I was lucky enough to be able to join the belated Solstice dinner held by the Association of Starlight Guides on Tenerife. It was great to meet so many of my collegues, but best of all, the dinner as held in the Teide Observatory. I’ve been wanting to have a look inside for at least 5 years. It meant an early start. I needed the car to move around,…
The Roque de Los Muchachos is a spectacular place to watch the sunset. For one thing, you’re usually above the clouds (which is one reason the observatory is there.) In fact, sometimes the clouds are so much lower than the Roque that the sun sets well below you. This means that your shadow on a wall is taller than you, and the shadows of your legs go on forever….
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…
This was photographed from a plane flying at 13,300 m going 800 km/h, 960 km southeast of Bermuda. In order to get the eclipse to one side of the plane, they flew across the path of totality, rather than along it. This required split-second timing, since the shadow on the moon moves across the Earth’s surface at 12,800 km/h. The photographer, Ben Cooper, isn’t sure whether this is totality…
On November 3rd 2013 there will be a partial solar eclipse. Well, it’s a total eclipse in some places and an annual eclipse in others, ubt fromteh Canary Islands we get a partial eclipse. 40% of the sun will be covered by the moon at 12:15 pm. From the UK there won’t be anything to see. Do NOT look directly at the sun. You might go blind. There are two…
