The Philae lander is SAFELY down on the comet, half a billion miles 28 light minutes from Earth. ( See Rosetta and the Comet) Yay for the European Space Agency – nobody’s ever done this before.
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.
In the past three years NASA’s Solar Dynamics Observatory has had virtually unbroken coverage of the sun’s rise toward solar maximum, the peak of solar activity in its regular 11-year cycle. This video shows the changes at two images a day. En los últimos tres años del Observatorio de Dinámica Solar de la NASA ha tenido una cobertura prácticamente ininterrumpida de subida del sol hacia el máximo solar, el pico…
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…
