If you don’t know how to fix it, please stop breaking it. You grown ups say you love us. Please, take action. And for me,it is absolutely my responsibility to do whatever it takes to protect my child. When the haze gets serious, there is at least one thing we can do. That is to protect yourself and your loved ones…
Name any event in history and you will find a star out there whose light gives you a glimpse of something happening during the year of that event. Provided you are not a very young child, somewhere up in the night sky you can find your personal birth star. Its light is a thermonuclear glow that heralds the year of…
When we spend time in the wilderness, it can be tempting to focus our awareness on "doing" something: taking pictures; getting a certain amount of physical exercise; traveling from point A to point B; naming all the species of birds we encounter. While nature photography is a lovely craft, and we need to exercise for…
Every 12 years Jupiter returns to the same position in the sky; every 370 days it disappears in the fire of the Sun in the evening to the west, 30 days later it reappears in the morning to the east...
We find it hard to picture to ourselves the state of mind of a man of older days who firmly believed that the Earth was the centre of the Universe, and that all the heavenly bodies revolved around it. He could feel beneath his feet the writhings of the damned amid the flames; very likely he had seen with his own eyes…
Some people want to put warning stickers on biology textbooks, saying that the theory of evolution is just one of many theories, take it or leave it. Now, religion long predates science; it'll be here forever. That's not the issue. The problem comes when religion enters the science classroom. There's no tradition of…
Here we go again, one of the epic documents of our time, the Hubble Ultra Deep Field (UDF) photograph, the deepest look into space ever. A random part of the sky, so small it could be covered by a pinhead held at arm's length. A part of the sky -- as NASA says -- that you'd see looking through an eight-foot-long soda…
Imagine that we could see the night with eyes the size and sensitivity of the Hubble Space Telescope. How paltry then would seem our terrestrial gods, our shabby deities with human faces. How ridiculous our intolerances, how hollow our claims to have privileged access to the mind of God.
This method of viewing the galaxies (‘to continue the simile I have borrowed from the vegetable kingdom’) presented the entire universe in a new kind of light, with the most radical implications. ‘The heavens are now seen to resemble a luxuriant garden which contains the greatest variety of productions, in different…
It is possible to measure how far away from us each galaxy is. How? How, for that matter, do we know how far away anything in the universe is? For nearby stars the best method uses something called 'parallax'. Hold your finger up in front of your face and look at it with your left eye closed. Now open your left eye…
In all the history of mankind, there will be only one generation that will be first to explore the Solar System, one generation for which, in childhood, the planets are distant and indistinct discs moving through the night sky, and for which, in old age, the planets are places, diverse new worlds in the course of…
After an evening of talk, perhaps about the fringes of knowledge, or some new possibility of climbing inside the minds and senses of animals, we would go out on the lawn, where we took turns at an amusing little astronomical rite. We searched until we found, with or without glasses, the faint, heavenly spot of…
