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.

Although it’s uncertain when the Five-hundred-meter Aperture Spherical radio Telescope (FAST) will zoom-in on Tabby’s star, hopes are high that the world’s biggest single dish radio observatory will contribute greatly to Breakthrough Listen’s SETI project.

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.

The latest venture by Russian billionaire Yuri Milner in his quest to find alien life is set to be unveiled by Stephen Hawking on Tuesday.
Starshot is the latest project in Milner’s decade-long search for extraterrestrial intelligence (SETI), which he set up in July 2015, under the banner Breakthrough Initiatives. Continue reading Stephen Hawking and Billionaire to Hunt Aliens
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. Continue reading Seeking the Aliens Who Are Looking Right At Us
Planetary formation remains one of the biggest puzzles in modern astronomy. Although we know that the vast majority of stars possess systems of planets — from tiny Mercury-sized rocky worlds to massive gas giants that would dwarf Jupiter — mysteries remain as to how material accretes to form small planetoids and how long it takes for these planetary embryos to plump-up into what we would consider to be planets. Continue reading ALMA Spies Baby Stars’ Planetary Workshops
Old, dense and isolated clusters of stars might be the perfect place to find intelligent life beyond Earth, say scientists who presented a study about how so-called “globular clusters” may be a cradle of life for advanced civilizations.
“If they house planets, globular clusters provide ideal environments for advanced civilizations that can survive over long times,” astronomer Rosanne Di Stefano, with the Harvard-Smithsonian Center for Astrophysics, said in a summary of a paper to be presented at the American Astronomical Society meeting in Kissimmee, Fla., this week.

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?
