Galaxy Zoo Two

It’s back, and better than ever before. Now you can help classify galaxies in even more detail, but still with the excitement of exploring the cosmos and helping expend human knowledge further.

Take part here.

But to see some great evidence of why it’s helpful to take part see this page. It shows galaxies never before seen and certainly not categorised neatly divided up into lots of categories. The “anything odd” section has some really interesting objects in. More info from the Galaxy zoo blog here.

Mars goes Google.

The beautiful Google Earth program has gone Martian. The planet Mars is now explorable in full 3D (not just an overlay).

See Olympus Mons rise above the distant horizon or fly down Valles Marines in a full 3D projection. You can even follow the landers progresses, and view some of the panaromic high resolution shots just as the rovers Spirit or Opportunity saw them.

This video from the official “unoffical” Google Earth blog clearly shows of some of the best features:

Just download Google Earth, click on the planet button in the toolbar and select Mars. Some informative pictures here too:

Martian trippers enjoy storm free journey

Great news for all Martian wannabes.

The trip to Mars can be made much safer with the realisation of a “Force Field”. This will drastically cut down the problems the solar wind can cause, especially when a solar storm occurs.

The high speed particles flowing from the Sun during a Solar Storm can cause serious medical problems for the astronauts, so using technology developed during Fusion research it was found that a “magnetic bubble” can be used to envelope the spaceship and all and protect them in the same way the Earth is protected from the Solar Winds.

Becoming an intergalatic explorer 2 – Visit the zoo


I’m sure you’ll remember my last post about becoming an intergalactic explorer, well now there’s a new project to help you explore the cosmos but in a similar way to the last one.

The project is:
http://www.galaxyzoo.org/

You’ll be rummaging through the Slaon Digital sky survey – a huge database of galactic images. Your mission is to find the images that look like galaxies then pick a category for them. Most of these images haven’t been seen by anyone else.

THe image above is an example. it looks pretty good, and I’ve chosen an anti-clockwise spiral. (I hope you agree…)

Have fun and find something interesting…

UPDATE:
Here’s a few nice looking galaxies I’ve come across:
One, two, three and four.

Earth II? Or would you prefer "GLIESE 581 C"?

A planet which is suspected to be the closet resemblance to Earth has been seen, and its a neighbour.

Just 20 light years away (almost in touching distance) around the star Gliese 581 is a planet not much bigger than Earth (1.5x). It orbits much closer to its star than the Earth does to the Sun, and takes only 13 “Earth” days to orbit. However, the star Gliese is much smaller and weaker than the Sun so a planet orbiting that close would actually have temperatures very similair to Earth, in fact within the temperature limit that would allow liquid water to exist on the surface.

All this has been estimated from the slight wobble of the star seen from Earth, which is created when a something large orbits around, although the effect is very small.

This would make an ideal candidate for the upcoming planet hunting space telescopes, designed to image planets around stars – unfortunately, we still have to wait several decades for this to be achieved…
