Excellent new animation from NASA

This video shows a recreation of the way in which the Moon is thought to have formed, and how it got all the features we see today.

ISSP session 2

The ISSP finished in high style today, with practical work on the scale of the solar system, impact crater formation and the real size of interstellar distances. I was thrilled to hear students using terms like "you can see the shockwave moving through the impact site" when we were recreating craters, and it was a great pleasure to spend time with so many intelligent, interested young people.

I hope very much to see some of you at our next observatory open evening!

Thank you for coming!

It was a bit cloudy, but at least it wasn't too cold! We got to see a few things on our target list, including Venus, which showed as a perfect half-moon shape, Jupiter and some fine cloud belts and Mars, with a brilliant white polar cap showing clearly against the orange desert soils of that cold, arid world.

In the photograph below, you can see the Cooke telescope pointing at Venus through the observatory hatch, captured in a one second long exposure.

The full Moon put in a showing, with this view as it rose on the eastern horizon.

Full Moon

There is something really magnificent about the sight of the full Moon sailing up into the sky. For thousands of years people have responded to this dramatic spectacular in the arts, with music, paintings, poetry and even architecture relating to the phenomenon.

Here is a lovely picture taken this week by Verena Kummel, showing clearly the ancient (three billion years old) dark seas overlaid with more recent impact craters.

Can you name the seas? In this picture you can find; The Mare Crisium, Mare Frigoris, Mare Tranquillitatis, Mare Serenitatis, Mare Fecunditatis, Mare Humorum, Mare Vaporum, Mare Imbium, Oceanus Procellarum, Mare Nubium, and many more!

Observatory session, Thursday 8th March, 7.30 - 8.30pm

If the sky is clear, I will open up the observatory on the date shown. Mars has just reached opposition, tucked under Leo's paws and should be a good object to look for, but the full Moon will make it hard to see much more than the brightest few stars otherwise. For the interested, I'll go through the basics of setting up the portable Meade telescope so that you can hire it if you'd like to, and we'll put it through its paces on setting Jupiter/Venus.

Finally, we can try to catch a glimpse of comet Garradd with binoculars, and have a go at taking a picture of it with the Nikon camera.

mail me if you can make it!
