NASA and ESA's Hubble Space Telescope revisited the dwarf galaxy NGC 1705 in the constellation Pictor, roughly 17 million light-years from Earth.
NGC 1705 is a tiny, irregularly shaped galaxy that recently had an active era of star production, a process known as starburst, according to the European Space Agency (ESA).
Space.com said this type of irregular dwarf galaxy has fewer elements than bigger galaxies and is primarily made up of hydrogen and helium. They are assumed to be comparable to the universe's first galaxies as a result of this.
NASA/ESA Hubble Space Telescope Captures Irregular Dwarf Galaxy
The space agency stated per Republic World that irregular dwarf galaxies like NGC 1705 have fewer elements than bigger galaxies and are mostly composed of hydrogen and helium. They are assumed to be comparable to the universe's first galaxies as a result of this.

The galaxy NGC 1705 has been observed twice by the NASA/ESA Hubble Telescope, the first time in 1999 with a different camera, which yielded a significantly less detailed image than this year's record.
SciNews said English astronomer John Herschel found this galaxy, also known as ESO 158-13, IRAS 04531-5326, and LEDA 16282, on December 5, 1834.
Near the galactic center of NGC 1705 is a megastar cluster known as NGC1750-1. The galaxy belongs to the Dorado Group, consisting of more than ten spiral and elliptical galaxies.
ESA Merges Hubble Space Telescope Camera Data To Make Unique Filters of NGC 1705
ESA said this image was acquired using Hubble's Wide Field Camera 3 to examine a specific light wavelength known as H-alpha. By studying at this wavelength, astronomers hoped to find locations where young, active stars emit ultraviolet light into the gas clouds around them.
Sputnik Brazil said ESA published the image by merging multiple views from Hubble's cameras using seven distinct filters. The goal is to look at how stars and gases interact in the region of a galaxy with a high rate of star creation.
In addition to the beautiful reddish image seen by the telescope, ESA stated that the data gathered from this sort of observation could aid in deciphering riddles surrounding the Universe's beginning.
About Hubble Space Telescope
The Hubble Space Telescope is massive, NASA said. Hubble orbits Earth at around 340 miles (547 kilometers). It measures the length of a huge school bus and weighs the equivalent of two adult elephants. Hubble travels at a pace of around 5 miles per second, about the same as traveling from the east to the west coast of the United States in 10 minutes. Hubble is a spacecraft that runs on solar power.
Hubble pictures astronomical objects such as planets, stars, and galaxies in great detail. Hubble has recorded more than a million observations. Among these are detailed photographs of star birth and death, galaxies billions of light-years away, and comet fragments colliding with Jupiter's atmosphere.
NASA named Hubble Space Telescope after Edwin P. Hubble, an American astronomer. In the early 1900s, he made significant discoveries. He demonstrated that the Milky Way, which contains our solar system, is just one among countless galaxies.
His study contributed to the discovery that the universe is expanding. This gave rise to the big-bang hypothesis, which states that the universe began with a massive explosion of energy and has continued to expand ever since.
