This artist's concept depicts astronauts and human habitats on Mars.

NASA’s plans for the 2020s include landing humans on the moon, detecting quakes on Mars, and defending Earth from deadly asteroids

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.
The Milky Way's spiral centers around a supermassive black hole. Scientists think that every galaxy has one at its center.

Alien civilizations may have explored the galaxy and visited Earth already, new study says. We just haven’t seen them recently.

The answer to the Fermi Paradox could be that aliens have already visited Earth, a study says. But it might have been more than 10 million years ago.
