Here’s a view of our home planet and lovely Moon captured from 127 million miles away by NASA’s Mars Reconnaissance Orbiter on November 20, 2016. The sunlit part of Earth shows eastern Asia, the Indian Ocean, and Australia with ice-covered Antarctica visible as a bright white spot. The Moon has been brightened in this image, since it would…

NASA Announces Two New Exploration Missions
Happy New Year! Just four days into 2017 NASA announced its pick for two new Discovery missions to explore our solar system: one to investigate a few of the “Trojan” asteroids that Jupiter has gathered into its orbit with its mighty gravity, and another to visit the remains of an ancient planet’s metallic core! “These are true…
It’s the Beginning of the End for Cassini (But the Pictures Will Be Awesome)
After more than twelve years in orbit around Saturn, NASA’s Cassini spacecraft is now in its final year of operation…and newly-positioned in an orbit that will send it soaring high over the planet’s north pole as well as close by the outer edge of its glorious shining rings. Over the course of 20 week-long “ring-grazing orbits” — the…

What’s So Super About a Supermoon?
You’ve probably heard the news or read the headlines: the full Moon on November 14 will be a “supermoon,” and in fact the biggest and brightest one since 1948 and until 2034. But what does that really mean and what can we expect to see in the night sky? In all honesty it won’t be…
More Moons For Uranus?
The distant ice giant Uranus may not have been visited by a spacecraft since Voyager 2’s “Grand Tour” flyby in 1986 but the data gathered then is still being used today to make new discoveries. Most recently, researchers think they have found evidence of two previously unknown moons around Uranus, potentially bringing the planet’s count up…
With One More Comet Landing Rosetta’s “Rock and Roll” Mission is Ended
Rosetta is down. I repeat: Rosetta is down. This morning, Sept. 30, 2016, just after 10:39 UTC (6:39 a.m. EDT) ESA’s Rosetta spacecraft ended its mission with an impact onto the surface of the comet 67P/Churyumov-Gerasimenko. The descent, begun with a final burn of its thrusters about 14 hours earlier, was slow, stately, and deliberate, but even…

Juno Sends Back Its First Pictures of Jupiter’s North Pole; “Like Nothing We Have Seen Before”
Thanks to NASA’s Juno spacecraft we now have our best views yet of the north pole of our Solar System’s largest planet and they’re “hardly recognizable as Jupiter” according to the mission’s lead scientist!

Round and round they go… the animation above, made from 14 raw images taken by NASA’s Cassini spacecraft on August 23, 2016, shows the moons Prometheus and Atlas orbiting Saturn within the Roche Division gap between its A (top right) and F (center) rings. The gravitational tug of Prometheus (92 miles / 148 km long) is strong…
