A curiously shaped Mars dune (NASA/JPL/University of Arizona) Is that a bird? Yes, I can see a bird! A bird on Mars! Aliens must have created it to send us a message! Actually, no, it’s a curiously shaped dune on the Martian surface. My subconscious brain has just processed a familiar shape and...

The strange cloud-like protursion above Mars' limb (around the 1 o'clock point). Credit: Wayne Jaeschke. Last week, amateur astronomer Wayne Jaeschke noticed something peculiar in his observations of Mars — there appeared to be a cloud-like structure hanging above the limb of the planet....

A menagerie of strange divots (NASA/HiRISE/Univ. of Arizona) As 2011 draws to a close, it’s time to reflect on my absenteeism from Astroengine. But it’s not my fault, I’ve been typing like a madman for these guys. But that’s enough excuses, 2012 promises to be a huge year for...

An artist's impression of a lone exoplanet transiting its parent star. There are now 700 confirmed alien worlds orbiting other stars (ESO) On Friday, the Extrasolar Planets Encyclopedia registered more than 700 confirmed exoplanets. Although this is an amazing milestone, it won’t be long until...

"That's no sunspot." Assuming Star Trek‘s Borg Collective went into overdrive and decided to build a huge cube a few thousand miles wide, then yes, the exoplanet-hunting Kepler space telescope should be able to spot it. But how could Kepler distinguish a cube from a nice spherical...

Exoplanets may reveal their location through radio emissions (NASA) In 2009, I wrote about a fascinating idea: in the hunt for “Earth-like” exoplanets, perhaps we could detect the radio emissions from a distant world possessing a magnetosphere. This basically builds on the premise that planets...

It's a chocolate Mars rover! Photo credit and cake-making skills: Will Gater OK, so Astroengine has been a little quiet of late due to some uber-cool space news writing over at Discovery News, but to kick off an era of increased productivity (and not just Photoshop fun), I just had to share this...

"A big rusty transporter came over the hill and the Jawas sold it for scrap metal..." -- Paul Quinn NASA is giving Mars rover Spirit one more month to signal that she’s still alive before search operations are scaled back and attention shifted to her sister rover Opportunity. Unfortunately,...

"Dad?" A scene from War of the Worlds. This rather outlandish, sci-fi notion comes straight from the fertile minds of researchers from MIT, the Massachusetts General Hospital and Harvard University who are proposing a biology experiment that could be sent on a future Mars surface mission....
