See Ya, Voyager: Probe Has Finally Entered Interstellar Space

This artist's illustration shows the Voyager 1 space probe. The spacecraft was launched on Sept. 5, 1977, and as of August 2012, it is outside the bubble of hot gas, known as the "heliopause," that radiates from the sun.

NASA's two Voyager spacecraft, launched in 1977, have made history in a dramatic fashion by exploring the outer planets: Jupiter, Saturn, Uranus and Neptune. Now one of the vehicles, Voyager I, has made another pioneering leap. It is the first spacecraft to leave the vast bubble of hot gas that surrounds our solar system.

Perhaps one of the most uncomfortable things a doctor has to tell patients is that their medical problems are iatrogenic. What that means is they were caused by a doctor in the course of the treatment.

Sometime these iatrogenic injuries are accidental. But sometimes, because of the limits of medical technology, they can be inevitable. Now, a medical researcher in Seattle thinks he has a way to eliminate some of the inevitable ones.

North Korea appears to be in the process of restarting a nuclear reactor used to produce weapons-grade plutonium, five years after shutting the facility down as part of international disarmament efforts.

New satellite imagery appears to reveal that the 5-megawatt reactor at Yongbyon, which experts believe can produce enough plutonium for one to two bombs a year, shows signs of being operational.

Analysts Nick Hansen and Jeffrey Lewis, writing for the website 38 North, say the satellites show:
