Summary[edit]
| Description |
English: A unique ultra-faint dwarf galaxy has been discovered in the outer fringes of the Andromeda Galaxy thanks to the sharp eyes of an amateur astronomer examining archival data from the US Department of Energy-fabricated Dark Energy Camera on the Víctor M. Blanco 4-meter Telescope at Cerro Tololo Inter-American Observatory (CTIO) and processed by the Community Science and Data Center (CSDC). Follow-up by professional astronomers using the International Gemini Observatory revealed that the dwarf galaxy — Pegasus V — contains very few heavier elements and is likely to be a fossil of the first galaxies. All three facilities involved are Programs of NSF's NOIRLab.
Español: Una galaxia enana de bajo brillo y única en su especie, fue descubierta en los bordes exteriores de la Galaxia de Andrómeda gracias a los agudos ojos de un astrónomo aficionado que examinaba los datos de archivo de la Cámara de Energía Oscura, fabricada por el Departamento de Energía de EE. UU. e instalada en el Telescopio Víctor M. Blanco de 4 metros, en el Observatorio de Cerro Tololo (CTIO), y que fueron procesados por el Community Science and Data Center (CSDC). El seguimiento posterior realizado por astrónomos profesionales utilizando el Observatorio Internacional Gemini, reveló que la galaxia enana, Pegasus V, contiene muy pocos elementos pesados y es probable que sea un fósil de las primeras galaxias. Las tres instalaciones involucradas en el hallazgo son programas de NOIRLab de NSF. |
