Nasa have released this beautiful time-lapse composite video of Lunar Reconnaissance Orbiter data showing the far side of the moon

https://www.youtube.com/watch?v=jdkMHkF7BaA

It's both beautiful and disconcerting to see the Earth whizzing about in the background of space

And according to the Bad Astronomer its fairly accurate he gives a breakdown on it here :-

For anyone lucky enough to live in northern Europe, the Aurora Borealis is probably a relative common sight, but the word from Astronomers is that the Northern Lights are very likely to be visible from Scotland and northern England this evening in the hours before midnight, due to the Sun's lively activity at the moment.

If it's a clear night where you live, pop outside after 8pm and look north :wink: I've never been lucky enough to see this beautiful sight in person, but if anyone does see it tonight or has seen it in the past, please feel free to tell us about it or post pictures! :D

Hope you guys are wrapped up warmly!?!

P.S. Didn't know what thread to post this under as we don't have a "Weather" topic thread, but as it's from NASA, I plumped for an astronomy thread instead :)

The guys with the show ploughs did a rather erratic job although some were obviously drunk.

"A collection of vintage photographs by Nasa's pioneering astronauts goes under the hammer at Bloomsbury Auctions in London on 26 February 2015" - now that's an auction I would love to be at!!

Mind you, I'd have to win on this Friday's Euromillions lottery to be able to afford them, judging by the guide prices of between £300 - £10,000 per photograph! :roll:

I've paid more than that for photographs but it did include the negatives.

NASA has released some great footage taken of Ceres, a dwarf planet and the largest object in the asteroid belt between Mars and Jupiter, captured by the Dawn spacecraft mission as it nears Ceres. It shows a series of photos taken through a complete rotation of the dwarf planet, which takes 9 hours in real-time.

However, NASA admits that everyone is baffled by two, very unexpected, very bright spots that appear on Ceres' surface and can only speculate as to the cause....... aliens, reflective mineral deposits or is this where Errol and his dragon Queen went perhaps.....?

The Truth is out there.......... :wink:

:sunny: :sunny: Date for the diary: :sunny: :sunny:

On the morning of Friday 20th of March the UK will experience the best solar eclipse since 1999 :sunny:

The Earth is in a unique position in the Solar system as our Moon is 400 times smaller than the Sun, but 400 times nearer the Earth, which is why we are lucky enough to experience a a solar eclipse when there is an alignment. The further north you are in the UK, the greater the totality of the eclipse you will see - you will need to be up in the Faroe Islands off the north coast of Scotland to see a 100% total eclipse, but even down in London there will be circa 86% of totality, so the skies will darken considerably during the eclipse.

In the UK, the moon will begin to pass in front of the Sun from around 8:40am and will take about 2 hours to complete its passage across the Sun. In London the maximum eclipse will be at 9.31am. This article in the Telegraph has a handy graphic showing a map of the UK with the percentages and times of maximum totality for your local area:

http://www.telegraph.co.uk/news/science/space/11434924/Solar-eclipse-will-plunge-Britain-into-morning-twilight.html

The next time the UK will experience a total eclipse will be in 2090, so make the most of any viewing opportunities!

Your local astronomy clubs will probably have handy hints on how to watch the eclipse safely and many are holding special meetings to watch the eclipse through specialist equipment. Remember: never look directly at the Sun :!:

If the weather is not cloudy I will be going to Alexander Palace to view the eclipse.
Hopefully take a few photographs
Don't forget the sun is dangerous and only view it through approved filters.

I am busy looking at filters for my new Canon DSLR as we speak! :D Which filter are you using?

They have temporarily sold out of BAADER solar eclipse observing glasses, but they will be back in stock this Friday and are only £2.99 - a great way to view the eclipse safely. Click the link below on Friday to order yours

I have a sheet of Baader AstroSolar Safety Film ND 5.0 which I have use to create lens filters. I also have a number of ND filters.
