A ring of dark matter has been found around a cluster of galaxies, as seen through the Hubble space telescope.
New light on dark galaxies. More on the still mysterious dark matter in the universe.
The history of astronomy must go back even further in time. Early humans in South-East Asia, of at least two different species, succeeded in travelling across open sea to islands in what is now Indonesia, and further to Australia. As much as a million years ago. Even in an ice-age, open seas wide enough to form a barrier to plants and animals divided islands like Flores from its neighbours, and the Australian continent from South-East Asia. These early voyagers would have had the technology to make sea-worthy boats - or they would have been eaten by sharks or crocodiles and never made it. And they must have had some way of finding their route since voyages were made and new settlements have been found since then. I hope very soon to go down to southern parts to find out more and fill in this earliest part of the history of astronomy and navigation.
The clock is being renovated again, and hopefully more will be discovered about its manufacture and the clock tower. Meanwhile you can read the full history up to now, the author of the official guides to the astronomical clock at Hampton Court Palace, this book contains the full information on the history of this famous clock much of which was not published in the official guide books. Including all those involved in the design, construction and maintenance, and the discovery of the hidden Tudor loo.

Ulughbek and his Observatory in Samarkand. ISBN: 978-1-871443-18-9
by Heather Hobden.
Ulughbek was assassinated by religious extremists who razed his observatory to the ground. But his work on astronomy survived. As Ulughbek said in words that incensed the religious fanatics:"Religion disperses like a fog, kingdoms perish, but the works of scholars remain for an eternity."
The booklet was originally published as an article in Astronomy Now, August 1988. A short article for space.com edited by Gian Trotter for the American market, was published 17th October 2001, and was much quoted and referenced.
