Remember a while back when we wrote about the Search for Extraterrestrial Intelligence's (SETI) Allen Telescope Array (ATA) was shut down due to lack of funding? It seems the government wasn't keen on supporting the search for our interstellar neighbors, so SETI turned to you for help. Guess what guys we did it! The Allen Array is back in business!
Stop me if you've heard this before, but astronomers have used the Kepler planet huntin' space telescope to find the most (potentially) habitable alien planet yet.
Here on Earth, we make it very obvious that a (mostly) intelligent species lives here. We broadcast signals on nearly every wavelength imaginable, and one of those is visible light: every night, we inform the universe of our presence through our rampant light pollution, and extraterrestrials may be doing the same thing.
We're fairly certain that we haven't yet made contact with any extraterrestrial intelligence (ETI), but when we do — and yes, let's go with when — it's definitely going to be big news. What is somewhat less definite is what form that news will take: will it be beneficial to humanity, with ETI offering to solve all of our problems, or will ETI turn out to be hostile and eat our entire species for dinner? A group of scientists from Pennsylvania State University and NASA's Planetary Science division have put a lot of thought into many different scenarios of ETI interactions with humanity, and here are 17 different ways that first contact might (or might not) go.
It's possible for an asteroid impact to send rocks from other planets to Earth, which is how I got myself a Mars rock and why this guy thinks he's found aliens. New simulations show that it's possible for things to work in the other direction as well, sending rocks from Earth out into our solar system and on to interstellar space.
Economist Paul Krugman, who won a Nobel Prize for his work on developing the New Trade Theory, has a fresh one in the works: the U.S. government should fake an alien invasion to stimulate the economy.
Not too long ago it was feared that the SETI project's Allen Telescope Array, which is made up of 42 networked radio telescopes, was destined to switch off forever. While the array is currently down, it's scheduled to be reactivated — and soon.
After one intrepid Google Mars user reported spotting a structure on the surface of Mars, the Internet at large took it way too seriously, as the Internet is wont to do. But someone actually bothered to ask the guy in charge of one of the telescopic cameras currently orbiting Mars what the deal is, and his take probably won't surprise you. Or maybe it will.
French scientists have confirmed with computer models that Gliese 581d, a planet orbiting a red dwarf star about 20 light years from here, has a stable atmosphere, comfortable temperatures, and a surface covered in liquid water. It's the first planet orbiting another star that could definitely support life, and it's basically next door.
Late on Friday, the Journal of Cosmology (a free but peer-reviewed scholarly journal) published a paper on their website by NASA astrobiologist Dr. Richard B. Hoover that showcases a variety of microscopic fossilized structures from inside meteorites that are possibly the remains of extraterrestrial bacteria. Aliens, for real.
