NASA estimated the cost of a flight would be around $50 million per seat.

Launched last week, TESS will scan 200,000 close and bright stars, seeking new planets and possibly livable worlds. Here's a roundtable discussion with 2 scientists on the TESS mission.

The visitor center at NASA’s Goddard Space Flight Center in Greenbelt, Maryland, is offering virtual field trips for groups looking for STEM (science,

"This white dwarf is so old that whatever process is feeding material into its rings must operate on billion-year timescales," said one of the scientists involved in the discovery.

How the worlds closest to our own can look a lot more like our home.

The Apollo 11 Saturn V space vehicle climbs toward orbit after liftoff from Pad 39A at 9:32 a.m. EDT on July 16, 1969.

This is exactly what NASA planetary scientists did, using data from the agency's former mission to Mercury. This colourful view of Mercury was produced by using images from the color base map imaging campaign during MESSENGER's primary mission [Credit: NASA/Johns Hopkins University Applied Physics…
