Die Yepun-teleskoop van die Paranal-sterrewag teiken die galaktiese middelpunt met laserlig.
摘要
[編輯]描述ESO-VLT-Laser-phot-33a-07.jpg |
Afrikaans: 'n Beeld van die naghemel oor die Paranal-sterrewag op 21 Julie 2007, geneem deur ESO-sterrekundige Yuri Beletsky. 'n Wye gordel van sterre en stofwolke wat 'n hoek van 100 grade oorspan, is hier te siene. Dit is naamlik die Melkweg, die sterrestelsel wat ons aardse woning bevat. Onder die Melkweg is twee helder voorwerpe sigbaar; die helderste is die planeet Jupiter en die tweede die ster Antares. Koepels van drie uit die vier 8,2 meter-teleskope waaruit die ESO se BGT bestaan is hier sigbaar, met Yepun (eenheidsteleskoop 4) wat die galaktiese middelpunt met laserlig teiken. Ook sigbaar is drie van die 1,8-meter bystandsteleskope wat vir interferometrie aangewend word. Diodes binne die koepels veroorsaak die kort ligstrepies op die foto. Die beligtingstyd was 5 minute en omdat die klokmotor die sterreagtergrond gevolg het, staan die koepels net onduidelik uit.
English: Image of the night sky above Paranal, Chile on 21 July 2007, taken by ESO astronomer Yuri Beletsky. A wide band of stars and dust clouds, spanning more than 100 degrees on the sky, is seen. This is the Milky Way, the galaxy to which we belong. At the centre of the image, two bright objects are visible. The brightest is the planet Jupiter, while the other is the star Antares. Three of the four 8.2-m telescopes forming ESO's VLT are seen, with a laser beaming out from Yepun, Unit Telescope number 4. The laser points directly at the Galactic Centre. Also visible are three of the 1.8-m Auxiliary Telescopes used for interferometry. They show small light beams which are diodes located on the domes. The exposure time is 5 minutes and because the tracking was made on the stars, the telescopes are slightly blurred. |
