How can a universe that seems so cold, dark, and sterile become a place where life can flourish? This is one of the questions that the astronomer Dr Jennifer Wiseman asked in her seminar at the Faraday Institute last month. In her talk, part of which I have summarised here in my own words, she explained why the cosmos can be seen as a very fruitful place – and why this idea is compatible with her own sense of  purpose for the world.

Jennifer grew up on a farm in Arkansas, where she came to know the stars in a way that those of us who have lived in light-polluted cities all our lives could never appreciate. She went Continue reading

Life in a Bountiful Universe

The astronomer Dr Jennifer Wiseman visited Cambridge recently to speak about her work on ‘exoplanet’ discovery. Exoplanets are planets in solar systems other than our own, and until 1989 they were the stuff of science fiction. Now we know there definitely are other planets in the universe, some of which may be like Earth. The discovery of life on other planets – perhaps single celled organisms – in the next few decades is a real possibility.

Our universe is active and fruitful. We live in an abundant universe, and can celebrate that with new knowledge. The changes made to the Hubble telescope in 2009 have brought us beautiful new pictures that show the universe in greater depth than ever before. This one of the Omega Centauri star cluster shows a startling variety of stars.

The universe is beautiful, and the range of telescopes that astronomers use are like a symphony orchestra, with many different instruments contributing to our knowledge of the universe. Continue reading
