NASA's TESS exoplanet-hunting space telescope wraps up primary mission

By Mike Wall 12 days ago

TESS wrapped up its two-year primary mission on July 4, having discovered 66 confirmed alien planets and nearly 2,100 "candidates" that scientists still need to vet.

Extragalactic planets? Gravitational waves could help us find them.

By Charles Q. Choi 14 days ago

Thousands of Earthlike 'blanets' might circle the Milky Way's central black hole

By Rafi Letzter 18 days ago

Tens of thousands of planets like Earth and Neptune might orbit the giant black hole at the center of the Milky Way.

NASA's Nancy Grace Roman space telescope will send the hunt for exoplanets into warp speed

By Elizabeth Howell 20 days ago

A new NASA space observatory could push planet-hunting forward at warp speed by gathering data up to 500 times faster than the venerable Hubble Space Telescope does.

Most of the Milky Way's life-hosting planets may have formed early on

By Elizabeth Howell July 09, 2020

Rocky planets that formed early in our Milky Way galaxy's 13.2-billion-year history have a better chance of supporting life than worlds that were later to the party, a new study suggests.

Exposed planetary core spotted circling distant star

By Mike Wall July 01, 2020

6 exomoons orbiting alien worlds? Well, it's complicated.

By Meghan Bartels June 26, 2020

In our neighborhood, three quarters of planets have at least one moon, but no such object has been confidently discovered so far in distant star systems — such worlds are just too small and far away.

Newfound 'super-Earth' exoplanets bear clues about atmospheres of alien worlds

By Charles Q. Choi June 25, 2020

The brightest red dwarf star in the sky may be the best chance astronomers have yet to analyze the atmospheres of alien worlds — and perhaps detect whether those worlds have life, a new study finds.

Newly discovered alien planet spotted zipping around highly active star

By Elizabeth Howell June 25, 2020

Two veteran NASA planet-hunting missions found a Neptune-size planet that circles its young star every Earth week.

Dusty alien planets could be more likely to harbor life, study suggests

By Chelsea Gohd June 12, 2020

Dusty alien planets might have a better chance at harboring life, a new study suggests.

Record breaker! Briefcase-size satellite spots alien planet

By Mike Wall June 05, 2020
