A representative image of Voyager-1 travelling through interstellar space. (Source: Nasa) When Voyager-1 was launched on September 5, 1977, the team that worked on the probe had no idea that even after four decades, the spacecraft would still be sending critical data pings and that too from beyond the Solar System. Now in interstellar space, the area beyond the magnetic bubble inflated by our Sun, Voyager's data is revealing what that new frontier is like. A study published in Nature Astronomy reports what may be the first continuous measurement of the density of material in interstellar spac...

And other stories from the stranger side of life 11 May 2021 Researchers in the Netherlands have trained bees to identify samples infected with Covid. The scientists in the bio-veterinary research laboratory at Wageningen University gave the bees sugary water as a reward after showing them samples infected with Covid and no reward after being shown a non-infected sample. The bees would then spontaneously extend their tongues to receive a reward when presented with an infected sample. Dracula’s castle offers Covid jabs Bran Castle, the inspiration for the vampire’s home in Bram Stoker’s...

"Previously, to measure the density you had to wait for a so-called plasma oscillation event, a finite burst of plasma activity that's triggered by solar activity like coronal mass ejections which send shock waves out into the interstellar medium," she said. "Now, we can measure the plasma density in the absence of these plasma oscillation events, allowing us to trace underlying properties of the plasma and see how the plasma is responding to these shock waves from the Sun. This work gives us the most complete map of the plasma along Voyager 1's trajectory to date." The original plan for the ...

An artist’s impression of the Voyager 1 spacecraft, now 43 years and more than 14 billion miles outbound from Earth. Image: NASA/JPL Until recently, every spacecraft in history had made all of its measurements inside our heliosphere, the magnetic bubble inflated by our Sun. But on Aug. 25, 2012, NASA’s Voyager 1 changed that. As it crossed the heliosphere’s boundary, it became the first human-made object to enter – and measure – interstellar space. Now eight years into its interstellar journey, a close listen of Voyager 1’s data is yielding new insights into what that frontier is ...
