ESA’s Rosetta mission has has a long a interesting journey through the solar system on its way to its final target Comet Churyumov-Gerasimenko. Launched in 2004 the probe has completed flybys of Earth twice and Mars one and already visited an asteroid as well as taking some fantastic astro-images on the way.

Today it passes asteroid 21 Lutetia at a distance of about 3,000 km. The closest approach takes place at about 1645 BST but as it is happening at a distance of 450 million km from Earth it will take some time for the pictures to be returned and processed. It's unlikely we'll see anything on the web before ten o'clock tonight.


This image from the ESA Rosetta team shows the asteroid seen from the probe yesterday at a distance of 2 million km. More information and updates are available on the Rosetta Blog.



The asteroid itself is relatively large, about 100km in diameter and although classed as an 'M type' asteroid has some characteristics of the much older 'C type' asteroids. Hence there is a bit of a mystery for astronomers to solve from the data Rosetta returns. It is also a great opportunity to test out all the instruments before the final comet encounter in 2014.

The Solar System needs your help . . .

Last year Kendal's Eddington Astronomical Society held a really successful scale model solar system event at Kendal Castle. I went along to help out and it was a really good day. See the video below. .




They are repeating the event this year, in the town centre this time. The aim is to bring the event to even more members of the public. The event takes place on 14th August.

To do this Stuart and EAS could really use your help. They need as people as possible to turn up for as long as you can spare to 'man a planet' as it were. You don't need to be an expert and will be given all the information and equipment you need. The idea is just to have people on hand to talk to the public, answer questions or simply point them in the right direction for more information.

If you think you could help out please get in touch with either myself or Stuart and offer your services. If you can't help then please encourage friends, family and colleagues to go along learn something.

Planck produces an new map of the microwave sky

ESA Planck instrument has been observing the sky at microwave wavelengths for 12 months now. This newly released image shows the microwave radiation from both the cosmic background radiation and the milky way.

The next task for the team is to use the information from Planck's detectors a nine different wavelengths to remove the Milky Way emissions and produced the most detailed map of the cosmic microwave background yet.

June 2010 Meeting Report

A very big thank you to Professor Ryan Hickox, an STFC Fellow at the University of Durham, who came to speak to us about the Growth of Galaxies and Supermassive Black Holes.

Ryan flew in from Paris, having spent several days reviewing the latest data from the Herschel space telescope.

If you'd like to know more about Ryan check out http://www.dur.ac.uk/ryan.hickox/

There was much interest in the talk, which appealed to young and advanced with plenty of opportunity for questions (and a pint in the pub after the talk)!

There will be no meetings in July or August due to summer holidays. So the next society meeting will be 28th September 2010.
