New Horizons sure is! With just over two weeks to go before the first-ever (and I repeat: EVER!) visit to Pluto and its family of moons the excitement has really ramped up exponentially, especially considering the increasingly detailed views of Pluto and Charon that the spacecraft has been capturing on approach. No longer just a…

Bright Spots Galore and a Mystery Mountain: Ceres Gets Curiouser and Curiouser
The more NASA’s Dawn spacecraft observes of the dwarf planet Ceres the weirder it seems to get. Closer investigations of the “bright spots” first seen in Hubble images in 2003 and then in Dawn images upon approach during the first few months of 2015 show an ever-increasing cluster of smaller bright areas (eight at last count) and…
Scientists Squeeze Methane Out Of Martian Meteorites
One of the biggest clues to finding evidence of life on Mars – past or present – has been the existence of methane, an organic compound that is the principal component of natural gas here on Earth. Methane can arise via both biological and non-biological processes, but in both cases it can be used as…
Infographic: Why Would We Mine the Moon?
Our Moon is more than just some pretty decoration for the night sky and a place to plant a few flags – it’s also a potential source of valuable raw materials that could someday be used for energy and engineering both on Earth and in space. If you saw the movie Moon (and if you haven’t…
Do You See Bright Spots on Ceres? Icy Bright Spots on Ceres.
Ok that was a bad pun for a headline but this IS the best image yet from NASA’s Dawn spacecraft of the curious bright spots on the dwarf planet Ceres, which have been puzzled over by scientists since they were first spotted in Hubble observations in Dec. 2003. And even with this incredible new view…
Curiosity Gazes on Mars’ Moon Phobos
Do you love to look up at the Moon? Well so does NASA’s Curiosity rover! Feel free to correct me if I’m wrong (I have not confirmed this) but this appears to be an image of Phobos, the larger of Mars’ two small moons, imaged by Curiosity’s Mastcam on mission Sol 1002 (June 1, 2015)….
Watch the Exciting First Trailer for The Martian
The first trailer for The Martian is out, a new film by Ridley Scott based on the best-selling novel of the same name by Andy Weir. (If you haven’t read The Martian you really must check it out – it’s a fantastic “science-reality” adventure about one stranded astronaut’s struggle to survive on Mars and NASA’s attempt…
How Bright is Daytime on Pluto?
We all know that Pluto is very far from the Sun, on average about 40 times as far away from it as Earth is, and as such it is very cold and dark. But just how dark is it on Pluto? If you were an astronaut walking around on Pluto would the Sun really just…
Here’s to 50 Years of American Spacewalks
Today we mark the 50th anniversary of American spacewalks, or EVAs (for extra-vehicular activity), the first of which was performed by NASA astronaut Edward H. White II in Earth orbit on June 3, 1965 during the Gemini IV mission. While the United States had been beaten in the spacewalk race by the Soviet Union by almost three months…
Hyperion in Color: a Composite from Cassini’s Last Visit
Here’s a color view of Hyperion made from raw images acquired in optical wavelengths by Cassini during its flyby on May 31, 2015 – the last pass it will make by this moon during its mission. Read more about this flyby here.
