I always wondered where they get all the antimatter to power the starships in Star Trek. Maybe they get it from the centre of the galaxy. New results from NASA’s INTEGRAL spacecraft, which tracks gamma ray emissions, may have explained the origin of the cloyd of antimatter that seems to be…

I love NASA’s Astronomy Picture of the Day, known to its friends as APOD. So to honour that Great website, which has been running for more than a decade, I here present my own personal top ten list of APODs. They may not be quite the same as anyone else…

I recently saw a Digg article which linked to a space.com page about the 10 Strangest Things in Space. All but 2 of the items were not pictures at all but computer simulations, or artists impressions. So here to correct this injustice to phenomena everywhere I present the REAL 10 Strangest…

Just the other day I was opining about how the internet needs to get in bed with science a bit more. Well lo and behold here is a fantastic example of just such a thing: Galaxy Zoo.

I saw the link on Chris Lintott’s blog and then later on Digg, but…

A while ago I posted about the Bullet Cluster, and an image which seems to reveal the dark matter within it. Now a new image from Hubble seems to do the same thing for the galaxy cluster CL0024+17.

Now I am personally rather sceptical about the validity of images such…

NASA’s Chandra observatory, in unison with ground-based optical telescopes, has relased details of a supernova from last September which is the brightest ever recorded. SN 2006gy exploded in galaxy NGC 1260 and was the brightest such event ever seen. NGC 1260 is 240 million light years away and the supernoa…

The Darwin Lecture for the National Astronomy Meeting 2007 was given by Dr. Reinhard Genzel. He spoke about the black hole which sits at the centre of the Milky Way, our own galaxy.

Early infrared astronomy showed very fast motions in the central mass of the galaxy. 20 years later…

The image above shows the Bullet Cluster. Also known as 1E 0657-56, this is a pair of clusters of galaxies some 3.4 billion light years away. As Jon Davies told us in yesterday’s Astrolunch meeting however: you should be careful about believing everything you see. This image is not a regular photograph…
