NASA’s Voyager 1 spacecraft senses Tsunami Waves from our Sun in Interstellar Space

 

Written by Whitney Clavin

NASA - National Aeronautics and Space AdministrationPasadena, CA – NASA’s Voyager 1 spacecraft has experienced a new “tsunami wave” from the sun as it sails through interstellar space. Such waves are what led scientists to the conclusion, in the fall of 2013, that Voyager had indeed left our sun’s bubble, entering a new frontier.

“Normally, interstellar space is like a quiet lake,” said Ed Stone of the California Institute of Technology in Pasadena, California, the mission’s project scientist since 1972. “But when our sun has a burst, it sends a shock wave outward that reaches Voyager about a year later. The wave causes the plasma surrounding the spacecraft to sing.”

NASA’s Voyager 1 spacecraft sends the Sounds of Interstellar Space

 

Written by Tony Phillips
Science at NASA

NASA - National Aeronautics and Space AdministrationWashington, D.C. – Scifi movies are sometimes criticized when explosions in the void make noise. As the old saying goes, “in space, no one can hear you scream.” Without air there is no sound.

But if that’s true, what was space physicist Don Gurnett talking about when he stated at a NASA press conference in September 2013 that he had heard “the sounds of interstellar space?”

It turns out that space can make music … if you know how to listen.

NASA’s Voyager 1 Spacecraft has entered Interstellar Space

 

NASA - National Aeronautics and Space AdministrationWashington, D.C. – NASA’s Voyager 1 spacecraft officially is the first human-made object to venture into interstellar space. The 36-year-old probe is about 12 billion miles (19 billion kilometers) from our sun.

New and unexpected data indicate Voyager 1 has been traveling for about one year through plasma, or ionized gas, present in the space between stars. Voyager is in a transitional region immediately outside the solar bubble, where some effects from our sun are still evident.

A report on the analysis of this new data, an effort led by Don Gurnett and the plasma wave science team at the University of Iowa, Iowa City, is published in Thursday’s edition of the journal Science.

NASA’s Cassini Spacecraft discovers Plasma changes at Saturn

 

Written by Jia-Rui Cook
NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, CA – Researchers working with data from NASA’s Cassini spacecraft have discovered one way the bubble of charged particles around Saturn — known as the magnetosphere — changes with the planet’s seasons.

The finding provides an important clue for solving a riddle about the planet’s naturally occurring radio signal. The results might also help scientists better understand variations in Earth’s magnetosphere and Van Allen radiation belts, which affect a variety of activities at Earth, ranging from space flight safety to satellite and cell phone communications.
