Before returning to Earth, NASA astronaut Scott Kelly joked that one of the benefits of spending time in space is that you get taller. So how much taller is he after spending 340 consecutive days aboard the International Space Station? According to NASA’s Jeff Williams, Kelly can (temporarily) gloat that he’s two inches taller than he […]
Now this is great. BB-8, the drone made famous in Star Wars: The Force Awakens recently had a chance to meet a few colleagues that have – and I hate to undermine BB-8 – actually been to space. In cute photo gallery published by NASA and the Jet Propulsion Laboratory (JPL), in addition to a few of […]
This week, NASA’s Mars Reconnaissance Orbiter (MRO) celebrated ten years of orbiting the Martian planet, in which the spacecraft has inspected the planet in unprecedented detail, leading to discoveries such as the possibility of liquid water on present-day Mars. Over the past ten years, NASA’s MRO has identified underground geologic structures, scanned atmospheric layers and […]
Much of the data returned by New Horizons has revealed Pluto to have an incredibly complex geology, with ice mountains and massive canyons. New information, via New Scientist, suggests the planet’s strange atmosphere is just as weird and mysterious. Also, it could have clouds. The report, which includes a few new images, apparently reveals a […]
An amateur astronomer out of Austria has captured astonishing video of what he claims is an asteroid impact on Jupiter.
The event, which occurred on March 17, was initially thought to be a visual anomaly but has since been corroborated by a second video taken in Ireland.
Using a 20-centimeter telescope, the video displays a brief flash on Jupiter’s right-hand side, suggesting it was struck by a comet or asteroid (or alien spaceship?); it’s a faint impact, barely perceptible, but in the second video it’s much easier to see.
According to Phil Plait over at Bad Astronomy, the asteroid was probably only a few hundred feet in diameter though its impact released an incredible amount of energy—about 25 times as high as here on Earth. For context, researchers believe the asteroid that burned up over Russia in 2013 exploded with the energy of 500,000 tons of TNT. Imagine what that would have been like if it were 25 times stronger.
Considering amateur astronomers were able to observe the incident from Earth is also telling of just how immense the impact’s energy was. In simplest terms, Plait said it was a “very, very big bang.”
Check out the videos to see what this “very big bang” looked like.
