Astounding Photo of NGC 3156 Captured by Hubble Space Telescope

A stunning new photo from the Hubble Space Telescope captures the hazy glow of a distant galaxy.

The galaxy known as NGC 3156 is located about 73 million light years from Earth in the constellation Sextans. This galaxy is categorized as a lenticular galaxy which is a cross between a spiral and an elliptical galaxy because it has a bright central bulge but no obvious twisting arms. Lenticular galaxies are also believed to have depleted or lost much of their interstellar material, indicating that they are home to populations of older stars.

In the latest photo of NGC 3156, the faint concentric ovals appear increasingly brighter towards the core when compared with the fading edges of the galaxy NGC 3156. Two dark red threads of interstellar dust crisscross the galaxy’s disk, surrounding its central bulge. Relatively few cosmic neighbors are captured in the surrounding regions of space.

The constellation Sextan occupies a sparse and relatively dark region of the sky. It is a small equatorial constellation that belongs to the Hercules family of constellations and is named after an astronomical instrument used to measure the angular distance between two visible objects in the sky.

“The sextan is often thought to be a navigational instrument invented in the 18th century. However, sextants as astronomical tools have been around much longer than that: Islamic scholars developed astronomical sextants hundreds of years earlier to measure angles in the sky,” European Space Agency (ESA) officials said. said in a statement releasing a new Hubble photo of NGC 3156.

“A particularly striking example is the giant sextant with a radius of 36 meters developed by Ulugh Beg of the Timurid dynasty in the fifteenth century, located in Samarkand in the region of present-day Uzbekistan,” the ESA official said. “This early sextant may have been a development of the quadrant, a measuring device proposed by Ptolemy.”

Sextants have long been replaced by more sophisticated instruments such as the Hubble Space Telescope — a joint mission led by ESA and NASA — which are capable of measuring the positions of stars and astronomical objects more accurately and precisely.

Hubble took this latest photo, which was released online on September 11, using data from the Advanced Camera for Surveys and Wide Field Camera 3. Hubble has helped astronomers study the positions of galaxies, star populations (including dense galaxy globular clusters) and black holes. supermassive at its core.
