A big Lidl telescope in Belfast

Alan Fitzsimmons and his telescope

Not so Lidl: Alan Fitzsimmons and his bargain telescope.

By Hamish Johnston

There is an old joke in the UK about going to the discount supermarket Lidl for a pint of milk and coming home with a new set of power tools or ski-wear for the entire family. That’s because the retailer is famous for its seemingly random special offers. One week it could be car accessories and the following week the same shelves could be stocked with pyjamas or camping gear.

But Alan Fitzsimmons of Queen’s University Belfast deserves an award for best physics-related Lidl bargain with this huge telescope that he bought at the supermarket. It makes perfect sense to me – both Lidl and the telescope’s maker Bresser are German companies and, of course, Germany is famous for its optics.

New York dims its lights for birds

It’s been a great week for birds – or at least those flying over the state of New York – after state governor Andrew Cuomo pledged to create safer migration routes for our feathered friends. All state buildings will now have to comply with a national US initiative that seeks to curb levels of light pollution, which can disorient birds and lead to huge numbers of avian deaths by “fatal light attraction”.

Many species of bird rely on the light from star constellations to help them navigate during spring and autumn migrations. Unfortunately, artificial light sources can throw the animals off course, and light reflected from glass can cause the birds to smack into windows, walls, floodlights and other hard surfaces. It is estimated that as many as a billion birds succumb to this cruel end each year in the US alone, according to the US Department of Agriculture.
