The material presented in this section is part of the POP 123 project, driven by the Foundation Descubre (Andalusian institution for the outreach of the scientific knowledge). This project aims at letting the general public know about the astronomical data acquisition, ranging from the instrumentati on itself to the staff responsible for the gathering of raw data. This way, the general public can learn the basic principles of imaging in astronomy, beyond the communication of astronomical information at a professional level from highly reduced and analysed data.
For this purpose, this project makes use of a professional telescope at the Calar Alto Observatory (CAHA). The observatory has allocated to this project 60 observing nights per year using the 1.23m Zeiss Telescope to obtain images of both, scientific and aesthetic value.
DESCUBRE gives some of this observing time to the Documentary School of Astrophotography (DSA) lead by the astro-photographer Vicent Peris. Every image produced under this project is jointly owned by CAHA, DESCUBRE, and DSA, with the collaboration of the Astronomical Observatory of the University of Valencia (OAUV). Despite the youth of this project, it has already been awarded with the “Astronomy Picture of the Day” (NASA) by the fourth time.
The spiral galaxy NGC 7331, in Pegasus, can be seen with small telescopes under dark skies as a faint fuzzy spot. It is an island universe similar to our own Galaxy (or maybe somewhat larger) and placed at a distance of 50 million light-years. NGC 7331 was discovered by Wilhelm Herschel […]
The Andromeda galaxy illustrates the typical phenomena that occur in a normal spiral galaxy, perhaps presenting a similar scenario as if we were to look at our own Galaxy from far away… The Andromeda galaxy is, under normal conditions, the farthest object the human eye can see without optical aid. […]
The Spanish poet José Hierro, when presenting his book Cuaderno de Nueva York (“New York Notebook”), said that any major poet has to write about both New York and spring, at least once in a lifetime. The same could be said about M51, the Whirlpool Galaxy, in the context of astronomical imaging. Every relevant […]
Messier 74 appears in this image as the perfect archetype of a great design, face-on spiral galaxy, composed by a bright central core surrounded by faint and diffuse spiral arms. Spiral galaxies have flat shapes similar to dishes, causing a varying appearance depending on their inclination with respect to our […]
Stars similar to the Sun end their lives as white dwarfs. But, before becoming those dense stellar corpses, they expel their outer gaseous layers and they ornate the sky for some thousands of years with the most beautiful objects in the universe: planetary nebulae. M97, better known as Owl Nebula, belongs […]
The diversity of colours, shapes, and sizes of planetary nebulae make them fascinating objects. In this photo release Calar Alto presents a rather unique view combining both optical and near-infrared data of the Ring Nebula (M57). Planetary nebulae are sometimes called “cosmic butterflies”. In fact, their beauty and variety deserve the comparison. […]
In the deep space there are not only stars, but galaxies like ours contain nebulae: diffuse matter made up of gas and dust. These nebulae display a variety of shapes and colors that reflect the diversity of processes that take place when nearby star light gets tangled among them. The […]
The Image This image has been created within the collaboration between Descubre Foundation, the Centro Astronómico Hispano Alemán(CAHA), the Documentary School of Astrophotography (DSA) and the Astronomical Observatory of the University of Valencia (OAUV). Data have been acquired using the 1.23 meter Zeiss telescope at Calar Alto Observatory, and processed using PixInsight. The final image results from the combination […]
