A Big Surprise from the Edge of the Solar System

NASA’s Voyager probes are truly going where no one has gone before. Gliding silently toward the stars, 9 billion miles from Earth, they are beaming back news from the most distant, unexplored reaches of the solar system.

Mission scientists say the probes have just sent back some very big news indeed.

It’s bubbly out there.

According to computer models, the bubbles are large, about 100 million miles wide, so it would take the speedy probes weeks to cross just one of them. Voyager 1 entered the “foam-zone” around 2007, and Voyager 2 followed about a year later. At first researchers didn’t understand what the Voyagers were sensing–but now they have a good idea.

  1. You guys are so totally cool!! We get to see outer space from our computer. May the Congress give you one trillion dollars to continue NASA’s great tradition of space exploration which ultimately gives America the finest innovations know to mankind!! God Bless the Atlantis!! Our last space shuttle. I am very, very sad to see the end of this program!!
