New data from the Juno spacecraft gives more evidence that sprites arcing hundreds of miles occur in the atmosphere of Jupiter. These transient luminous events, or TLEs, were captured with UV sensors.
Scientists predicted these bright, superfast flashes of light should also be present in Jupiter’s immense roiling atmosphere, but their existence remained theoretical. Then, in the summer of 2019, researchers working with data from Juno’s ultraviolet spectrograph instrument (UVS) discovered something unexpected: a bright, narrow streak of ultraviolet emission that disappeared in a flash.
On Earth, sprites and elves appear reddish in color due to their interaction with nitrogen in the upper atmosphere. But on Jupiter, the upper atmosphere mostly consists of hydrogen, so they would likely appear either blue or pink.
Earlier this year, NASA released other illustrations of TLEs and “mushballs” likely present in Jupiter’s atmosphere.
One of the most popular questions asked of astronauts is how they use the bathroom in space. That prompted NASA astronaut Chris Cassidy—who just retuned to Earth last week after six months as commander of the International Space Station—to create a video guide to using the, er, Waste and Hygiene Compartment (WHC) as it’s officially… READ THE REST
NASA’s asteroid sampler spacecraft Osiris-Rex managed to stuff itself so full of so much asteroid dust during this week’s grab-and-dash maneuver, it’s now jammed open, and precious asteroid dust particles are just drifting off into space, said NASA scientists on Friday. The news comes just three days after the Osiris-Rex spacecraft briefly touched — booped,… READ THE REST
China’s Tianwen 1 space probe on its way to Mars ejected a small camera to grab selfies of the spacecraft. See below. The video above, captured by the probe, shows the camera tumbling off into the void. Tianwen 1 launched in July and will enter Mars orbit in February, assuming all goes as planned. From… READ THE REST
Everybody’s running so fast these days that a laptop or a tablet are the only ways to get a lot done and still keep up your crazy pace. But let’s face it — when you really need to lock in, focus and throw some serious computing power at a project, there’s no substitute for a… READ THE REST
We’re all confronted with hyperbole and grand exaggerated statements every day. However, it’s without a hint of embellishment to say that cybersecurity has never been more important — and could shape the direction of world events. Just days ago, cybersecurity experts identified a hacker selling personal information about nearly 186 million American voters. That information… READ THE REST
When you hear the word apron, you likely think of something like a dainty covering 50s moms would hear while they were cooking. But aprons aren’t just shielding you from a little excess ingredient or some squirting cooking juice. Hands-on professionals from artists and barbers to grillmasters and blacksmiths depend on an apron to both… READ THE REST
