1/5 Double Star Cluster (Feb 20) - It is a 100-million-year-old globular star cluster located 160,000 light-years away in the constellation Dorado. What’s unusual about this star cluster is its size and shape is reminiscent of the other ancient star clusters in the Milky Way Galaxy. However, this double star cluster is not present in our galaxy and belongs in the Large Magellanic Cloud. (NASA/ESA/Hubble/Paul Goudfrooij(STScI))

2/5 Comet ZTF (Feb 21) - It is a mesmerizing picture of Comet ZTF streaking across the skies over Yosemite Falls located in the Sierra Nevada region of California. According to NASA, this comet was discovered by astronomers using the wide-field survey camera at the Zwicky Transient Facility in 2022 in March last year. (NASA/Tara Mostofi)

3/5 Rising Solar Activity (Feb 22) - This picture is a snapshot of the rising activity on the surface of the Sun. This image was captured two weeks ago in a single colour of light known as Hydrogen Alpha. Solar prominences can be observed hurling out from the surface while the Sun’s edges are brighter due to increased absorption of relatively cool solar gas. (NASA/Mehmet Ergun)

4/5 Spiral Galaxy Arp 78 (Feb 23) - A peculiar spiral galaxy called Arp 78 can be seen in this image. It is an enormous galaxy which spans nearly 200,000 light-years across and exists almost 100 million light-years away in the constellation Aries. Arp 78 is also known as NGC 772. Alongside Arp 78, another faint galaxy can be seen, which is NGC 770.  (NASA/Josep Drudis)

5/5 Headphone Nebula Jones-Emberson 1 (Feb 24) - A stellar nebula known as Jones-Emberson 1 also called as the Headphone Nebula owing to its peculiar headphone-like shape. The Headphone Nebula is located about 1600 light-years away from Earth in the constellation Lynx. (NASA/Serge Brunier/Jean-Francois Bax/David Vernet/ C2PU/OCA)

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. According to NASA, Spiral Galaxies have winding spiral arms that make them look a little like massive pinwheels. These disks of stars, gas, and dust have bright bulges in their centers made up primarily of older and dimmer stars. Their whirled arms are typically full of gas and dust, which helps give rise to the bright, younger stars visible throughout their length.

NASA's Astronomy Picture of the Day is a stellar snapshot of Spiral Galaxy NGC 3169 and its neighbour NGC 3166. NGC 3169 is located almost 70 million light-years away in the constellation of Sextans (the Sextant). According to NASA, it is part of the Leo I Group of galaxies which is part of a larger galactic congregation known as the Virgo Supercluster. The two galaxies are interacting gravitationally and are expected to merge into one sometime in the future.

The picture was captured by astrophotographers Mike Selby and Mark Hanson, who have previously been published on NASA's APOD for capturing images of Cometary Globules, Wind-shaped Nebula and more.

NASA's description of the picture

Spiral galaxy NGC 3169 looks to be unraveling like a ball of cosmic yarn. It lies some 70 million light-years away, south of bright star Regulus toward the faint constellation Sextans. Wound up spiral arms are pulled out into sweeping tidal tails as NGC 3169 (left) and neighboring NGC 3166 interact gravitationally. Eventually the galaxies will merge into one, a common fate even for bright galaxies in the local universe.

Drawn out stellar arcs and plumes are clear indications of the ongoing gravitational interactions across the deep and colorful galaxy group photo. The telescopic frame spans about 20 arc minutes or about 400,000 light-years at the group's estimated distance, and includes smaller, bluish NGC 3165 at the right. NGC 3169 is also known to shine across the spectrum from radio to X-rays, harboring an active galactic nucleus that is the site of a supermassive black hole.
