Voyager 1 spacecraft reaches interstellar space, study confirms

University of Iowa space physicist Don Gurnett says there is solid evidence that NASA's Voyager 1 spacecraft has become the first manmade object to reach interstellar space, more than 11 billion miles distant and 36 years ...

The Sun's ripple effect

A new study co-authored by Boston University astronomers indicates that a bow shock (a dynamic boundary between the Sun's heliosphere and the interstellar medium) is highly likely. These findings challenge recent predictions ...

Portrait Earth: Wave at Saturn and Cassini July 19

Smile and say, "Cosmic cheese!" From 898 million miles away, NASA's Cassini-Huygens spacecraft will snap a portrait of Earth July 19 from between Saturn's rings as North America and the Atlantic Ocean repose on the sunny ...

What will Voyager 1 discover at the bow of the solar system?

As the Voyager 1 spacecraft approaches the very edges of our solar system, space scientists await to see if it will discover the solar system's 'bow shock'; a theorized pile up of gas, dust, and cosmic rays, which accumulate ...
