We now know there are more planets than stars in the galaxy. Many of them are very different from ours. How would we know if any of them had life? Shawn Domagal-Goldman, astrobiologist at NASA’s Goddard Space Flight Center, discusses...

In part 2, Dr. Garvin continues explaining how much left we have to learn about Venus and recounts NASA's visits to the moon with the Apollo program.

Astronomers using the Hubble Space Telescope have conducted the first spectroscopic survey of Earth-sized planets in the TRAPPIST-1 system's habitable zone. Hubble reveals that at least the inner five planets do not seem to...

On July 4, NASA’s Transiting Exoplanet Survey Satellite (TESS) completed its primary mission, a two-year-long survey that imaged about 75% of the starry sky. In capturing this giant mosaic, TESS has found 66...

In a generic brick building on the northwestern edge of NASA’s Goddard Space Flight Center campus in Greenbelt, Maryland, thousands of computers packed in racks the size of vending machines hum in a deafening...

On April 23, NASA's Swift satellite detected the strongest, hottest, and longest-lasting sequence of stellar flares ever seen from a nearby red dwarf star. The initial blast from this record-setting series of explosions...

What planets could have had life on them in our solar system? What planet or moon might have life besides Earth?<br/>
Searching for Life in the Galaxy, Part 2

Just as our own sun has many planets, other stars also have planets of their own. These are called exoplanets. The first of these was discovered in the 1990s, and since then, thousands of others have been found, thanks largely to the...

How many movies have you seen about aliens? Are any of them realistic? Does intelligent life exist elsewhere in the universe or are we totally alone? Both options are rather terrifying, frankly. But there are scientists that spend their...

We've briefly discussed exoplanets and some methods that we can use to detect them, but we haven't yet looked at any specific ones. You may have heard of the TRAPPIST-1 system that was discovered recently, and for good reason, it's a...

It's the first time scientists have found water in the atmosphere of a planet that also orbits in its star's habitable zone.
