TRAPPIST-1 system with 7 (7?!) exoplanets
- 7 earth-sized terrestrial exoplanets discovered in the TRAPPIST-1 system
- 3 of the planets are within the star’s habitable zone, which means they could harbor liquid water
- The star is an ultra-cool red dwarf, only slightly larger than Jupiter
- It is 40 light-years (12 parsecs) away from Earth in the constellation Aquarius
- The exoplanets were discovered using NASA’s Spitzer space telescope, an infrared telescope in an Earth-trailing heliocentric orbit
- The method is explained pretty well in the video on the site
- It involved measuring the brightness of the star to observe planetary transits
- The James Webb Space Telescope (launching in 2018) will allow direct imaging of the star
- By analyzing the spectrum of light during a transit, the presence of certain gases can be determined (i.e. oxygen, which could indicate life)

AMD reks the CPU market (Ryzen release)
- AMD recently launched the new Ryzen lineup of CPU’s
- Three CPU’s unveiled at their launch event with benchmarks and pricing
- 1New lineup is highly competitive with price to performance
- Three CPU’s
- R7 1800x - $499
