This page describes an image ESO's Very Large Telescope (VLT) at Paranal Observatory with a lunar halo
Image caption:
The Very Large Telescope on Cerro Paranal in Chile has four reflecting telescopes each with a primary mirror 8.2m across. In this image one dome is open and firing laser beams into the sky. These lasers create artificial stars in the sky that can be used to adjust the telescope optics to remove the blurring effect of the Earth's atmosphere. This process is known as adaptive optics.
In the sky the Moon is surrounded by a bright halo. This is caused by light from the moon reflecting inside ice crystals in the Earth's atmosphere.

Image caption: Il Very Large Telescope di Cerro Paranal, in Cile, dispone di quattro telescopi riflettenti, ciascuno con uno specchio primario di 8,2 metri di diametro. In questa immagine una cupola è aperta e spara raggi laser nel cielo. Questi laser creano in cielo stelle artificiali, che possono essere utilizzate per regolare l'ottica del telescopio così da eliminare l'effetto di sfocatura dell'atmosfera terrestre. Questo processo è noto come ottica adattiva.
Nel cielo, la Luna è circondata da un alone luminoso. Questo fenomeno è provocato dalla luce della Luna, che si riflette all'interno dei cristalli di ghiaccio dell'atmosfera terrestre.

Image caption: 位于智利帕瑞纳山的甚大望远镜由四台反射望远镜组成，每台望远镜的主镜直径为8.2米。在这张照片中图中，其中一个穹顶打开着，并向天空发射激光束。这些激光在天空中创造出“人造星”，用于调整望远镜的光学系统，从而消除地球大气层引起的模糊效应，这一过程被称为自适应光学。
在天空中，月亮被明亮的光晕围绕。该现象是由月光在地球大气中的冰晶内反射而形成的。
