NASA Astronomy Picture of the Day 9 June 2023: Webb Telescope snaps Pandora Cluster

Today’s NASA Astronomy Picture of the Day is a snapshot of Abell 2744, also known as the Pandora’s Cluster of galaxies which is located about 4 billion light-years away towards the constellation of Sculptor.

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)

Most galaxies exist in groups or clusters with dozens or hundreds of members, and these cluster galaxies are all in constant motion, pulled and twisted by their neighbour's gravity. Galaxies exist in the vastness of space, consisting of various celestial objects such as stars, clouds of dust, and gas, all of which are bound together by gravity. These galaxy clusters are the largest objects in the Universe bound by gravity and astronomers can use them to measure important cosmological properties, according to NASA.

Today's NASA Astronomy Picture of the Day is a snapshot of Abell 2744, also known as the Pandora's Cluster of galaxies which is located about 4 billion light-years away towards the constellation of Sculptor. This galaxy cluster formed when four smaller galaxy clusters piled up nearly 350 million years ago, according to NASA. Shockingly, the galaxies in this cluster only account for 5 percent of its mass while dark matter inside it accounts for nearly 75 percent!

Tech used to capture the picture

This awesome snapshot was captured by the NIRCam instrument aboard the James Webb Space Telescope (JWST). It is operated by NASA in collaboration with ESA and is used to capture various celestial objects in stunning detail with the help of its suite of highly advanced instruments and cameras.

It also has sophisticated instruments like the Near Infrared Camera (NIRCam) which is the primary camera onboard the telescope. It has three specialized filters and captures images in two different infrared ranges. NIRCam also has coronagraphic and spectroscopic capabilities and is the primary tool for the alignment of the telescope. The space telescope also has Mid-Infrared Instrument (MIRI) and NIRSpec instruments onboard which aid in capturing mesmerizing snapshots of objects in space.

NASA's description of the picture

This deep field mosaicked image presents a stunning view of galaxy cluster Abell 2744 from the James Webb Space Telescope's NIRCam. Also dubbed Pandora's Cluster, Abell 2744 itself appears to be a ponderous merger of three different massive galaxy clusters some 3.5 billion light-years away toward the constellation Sculptor. Dominated by dark matter, the mega-cluster warps and distorts the fabric of spacetime, gravitationally lensing even more distant objects.

Redder than the Pandora cluster galaxies many of the lensed sources are very distant galaxies in the early Universe, stretched and distorted into arcs. Of course distinctive diffraction spikes mark foreground Milky Way stars. At the Pandora Cluster's estimated distance this cosmic box spans about 6 million light-years. But don't panic.
