning hours of Tuesday.

The world's first female spacewalking team is making history high above Earth.

For the first time, NASA’s planet-hunting Transiting Exoplanet Survey Satellite (TESS) was able to watch the “cataclysmic phenomenon” of a star being torn apart by a black hole from beginning to end. Using follow-up observations from telescopes, astronomers were able to capture unprecedented data about the star-destroying events known as tidal disruptions.

Much like taking the family on a cruise or a trip to visit Mickey Mouse at Disney World, one California company believes that going to space will eventually become just another vacation option.
