Astrobiology

Studying the origins of life and looking for life in the universe is complex, involving biologists, chemists who study molecules in interstellar clouds and those who search for extrasolar planets.

Chemical Cosmos - book review star
"The Chemical Cosmos: A Guided Tour" is an astronomy book about chemistry - or perhaps a chemistry book about astronomy. It´s an engrossing guided tour that will take you from the baby Universe through the first stars, the formation of solar systems and to our search for the origins of life.

Do Red Dwarfs Live Forever star
Looking up at a clear, dark sky, you can see thousands of stars. Yet without binoculars or a telescope, the most common type of star is invisible. These are the small, cool red dwarfs that fill the sky and live practically forever.

Exotic Exoplanets Tour star
We're used to a tidy Solar System. But there are some pretty strange planets orbiting stars far, far away. On one it doesn't rain water, it rains rock. Another has the density of cork. One has a double sun. And what would you do with a diamond the size of a planet?

Extrasolar Planets Encyclopaedia star[offsite link]
This is an interactive catalog of the planets. It tells you when and how they were discovered and information about them. You can also find out what groups are involved in the searches and the latest news.

George´s Cosmic Treasure Hunt - book review star
George is sad. The family next door are moving away and things will be so dull without them. Or maybe not! Why is the new Martian rover acting so strangely? Has the search for life met an alien threat to Earth? Lucy and Stephen Hawking take George and the reader on a cosmic adventure.

It´s Alive - book review star
The Universe Verse is back. Book 1 was the Big Bang Theory in verse and drawings. Now stars and planets have formed, but something new is happening: Life. Book 2 is about evolution by natural selection. In its cheerful verse and lovely color drawings, it´s also a love poem to our beautiful Earth.

Lacaille´s skies – Arts star
Much of the southern sky wasn´t visible to the ancient Mediterranean civilizations. Instead of representing the ancient myths, the constellations were invented long afterwards by European explorers and astronomers. Some of Abbe Lacaille´s inventions are tributes to the arts.

Red Dwarfs - Ten Facts for Kids star
If you go outside on a clear dark night, you might see a few thousand stars. But without a telescope, not a single one will be the most common type of star in the Universe. You won´t see red dwarfs, the stars that will still be shining in the far distant future when all the others have died.

Searching for Extrasolar Planets star
Only a few dozen planets orbiting stars outside the Solar System were directly imaged. But as of October 2013 astronomers had discovered over a thousand of them. How do they find what they can't see?

The New Martians – book review star
Fast forward to 2035. The first manned Mars expedition is going home, and things have started to go wrong. The psychological pressures of being a small group spending a few years together in a hostile environment are getting to them. They´re also unaware that they´ve acquired a hitchhiker.

Top Astronomy Stories 2012 star
What were the big astronomy stories of the year 2012? Here is my choice of the top ten plus a non-story. What do you think?

Top Ten Astronomy Stories of 2013 star
What were the big astronomy events of 2013? Here are my top ten choices and they include a big bang over Russia, a Moon goddess and Jade Rabbit, a telescope in the high Andean desert to look for the first galaxies and the launch one of the most ambitious space missions ever.

Virgo the Maiden star
Virgo is one of the constellations of the zodiac, and its stars have been linked to agricultural goddesses for thousands of years. This area of sky contains thousands of galaxies, dozens of known extrasolar planets, and was where the first quasar was discovered.

What Is Astrobiology star
Do you wonder if there's life elsewhere in the universe? The universe is a big place, so it seems likely that there is. See how astrobiologists are helping to plan the search.
