Ibland j\u00e4klas naturen \u00e4ven med diverse puttifnasker.

The Sun rises behind Cerro Armazones in this image from 2016, with the sunlight marking the flat silhouette of the mountain top and Venus witnessing the beginning of a new day from just above the mountain itself. The picture is a stunning example of crepuscular rays, occurring when objects such as clouds or mountains block part of the incoming sunlight, a phenomenon typical at sunrise and sunset when the Sun is low on the horizon or below it. The top of Cerro Armazones was flattened to become home to the Extremely Large Telescope (ELT), ESO\u2019s next flagship observatory currently under construction. With its main mirror 39 metres in diameter, the ELT will be the world\u2019s largest eye on the Universe, able to collect 100 000 000 times more light than the human eye. It will help astronomers find new planets where life may have developed, shed light on the nature of stars and black holes and unveil some of the most intimate secrets of the Universe. The picture was taken from Paranal, where ESO operates observatories such as the Very Large Telescope (VLT), the Visible and Infrared Survey Telescope for Astronomy (VISTA) and the VLT Survey Telescope.<\/em><\/figcaption><\/figure>\n\n\n\n

Br\u00f6texten i ESO-messet<\/a> lyder s\u00e5 h\u00e4r: “Due to the war in Ukraine, to support our colleagues in the scientific community and their families, ESO is announcing a Special Visitor Programme for Scientists working in the country to visit one of the ESO premises (Garching, Germany or Vitacura, Chile) to conduct scientific or technical projects. Grants will be provided in support of these scientific visits, and travel and accommodation will be covered for the full duration of the project. More information can be found on the\u00a0ESO science pages<\/a>.\u00a0<\/p>\n\n\n\n

All ESO Member States have condemned the military invasion of Ukraine ordered by the Russian leadership, which blatantly violates the most fundamental human rights and is entirely incompatible with our values at ESO. ESO does not have and does not intend to have any official relationship with institutions and companies from Russia and Belarus under the current circumstances.”<\/p>\n\n\n\n

Naturen \u00e4r ibland elak (men alltid r\u00e4ttvis). Exempel: Det finns p\u00e5 n\u00e4tet en rad bilder p\u00e5 regnb\u00e5gar \u00f6ver Kreml och R\u00f6da torget. Ha!<\/p>\n\n\n\n
