An Evolutionary Diagram for Prestellar Cores

Yesterday saw my latest research paper posted on to the arXiv. It has been accepted for publication in Monthly Notices of the Royal Astronomical society. Here’s the abstract: We propose an evolutionary path for prestellar cores on the radius-mass diagram, which is analogous to stellar evolutionary paths on the Hertzsprung-Russell Diagram. Using James Clerk Maxwell […]


.Astronomy PenCasting Gallery

Pencasts are interactive Flash videos of handwritten notes and audio captured by the Pulse Livescribe smartpen. Jose Enrique Ruiz created this lovely gallery of pencasts during the .Astronomy Hack Day, as a way of explaining them to everyone. The pens cost about £100 and do some other amazing things too. A very clever idea and […]



ChromoTone is a wonderful way to explore the meaning of astronomy in wavelengths beyond the optical. Rather than apply colours to the different wavelengths of the EM spectrum, ChromoTone uses different notes, turning colour into musical sounds. What’s really great about ChromoTone is the blend of astronomy and music. The group that made this cool […]


I Am One (Saturnian) Year Old Today

Today, March 16th 2011, is my first Saturnian birthday. I shall go and have a low-density birthday cake. This great website, from the Exploratorium, lets you find out your ages and birthdays on all the planets (and Pluto!). It’s just over a year until my fiftieth Venusian birthday. Maybe I’ll have an actual party?


Astronomy Evening for Tal’s Good Feet

I have blogged before about the fundraising effort to get my nephew, Taliesin, a life-changing operation for cerebral palsy. you can read all about Tal’s Good Feet Fund on the website. I’ll be running an astronomy event in Witney on April 9th at 7pm. You can find it on Facebook or on the Tals’ Good […]

There are several women astronauts. The earliest footprints — 3.6 million years old — made by a member of the human family have been found in a volcanic ash flow in Tanzania by Mary Leakey. Trailblazing studies of the behavior of primates in the wild have been performed by dozens of young women, each spending years with a different primate species. Jane Goodall’s studies of the chimpanzee are the best known of the investigations which illuminate human origins. The undersea depth record is held by Sylvia Earle. The solar wind was first measured in situ by Marcia Neugebauer, using the Mariner 2 spacecraft. The first active volcanos beyond the Earth were discovered on the Jovian moon Io by Linda Morabito, using the Voyager 1 spacecraft. These examples of modern exploration and discovery could be multiplied a hundredfold. They are of true historical significance.
