, first observed by Galileo, normally follow an 11-year cycle. We are into a few years into (recorded) cycle number 24 but according to NASA it's looking rather underpowered
. Nobody is certain exactly what the consequences will be, but one distinct possibility is a cold period
; a previous low in solar activity, the Maunder minimum
, is correlated with a brief Little Ice Age
. Nobody really knows how this unusual solar weather pattern might interact with human-caused climate change. Previously
, albeit somewhat controversially.

have just published a paper entitled "Gliese 581d is the 1st discovered terrestrial-mass exoplanet in the habitable zone", claiming that their computer model suggests the exoplanet
"will have a stable atmosphere and surface liquid water for a wide range of plausible cases."
We've discovered a lot
of exoplanets. And there are a lot
to help you keep track. Previously.

In 2009, to mark the 400th anniversary of Galileo first turning a telescope skywards, Radio New Zealand National, in partnership with the Royal Society of New Zealand, released this kickin' series of five lectures spanning the evolution of cosmology, extra-solar planets, near-earth objects, the nascent field of neutrino astronomy and prospects for the future as the Square Kilometre Array radio telescope comes online early in the next decade. It's a great listen and best of all, it's free to download as MP3 or Ogg Vorbis!

Where's Tyche, the 10th 9th planet? Getting the full story.
John Matese and Daniel Whitmire of the University of Louisiana at Lafayette recently made the news when they announced the possible discovery of a gas giant planet they named Tyche
in the Oort Cloud, at the extreme edge of the Solar System (previously
). Now ars electronica breaks down the evidence behind the announcement, what can be done to confirm or disprove its existence & how long it could take.

"The theme of this blog is not only and obviously space, but in particular places in space that a person might theoretically be able to one day visit. So for the most part, nebula, galaxies and the like are not a part of this forum. I tend to focus on “terrestrial” places or places that host such places. I suppose I would like to find out more about these places that we may one day inhabit or simply visit."
Hat tip to Nice Guy Mike!

may just be the most peaceful, beautiful 5-1/2 minutes of your entire day: An audio slideshow look at some of the winning images, guided by one of the judges, of the Royal Observatory in Greenwich's 2010 Astronomy Photographer of the Year competition. Interested in "giving it a go"? Here are some guides
to photographing different aspects of the night sky.
