1,350 light-years: the distance to a “fiery ribbon” stretching across the Orion Nebula, captured recently by a submillimeter-wavelength camera inside Chile’s Atacama Pathfinder Experiment telescope. The ribbon is actually a glow given off by cold interstellar dust at wavelengths too long for human eyes to see.

2016: the launch year of a NASA spacecraft that will land on the asteroid Bennu, scoop up two ounces of its soil, and then fly the sample back to Earth. Scientists hope the soil will offer clues to the birth of the solar system and life on Earth.

11:18 a.m. ET: the time on May 14, 2013, at which the X-47B autonomous warplane became the first unmanned aircraft to ever complete a catapult launch from the deck of an aircraft carrier (video below)

2.64 billion years: the length of time that water discovered in a Canadian mine may have been untouched by Earth’s atmosphere. The stream may be the oldest free-flowing source of isolated water ever known.

2013: the year scientists created the first cloned human embryo

1,500 watts: the power of the metal-halide vapor lamps in the U.S. Army’s brutal weather simulator, the only lab of its kind to use human test subjects (the lamps are so bright, it’s impossible to look directly at them)

Kepler-76b With Star

An artist’s rendition of the newly discovered planet, Keplar-76b, and the star it orbits. The star has a slight elliptical shape that’s been exaggerated in this illustration.

40 million miles: the distance from Earth to NASA’s exoplanet-hunting Kepler spacecraft, discoverer of distant worlds large and small. The beloved telescope suffered a critical failure this week, though there might still be a way to save it.

Kepler Space Telescope

Kepler is designed to look for Earth-like planets orbiting Sun-like stars in a temperate “Goldilocks zone,” where temperatures are right for liquid water. It stares at a patch of around 156,000 stars in the constellations Cygnus and Lyra and notes teeny blips in their brightness, which could indicate planets passing in front of the stars’ faces.

$300: the price of an animatronic robot kit designed to teach anyone robotics, one of the coolest inventions of the year

$50,000: the price of a sleek, comfortable space suit for space tourists

Fit For Space Teaser

The metal neck ring of the second-generation (2G) space suit proved uncomfortable for a wearer while lying down, so Southern [right] and Moiseev [left] plan to integrate a helmet with a flip-up visor into the 3G suit.

13,000: the number of customers the space tourism industry is expected to have by 2021. Scientists are warning that commercial spaceflights could fill the stratosphere with sunlight-absorbing black carbon.

MARS shot

2.2 millionths of a second: the lifespan of a muon, a negatively charged subatomic particle (scientists need a 600-ton, 50-foot-diameter magnet to measure them)

Moving Muons

A model of the truck that will be used to transport the Muon g-2 ring, placed on a streetscape for scale. The truck will be escorted by police and other vehicles when it moves from Brookhaven National Laboratory in New York to a barge, and then from the barge to Fermi National Accelerator Laboratory in Illinois.
