The voyage continues…


Space­craft Voy­ager 1 has officially entered inter­stel­lar space, although exact­ly when it left the helios­phere is still up for debate.m“This is the first man­made object that has left our home—our bub­ble—ever,” says Merav Opher, as­so­ciate pro­fes­sor of astron­o­my at Boston Uni­ver­si­ty and a guest inves­ti­ga­tor on NASA’s Voy­ager team. “Voy­ager is like our scout, telling us what lies beyond our home.”

NASA’s recent announce­ment, based on a new study pub­lished in the jour­nal Sci­ence, fol­lows a debate among some astronomers as to when or even whether the tran­sit beyond the heliopause had occurred. The Sci­ence study places the tran­sit as com­plet­ed on August 25, 2012.

One AU is the dis­tance from the sun to the Earth, which is about 93 mil­lion miles or 150 mil­lion kilo­me­ters. Nep­tune, the most dis­tant plan­et from the sun, is about 30 AU. NASA’s Voy­ager 1, humankind’s most dis­tant space­craft, is around 125 AU. It will take about 300 years for Voy­ager 1 to reach the inner edge of the Oort Cloud and pos­si­bly about 30,000 years to fly beyond it.

One of features of voyager is this golden disk, with a map of how to get to earth, pictures of mankind, and sounds of humanity. Sort of like throwing a note in a bottle out to sea- I wonder if anyone will ever read it, and if we’ll still be around.

  1. i think it’s so cool how in like 300 years if there is still humankind they will be able to learn more about the Oort Cloud and they will know so much more about space then we do. They may even find other living “aliens” out there.


  2. I think it’s so interesting that it might take 30,000 years for the voyager to pass the Oort Cloud! It just goes to show how incredibly huge outer space really is! Also I love how they added the map and picture of the earth to the disk. It sorta gives me a sense of wonder of anything will read it!
