The Alma radio telescope took this amazing picture of planets forming around the sun-like star, HL Tau. This is a baby star, less than a million years old, which is 450 light years from Earth in the constellation Taurus. And the disc of dust and gas around the star is already forming planets and asteroids – that’s what makes the dark rings in the brighter dust. It’s the first…
This amazing picture of stars being born inside a nebula was taken by Daniel Lopez using Grantecan. Near the centre of the picture is a dark red spot – that’s the new star which shines mostly in the infrared. The butterfly shape is a large disk of dust and gas orbiting the star. The gas near the star shines because it is ionized (like the inside of a flourescent…
Light is made of electromagnetic waves, and our eyes see different wavelengths as different colours. But our eyes can’t see most wavelengths at all, which is a pity – think how different the human body looks when you see it in x-rays. This is the sun at 13 different wavelengths.
There’s a really simple reason why the Royal Greenwich Observatory moved their telescopes here. It’s one of the three best places in the world for astronomy. The observatory was founded in 1675 by Charles II of England – hence the “royal” for £520 (£20 over budget!). It was the first purpose-built scientific research facility in Britain. At the time, Greenwich was a great place to build it – away…
The MAGIC telescope has the biggest telescope mirrors in the world. I’ve always wanted to get up the green tower to prime focus, where the light is focused onto the camera. I finally got up there in July. Even better, my friend Carolin Liefke (from the Max Plank Institute) had a camera with a fisheye lens and the skill to make good use of it. You can read more…
Tuesday night is the best meteor shower of the year, the Perseids. Of course it should be visible all over the planet, but La Palma’s astronomical viewpoints will probably be a particularly good place to see shooting stars. Unfortunately the full moon will spoil the show quite a bit. Cielos La Palma will be in La Polvacera basketball court from 9 pm – midnight with telescopes. Toño will also…
