Announcement of LIGO press conference Feb 11 @ 10:30am EST
Gravitational Waves Detected
100 Years After Einstein's Prediction.
On September 14, 2015 at 09:50:45 UTC the two detectors of the Laser Interferometer Gravitational-Wave Observatory simultaneously observed a transient gravitational-wave signal. The signal sweeps upwards in frequency from 35 to 250 Hz with a peak gravitational-wave strain of 1.0×10^(−21). It matches the waveform predicted by general relativity for the inspiral and merger of a pair of black holes and the ringdown of the resulting single black hole. The signal was observed with a matched-filter signal-to-noise ratio of 24 and a false alarm rate estimated to be less than 1 event per 203 000 years, equivalent to a significance greater than 5.1σ. The source lies at a luminosity distance of 410[+160−180] Mpc corresponding to a redshift z=0.09[+0.03−0.04]. In the source frame, the initial black hole masses are 36[+5−4]M⊙ and 29[+4−4]M⊙, and the final black hole mass is 62[+4−4]M⊙, with 3.0[+0.5−0.5]M⊙c^2 radiated in gravitational waves. All uncertainties define 90% credible intervals. These observations demonstrate the existence of binary stellar-mass black hole systems. This is the first direct detection of gravitational waves and the first observation of a binary black hole merger.

Mastering the game of Go without human knowledge
10.1038/nature24270
https://deepmind.com/blog/alphago-zero-learning-scratch/
Deep Mind has just announced AlphaGo Zero, an evolution of AlphaGo, the first computer program to defeat a world champion at the ancient Chinese game of Go. Zero is even more powerful and is now arguably the strongest Go player in history, according to the company.
While previous versions of AlphaGo initially trained on thousands of human amateur and professional games to learn how to play Go, AlphaGo Zero skips this step. It learns to play from scratch, simply by playing games against itself, starting from completely random play.
It surpassed Alpha Lee in 3 days, then surpassed human level of play, defeating the previously published champion-defeating version of AlphaGo by 100 games to 0 in just 40 days.
The achievement is described in the journal Nature today (Oct. 18, 2017)

AlphaGo Zero trains itself to be most powerful Go player in the world

Feb 2018 / Space-X
Thu Feb 08, 2018 3:14 am
Space-X : On Tuesday, Feb. 6th at 3:45 PM ET , Falcon Heavy successfully lifted off from Launch Complex 39A
at Kennedy Space Center in Florida. Falcon Heavy is the most powerful operational rocket in the world by a factor
of two , with the ability to lift into orbit nearly 64 metric tons (141,000 lb) -- a mass greater than a 737 jetliner loaded
with passengers , crew , luggage and fuel. Falcon Heavy's first stage is composed of three Falcon 9 nine - engine cores
whose 27 Merlin engines together generate more than 5 million pounds of thrust at liftoff,equal to approximately eighteen
747 aircraft. Only the Saturn V moon rocket, last flown in 1973, delivered more payload to orbit.[ In the process, Elon Musk
launched a Tesla Roadster into space on a one-way mission to Mars and successfully landed 2 of 3 Falcon 9 rockets used for the
launch .]

April 2018 Transiting Exoplanet Survey Satellite
Sun Apr 22, 2018 3:00 am
Big Picture
A Falcon 9 rocket lifts off at 6:51 p.m. EDT from Space Launch Complex 40 at Cape Canaveral
Air Force Station carrying NASA's Transiting Exoplanet Survey Satellite, or TESS. It is the next
step in the search for planets outside of the solar system and orbiting other nearby, bright stars.
The mission is designed to find these planets, also known as "exoplanets," orbiting other nearby,
bright stars periodically blocking their light while the planets transition across the astronomical object.
