The bright star seen below the galaxy and on the left half of the image is Altair, also one of the brightest stars in the night sky and located in the constellation Aquila. As it is also a relatively close star, only about 25 light-years away, with a relatively simple name, it frequently appears in modern science fiction, for example in Carl Sagan’s famous novel “Contact”, which was filmed in 1997 with Jodie Foster starring as a radio astronomer. Being a white star, it is the standard star astrophysicists use to define the colour scale. The bright star in the top-left side of the image is Vega, one of the brightest stars in the night sky and located in the small constellation Lyra. While the telescopes and the people working with them may ignore the constellations, the photographer managed to catch the Milky Way in such a way that it almost matches the shape of the mountain. Taken in May 2022 in Teide National Park in Tenerife, Spain, this image shows the arc of the Milky Way galaxy crossing the sky, accompanied by prominent constellations over the professional telescopes located on the mountains of that island.

The very bright object rising from behind the volcanoes of the Andes, creating spectacular shadows and crepuscular rays, is the Moon. There are also a few meteors blinking in some of the frames, one of them with a long-lasting and developing trail. We can also see the planets Jupiter and Saturn in a close conjunction, even finding themselves in the significant beam of Zodiacal light setting down below the horizon. Since this video was taken from the southern hemisphere, the Greek hero from the northern hemisphere seems to be performing a headstand. In some of the next frames, Orion, the great hunter, appears clearly with its bright stars and its characteristic asterism, the belt, composed of three aligned bright stars. Canopus is the second brightest star in the sky, while Rigil Kentaurus is the third brightest. The bright whitish star in the top of the image and to the right of the Galaxy is Canopus, one of the brightest stars in the night sky, located in the constellation Carina. It is important for navigation purposes because its longer axis indicates the direction of the celestial south pole. Just above, we can also see the small constellation Crux, visible from the northern tropical circles southwards. In the bottom of the image the bright stars Rigil Kentaurus and Hadar (also known as Alpha and Beta Centauri) are visible, both in the constellation Centaurus. Right in the first frame we can see our home galaxy, the Milky Way, as well as both the Large and Small Magellanic clouds, two satellite galaxies orbiting the Milky Way. Shot in December 2020, this time-lapse shows the sky from San Pedro de Atacama, Chile, in the southern hemisphere.

It usually has domes or dome-shaped roofs that open and move to allow the observation of a certain region of the sky. It has specialized instruments such as telescopes, CCD cameras with special filters, computer rooms, and tools to analyze images. An astronomical observatory is a place designed and built exclusively to facilitate the observation of the day or night sky.
