Cosmic Diary Logo

Meet the astronomers. See where they work. Know what they know.


The Project:

The Cosmic Diary is not just about astronomy. It's more about what it is like to be an astronomer.

The Cosmic Diary aims to put a human face on astronomy: professional scientists will blog in text and images about their lives, families, friends, hobbies and interests, as well as their work, their latest research findings and the challenges that face them. The bloggers represent a vibrant cross-section of female and male working astronomers from around the world, coming from five different continents. Outside the observatories, labs and offices they are musicians, mothers, photographers, athletes, amateur astronomers. At work, they are managers, observers, graduate students, grant proposers, instrument builders and data analysts.

Throughout this project, all the bloggers will be asked to explain one particular aspect of their work to the public. In a true exercise of science communication, these scientists will use easy-to-understand language to translate the nuts and bolts of their scientific research into a popular science article. This will be their challenge.

Binary stars in Brno – the BinKey conference

During the second week of June, I travelled from Prague to the Czech Republic’s second city of Brno, some 200 km to the south-east of Prague in the province of Moravia. The purpose was to participate in a conference named BinKey – on binary stars as a key to the comprehension of the universe. The meeting attracted over 150 participants from many parts of the world, but predominantly from eastern and central Europe, countries which 20 years ago were behind the Iron Curtain, but now transformed into thriving free economies. I met no-one from these eastern European countries who didn’t agree that life, and especially scientific life, was not now much better than it was two decades earlier, in spite of the many current economic problems that we all face.

Incredible nu Octantis: a close binary with a possible planet?

If you are interested in extrasolar planets, then you should read this. The discovery has been made of what looks like a Jupiter-mass planet orbiting a red giant in a close binary, nu Octantis, in an orbit which should, by the normal rules of three-body dynamics, be unstable. The new observations are likely to cause a complete rethink about the stability of planetary orbits in close binaries. Or, if someone can show that this is not a planet, then the observations of nu Octantis could cast doubt on other observations of hitherto claimed planets detected by the Doppler technique.
