Chemical sleuthing unravels possible path to forming life’s building blocks in space

400 Bad request

​Scientists have used lab experiments to retrace the chemical steps leading to the creation of complex hydrocarbons in space, showing pathways to forming 2-D carbon-based nanostructures in a mix of heated gases.

The latest study, which featured experiments at the Department of Energy’s Lawrence Berkeley National Laboratory (Berkeley Lab), could help explain the presence of pyrene, which is a chemical compound known as a polycyclic aromatic hydrocarbon, and similar compounds in some meteorites.

Freon find deals blow to ET search | Cosmos

This is a bit of a bummer. Astronomers had thought the presence of freon might be an indicator of biological life. However, turns out it’s far more common than previously thought.

Discovery alert! A nearby super Earth

Cool! A nearby “Super Earth” –   only 21 light-years away in the inner habitable zone of its small, red ‘M dwarf’ star. Almost 3 times more massive than Earth, this exoplanet is 21 light-years away. It takes only two weeks to orbit its star, closer than Mercury is to the Sun. But since M dwarf stars are cool compared to our Sun, the planet still has the potential for water.

A SETI Signal?

A possible SETI signal?

A star system 94 light-years away is in the spotlight as a possible candidate for intelligent inhabitants, thanks to the discovery of a radio signal by a group of Russian astronomers.

A SETI Signal? | SETI Institute

HD 164595, a solar system a few billion years older than the Sun but centered on a star of comparable size and brightness, is the purported source of a signal found with the RATAN-600 radio telescope in Zelenchukskaya, at the northern foot of the Caucasus Mountains.  This system is known to have one planet, a Neptune-sized world in a very tight orbit, making it unattractive for life.  However, there could be other planets in this system that are still undiscovered. 

The signal seems to have been discussed in a presentation given by several Russian astronomers as well as Italian researcher, Claudio Maccone, the Chair of the International Academy of Astronautics Permanent SETI Committee.  Maccone has recently sent an email to SETI scientists in which he describes this presentation, including the signal ascribed to star system HD 164595.
