After 35 Years, Voyager Nears Edge Of Solar System

Originally published on Fri March 21, 2014 2:33 pm

In addition to surveying the planets, the Voyager mission also spent time studying the planets' satellites, or moons. This mosaic image, taken in 1989, shows Neptune's largest satellite, Triton. Triton has the coldest surface temperature known anywhere in the solar system.

The Voyager 1 spacecraft's 35th anniversary is proving to be unexpectedly exciting, as scientists gathered this week to examine new hints that the spacecraft is on the verge of leaving our solar system.

Voyager 1 is now more than 11 billion miles away from Earth. It blasted off in September 1977, on a mission to Jupiter and Saturn. But it also carried a Golden Record filled with music and the sounds of our planet, in case it encountered intelligent life as it moved out toward the stars.

The Toothbrush: It's In The Space Station's Toolbox. How About Yours?

The toothbrush/space tool.

When we heard that astronauts aboard the International Space Station took a spare toothbrush along on a spacewalk today and used it to help clean debris from around some bolts they needed to secure in order to install a power unit, it got us thinking.

Just how versatile are old toothbrushs? We know we've used them to:

-- Clean bike gears.

-- Get grime out of our hubcaps.

-- Get at the crust around a car battery's terminals.

-- Polish jewelry.

Using NASA's Infrared Telescope, Scientists Uncover Millions Of Black Holes

With its all-sky infrared survey, NASA's Wide-field Infrared Survey Explorer, or WISE, has identified millions of quasar candidates. This image zooms in on one small region of the WISE sky, covering an area about three times larger than the moon. The WISE quasar candidates are highlighted with yellow circles.

This paragraph from NASA worried us:

"In one study, astronomers used WISE to identify about 2.5 million actively feeding supermassive black holes across the full sky, stretching back to distances more than 10 billion light-years away. About two-thirds of these objects never had been detected before because dust blocks their visible light. WISE easily sees these monsters because their powerful, accreting black holes warm the dust, causing it to glow in infrared light."
