New analysis from NASA’s Mars Curiosity rover shows that the red planet is likely flush with organics.
“I am convinced that organics are all over Mars,” said Jennifer Eigenbrode, a biogeochemist and geologist at NASA’s Goddard Space Flight Center in Greenbelt, Maryland.
“They’re all over the surface and they’re probably through the rock record. What that means is something we’ll have to talk about,” Eigenbrode said last week during a National Academy of Sciences workshop about the search for life beyond Earth.

Any intelligent aliens that humans manage to contact probably won’t look much like you or me, or the squid-like creatures in the new film “Arrival.”
If an extraterrestrial species becomes advanced enough to send signals Earthlings can pick up, it will likely shed its traditional biological trappings and become a form of machine intelligence in rather short order, said veteran alien hunter Seth Shostak.
To make his case, Shostak pointed to the path that humanity appears to be on. The human species invented the radio around 1900 and the computer in 1945, and it’s already manufacturing relatively cheap devices with greater computing power than the human brain.

The story behind the famous “Wow!” signal has an eerie quality that has inspired countless science fiction alien encounters and is often lauded as one of the strongest pieces of evidence that we are, in fact, not alone in the universe.
However, its “alien intelligence” authenticity has been questioned since that fabled night on Aug. 15, 1977 at 10:16 p.m. ET when astronomer Jerry Ehman used the Ohio State University’s Big Ear radio telescope to sweep the skies for signals that may have originated from an extraterrestrial civilization.

What if an advanced alien civilization saw our planet across the interstellar expanse and switched on their powerful radio transmitters to send a “hello neighbor!” message… but all of our radio antennae were staring at KIC 8462852 when we really should be paying attention to Omicron Persei.

There’s only one planet in our solar system that can communicate across interplanetary space. But imagine if things were different. Say if Mars, for example, had intelligent beings able to talk to us at the same time as we talked to them — how would that have changed our history?
