Talk about dedication to science! This biologist stuck his arm into an eel tank – 10 times – to get an accurate measure of an eel’s shock. He said it felt “like touching a horse fence.”
A strikingly beautiful view of a delicate bubble of expelled material around the exotic red star U Antliae helps astronomers understand how stars evolve during the later stages of their life-cycles.
Cassini’s legacy will endure. Click for a video about the atmosphere of Saturn’s large moon Titan, which might resemble that of an early Earth.
We’re near solar minimum, but the sun has been active! Click here for a video of solar flares so far in September, 2017 and for news for the sun’s most recent X-flare.
X-ray astronomers explored how quickly young stars settle down after blasting the space around themselves – including any possible planets – with energetic radiation.
This large asteroid swept closest to Earth on September 1. It’s big enough that astronomers are still catching it in small telescopes, as a small, slow-moving “star.”
Hold out your hand for 10 seconds. A dozen electrons and muons just zipped through your palm. These cosmic rays, scientists believe, come from violent explosions in deep space.
There was only one part of Earth where you could catch the International Space Station crossing the sun’s face during the August 21 solar eclipse. These guys saw it, and created this video.
New short video from NASA about the hunt for potentially hazardous asteroids and comets, and ways to defend Earth against them.
Even as the long-lived Cassini spacecraft gears up for its last moments at Saturn, it’s preparing for a final long-distance look at Titan, Saturn’s large moon, on September 11.
Jellyfish float on ocean currents, but they also swim in a couple of different ways. This post has 2 videos showing 2 different jellyfish propulsion mechanisms.
This video shows a timelapse journey through Smoky Mountains National Park during world’s largest gathering of synchronized fireflies. Beautiful!
SG Collins explains why the Apollo moon landings on the moon in the late 1960s and early ’70s couldn’t have been faked.
Researchers identified simple behavioral rules that allow these tiny creatures to collaboratively build elaborate structures – rafts and towers – with no one in charge.
To celebrate the 2-year anniversary of New Horizon’s flyover of the Pluto system, NASA released these 2 cool videos. Sail over the surface of Pluto and its large moon Charon.
This 5-second video shows a reflected image of the sun – a sun glint – as a bright spot crossing Earth from right to left. It also shows a dark spot – the moon’s shadow – moving the opposite way.
Among wild animals, pronking may be a way of avoiding predators. But when you see an animal pronk, you can’t but think it’s leaping for joy.
NASA says to blame the sun for its moratorium on sending commands to Mars from July 22 to August 1.
New video shows 6 hypervelocity stars, zipping from Milky Way center to outskirts. An interaction with our galaxy’s central, supermassive black hole might have kicked them into fast motion.
Low ebb in the 11-year sunspot cycle expected 2019-2020. Want some basic information about the sunspot cycle and its effects? Watch this NASA ScienceCast.
