I love to play pub quiz machines, they are now a common feature of UK pubs. Now I can play any time I like online at the Triviala web site. Triviala is a free to play fast-paced trivia and quiz site.

As you complete the trivia quizzes you win 'crowns'. Use these crowns to enter daily and weekly prize draws. There is £5,000 to be won each month! The more crowns you win by answering the Trivia Quiz questions the more times you can enter the draws.

There are different ways to play. Chose to answer 30 quick fire questions, or one question a day. Every way you win.

Quizzes cover a wide range of subjects. Everything from general knowledge to highly specialized subjects. You can find a quiz on your favourite singer, TV show or movie. Test your first aid knowledge or details of the British Monarchy.

There are other ways of gaining crowns such as creating and submitting your own trivia quizzes. Upload a photo or invite your friends to join in the fun. And there are more ways to win still, theses you will have to discover for yourself.

So, if you want a fun and simple way to keep the grey matter fizzing. If you want to win money by playing great games then Triviala is the place for you.

After three months offline, the European Space Agency's Mars Webcam is back, with much improved IT infrastructure support.

The Mars Webcam is officially called "The Mars Express Visual Monitoring Camera (VMC)." Its original purpose was to monitor the separation from the Mars Express of the ill-fated Beagle lander. It is not a scientific instrument, but a simple, low-tech camera. It provides fantastic views of the Red Planet. Including crescent views not seen from Earth.

ESA's deep space probe, Mars Express, has been on the other side of the Sun recently, so there have been no pictures from the VMC. It started sending pictures again mid-February.

ESA have now set up the IT support so that pictures form the VMC are uploaded automatically to its own blog as they arrive. Depending on what other data is in the transmission queue, a picture from the VMC could be available online within an hour of it being taken.

These images are raw and unprocessed. This is where you could help. ESA are looking for anyone to process the images or even identify landmarks on the surface.

If you are looking to make a contribution to planetary science go to the Mars Express Visual Monitoring Camera blog and see how you can help.

Ian O'Neill has edited the Carnival of Space 96 on astroengine.com.

I very much recommend a surf of the carnival. As usual it is very interesting. In terms of verity and quality the Carnival of Space is one of the best carnivals I see.
