It’s official: Voyager 1 has slipped from the solar system.
Launched in 1977, Voyager 1 traveled past Jupiter and Saturn and is now more than 11.66 billion miles (18.67 billion kilometers) from the sun, becoming the first spacecraft to enter interstellar space. Proof of this long-anticipated milestone for the storied spacecraft comes in a study released Thursday by the journal Science and announced at a celebratory NASA headquarters briefing.

Pale Blue Dot: Distant Spacecraft Photograph Earth (Cassini spacecraft)



 Click to Enlarge

July 23, 2013:  Color and black-and-white images of Earth taken by two NASA interplanetary spacecraft on July 19 show our planet and its moon as bright beacons from millions of miles away in space.

NASA's Cassini spacecraft captured the color images of Earth and the moon from its perch in the Saturn system nearly 900 million miles (1.5 billion kilometers) away. MESSENGER, the first probe to orbit Mercury, took a black-and-white image from a distance of 61 million miles (98 million kilometers) as part of a campaign to search for natural satellites of the planet.

Keep out the light, the cold and mozzies!

Found this in the latest S&T.

It will keep out stray light, mozzies and other unwanted flying crawlies. (After the flying  part - they crawl).

 The Delux model is fitted with a stereo MP3 player. ;-)

This is DIY 101 for astro geeks.

Fracking Scary!

"ASH members are concerned that light pollution is starting to creep in at this site, which is also home to the Black Forest Star Party in September. The light pollution comes from nearby drilling rigs for natural gas in the Marcellus Shale. Fortunately, the sky was very dark on Saturday night. Cherry Springs State Park operations manager Chip Harrison gave a talk about how the fracking companies frequently cut back on fl aring activity during star parties. He pointed out that these companies receive a lot of negative publicity, so they’re usually happy to generate goodwill by cooperating with star party organizers. The key is to understand their concerns, make reasonable requests, and communicate clearly the desired actions and the reasons for them."

NASA - Image of the Day Gallery

Targeting Earth Photographs From Orbit

Inside the Cupola, NASA astronaut Chris Cassidy, an Expedition 36 flight engineer, uses a 400mm lens on a digital still camera to photograph a target of opportunity on Earth some 250 miles below him and the International Space Station. Cassidy has been aboard the orbital outpost since late March and will continue his stay into September.
