Icy particles along Saturn’s B ring rise dramatically in mile-high spikes, seen by Cassini in August 2009. (NASA/JPL-Caltech/SSI) A field of spike-like structures rise up over two miles from the outer edge of Saturn’s B ring in the amazing image above, captured by Cassini during Saturn’s spring equinox in August 2009. These pointy perturbations are caused by…

NOAA and NASA Open a New Set of Eyes on the Sun
Look out SDO—there’s another set of eyes watching the Sun in a wide swath of wavelengths! The images above are the first from the Solar Ultraviolet Imager (SUVI) instrument aboard NOAA’s new GOES-16 satellite, positioned in a geostationary orbit about 22,200 miles from Earth. These are SUVI’s first successful test images, captured on Jan. 29, 2017; once fully…
Seven Earth-sized Exoplanets Discovered Around a Single Nearby Star!
In what’s being called a “record-breaking exoplanet discovery” NASA announced today the detection of not one, not two, not three or four but seven exoplanets orbiting the ultra-cool dwarf star TRAPPIST-1, located just under 40 light-years away in the constellation Aquarius. (That’s astronomically very close, although still 235 trillion miles distant.) What’s more, these exoplanets aren’t bloated hot…
OSIRIS-REx Captures a Picture of Jupiter from L4
NASA’s OSIRIS-REx may be designed to study asteroids close up but recently it’s captured a view of something farther away and much, much larger: the giant planet Jupiter and three of its largest moons at a distance of over 400 million miles! The image was taken on Feb. 12, 2017, when the spacecraft was 76 million…
Can Pluto Be a Planet Again Already?
Ever since the discovery of Pluto by Clyde Tombaugh in 1930 our Solar System was known to have nine planets orbiting the Sun. “My Very Eager Mother Just Served Us Nine Pizzas” was a popular mnemonic in my elementary school days to help remember the order of major planets from Mercury outward. But in 2006,…
Meteors May Make Your Hair Hiss
Have you ever gone outside on a cold, clear night to watch a meteor shower and witness a super-bright fireball racing across the sky so brilliantly that you could swear you could hear it? Turns out the sizzling noise might not have been all in your head after all…but rather on it. (And here’s science to prove it.)
Juno Will Not Enter Tighter Orbits Around Jupiter, Team Decides
NASA’s Juno spacecraft will remain in 53-day-long orbits of Jupiter rather than rocket down to smaller 14-day orbits, despite the mission’s original plan to do so. Announced today, Feb. 17, this decision comes after evaluation of issues with helium valves that prevented orbital reduction burns in October and December of 2016. “During a thorough review, we looked at multiple scenarios that…
There’s a Cerulean Storm Swirling on Saturn’s North Pole
Like some giant beast’s great blue eye Saturn’s north polar vortex appears to glare up at Cassini’s wide-angle camera in this image, a color-composite made from raw images acquired in red, green, and blue visible light wavelengths on February 13, 2017.
Here’s Why We Will Definitely Attempt a Landing on Europa
Both the book and the movie 2010 told us we can pretty much go wherever we want in the Solar System except Europa; “ATTEMPT NO LANDING THERE.” But Europa is exactly where we should go, especially if we want to take advantage of the best chances we know of to find extraterrestrial life. This ice-covered cue…
Chelyabinsk: a Blast From the Not-Too-Distant Past (or, How’s That Space Program Coming Along?)
Four years ago today an explosion shattered the morning sky over the Chelyabinsk region in southwestern Russia, the result of a 60-foot-wide fragment of an asteroid entering Earth’s atmosphere at over 40,000 mph and brilliantly blowing itself to smithereens at 97,000 feet up. Even at that altitude, the resulting flash of light and air blast was powerful…
Voyager 1’s Famous Long-Distance Valentine
If you’re in love with space then you’ll fall head over heels for this: it’s a picture of Earth taken from the Voyager 1 spacecraft after it passed the orbit of Pluto back in 1990—on Valentine’s Day, no less. That image of our planet from almost 4 billion miles away inspired Carl Sagan to write his famous…
The Chirp Heard Round the World: How Scientists Confirmed the LIGO Detection
It’s been a year since researchers with the Laser Interferometer Gravitational-wave Observatory (LIGO) announced the first direct observations of gravitational waves, the oscillations in the fabric of space and time created by powerful cosmic events—like the merging of two massive black holes. This cosmic phenomenon was first predicted by Einstein in 1915, but it took a century…
