A comparison between an observation of the sun using the ATA's 2.75 GHz band (left) and SOHO's 195A filter. Both are near-simultaneous observations on Oct. 1, 2009 (Saint-Hilaire et al., 2011). And no, “aliens” isn’t the answer. The Allen Telescope Array (ATA), located near...

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...

Some galaxies undergo a rapid star formation phase, losing stellar gases to intergalactic space, others choose to recycle, thereby extending their star forming lifespans (NASA, ESA, and A. Feild (STScI)) It sounds like an over-hyped public service announcement: If you don’t recycle, you’ll...

Stars of the Northern Hemisphere, Ashland Astronomy Studio Imagine the scene: I’m having a romantic walk on a clear night with my wife along the beach. We see a brief flash of light and Deb says, “Hey, a meteor!” I then proceed to tell her that most meteors are actually no bigger than...

"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...

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...

Where is this mystical land? (NASA/ESA/HST). Sometimes, words are not enough to describe views of the universe when captured through the lens of the Hubble Space Telescope. This is one of those moments. Kicking off its 20th anniversary (yes, that super-sized telescope has been in space that long —...

The Orion Nebula's star-forming region (NASA). Firstly, apologies that it’s been over a month since last posting to Astroengine.com. Call it slacking off, call it a sabbatical, either way, it’s not good. I’ve actually prepared several half-finished articles, but I just never got around...

Something rather bizarre was observed in the asteroid belt on January 6. Ray Villard at Discovery News has just posted an exciting article about the discovery of a comet… but it’s not your average, run-of-the-mill kinda comet. This comet appears to orbit the Sun, embedded in the asteroid...

This week has been a horrid few days for UK physics. The Science and Technology Facilities Council (STFC) announced on Wednesday that it was going to plug a hole in their funding deficit by withdrawing the UK’s participation in a number of astronomy, nuclear and particle physics projects. This...
