The Aram Chaos region of Mars, as seen by the HiRISE camera on board NASA's Mars Reconnaissance Orbiter (NASA) There’s a military operation on Mars! How do we know this? Psychics — or “military grade remote viewers” as they like to be called — “saw” it, and...

For this special little planet, today has been a very big day. Although we’ve speculated that planets the size of Earth must exist elsewhere in the cosmos, it wasn’t until one of the co-investigators working with the Kepler Space Telescope said he had statistical evidence that worlds of...

Quite frankly, I’m stunned. An Australian amateur astronomer has just observed his second ‘once-in-a-lifetime’ event: an impact in the atmosphere of Jupiter. Phil Plait was very quick to get the news out, describing it as a “major coincidence,” and he ain’t wrong! Anthony...

In its haste to become the first newspaper to print the “NASA: Evidence of Life on Mars” headline, the UK’s Sun website caused a stir last week. Not only was this headline incorrect, it was a wee bit irresponsible. For starters, no evidence for life has been found on the Red Planet....

Sorry Spirit, you're not coming home (see the full xkcd comic strip). As far as space missions go, you couldn’t find a better epic tale than that of Mars Expedition Rover Spirit. Designed to last 3 months, roved for six years; lost the use of a wheel, turned it into a nifty trench-digging tool;...

Which planet does Tethys orbit again? I do admit, I’m terrible with names, but I never forget a face. In this case, the face I didn’t forget was a little moon orbiting Saturn (it’s the one that looks like the Death Star from Star Wars). However, after seeing this photo, I doubt I’ll...

The strange objects orbiting the two stars could be mangled white dwarfs... but the jury is still out (NASA) The first results from NASA’s Kepler exoplanet hunter are in and a perplexing early result has been announced. Yes, the space telescope is working fine, and no, it hasn’t spotted an...

NASA’s Mars Exploration Rover Spirit is suffering from amnesia, again. This is hardly surprising if we consider that the lifespan of Spirit should have been 3 months, the fact that it has lasted 69 months (so far) is nothing short of miraculous. In rover-mission-lifetime years, doesn’t...

The 6 meter-wide boulder as imaged by HiRISE (to supersize the pic, click on it - 9MB) It may only be a large rock, but images like this drive home the significance of the HiRISE instrument on board NASA’s Mars Reconnaissance Orbiter; it enables us to see recent geological activity on a planet...

Subliming ice from the crater edge (NASA/JPL/University of Arizona) This image looks like the frosted top of an over-baked muffin, but it’s actually the side of a crater on Mars covered with ice. Taken by NASA’s Mars Reconnaissance Orbiter (MRO) High Resolution Imaging Science Experiment...
