New projects for Astronomy Education and Outreach

Finally , after a busy two weeks of activities associated with the Manchester Science Festival I have finally gotten round to updating my blog.

I've decided to make a personal note to myself to make a long list of projects I'm planning on developing over the course of the run up to the International Year of Astronomy and write it here so that I don't forget because with everything being so busy at the moment my brain is like a sieve (eek!) so here goes:

1. Set up Astronomy Education Web Portal and interactive Virtual Learning Environment which allows educators, learners and wider community to engage in astronom and space related resources and information.

2. Set up creation and delivery of educational projects, training courses, etc in the form on formal and informal learning activities.

(New note to self, how many times can I fit the word "activities" in one post?!)

3. Follow up on all of the ideas and initiatives I agreed to get involved in at the CAP 07 conference in Athens last month.

4. Add to the blog a real sky diary so that visitors can actually get to read a sky diary as well as a rambling blog : )

So, here is the Sky Diary!

Here is a nice story I found on BBC News 24's site:

Holmes is becoming a 2nd magnitude object in the night sky at the moment by the way

Comet Holmes brightens in retreat

An explosion on a distant comet, Holmes, has been examined by UK astronomers using the Isaac Newton Telescope (INT) on the Canary Islands.
The explosion was so big that the comet brightened by a factor of a million; and it can now be seen from the Northern Hemisphere with the naked eye.

Holmes is currently moving away from the Sun, and is almost midway between the orbits of Mars and Jupiter.

It was amateur astronomers who alerted the professionals to the brightening.

One of the UK observation team, Professor Alan Fitzsimmons of Queen's University, Belfast, said it was a once in a lifetime event.

"Although comets have been seen to undergo outbursts before, the scale of this dwarfed anything seen in the past century," he said.

The images from the INT show an expanding circular cloud of gas and dust emanating from the nucleus of the comet, together with a brighter cloud of material.

Professor Fitzsimmons explained: "From these images, we can see the ejecta moving away from the comet at 2,000km per hour (1,300 miles per hour). The total amount of material ejected is probably about 1% of the total mass of the comet.

"On a smaller scale, it is like the Earth suddenly threw off its crust."

It is not clear what caused this explosive event - especially since it is moving away from the Sun's energetic influence.

One possibility is that the comet was hit by a meteoroid. More probably, there has been a build-up of gas under part of the surface that catastrophically ruptured the surface last week.

Comet Holmes is a regular visitor to the inner Solar System. It takes 6.9 years to orbit the Sun once. It made its closest approach to our star last May, passing by at some 300 million km (190 million miles).

To the naked eye, Holmes appears as a fuzzy yellow dot in the night sky in the Perseus Constellation.

Welcome to Sotira's Cosmic Diary

Well, here is the first of my postings for the science education based activities I have been delivering over the past few months.

The main aim of this blog is to act as a contribution to the International Year of Astronomy 2009's Global Cornerstone Projects, one of which being a "Cosmic Diary".

I will tell you more about this in later posts but for now here was how my day went today.

The activity for today was the second day at the Touchstones Museum in Rochdale, Greater Manchester which is one of the educational events for the Manchester Science Festival. There are not that many visitor attractions in Rochdale, especially for kids, and the children attending the session today were so enthused they didn't want to leave!

In fact, at one point during the day, one mum asked if I could keep an eye on her kids for half an hour while she nipped off to ASDA to do her shopping. Charming!

The session for today was the Forceworks exhibit that is part of Glasgow Science Museums outreach activities. It is a fully hands-on museum piece that allows children to conduct a series of simple experiments to investigate forces. The experiments have been specially designed for Key Stage 2 children and supports programmes of study and QCA schemes of work in Science (UK curriculum). The experiments are wrapped around investigating principles such as magnetism, pressure and gravity.
