Each day a different image or photograph of our fascinating universe is featured, along with a brief explanation written by a professional astronomer. The telescope contains no windows or lenses because focusing bright sunlight would overheat them. Visible in the background of this sunrise photo are the Moon and Venus . The telescopes are used in many research projects including determining the Sun's structure , researching the cause of the solar corona , monitoring Sun-spots and solar flares , and observing bright planets and comets near the Sun .
