ESA: Yepun, one of the Unit Telescopes of ESO’s Very Large Telescope (VLT)

Yepun (UT4), one of the Unit Telescopes of ESO’s Very Large Telescope (VLT) stands beneath bright star trails appearing to circle the south celestial pole, lying in the southern constellation of Octans (The Octant). 

Many exposures were taken over time and combined to give the final appearance of circular tracks.

Four Unit Telescopes (UTs) make up the VLT at Paranal, Chile.

Each UT possesses a name in the language of the native Mapuche tribe.

The names of the UTs — Antu, Kueyen, Melipal, and Yepun — represent celestial objects: the sun, moon, the Southern Cross constellation and Venus, respectively.

ESA ESO's VLT Captures Milky Way in the Southern Sky

The Milky Way arches across this rare 360-degree panorama of the night sky above the Paranal platform, home of ESO’s Very Large Telescope (VLT).

The image was made from 37 individual frames with a total exposure time of about 30 minutes, taken in the early morning hours.

The Moon is just rising and the zodiacal light shines above it, while the Milky Way stretches across the sky opposite the observatory.
