Free space images from the web

I just looked at a few sites providing space related images for download. All images – except the logo’s from these three sites are freely useable for non-commercial purposes, including personal web sites – of course with a clear attribution of the source.

The three sites I looked up here are

NASA (of course)for general space travel and some astronomical images.

The Spitzer Space Telescope for images taken in infrared

and of course The Hubble Space Telescope with some of the most stunning astronomical images made

If you like images, maybe using them part of your web pages these are three very good sources.

Do not forget that many observatories and universities have images available. These include very old images from the classical telescopes in the world. I believe there is a project to scan all those ancient images before they are lost forever due to the deterioration pf the photographic material.

The old images *could* become important  for detecting transient events or variable phenomena, like recurring nova outbursts, so we can not afford to lose these images.

Planets detected around Epsilon Eridani

This is exciting for me as  a science fiction fan and as someone interested in space science in general.

Epsilon Eridani is a star a bit smaller than our own Sun – and quite young – only 800 million years old, located about 10.5 light years away.  Recently the Spitzer Telescope has detected a double asteroid belt around the star. The inner belt is located at a distance similar to the asteroid belt in our own solar system. Furthermore what looks like a cometary ring similar to the Kuyper Belt and indications of a planet at a distance similar to Jupiter’s. The Epsilon Eridani system looks more and more like our own solar system.

For more information take a look at these websites :

In the 1960’s I remember the scientific programs on the radio talking about SETI (Search for Extra Terrestrial Intelligence) and mentioning this star as a likely candidate. At the time the young age of the system was not known, but it gave rise to the use of many science fiction writers using it as a home for intelligence.

In “Star Trek” the Mr. Spock’s home world Vulcan is located in the Epsilon Eridani system. and in “Babylon 5” the space station is in orbit around a planet in the same system.

Of course the star is featured in many other science fiction stories, too many to mention here.

Interesting stuff…

David Tennant leaves Doctor Who

I just got the news that David Tennant is leaving Doctor Who at the end of 2009, see the news from the BBC. Unfortunately, if you are outside the UK the interview cannot be seen from the BBC website. Possibly it is out there on U-Tube, but I have not investigated.

We will still see Tennant in the Christmas Special this year and in 4 specials in 2009. Interesting enough the title of the Christmas special will be “The Next Doctor”. Could this be an indication of things to come ?

2010 will see a new showrunner, Steven Moffatt, along with the 11th (or is it 12th after the “funny” regeneration last season?) Doctor.

It will be interesting to see who will be cast as the 11th Doctor. Your guess is as good as mine. The rumour mill has probably already started.

I will have to say that I really liked Tennant as The Doctor. This autumn/fall he has been playing Hamlet with Patrick Stewart in the UK. Stewart has said that he is interested in being in Doctor Who, it could be interesting to see him as a villain for a change. Could he become the 11th Doctor ? Possibly, but I doubt it. It could be interesting, though.
