ITHACA, N.Y. - Voyager 1 - one of two sibling NASA spacecraft launched 44 years ago and now the most distant human-made object in space - still works and zooms toward infinity.
The craft has long since zipped past the edge of the solar system through the heliopause - the solar system s border with interstellar space - into the interstellar medium. Now, its instruments have detected the constant drone of interstellar gas (plasma waves), according to Cornell University-led research published in
Nature Astronomy.
Examining data slowly sent back from more than 14 billion miles away, Stella Koch Ocker, a Cornell doctoral student in astronomy, has uncovered the emission. It s very faint and monotone, because it is in a narrow frequency bandwidth, Ocker said. We re detecting the faint, persistent hum of interstellar gas.

In emptiness of space, Voyager 1 detects plasma ‘hum’
Voyager 1 – one of two sibling NASA spacecraft launched 44 years ago and now the most distant human-made object in space – still works and zooms toward infinity.
As the craft toils, it has long since zipped past the edge of the solar system through the heliopause – the solar system’s border with interstellar space – into the interstellar medium. Now, its instruments have detected the constant drone of interstellar gas (plasma waves), according to Cornell-led research published May 10 in Nature Astronomy.
Examining data slowly sent back from more than 14 billion miles away, Stella Koch Ocker, a Cornell doctoral student in astronomy, has uncovered the emission. “It’s very faint and monotone, because it is in a narrow frequency bandwidth,” Ocker said. “We’re detecting the faint, persistent hum of interstellar gas.”

“Why have there been no ‘great’ women composers?” asked accordionist and experimental musician Pauline Oliveros in a 1970 New York Times essay. Why indeed, wonders Sisters With Transistors.
Many people may be familiar with Delia Derbyshire, the electronic music pioneer who composed the theme of Doctor Who in 1963 as part of her duties with the BBC Radiophonic Workshop. But how much do you know about Clara Rockmore, the Lithuanian virtuoso who became the first theremin star and who assisted its
