This artist's rendition depicts NASA's Mars 2020 rover studying its surroundings.

NASA asked kids to name its new Mars rover, and the 9 finalists include Ingenuity and Fortitude. Now it’s time to vote.

NASA received over 28,000 essays from kids who want to name the next Mars rover. The robot will search for signs of alien life and stash samples.

NASA has big plans for the 2020s, from powerful new space telescopes to a hunt for alien life on a moon of Saturn. Here’s the timeline.

One year ago, NASA announced it would send astronauts back to the moon. Since then, new spacecraft and telescopes have filled its plans for the 2020s.

The human species will likely destroy itself long before the sun kills everyone on Earth, a Harvard scientists says

Scientist Avi Loeb wrote that we should colonize space to survive the sun's future expansion. But humanity might wipe itself out before then, he said.

NASA’s Voyager 2 spacecraft beamed back unprecedented data from interstellar space. It indicates a mysterious extra layer outside our solar syst...

Voyager 2 sent data about the edge of the solar system back to Earth. NASA scientists say it presents a new puzzle about what's beyond the heliopause.
Founder, Chairman, CEO and President of Amazon Jeff Bezos unveils his space company Blue Origin's space exploration lunar lander rocket called Blue Moon during an unveiling event in Washington, U.S., May 9, 2019.

Jeff Bezos’ space colonization plan was partially inspired by a 1976 book he read in high school that proposed connecting the Earth and the moon...

The book that inspired Jeff Bezos' space plan calls for building huge cylindrical tubes between Earth and the moon that would house space colonies.
This illustration by artist Pat Rawling shows the concept of a space elevator as viewed from the geostationary transfer station looking down the length of the elevator towards the Earth.

A giant elevator could connect Earth to space using current technology, experts say — here’s how that might work

A space elevator could make it easier, cheaper, and more sustainable to transport cargo and people from the surface of Earth or the moon to space.

Lunar landers must choreograph complex commands with little room for failure, while dealing with the moon's wonky gravity, uneven terrain, and dust.
This artist’s impression shows the planet K2-18b, its host star, and an accompanying planet in this system. K2-18b is now the only super-Earth exoplanet known to host both water and temperatures that could support life.

Scientists have discovered water vapor on a potentially habitable super-Earth for the first time. That planet is now our best bet for finding alien li...

K2-18b is our "best candidate for habitability," since it's the only known exoplanet with water vapor, an atmosphere, and potential for liquid water.
