October 2010: Blobby

October 2010

In the show this time, Dr Anthony Rushton tells us about the EVN and microquasars, and Prof Anne Zabludoff talks about blobs. As always, Megan brings us the latest astronomical news and we hear what can be seen in the October night sky.

The News

In the news this month:

Interview with Dr Anthony Rushton

Dr Anthony Rushton (ESO) tells us about the EVN and his research studying microquasars.

Interview with Prof Anne Zabludoff

Prof Zabludoff works at the University of Arizona and speaks here on her research into Lyman alpha 'blobs' at high redshift. Ann Zabludoff's research focuses principally on the evolution of the baryonic and dark matter components of galaxies and larger-scale structures, analyzing the environments of strong gravitational lenses to provide new constraints on the expansion rate of the Universe, the dark energy, and the dark matter halo characteristics of galaxies.

The Night Sky

Northern Hemisphere

Ian Morison tells us what we can see in the northern hemisphere night sky during October 2010.

There is a very nice skyscape at this time of year. Fairly high up in the south-west is the group of constellations Cygnus the Swan, Lyra the Lyre and Aquila the Eagle. Their respective brightest stars, Deneb, Vega and Altair make up the Summer Triangle. Down to the left of Cygnus lies the constellation Delphinus. Over towards the east, and due south in the mid evening, is the square of Pegasus. Below the square of Pegasus is the head, or circlet, of one of the two fish that make up Pisces. To the lower left is Cetus the Whale and down to the right is Aquarius. Up to the right of Pegasus lies Perseus and up to its right is the contellation Cassiopeia. Between Perseus and Cassiopeia lies the double cluster.

Southern Hemisphere

John Field from the Carter Observatory in New Zealand tells us what can be seen in the southern night sky during October 2010.

Spring is a time of change for the southern night sky. The winter constellations Scorpius and Saggitarius are descending in the west. The summer constellations Orion and Ursa Major are rising in the east.

Odds and Ends

World Space Week is this month, from the 4th to the 10th of October. Check the website for details of events in over 55 countries.

The Cassini spacecraft has captured a rather strange picture of two of Saturn's moons.

Work has started on the construction of the new visitors' centre at Jodrell Bank. The ground breaking at the site was on the 20th of September and the centre is due to be completed in Summer 2011. The visitors' facilities at Jodrell Bank will be somewhat limited during the construction period so please check the website before visiting.

Ian Morison recommends the book "Turn Left at Orion" by Guy Consolmagno and Dan M. Davis.
