At 3:34 p.m. EDT (19:34 UTC) today, April 30, 2015, after more than ten years in space – and four of them in orbit – the MESSENGER spacecraft’s operational life came to a conclusive end when it impacted the surface of Mercury, as planned. After revealing the surface of the innermost planet like no mission ever…

Is That an Ice Cap? New Horizons Detects First Details on Pluto
Taken from a distance of about 69 to 64 million miles – just about the distance between the Sun and Venus – the images that make up this animation were captured by the LORRI imaging instrument aboard the New Horizons spacecraft and show its first detection of surface features on Pluto, including what may be the bright reflection of…
Icy Tendrils in Saturn’s E Ring Traced Back to Enceladus
As the ice-encrusted moon Enceladus makes it way along its orbit around Saturn it gets repeatedly squeezed by the giant planet’s gravity, like a frozen stress ball with water-filled insides. This constant squeezing and relaxing generates friction heat in the moon’s crust, which could be responsible for keeping some of its internal water liquid and spraying…
New Horizons Has Caught Its First Color Pic of Pluto
In a historic first – just one of many that will be made over the next several months, to be sure! – the New Horizons spacecraft captured its first color image of Pluto and its partner/satellite Charon on April 9 from a distance of 71 million miles – about equivalent to that between Venus and…
What Can Hubble See? Find Out in This Music Video
Get into a little “Hubble trouble” with this music video by NPR’s Adam Cole, aka Skunk Bear. Produced in honor of the 25th anniversary of the space telescope’s launch aboard Discovery STS-31 on April 24, 1990, the video is a parody of Iggy Azalea’s “Trouble” and, in my opinion, surpasses it astronomically. (See what I did…
An Oblique View of Abedin Is One of MESSENGER’s Final Scenes
The 72-mile (116-km) -wide crater Adedin is seen at an oblique angle in this mosaic made from images acquired by NASA’s MESSENGER spacecraft. The angle highlights the crater’s central peak complex which surrounds a shallow depression that could have a volcanic origin, as well as fine cracks in the floor of its basin and a…
Dawn Emerges from the Darkness to Send New Views of Ceres
After a brief period of silence (due to its position on the dwarf planet’s night side) NASA’s Dawn spacecraft is now sending back images from orbit around Ceres, revealing amazing details of its surface and giving another look at those mystery “bright spots” that have intrigued scientists since their discovery in 2003. The animation above shows Ceres’…
Supplement Your Day With This Calcium Image of the Sun
Our Sun may be made up of 98% hydrogen and helium but the remaining two percent comprises many other elements, detectable by their unique absorption lines within the gamut of white light we receive on Earth. One of those elements is calcium, which exists in ionized form in relatively tiny amounts in the Sun’s chromosphere…
Space Is Hard, and So Are the Decks of Drone Ships
On Tuesday, April 14, SpaceX launched its Dragon cargo vehicle aboard a Falcon 9 rocket from Cape Canaveral, sending over two tons of supplies up to the crew of the ISS. While the launch was a success and everything went smoothly for Dragon’s CRS-6 mission (despite a single day’s launch delay due to weather) the…
Cassini Spots the Sombrero Galaxy from Saturn
We’re all used to seeing fantastic images of Saturn and its family of moons from NASA’s Cassini spacecraft, which has spent the last decade in orbit around the ringed world. But every now and then Cassini aims its cameras outwards, capturing images of the sky beyond Saturn – just like we might look up at the…
Curious Stains on Mars’ Summer Slopes Continue to be Seen
As the midsummer Sun beats down on the southern mountains of Mars, bringing daytime temperatures soaring up to a balmy 25ºC (77ºF), some of their slopes become darkened with long, rusty stains that may be the result of water seeping out from just below the surface. The image above, captured by the HiRISE camera aboard NASA’s Mars Reconnaissance Orbiter on Feb….
Water Water Everywhere
Everyone knows that Earth is a “water-world,” with oceans covering 71% of its surface and at least as much contained within our planet’s mantle deep below its crust. But there’s also liquid water to be found elsewhere in the Solar System: on Mars, on the dwarf planets Ceres and Pluto, and also on the icy moons of Jupiter,…
