Un antiguo compañero de trabajo, Bruno Altieri, ha descubierto en el centro de la galaxia NGC 6505 (dcha.), con los datos de Euclid, un "anillo de Einstein", un caso particular de imagen de lente gravitacional: el anillo de Altieri (izda.).

The ring of light surrounding the centre of the galaxy NGC 6505, captured by ESA’s Euclid telescope, is a stunning example of an Einstein ring. NGC 6505 is acting as a gravitational lens, bending light from a galaxy far behind it. The almost perfect alignment of NGC 6505 and the background galaxy has bent and magnified the light from the background galaxy into a spectacular ring. This rare phenomenon was first theorised to exist by Einstein in his general theory of relativity. This wide field shows the extended stellar halo of NGC 6505 and showcases the Einstein ring, surrounded by colourful foreground stars and background galaxies. A close-up view of the centre of the NGC 6505 galaxy, with the bright Einstein ring around its nucleus, captured by ESA’s Euclid space telescope. The Einstein ring is formed by gravitational lensing, with the mass of galaxy NGC 6505 bending and magnifying the light from a more distant galaxy into a ring. NGC 6505 is a well-known galaxy only around 590 million light-years from Earth, and Euclid’s discovery of a spectacular Einstein ring here was unexpected.

Willem Arondéus (1894 – 1943) was a Dutch artist and author who joined the Dutch anti-Nazi resistance movement during World War II.
He was a gay badass who fought nazis to death.
Before his execution, his last words were: "Tell people that homosexuals are not cowards."
A black and white, full body portrait of a white man in his thirties, sitting at home or other interior setting, looking back at the viewer with kind but also sad eyes. An art nouveau style post stam. It reads on top: KOOPT ZOMER POSTZEGELS 1938 Then there is an illustration of a flowered tree with ripe fruit too, looks like pear or apple. I don't know what means, but on the side it reads: WAARVAN DE VRUCHTEN BESTEMD ZIJN VOOR CULTURELE EN SOCIALE DOELEINDEN. The poster is signed W. Arondéus.
