The Hubble Legacy Field brings together 7500 individual exposures from the Hubble Space Telescope (HST).

The Hubble Legacy Field is a photograph released in 2019 that brings together 7500 individual exposures from astronomy programs conducted over two decades by the Hubble Space Telescope (HST). This mosaic includes the famous deep field, ultra-deep field, and the eXtreme deep field shots.

The photograph covers a region slightly smaller than the size of the full moon of a region in the constellation of Fornax, specifically at 3h 33m, of Right ascension and at a declination of -27° 47′. Some 265,000 galaxies covering a period of 13.3 billion years, and wavelengths from the near-infrared to the ultraviolet, can be seen on the scene. Thus, the Hubble Legacy field contains 30 times more galaxies than the ultra-deep field available for more than a decade, and is a tool for studying the evolution of galaxies.

The Hubble Legacy Field image is available here, and also, those interested can access this page that contains detailed information about the projects and the images used for the mosaic.

M10 – Globular Cluster | Cúmulo Globular

M10 is a very bright and star-rich cluster. Located in the constellation Ofiuco, it is estimated to be approximately 16,000 light-years from the center of our galaxy. An analysis of its radial velocity allows us to deduce that it is moving away from Earth at more than 271,440 km/h.

M9 – Globular Cluster | Cúmulo Globular

Like all globular clusters, M9 is a spectacle in itself, and one of the oldest and most intriguing objects in our galaxy. M9 stands out as one of the closest globular clusters to the center of our galaxy, only 5,500 light-years away.

M8 – Lagoon Nebula | Nebulosa de la Laguna

Like all emission nebulae, M8 or NGC 6523 is a gigantic HII region, that is, a spectacular cradle of stars. With a magnitude of 5.8, this incredible nebula boasts many large, hot stars, whose ultraviolet radiation sculpts the gases and cosmic dust, giving it its characteristic shape.

M7 – Open Cluster | Cúmulo Abierto

Also known as NGC 6475, M7 is an open cluster, that is, a group of gravitationally bound stars formed by the same molecular cloud. It is a very sparse cluster, located in a very rich region of the Milky Way.

M6 – Open Cluster | Cúmulo Abierto

This beautiful cluster comprises more than 200 stars and has a diameter of about 12-20 light-years. It is estimated that its stars were formed about 100 million years ago, which means that while dinosaurs roamed the planet, M6 was just beginning to shine in the sky.

M5 – Globular Cluster | Cúmulo Globular

The globular cluster M5 is probably one of the most interesting because it is one of the oldest, largest, and brightest clusters. It is located in the constellation of The Serpent (Serpens) at a distance of approximately 24,500 light-years.

Galileo and the Church

“The earth revolves around the sun and not the other way around. This phrase is not impressive for the present generations, but for those who lived in the 17th century it was a true revolution. When Galileo Galilei exposed it, based on the first observations made through a telescope, it caused such a commotion that it shook the foundations of the Church.

Dark matter: the invisible component of the universe

It is estimated that dark matter constitutes 23% of the total matter/energy content of the universe. However, its components are not yet known; its nature is an enigma to modern cosmology and finding it is currently one of the greatest challenges of science.

M4 – Globular Cluster | Cúmulo Globular

Also called NGC 6121, M4 is the closest globular cluster to the Earth. M4 contains about 100,000 stars, and like most globular clusters, it is a very old structure, about 12-13 billion years old.
