Miscellaneous Links

Astronomy Picture of the Day (APOD): Each day a different image or photograph of our fascinating universe is featured, along with a brief explanation written by a professional astronomer.

Buying Your First Telescope – A guide to telescopes, eyepieces and accessories.: Note that this publication is sponsored by a telescope manufacturer and so refers to equipment from that manufacturer only. This link is provided for general information purposes only and does not constitute an endorsement or recommendation.

Heavens Above – Satellite sightings and more.: Given your geographic location, this web site provides information on sighting satellites (such as the International Space Station) and also the visibility of planets, comets and asteroids.

Hubble Space Telescope – News, images, videos and talks explaining the science.: The web site incorporates Hubble Heritage, the archive of imagery that contains aesthetically impactful and scientifically accurate colour images of our universe.

Mr Eclipse – Everything you could possibly want to know about eclipses.: A total eclipse of the Sun has been described as the most spectacular event in all of Nature, and eclipses of the Moon have a unique beauty all their own. Fred Espenak explains everything for everyone from novices to experts.

Space Weather – News and information about the Sun-Earth environment.: The latest news on asteroids, aurorae, cosmic rays, fireballs, geomagnetic storms, noctilucent clouds, solar activity... and the science behind 'space weather'.

Watch the 45-minute talk / PDF handout of the talk

Imaging a Quasar – Catching the ancient light that started its journey before the Earth existed.: Large telescopes have imaged quasars (galaxies) that are billions of light-years distant. Is it possible to capture an image of one of these very remote objects WITHOUT using a telescope?
