The astro-comb will try to 'rediscover' Venus by measuring its gravitational effects on th...

Astronomers looking for exoplanets are using a fine-toothed comb – a fine-toothed astro-comb, to be precise. And just to make sure it works, the first planet they’ll be looking for is Venus. Developed by astronomers Chih-Hao Li and David Phillips of the Harvard-Smithsonian Center for Astrophysics, the astro-comb uses a new spectroscopic device installed in the Italian Telescopio Nazionale Galileo in the Canary Islands that will detect the beclouded planet by its gravitational effect on the Sun as a test of a potentially valuable tool in the hunt for Earth-like planets beyond our Solar System.  Read More

With the aid of NASA's Kepler spacecraft, a team of astronomers, including members from the Harvard-Smithsonian Center for Astrophysics, has discovered an exoplanet with the longest yearly cycle ever recorded. The planet, imaginatively named Kepler-421b, takes an impressive 704 days to orbit its parent, a dim type K star.  Read More

The Pistola con Caricato is a three-barreled revolver with 18 chambers in 6.35 x 16 mm sem...

A host of unusual firearms have been floated and (mostly) abandoned over the two centuries of largely trial-and-error design. After our recent coverage of Arsenal Firearm's AF2011-a1 double barrel semiautomatic pistol, we wondered if more extreme versions of multi-barrel repeating handguns existed. The outlandish Pistola con Caricato three-barreled revolver is a definite candidate.  Read More

What do you do when you're the world's largest museum but can display only 2 percent of the 137 million items in your collection (a mere 2.75 million) at any given time? In an effort to get more of their treasures into the public eye, specialists at the Smithsonian Institution's nineteen collective museums and galleries hit upon the solution of digitizing their collection and 3D printing key models and displays suitable for traveling exhibitions. It's a tall order, but one that's sure to give the rapidly blooming business of additive manufacturing a huge boost.  Read More
