Interstellar 'Tsunami Waves' Sweep Past Voyager 1


Source - NASA Science News for Dec. 16, 2014

Since 2012, NASA's Voyager 1 spacecraft has experienced three 'tsunami waves' in interstellar space. The most recent, which reached the spacecraft earlier this year, is still propagating outward according to new data.

The Sounds of Interstellar Space


Source - NASA Science News for Nov. 1, 2013

As Voyager 1 recedes from the solar system, researchers are hoping the spacecraft will beam back tones from plasma waves, a form of "interstellar music" that reveals conditions in the realm of the stars.

Voyager Captures Sounds of Interstellar Space


Source - NASA Jet Propulsion Laboratory: Sep 6, 2013

NASA's Voyager 1 spacecraft captured these sounds of interstellar space. Voyager 1's plasma wave instrument detected the vibrations of dense interstellar plasma, or ionized gas, from October to November 2012 and April to May 2013.

The graphic shows the frequency of the waves, which indicate the density of the plasma. Colors indicate the intensity of the waves, or how "loud" they are. Red indicates the loudest waves and blue indicates the weakest.

The soundtrack reproduces the amplitude and frequency of the plasma waves as "heard" by Voyager 1. The waves detected by the instrument antennas can be simply amplified and played through a speaker. These frequencies are within the range heard by human ears.

Scientists noticed that each occurrence involved a rising tone. The dashed line indicates that the rising tones follow the same slope. This means a continuously increasing density.

When scientists extrapolated this line even further back in time (not shown), they deduced that Voyager 1 first encountered interstellar plasma in August 2012.

The Voyager spacecraft were built and continue to be operated by NASA's Jet Propulsion Laboratory, in Pasadena, Calif. Caltech manages JPL for NASA. The Voyager missions are a part of NASA's Heliophysics System Observatory, sponsored by the Heliophysics Division of the Science Mission Directorate at NASA Headquarters in Washington.

Voyager 1 Has Left the Solar System


Source - NASA Science News for Sept. 12, 2013

In an unexpected turn of events, researchers have realized that Voyager 1 left the solar system about a year ago. This event sets in motion a new era of exploration of the realm between the stars.

Voyager 1 Approaches Interstellar Space


Source - NASA Science News for June 27, 2013

Three papers published in today's issue of Science suggest that Voyager 1, now more than 18 billion kilometers from the sun, is closer to becoming the first human-made object to reach interstellar space.

Voyager 1 Tastes Interstellar Space


Source - NASA Science News for Dec. 4, 2012

Eleven billion miles from Earth, NASA's Voyager 1 spacecraft has entered a "magnetic highway" that connects our solar system to interstellar space. This could be one of Voyager 1's last steps on its long journey to the stars.
