1/5 Milky Way Galaxy and the Bioluminescent Sea (May 29) - It is a breathtaking snapshot of the Milky Way Galaxy captured over the bioluminescence of the sea in the Maldives. What is the turquoise glow in the water? It occurs due to single-celled Plankton, known as Noctiluca scintillans, which illuminate when stimulated by the sea waves to keep predators away.

2/5 Stellar Dumbbell Nebula (May 30) - Planetary nebula M27, also known as the Dumbbell Nebula, is located about 1360 light-years away towards the constellation of Vulpecula. The Dumbbell Nebula was the 27th object and the first ever planetary nebula discovered and catalogued by French astronomer Charles Messier in 1764, one of the most influential figures in the history of astronomy.

3/5 Formation of our Universe throughout history (May 31) - This is an amazing computer simulation of our Universe as it developed throughout history. This simulation tracks gases leading from the early Universe till today. As the simulation goes on, the formation of a disk galaxy takes place. For the unaware, Disk Galaxies are formed when two or more galaxies merge, resulting in a pancake-shaped disk of stars. Our own Milky Way Galaxy is one such disk galaxy, and it will collide with the Andromeda Galaxy in the distant future, according to NASA. (NASA/ TNG Collaboration/MPCDF/FAS Harvard U)
4/5 Supernova Remnant Cassiopeia A (June 1) -  It is a snapshot of Cassiopeia A, a supernova remnant located about 11000 light-years from Earth towards the constellation of Cassiopeia. When a star explodes, the subsequent explosion which takes place, known as a Supernova, is the largest explosion to occur in space. According to NASA, a supernova happens when there is a change in the core, or center, of a star. A change can occur in two different ways, with both resulting in a supernova. (NASA/Hubble/CXC)
5/5 Pinwheel Galaxy Messier 101 (June 2) - In this image, Messier 101, also known as the Pinwheel Galaxy can be seen located about 25 million light-years away towards the Northern constellation of Ursa Major. Messier 101 is one of the last objects catalogued by Charles Messier and it is a massive pinwheel galaxy that spans about 170,000 light-years across. According to NASA, Messier 101 is also one of the first spiral nebulae to be observed by Lord Rosse's large 19th-century telescope, the Leviathan of Parsontown. (NASA/ESA/Hubble)

Pluto's largest moon Charon's size is about one-tenth that of planet Earth. (NASA, Johns Hopkins Univ./APL, Southwest Research Institute, U.S. Naval Observatory)

Pluto's orbit is highly elliptical. And due to its relatively small size and a considerable distance from Earth, Pluto's characteristics and features have remained largely a secret until the New Horizons spacecraft conducted a flyby in July 2015. This mission provided crucial data about this distant world. Among the discoveries made during the New Horizons mission, it was found that Charon, one of Pluto's five moons, holds a significant role. Charon is not only the largest of Pluto's moons, but it is also the largest known satellite relative to its parent body in our entire solar system. In fact, Charon's diameter is roughly half that of Pluto itself.

Today's NASA Astronomy Picture of the Day is a portrait of Pluto's largest moon - Charon. In this high-resolution image, a captivating and enigmatic northern polar region, referred to by some as Mordor Macula, dominates the foreground. This mesmerizing portrait of Pluto's moon Charon was captured by the New Horizons spacecraft during its closest approach on July 14, 2015. Interestingly, this very same point was instrumental in the groundbreaking discovery of Charon by James Christy and Robert Harrington at the U.S. Naval Observatory in Flagstaff back in June 1978.

NASA's explanation about largest Moon of Pluto

While sharing the image, NASA explained that using a combination of blue, red, and infrared data, the collected information was processed to enhance colours and track changes in Charon's surface properties, providing a remarkable resolution of approximately 2.9 kilometres (1.8 miles). The resulting image showcases the interesting Pluto-facing hemisphere of Charon, revealing a prominent belt of fractures and canyons encircling the moon, seemingly separating smooth plains in the south from diverse terrain in the north.

Did you know? Measuring 1214 kilometres (754 miles) in diameter, Charon's size is about one-tenth that of planet Earth, NASA revealed. Despite its significant dimensions, in the grainy, negative, telescopic picture inset at the upper left, Charon appears as a small bump positioned roughly at the 1 o'clock position on Pluto's disk.
