Incredible Images of the Sun

Posted by michael on from the it's-the-yellow-thing.-outside. dept.

shelterit writes "A new swedish telescope facility in La Palma uses a new technology to remove the blurriness of the atmosphere to snap new and astonishingly sharp images of the sun. Want to have a closer look at the surface of it? Reminds me of paintings I did as a kid."

    While this new system works great for the visible spectrum of the Sun's output, you still want a space-based observatory to monitor the Sun's output in the other parts of the electromagnetic spectrum. That's why satellites like SOHO are still important.

    Took me awhile to find out how it works. In a nutshell: "The adaptive mirror actually changes shape 1000 times a second in order to adjust for the rapidly changing blurring of the image. Finally, we are using techniques to further sharpen the images after they have been captured by electronic cameras. In the best images the resolution is close to 0.1 arcseconds. This is a factor of 1200 better than 20/20 vision."

    Because Hubble is not designed to point at the sun. Thermally, Hubble was designed so that one side of the telescope is always pointed towards the sun. For thermally stability it must always remain that way. Are you going to personally replace Hubble's primary mirror when it cracks due to solar heating?
