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...

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...

DNA and amino acids. Not just a terrestrial thing? (©CG4TV) This is probably one of the biggest questions that hang over science fiction story lines: Will extraterrestrials have any resemblance to Life As We Know It™? To be honest, to toy with the thought of anything other than carbon-based life...

Searching for Earth-like exoplanets (© Mark Garlick*) Is there a new way to hunt for habitable Earth-like exoplanets? According to a US Naval Research Laboratory researcher there is an obvious, yet ingenious, way of listening for these worlds. Like most Earth-like exoplanet searches, we are looking...

The Delta II ignition: Kepler began its mission on Friday at 10:49pm EST (© United Launch Alliance) In the 17th Century, Johannes Kepler defined the laws of planetary motion around our star. Now the Kepler space telescope will define the motion of alien worlds around distant stars. Go find us some exoplanets! I...

Right: The Kepler space telescope launches onboard a Delta II rocket from Cape Canaveral, March 2009 (NASA) Kepler, the exoplanet-hunting space telescope, successfully launched from Cape...

The 1998 archive Hubble image of HR 8799 after image analysis - one of the star's exoplanets have been resolved (D. Lafrenière et al., ApJ Letters) What’s just as exciting as directly imaging an exoplanet in a new observing campaign? To discover an exoplanet in an old observing campaign. Like...

Can astronomers really detect exomoons? Exomoon: The natural satellite of an exoplanet. Before today, I hadn’t heard anything about the possibility of looking for moons orbiting planets in other star systems. Sorry, exomoons orbiting exoplanets in other star systems. But a British astronomer has...

It would appear that yet another extrasolar planet has been directly observed! Only last week, the Hubble Space Telescope released news that it had spotted an exoplanet orbiting the star Fomalhaut. This is the first ever direct observation of an exoplanet in optical wavelengths. On the same day, joint...

The day has finally come. We now have direct, infrared and optical observations of planets orbiting other stars. Yesterday, reports from two independent sources surfaced, one from the Gemini and Keck II observatories and the second from the Hubble Space Telescope. Brace yourself for an awe-inspiring...
