Whirlpool Galaxy
Whirlpool Galaxy
<P> This image of the Whirlpool Galaxy, taken in January 2005 by the Hubble Space Telescope, illustrates a spiral galaxy's grand design, from its curving spiral arms, where young stars reside, to its yellowish central core, a home of older stars. The galaxy is nicknamed the Whirlpool because of its swirling structure. </P> <P> Located 31 million light-years away in the constellation Canes Venatici (the Hunting Dogs), the Whirlpool's beautiful face-on view and closeness to Earth allow astronomers to study a classic spiral galaxy's structure and star-forming processes. </P> <P> Text:<EM> NASA, ESA, S.

Women naturalists
Women naturalists
In 19th century Ireland there were many women naturalists. They included Ellen Hutchins (1785-1815) an internationally recognised expert on lichens and non-flowering plants, despite suffering ill-health and dying young. Anne Ball (1808-72) specialised in marine plants, while her sister Mary (1812-98) concentrated on insects and was the first to report stridulation in water bugs. Maude Delap's (1866-1953) research shed light on the complex life cycle of jellyfish. Cynthia Longfield (1896-1991) was an international expert on dragonflies. <EM>Image: Yellow-winged Darter by André Karwath (sourced from <A HREF="http://en.wikipedia.org/wiki/Image:Sympetrum_flaveolum_-_side_%28aka%29.jpg">Wikipedia</A> under the <A HREF="http://creativecommons.org/licenses/by-sa/2.5/">Creative Commons Attribution ShareAlike 2.5</A> license)</EM> </P>

The Parsons Family
The Parsons Family
<P> The Parsons were an inventive and enterprising family. William's wife, Mary Field, was a noted early photographer. Their son Laurence, fourth Earl of Rosse, inherited his father's love of astronomy and produced the first accurate measurements of the moon's temperature. </P> <P> Another son, Sir Charles, invented the steam turbine which revolutionised marine transport and naval warfare and made a cheap and plentiful electricity possible. His turbine design is still used in electricity generating stations. </P> <P> Pictured above is the restored Birr Leviathon, built by the Parsons and once the world's largest telescope. </P>

Royal Irish Academy
Royal Irish Academy
One of the first actions of the RIA was to spend £30 on barometers and thermometers for a network of weather stations around the country. The academy quickly established a reputation and its rollcall of members included many of the great names of the time, including Richard Lovell Edgeworth, Richard Kirwan (pictured) and later William Rowan Hamilton. Scientific projects it organised over the years included dredging expeditions to Rockall and bio-geographical surveys of Clare Island.
