V838 Monocerotis
Awesome! Plain and simply awesome.
V838 Monocerotis
From the Hubble website. Here’s the description of the image:
“Starry Night”, Vincent van Gogh‘s famous painting, is renowned for its bold whorls of light sweeping across a raging night sky. Although this image of the heavens came only from the artist’s restless imagination, a new picture from the NASA/ESA Hubble Space Telescope bears remarkable similarities to the van Gogh work, complete with never-before-seen spirals of dust swirling across trillions of kilometres of interstellar space.
This image, obtained with the Advanced Camera for Surveys on February 8, 2004, is Hubble’s latest view of an expanding halo of light around a distant star, named V838 Monocerotis (V838 Mon).
The illumination of interstellar dust comes from the red supergiant star at the middle of the image, which gave off a flashbulb-like pulse of light two years ago. V838 Mon is located about 20,000 light-years away from Earth in the direction of the constellation Monoceros, placing the star at the outer edge of our Milky Way galaxy.

Here are my thoughts.
A single light-year is approximately 6 trillion miles, or 9,460,730,472,580.8 kms for the metric brigade! Thus 20,000 light-years is 120,000 trillion miles, or 120,000,000,000,000,000 miles.
It is beyond imagination – yet it is real!
It humbles one beyond measure that in this short lifetime on mine, science has reached out so far. And then one looks more closely to home and remains appalled that we have learnt so little about living in peace and with integrity on this funny third rock from the Sun.
The ultimate paradox!

Happy Birthday, Hubble!
The Hubble Space Telescope (HST) has been in space for 20 years!
This week, twenty years ago, the HST was launched into orbit. There’s much online if you want to read about it both on WikiPedia and on the Hubble web site so this post is going to offer just two items.
A beautiful picture

And an interesting audio slideshow tribute from the BBC – click here, introduced thus:
Take a look at some of the sights it has seen in that time with Professor Alec Boksenberg from the Institute of Astronomy in Cambridge – who was on the European team that helped build Hubble.
