A spiral galaxy is a type of galaxy characterized by a flat, disk-like structure and a central bulge with winding, pinwheel-like arms of stars and gas. These arms, which are made up of dust, gas, and young, hot stars, are thought to be formed by density waves that sweep through the disk of the galaxy, causing the gas and dust to compress and form new stars.
Spiral galaxies are among the most common types of galaxies in the universe, and they come in a range of sizes, from small, dwarf spiral galaxies to larger, more massive ones. The Milky Way, the galaxy that our solar system is a part of, is a spiral galaxy.
NGC 6956: a spiral galaxy located 214 million light-years away
The NGC 6956 spiral galaxy now enters the cosmic stage, as the Hubble telescope captured a new photo of it.

NGC 6956 is a spiral galaxy located within the Delphinus constellation. This galaxy can be seen from both hemispheres of the Earth at various times throughout the year, as it is positioned relatively close to the celestial equator. This makes it an easily visible and accessible target for observation from many locations on our planet. In addition to its convenient location, NGC 6956 is also a particularly interesting galaxy to study due to its spiral structure and active star-forming regions. With its unique features and easily visible location, NGC 6956 is an important object of study for astronomers and other scientists.
NGC 6956 has a diameter of approximately 95,000 light years. This makes it a relatively large galaxy compared to other types of galaxies.
There are several things that make the Hubble telescope special. One of the most significant features of the Hubble telescope is its location in space. Because it is above the Earth’s atmosphere, Hubble is able to capture images and spectra with much greater clarity and resolution than telescopes on the ground.
