Title: Scientific Picture of the Week

First Direct Detection of an Exoplanet

(https://www.pc-pals.com/smf/proxy.php?request=http%3A%2F%2Fi71.photobucket.com%2Falbums%2Fi126%2Fweirdspaceman%2Ffomalhaut-planet.jpg&hash=83b370b3af12b5849d7044e05b66069a5e83251d)

It pains me to say this in a way, since I’ve spent the last couple of years trying todo the same thing (but at radio wavelengths) but the first extrasolar planet (i.e. a planet orbiting around a star which is not the Sun) appears to have been directly detected. Oh and its not just one… there are a couple! The first (image above) was discovered using the Hubble Space Telescope imaging the star Fomalhaut which is located about 25 light years from Earth. For a number of years there has been evidence of a planet being present - due to the perturbations it caused on the ring of gas and dust that surround the star. The planet is believed to have a mass similar to that of Jupiter but is at an orbital radius much further away (about 4 times that of the distance between Neptune and Jupiter).

Oh Haley sends her commiserations and regards.  She reckons exoplanet research is the most difficult field in astronomy.

probably one of the hardest... which is why I also do the radio survey stuff... gotta keep myself broad - yes obivous joke there.

Now you need to write a definition of obivous, Sam. ;)
