“Is Alpha Centuari’s Proxima b Habitable?” –A Deep Look by Rory Barnes of NASA’s Virtual Planetary Lab

If humanity is to survive beyond the lifetime of our Sun, we must leave our Solar System and travel to the stars. If Proxima b is habitable, then it might be an ideal place to move. Perhaps we have just discovered a future home for humanity! But in order to know for sure, we must make many more observations, run many more computer simulations, and, hopefully, send probes to perform the first direct reconnaissance of an exoplanet. The challenges are huge, but Proxima offers a bounty of possibilities that fills me with wonder. Whether habitable or not, Proxima b offers a new glimpse into how planets and life fit into our universe.

Berkeley SETI Challenges Yesterday’s Reports of a “Strong Extraterrestrial Signal from the Constellation Hercules”

Yesterday, we reported that an international team of astronomers detected signals coming from almost 100 light years away, that appeared to be a strong candidate for extraterrestrial contact, according to a document circulated by Alexander Panov, a theorectical physicist at Lomonosov Moscow State University –“a strong signal in the direction of HD164595, a planet system in the constellation Hercules was detected on May 15, using the RATAN-600 radio telescope (below) in the Russian Republic of Karachay-Cherkessia.”

Groundbreaking Discovery of Proxima Centauri b –“Habitable-Zone Planet Orbiting Our Closest Star Evolved Very Differently Than Earth”

The world’s attention is now on Proxima Centauri b, a possibly Earth-like planet orbiting the closest star, 4.22 light-years away. The planet’s orbit is just right to allow liquid water on its surface, needed for life. But could it in fact be habitable? If life is possible there, the planet evolved very differently than Earth, say researchers at the University of Washington-based Virtual Planetary Laboratory, where astronomers, geophysicists, climatologists, evolutionary biologists and others team to study how distant planets might host life.

Planet Nine –“Could Spell Doom for Our Solar System”

The solar system could be thrown into disaster when the sun dies if the mysterious ‘Planet Nine’ exists, according to research from the University of Warwick. Physicist Dimitri Veras at the University of Warwick has discovered that the presence of Planet Nine could cause the elimination of at least one of the giant planets after the sun dies, hurling them out into interstellar space through a sort of ‘pinball’ effect.

An international team of astronomers has just detected signals coming from almost 100 light years away, and they believe the signal is a strong candidate for extraterrestrial contact, according to a document circulated by Alexander Panov, a theorectical physicist at Lomonosov Moscow State University: “a strong signal in the direction of HD164595, a planet system in the constellation Hercules was detected on May 15, using the RATAN-600 radio telescope (below)  in the Russian Republic of Karachay-Cherkessia.”
