WHAT DOES DEEP SPACE SOUND LIKE? 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. Find out what deep space sounds like in a new video from Science@NASA.
PREMATURE SPOOKTACLE: As expected, a coronal mass ejection (CME) hit Earth's magnetic field during the early hours of Oct. 31st, Halloween. The impact, however, was not strong enough to spark a geomagnetic storm or widespread auroras. Instead, unexpectedly, auroras appeared before the impact. Observing from Troms, Norway, Chris and Becki Nation photographed this spooky scene on Oct. 30th:
"AMAZING display last night!" says Chris. "We had a 360 degree light show. It was absolutely breathtaking and we didn't know which way to point the camera."
Becki adds, "we are a family of 6 utter Aurora Addicts: Chris, Becki, Aurora 10, Oceanna 8, Lyrica 3 and Caspian 1. We are currently planning a 4 month road trip in our camper van to Lapland this season from our home in the south of the UK. Things are about to get very green."
But not right away. The geomagnetic field is expected to be mostly quiet for the next 3 days (Nov. 1 - 3). A CME from active sunspot AR1884 could change that forecast, however, so stay tuned. Aurora alerts: text, voice.
