Right from taking images of aeging to dying stars, Hubble Space Telescope has given us a visual treat of the Outerspace. And now, Hubble Space Telescope, which belongs to the National Aeronautics and Space Administration (NASA) and the European Space Agency (ESA), snapped the breathtaking image of a galaxy named NGC 1803. It is to be noted that NGC 1803 is about 200 million light-years away, in the southern constellation of Pictor.
NGC 1803 was first discovered in 1834 by astronomer John Herschel. This galaxy is one of a galactic pair. It was described by Dreyer as being “faint, small, [and] round,” and located near to a very bright star to the southeast. This star is, in fact, the nebulous lenticular galaxy PGC 16720 — not visible in this image.
In a statement, Hubble said, Herschel is a big name in astronomy; John, his father William and his aunt Caroline all made huge contributions to the field, and their legacies remain today. William systematically cataloged many of the objects he viewed in the night sky, named many moons in the solar system, discovered infrared radiation and more. Caroline discovered several comets and nebulas.”
“John took this aforementioned catalog of night-sky objects and reworked and expanded it into his General Catalogue of Nebulae and Clusters of Stars. This was the basis for the cataloging system still used today by astronomers, John Louis Emil Dreyer’s New General Catalogue of Nebulae and Clusters of Stars, or the New General Catalogue for short. This gives rise to the NGC names assigned to a vast number of galaxies — including NGC 1803,” it added.
Recently, using the Hubble Space Telescope and new observation technique, astronomers unearthed the smallest known dark matter clumps. NASA has confirmed that dark matter forms are much smaller clumps than previously known.
