Trogloraptor spider species discovered and Uranus’ moons’ dance of death
Welcome! "Alien Life" tracks the latest discoveries and thoughts in the various elements of the famous Drake Equation. Here's today's news:
g Stars - Researchers may have discovered a new method to predict solar flares more than a day before they occur. See article.
g Abodes - An intricate dynamical dance performed by the inner moons of Uranus could end in disaster as it appears that certain pairs of moons have the orbital equivalent to two left feet. See article.
g Life - The forests of the coastal regions from California to British Columbia are renowned for their unique and ancient animals and plants, such as coast redwoods, tailed frogs, mountain beavers and the legendary Bigfoot (also known as Sasquatch). Whereas Bigfoot is probably just fiction, a huge, newly discovered spider is very real. Trogloraptor (or "cave robber") is named for its cave home and spectacular, elongate claws. It is a spider so evolutionarily special that it represents not only a new genus and species, but also a new family (Trogloraptoridae). Even for the species-rich insects and arachnids, to discover a new, previously unknown family is an historic moment. See article.

Therefore, it would make sense to go looking at a neighboring "forest," or rather nearby galaxy, for evidence of extraterrestrial intelligence. See article.
g Cosmicus - Fifty years ago, American astronaut John Glenn was launched into Earth orbit. See article.

First exoplanetary system with regularly aligned orbits found and expanding SETI’s search methods
Welcome! "Alien Life" tracks the latest discoveries and thoughts in the various elements of the famous Drake Equation. Here's today's news:
g Abodes - Astronomers have detected the first exoplanetary system with regularly aligned orbits similar to those in our solar system. See article.
g Life - Scientists have built a swimming, tissue-engineered "jellyfish" using silicon and muscle cells. See article.
g Message - The search for extraterrestrial intelligence (SETI) has traditionally hinged on detecting electromagnetic waves, most commonly radio waves but also infrared and x-ray radiation as well as optical pulses at specific frequencies. But in the absence of knowledge about the specific nature of extraterrestrial civilizations, we need to explore all sources of communication possible and not just ones based on electromagnetic waves. Thus the message we would send or receive could and should include everything from symbolic signals to actual physical samples of material signifying the presence of intelligent life. SETI is an endeavor fraught with such momentous potential significance that it would be foolish to hinge it on physics alone. We need to employ other sciences in its service. See article.

Magnetic fields in Moon’s crust and why Native Americans were smart not to go looking for Europeans
Welcome! "Alien Life" tracks the latest discoveries and thoughts in the various elements of the famous Drake Equation. Here's today's news:
g Life - Scientists studying meteorite fragments have found evidence that liquid water inside an asteroid could be the reason that the amino acids found in meteorites show a strong preference for left-handed versus right-handed orientations. See article.
g Cosmicus - Scientists have solved a lunar mystery concerning localized magnetic fields in the Moon's crust. The results could provide safe havens for future space explorers. See article.
g Aftermath - A couple of years ago the eminent theoretical physicist Stephen Hawking warned that a human encounter with intelligent extraterrestrial beings could be dangerous for us, sort of similar to the way Europeans were dangerous to ancient Native Americans, “which didn’t turn out very well for the Native Americans.” In hindsight, it would not have been a good idea for the Native Americans to go searching for Europeans. See article.

Hoax of SETI discovering alien spacecraft and the Pioneer Anomaly
Welcome! "Alien Life" tracks the latest discoveries and thoughts in the various elements of the famous Drake Equation. Here's today's news:
g Abodes - At 10:31 p.m. Pacific time on Aug. 5, NASA's Curiosity rover will begin the first direct search for habitable environments on Mars. See article.
g Message - Has the SETI Institute discovered three objects en route to our world? Alien spacecraft that will arrive in 2012? If you believe a widespread story now being circulated on the internet, and published by the ironically named “Pravda,” you might think so. But it’s all nonsense – it’s a rumor, a hoax, and a fabrication that uncritical web sites have reprinted without checking. See article.
g Cosmicus - The Pioneer 10 and 11 spacecrafts were launched on an outward trajectory from the Sun in 1972 and 1973. In the 1980s, navigators for the mission saw a mysterious deceleration on the two spacecraft. Now, researchers have determined the cause of this “Pioneer Anomaly.” See article.
