NASA's home page is at Theoretically you should be able to get to what you want from here but NASA has an enormous amount of data on the web and has many sites. If you don't find what you are looking for try their search engine.


Jodrell Bank Observatory is part of the University of Manchester's Department of Physics and Astronomy. Their web site lets you find out what goes on at JBO by taking an on-line guided tour of the observatory or read about the history of Jodrell Bank. You may also visit the Jodrell Bank Science Centre & Arboretum or simply learn about what's happening in the sky this month. Research at Jodrell Bank includes studies of stars, pulsars, galaxies, quasars, gravitational lenses, CMB and SETI. There is an archive of pictures and photographs. 

The Lowell Observatory has an extensive range of information and resources.

Bradford Robotic Observatory is a 46cm totally autonomous telescope located high on the moors in West Yorkshire. It decides when conditions are good enough to observe and then works through a schedule of tasks. Anyone on the Internet may register and ask the telescope to look at anything in the northern night sky. 

The European Space Agency is Europe’s gateway to space. Its mission is to shape the development of Europe’s space capability and ensure that investment in space continues to deliver benefits to the citizens of Europe.

Ask the Astronomer

There are various web sites that offer an "Ask the Astronomer" facility where you can browse the archive of past questions, but if you don't find what you need to know, you can submit your question for an answer later. Here is a list of a few of them:-

News, Events and Publications

Sky & Telescope, the magazine, hosts a web site. While not an online version of the magazine it covers news and events, what to see in the sky, product specs and reviews, advice on telescopes, etc. They also issue a newsletter which you can subcribe to. 

The Astronomer Online is the web site for The Astronomer magazine.

Astronomy Now is the website for the Astronomy Now magazine

Practical Astronomer is a new subscription only magazine focussing on astrophotography and visual observing.

Places of interest

The Royal Observatory, Greenwich, London, SE10 9NF, (tel 020 8858 4422) is part of the National Maritime Museum (tel 020 8312 6557) which is renowned for the sections on time. There is a planetarium, open daily to the public and for educational presentations. Opening times are 10am-5pm daily, (closed 24-26th December). There is a charge for admission. For further information see the Royal Observatory Greenwich

Les Granges - Astronomy B + B in the South of France. With an extensive arrangement of telescopes, training and advice available and facilities catering for astronomy or just a nice holiday.

Fieldview - Another Astronomical B + B in the heart of Norfolk. Great accommodation and 6 telescopes with free advice and training.

Image collections and Astrophotography

The Hubble Telescope pictures can be found at The Hubble Site which is operated by the Association of Universities for Research in Astronomy, Inc. (AURA), on behalf of NASA, under contract with the Goddard Space Flight Center. 

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

The Digitized Sky Survey, (DSS), comprises a set of all-sky photographic surveys in E, V, J, R, and N bands conducted with the Palomar and UK Schmidt telescopes. 

Students for the Exploration and Development of Space, (SEDS), has two catalogues from which we obtain the thumbnails for the Deep Sky News pages. The Messier Catalog and theInteractive NGC Catalog Online

The 2MASS Atlas Image Gallery at IPAC contains pictures from an all sky survey at 2 microns, (infrared). More details about the Two Micron All Sky Survey can be found on their home page

The Deep Near Infrared Survey of the Southern Sky, (DENIS), is a deep astronomical survey of the Southern Sky in two near-infrared bands (J at 1.25 µ and K at 2.16 µ) and one optical band (I at 0.8 µ) simultaneously, conducted by a European consortium. 

The Sloan Digital Sky Survey, (SDSS) at Apache Point Observatory will map in detail one-quarter of the entire sky, determining the positions and absolute brightnesses of more than 100 million celestial objects. It will also measure the distances to more than a million galaxies and quasars.

UK astro imaging forum is a site dedicated to all area's of astro imaging.

Atmospheric Optics - Light playing on water drops, dust or ice crystals in the atmosphere produces a host of visual spectacles - rainbows, halos, glories, coronas and many more. Some can be seen almost every day or so, some are once in a lifetime sights. Find out where to see them and how they form. Then seek and enjoy them outdoors.

Solar System

For information about the Solar system as a whole try DMOZ. This provides a categorised searchable index to Science and Astronomy subjects (and others). This is the Solar Systemsection.    Orrery: Solar System Simulator is a Java Applet simulating a working Solar System model with gravitation and motions and sizes of planets and moons to scale. It can demonstrate Lagrange points and solar system (in)stability.   John Walker, who wrote Home Planet has a similar but web based one at Solar System Live.   The Nine Planets is a multimedia tour and overview of the solar system by Bill Arnett.

Among the Solar Observatories with a web presence are The National Solar Observatory which is operated by the Association of Universities for Research in Astronomy (AURA) at Sacramento Peak, New Mexico and Kitt Peak, Arizona.   The Solar Group of the Institute for Astronomy, University of Hawaii at CEK Mees Solar Observatory, located on Haleakala, Maui, Hawaii. An archive of solar data can be found at The ARTHEMIS Solar Data Archive

Comets Orbit ephemeris can be found at JPL. Press the [Select Target Body] button and enter the Comet (or Asteroid) name under the Small Body section.   There is a good source ofresources for Asteroid observation at Lowell.

Artificial Satelites

Artificial Satelitte orbit predictions for various satellites (weather, communication, HAM, Iridium and the ISS) can be checked at They also have a FAQ page and can produce sky charts tailored for your location. If you do not know your Lat/Long you can look them up in their data base. Once these have been entered, book mark the index page and it will retain them for you. 

The Remote Imaging Group's web site caters for everyone interested in remote imaging from satellites. They have a membership of nearly 2,500 spread around the world.

Campaign for Dark Skies, (CfDS - A Joint Commission of the BAA and the IDA) is a society with the aim of reversing the trend of wasting energy by lighting up the sky to the annoyance of those of us trying to do astronomy. As they say, "The light from the rest of the Universe takes hundreds, thousands or millions of years to reach our eyes. What a pity to lose it on the last moment of its journey!".

Need Less Campaign - Animations and posters to raise awareness of light polution.

The Extrasolar Planets Encyclopaedia , original French site, US mirror site at Harvard. Jean Schneider CNRS, Paris Observatory maintains this site as a clearing house for all the latest news.

UKSEDS - Students for the exploration and development of space. Is an international organisation dedicated to raising awareness of space education and space related issues in society. is a scientific experiment that harnesses spare CPU cycles on hundreds of thousands of Internet-connected computers (PCs and servers) in the Search for Extraterrestrial Intelligence (SETI). You can participate by running a program that downloads and analyzes radio telescope data (collected in piggy back style while the Aricebo telescope is making normal observations). There's a small possibility that you could be the one to detect the faint murmur of a civilization beyond Earth.

BBC space website has lots of information from observing to how star die and current information.

BBC norfolk website has basic information for beginners. Projects and information for children. - edited by Mark Thompson

Sky Maps has a free detailed map of the sky for Northern or Southern Hemisphere with a list of objects observable with naked eye, binoculars and telescopes.

Last, but by no means least, there is even a page dedicated to Solar Sails. It is amazing what you can find on the web.
