At the beginning of September the world was treated to a fantastic view of the night side of Pluto, captured by the New Horizons spacecraft as it departed the distant icy world on July 14, 2015. Backlit by the sun, Pluto’s surprisingly complex atmospheric haze created a ghostly glow above its crescent-lit limb while frozen mountains cast reflected light upon neighboring Plutonian peaks.
On Thursday, NASA released an update to that image showing a more complete view of Pluto in its backlit glory, created from more high-resolution images that continue to stream in from the Kuiper Belt-bound spacecraft, over three billion miles away.
On Wed. Oct. 28 Cassini performed its lowest-altitude dive yet through the icy plumes of Enceladus, coming just 30 miles from the moon’s surface — that’s only about 6 times higher than a commercial airliner at cruising altitude. But, traveling over 19,000 mph relative to Enceladus (which is 38 times faster than a jet plane!) the pass was over in just a few seconds. Still, Cassini managed to capture some images before, during, and after closest approach — and they’ve arrived on Earth today.
Here are some of the raw images from the E-21 flyby. These have not been validated or made into official releases by NASA or the Cassini imaging team yet, but they are a nice teaser of what we might expect once they are. (And, of course, the science performed during the flyby has yet to be revealed.) So pics only for now!
For decades, far-off Pluto and its moons were just a collection of bright spots in even our most powerful telescopes. Now the dwarf planet and its family of five moons has been revealed in intimate detail with the long-awaited flyby of the New Horizons spacecraft.
Last week the “family portrait” of the Pluto system was made complete when our best close-up arrived of Kerberos, a tiny 7-mile-wide moon that nobody even knew about until 2011. And surprise: it looks like a contact binary!
If you’re as excited about Star Wars: The Force Awakens as I am (and apparently plenty of others — tickets for the film have already sold out two months before it opens) then you’ll love this: a nearly four-minute “supercut” of all of the trailers and teasers that have thus far been released. Assembled by James Darling of Science vs. Cinema, this supercut force-feeds you (see what I did there?) a stunning tsunami of Star Wars awesomeness that, besides being way cool, actually helps to place some of the events in context (even if it’s only implied.)
This is one Star Wars movie that I definitely have a good feeling about!

Yes, it’s true: a rather not-so-tiny near-Earth
asteroid SKULL-SHAPED ZOMBIE COMET (see below) 2015 TB145 will make a relatively close pass by our dear planet Earth on October 31, aka Halloween — the day when certain beliefs profess that the veil separating the worlds of the living and the dead is at its thinnest, allowing spiritual and even physical interaction to occur between both.
Of course there is no scientific evidence that the latter is at all true but it makes for good scary stories around the light of a campfire. And as the first-world campfires of today are the stark lights of computer monitors and smartphone screens, some are trying to weave scary stories about the passing of this asteroid as well. Should you be afraid? Certainly not. (But there is a cautionary tale to be told.)
On Wednesday, Oct. 14 2015, Cassini performed its scheduled “E-20” close pass of Enceladus, a 320-mile-wide moon of Saturn that is now famous for the organics-laden ice geysers that fire from cracks in its southern crust. E-20 is the first of a series of three flybys to be performed before the end of 2015, specifically timed to give the spacecraft a good view of Enceladus’ north polar region now that Saturn is moving into its summer season.
The raw image data from E-20 has just arrived on Earth today (which, by the way, is the 18th anniversary of Cassini’s launch!) and I particularly liked the one above. Crescent-lit by the Sun, Enceladus’ night side is seen bathed in the dimmer glow of reflected light off Saturn and its rings. Dead-center is the 6.5-mile-wide crater Bahman, surrounded by a wrinkly field of cracks and troughs in the moon’s highly-reflective icy surface.
