THIS week’s UFO hearing for US congress revealed that experts think unidentified aerial phenomena are out there and they even have footage.
If alien life does exist, we still don’t know where it comes from but scientists now think they know how many planets could host it.
The SETI (Search for ExtraTerrestrial Intelligence) Project aims to help find alien life and the planets that contain it.
According to Jeff Coughlin, an exoplanet researcher at the SETI Institute and Director of Kepler’s Science Office, there could be about 300 million exoplanets out there that are habitable.
An exoplanet is just a planet that’s outside our solar system and some are much closer than others.
These findings were previously published in The Astronomical Journal.

Coughlin 说 当时: “This is the first time that all of the pieces have been put together to provide a reliable measurement of the number of potentially habitable planets in the galaxy.”
More recently astrobiologist Dirk Schulze-Makuch told Space.com that there could also be “superhabitable planets” out there.
Schulze-Makuch thinks we could be overlooking these planets because they’re different from Earth and we’re mostly looking for planets with signatures similar to our own.
他说 Space.com: “We are so over-focused on finding a mirror image of Earth that we may overlook a planet that is even more well-suited for life.”
Schulze-Makuch and his researchers hope to find superhabitable planets, which are more capable of hosting life than our own.
很遗憾, even finding a habitable planet doesn’t necessarily mean you’ll find life on it.
Schulze-Makuch explained in a recent Space.com article: “We caution that while we search for superhabitable planets, that doesn’t mean that they necessarily contain life.
“A planet can be habitable or superhabitable but uninhabited.”
