So apparently Voyager 1 left our solar system on July 27, 2012

A re-interpretation of Voyager 1 data is refuelling the debate over whether the spacecraft has truly left the cozy confines of our solar system. According to a new University of Maryland study, it exited the heliosphere last year. The confusion, say the researchers, stems from NASA's failure to account for a… » 8/16/13 4:30pm 8/16/13 4:30pm

Our solar system has a tail and it's shaped like a four-leaf clover

According to NASA, both the existence of our solar system's tail and its general shape have now been confirmed, which... wait – our solar system has a tail? » 7/12/13 8:37am 7/12/13 8:37am

New Insights Emerge About Voyager 1's Epic Journey to the Edge

The Voyager 1 spacecraft has entered into a turbulent and dynamic region of space that's once again resetting our notions of what's out there at the edge of the solar system. » 6/28/13 7:30am 6/28/13 7:30am

NASA's Voyager 1 spacecraft enters an unexplored region of space: The…

NASA's Voyager 1 is the most far-flung object ever launched, having spent the last 35 years putting upwards of 11-billion miles between itself and the Sun, soaring through space at speeds approaching 11 miles per second. Now, the Agency reports that Voyager has entered an entirely new region of space at the fringes of… » 12/04/12 8:20am 12/04/12 8:20am

How soon will Voyager 1 leave the solar system?

Thirty-five years ago today, NASA launched its Voyager 1 spacecraft on a mission to photograph Jupiter and Saturn at unprecedented levels of detail. On November 16, 1980, the spacecraft captured the photograph of Saturn you see up top. Four days later, its primary mission was over. » 9/05/12 11:00am 9/05/12 11:00am

NASA says the Voyager 1 spacecraft has entered into an unprecedented…

Voyager 1 has been steadily working its way out of the solar system, and it now appears to have entered into a completely new region of space. NASA says it'll only be a matter of time before the spacecraft exits the solar system completely, becoming the first human-made object to enter interstellar space. » 6/15/12 12:20pm 6/15/12 12:20pm

NASA probe reveals the unexpected "atmosphere" that surrounds our…

NASA's Interstellar Boundary Explorer, or IBEX, has spent the last four years exploring the very edge of our solar system, where giant magnetic bubbles repel incoming charged particles while neutral ones stream in on their way to the Sun. » 1/31/12 3:52pm 1/31/12 3:52pm

NASA's Voyager 1 has reached the very fringes of our solar system, and…

When NASA's Voyager 1 spacecraft launched from Cape Canaveral, Florida in 1977, its primary mission was to explore Jupiter and Saturn, the largest planets in our solar system. On November 16, 1980, the spacecraft captured this photograph of Saturn from a distance of just 5.3-million kilometers. » 12/08/11 4:30pm 12/08/11 4:30pm

Why The Sun Is A Delinquent Parent

You already know that the sun can be dangerous because of the harmful effects of UV rays, but were you aware of the problems posed by it failing to protect us from cosmic rays? » 6/29/09 8:30am 6/29/09 8:30am

NASA's IBEX Ready to Measure the Edges of Our Solar System

A NASA mission to measure and study the mysterious edge of the solar system is underway this week. The Interstellar Boundary Explorer (IBEX) is one of the low-cost "Small Explorers" missions - it can study the termination shock area of our solar system without even leaving Earth's orbit. How will it manage that? By… » 10/20/08 10:40am 10/20/08 10:40am

Does the New Shape of the Solar System Prove Vernor Vinge is Right…

By now you've probably heard the news about our solar system not quite being the shape that everybody thought. A study in Nature today shows results gathered from the two Voyager space probes launched in the 1970s, which are both nearing the edge of the heliosphere, the region where the solar winds end and deep space… » 7/02/08 3:00pm 7/02/08 3:00pm
