  • Further Work on TRAPPIST-1
    A closely packed planetary system like the one we?ve found at TRAPPIST-1 offers intriguing SETI possibilities. Here a SETI search for directed radio transmissions aimed at the Earth gives way to an attempt to overhear ongoing activity within another stellar system. For it?s hard to conceive of any civilization developing technological skills that would turn […]

  • Breakthrough Listen Data Becoming Available
    Andrew Siemion (Berkeley SETI Research Center) presented results from the first year of the Breakthrough Listen initiative last Thursday at the Breakthrough Discuss meetings in Palo Alto. The data can be acquired here, with the caveat that file sizes can be gigantic and the data formats demand specialized software. Background information and details are available […]

  • On Breakthrough Discuss
    Although I hadn?t thought I would get a post off today, I do want to get this Breakthrough Initiatives news release out about the upcoming Breakthrough Discuss meeting. Pay particular attention to the online options for participating. BREAKTHROUGH INITIATIVES TO HOST WORLD-RENOWNED SCIENTISTS AND SCHOLARS IN SUMMIT ON LIFE IN THE UNIVERSE AND SPACE EXPLORATION […]

  • Mission Concepts: Bound Orbits around Other Stars
    Can we use a laser array to get a fast probe to another star? Breakthrough Starshot relies upon the notion, which was first advanced by Robert Forward all the way back in 1962, and subsequently considered by George Marx in 1966, along with hosts of researchers since. With beamed energy we leave the propellant behind, […]

  • Proxima Mission: Fine-Tuning the Photogravitational Assist
    Deceleration has always been problematic in projected schemes for interstellar travel. A flyby of a star at a substantial percentage of lightspeed yields a fraction of the data that would be obtainable by a probe slowed into orbit in the target system. But how to slow down? In particular, how do you slow down when […]
