Moons of Saturn

On July 29, 2011 the Cassini spacecraft's narrow-angle camera took this snapshot and captured 5 of Saturn's moons, from just above the ringplane. Left to right are small moons Janus and Pandora respectively 179 and 81 kilometers across, shiny 504 kilometer diameter Enceladus, and Mimas, 396 kilometers across, seen just next to Rhea.

The Shadow of Io

During a recent perijove pass, Juno caught an absolutely incredible image of Io's shadow cast upon Jupiter.😲😍

Unless it's actually millions of monoliths devouring Jupiter's atmosphere. Which is, frankly, equally as likely.

Parker Skims the Sun

NASA’s Parker Solar Probe is currently making its third of 24 dives through the sun’s corona this week: https://www.space.com/parker-solar-probe-third-sun-flyby.html. Every loop sends the spacecraft deeper into the corona, increasing the risk to the craft but also the reward in the form of bucketloads of scientific data.

Spitzer's Sweet 16

"NASA launched its Spitzer Space Telescope into orbit around the Sun on Aug. 25, 2003. Since then, the observatory has been lifting the veil on the wonders of the cosmos, from our own solar system to faraway galaxies, using infrared light.

Managed by NASA's Jet Propulsion Laboratory in Pasadena, California, Spitzer enabled scientists to confirm the presence of seven rocky, Earth-size planets in the TRAPPIST-1 system. The telescope has also provided weather maps of hot, gaseous exoplanets and revealed a hidden ring around Saturn. It has illuminated hidden collections of dust in a wide variety of locations, including cosmic nebulas (clouds of gas and dust in space), where young stars form, and swirling galaxies. Spitzer has additionally investigated some of the universe's oldest galaxies and stared at the black hole at the center of the Milky Way.

Spitzer's primary mission lasted five-and-a-half years and ended when it ran out of the liquid helium coolant necessary to operate two of its three instruments. But its passive-cooling design has allowed part of its third instrument to continue operating for more than 10 additional years. The mission is scheduled to end on Jan. 30, 2020.

In honor of Spitzer's Sweet 16 in space, here are 16 amazing images from the mission.": http://www.spitzer.caltech.edu/news/2195-ssc2019-15-Sixteen-Images-for-Spitzer-s-Sweet-16

The Great Red Spot

This new Hubble Space Telescope view of Jupiter, taken on June 27, 2019, reveals the giant planet's trademark Great Red Spot, and a more intense color palette in the clouds swirling in Jupiter's turbulent atmosphere than seen in previous years. The colors, and their changes, provide important clues to ongoing processes in Jupiter's atmosphere. More info: https://www.nasa.gov/feature/goddard/2019/hubble-new-portrait-of-jupiter

Curiosity, Checking In

An update from the indomnitable Mars rover Curiosity: “Can't stop. Won't stop. I've been exploring #Mars for seven years, traveled 13 miles (21 km), climbed 1,207 feet (368 m), found conditions on ancient Mars were favorable for life as we know it, and I'm not done yet. Here's what's new (plus a 360 view): https://go.nasa.gov/2YtGgMg

Statue of Liberty Nebula

Star Forming Region Without Stars: By digitally removing the stars, this image showcases dense knots of dark interstellar dust, fields of glowing hydrogen gas ionized by these stars, and great loops of gas expelled by dying stars.

Allegedly some people think this region resembles a weeping angle, but…no. Just no. #shudder

To the Moon and Beyond

Everything you ever wanted to know about Artemis, the lunar gateway and other lunar plans - and then some: https://www.bbc.co.uk/…/e…/nkzysaP3pB/to-the-moon-and-beyond.

I do feel like the article minimizes the near-certain role SpaceX and/or Blue Origin rockets and modules are going to play, in favor of presenting the official NASA line (Orion, SLS). But otherwise it's an informative, wide-ranging article (without getting into the nitty-gritty technical details).

Map of 4,000+ Exoplanets

NASA has dropped an insane map of 4,000 planets outside our solar system: https://www.cnet.com/…/nasa-drops-insane-map-of-4000-plane…/

The video is absolutely worth watching: https://www.youtube.com/watch?time_continue=8&v=aiFD_LBx2nM. It's only a minute long and is a great visualization of how exoplanet discovery just exploded in the last decade (go Kepler!📡✨).

New Lease on Life for the Voyagers

Voyagers 1 and 2 have the distinction of being in space for 42 years and still operating. And even though they’re 18 billion km (11 billion miles) from the Sun, they’re still valuable scientifically. But they’re running out of energy, and NASA has been working on how to stretch their remaining power for as long as possible.

Dragonfly is Headed to Titan

NASA has announced its next big "New Frontiers" mission: DRAGONFLY, a nuclear-powered drone/rotorcraft lander, will visit Titan, the only moon in the solar system with a dense atmosphere rich in nitrogen and carbon (and one of the coolest stellar bodies to boot), to search for the molecules of alien life.

Dragonfly will launch in 2026 and arrive at Titan in 2034.

Stunning Close-Up of Asteroid Bennu

NASA's OSIRIS-REx Spacecraft Takes Stunning Photo of Asteroid Bennu From Just 0.4 Miles Away. This image of asteroid Bennu was captured on Jun. 13, 2019, shortly after NASA’s OSIRIS-REx spacecraft executed its second orbital insertion maneuver. From the spacecraft’s vantage point in orbit, half of Bennu is sunlit and half is in shadow. At this distance, details as small as 1.6 ft (0.5 m) across can be resolved in the center of the image.

Bam! Fresh Crater Spied on Mars — and It Looks Spectacular

A small space rock crashed into the Red Planet's surface recently, producing a fresh crater that researchers estimate is 49 feet to 53 feet (15 to 16 meters) wide. The dramatic feature is clearly visible in a newly released image from NASA's Mars Reconnaissance Orbiter (MRO).
