The SETI Institute belives that planetary systems orbiting red dwarfs — dim, long-lived stars that are on average billions of years older than our sun — are worth investigating for signs of advanced extraterrestrial life. The star that’s closest to our sun, Proxima Centauri, is a red dwarf. A variety of observing efforts, including the University of London's Pale Red Dot Initiative, are looking for earthlike habitable planets around Proxima Centauri (shown below).

The origin of many of the most precious elements on the periodic table, such as gold, silver and platinum, has perplexed scientists for more than six decades. Now a recent study has an answer, evocatively conveyed in the faint starlight from a distant dwarf galaxy.

"About 3.4 billion years ago, a big meteorite impact triggered the first tsunami wave. This wave was composed of liquid water. It formed widespread backwash channels to carry the water back to the ocean," said Alberto Fairén, Cornell visiting scientist in astronomy and principal investigator at the Center of Astrobiology, Madrid.

Imagine if we sent up a visible signal that could eventually be seen across the entire universe. Imagine if another civilization did the same. Photonics advances allow us to be seen across the universe, with major implications for the search for extraterrestrial intelligence, says UC Santa Barbara physicist Philip Lubin.

A team of astronomers jointly led by Ivo Seitenzahl from The Australian National University (ANU) detected the faint afterglow of a supernova, and found it was powered by radioactive cobalt-57. The discovery gives important new clues about the causes of Type Ia supernovae, which astronomers use to measure vast distances across the Universe.

Jupiter's 'Hellish' Io --"A Time Portal to Early Earth"

 

 

Cf-1024

Jupiter's Io is the volcanic epi-center of our solar system. But once you absorb the fact that the Jupiter's innermost moon is slathered in sulfurous lava erupted from 400 active volcanoes, you might turn your attention to scattered bumps and lumps that turn out, on closer inspection, to be Io's version of mountains.There are about 100 of them, and they don't look anything like the low lying volcanoes.

"We're studying an alien ocean using methods developed to understand the movement of energy and nutrients in Earth's own systems," says Steve Vance, a planetary scientist at JPL and lead author of an important JPL new study. "The cycling of oxygen and hydrogen in Europa's ocean will be a major driver for Europa's ocean chemistry and any life there, just it is on Earth." Ultimately, Vance and colleagues want to also understand the cycling of life's other major elements in the ocean: carbon, nitrogen, phosphorus and sulfur.

"Landing on the surface of Europa would be a key step in the astrobiological investigation of that world," said Chris McKay, a senior editor of the journal Astrobiology, who is based at NASA Ames Research Center, Moffett Field, Calif. "The hope would be that surface materials, possibly near the linear crack features, include biomarkers carried up from the ocean."

“We’re interested in finding out how we can change the way light behaves, and how that could be useful," says Trinity College professor Paul Eastham. "What I think is so exciting about this result is that even this fundamental property of light, that physicists have always thought was fixed, can be changed.”
