NASA, with the help of its various advanced telescopes such as Spitzer Space Telescope, the Hubble Space Telescope, and the newly launched James Webb Space Telescope, has published fascinating images of galaxies thousands and even millions of light-years away. Some of these include Centaurus A Galaxy, Hamburger Galaxy, Rubin's Galaxy, Arp 78 and more. These galaxies exhibit an array of sizes, ranging from diminutive dwarf galaxies with a meager population of a few billion stars to colossal elliptical galaxies with trillions of stars. Moreover, some of these galaxies have unusual shapes like a hamburger, toothpicks, rings and more.

Today's NASA Astronomy Picture of the Day is a snapshot of NGC 1566, also known as the Spanish Dancer Spiral Galaxy, located about 40 million light-years away towards the constellation of Dorado. Within the galaxy are blue star clusters and dark cosmic dust lanes which follow two prominent spiral arms. According to NASA, several images of this galaxy have been captured to study star formation, supernovas, and the spiral's unusually active center.

The image was captured by the Hubble Space Telescope which is run by NASA and ESA in collaboration, and was processed by Detlev Odenthal.

 This stunning discovery by the Hubble Telescope further proves the capabilities of the Hubble Space Telescope. Despite being nearly 3 decades old, it still amazes us with stunning images of far-off celestial objects.

To capture such objects, Hubble has advanced optical instruments such as the Advanced Camera for Surveys and Wide Field Camera 3. The Advanced Camera for Surveys (ACS) was primarily designed to survey large areas of the sky at visible and red wavelengths with 10 times greater efficiency than the earlier
