James Webb Space Telescope Weekly Schedule Aug 15, 2022 to Aug 22, 2022

August 13, 2022

Last week James Webb Space Telescope focused on observing proto stars, Wasp 18 exoplanet systems, galaxies such as NGC 1365, NGC-1052, NGC-891 and M-16 Nebulae. For more details regarding these observations, check out last week's schedule here. Pulsars, Comets, Protostars, Galaxies including Andromeda are amongst some of the objects scheduled for observation in coming days. Following are the major objects that James Webb Space Telescope will study this week (Aug 15 to Aug 22, 2022) as per the schedule published here. File Link

Sculptor Galaxy/NGC 253 - Credit: NASA/JPL Caltech

Located at a distance of 11.42 million light years, the Sculptor galaxy NGC 253, is part of a cluster of galaxies visible to observers in the Southern hemisphere. It is known as a starburst galaxy for the extraordinarily strong star formation in its nucleus. This activity warms the surrounding dust clouds, causing the brilliant yellow-red glow in the center of this infrared image. James Webb Space Telescope is scheduled to observe Sculptor on Aug 15, 2022

At a record 12.91 billion light years away, SXDF-NB1006-2 is a distant galaxy located in the Cetus constellation. It was discovered by the Subaru XMM-Newton Deep Survey Field. The galaxy was claimed to be the most distant galaxy at announcement in June 2012, as the more distant claimants were not confirmed spectroscopically at that time. It exceeded the previous confirmed distance holder, It contains the oldest oxygen in the Universe


Discovered in May 2017, PANSTARRS-C17K2 is an Oort cloud comet with an inbound hyperbolic orbit, at a distance beyond the orbit of Saturn when it was 16 AU (2.4 billion km) from the Sun. It had been in the constellation of Draco from July 2007 until August 2020. The Hubble Space Telescope observed K2 when it was 1.5 billion miles from the Sun, halfway between the orbits of Saturn and Uranus. The observations revealed a fuzzy cloud of dust, called a coma, surrounding the icy visitor, evidence that the frozen comet is being warmed by the Sun and releasing material. K2 is the farthest active inbound comet ever observed. James Webb Space Telescope is scheduled to observe this comet on Aug 16, 2022.

Triangulam Galaxy/M33 - Credit: NASA/Swift Science Team/Stefan Immler

The Triangulum Galaxy is also called M33 for being the 33rd object in Charles Messier’s sky catalog. It is located about 2.73 million light-years from Earth in the constellation Triangulum. M33 is over 50,000 light-years in diameter, third largest in the Local Group of galaxies after the Andromeda Galaxy (M31), and our own Milky Way. M33 is itself thought to be a satellite of the Andromeda Galaxy. Despite sharing our Milky Way’s spiral shape, M33 has only about one-tenth the mass and is believed to have 40 billion stars. M33’s visible disk is about 50,000 light-years across, half the diameter of our galaxy. James Webb Space Telescope is scheduled to observe this galaxy on Aug 19, 2022.

Andromeda Galaxy/M31 - Credit: NASA/JPL Caltech

Located at a distance of approximately 2.5 million light-years away, the Andromeda galaxy, or M31, is our Milky Way's largest galactic neighbor. The entire galaxy spans 260,000 light-years across. Andromeda is one of only ten galaxies that can be spotted from Earth with the naked eye. James Webb Space Telescope is scheduled to observe this galaxy on Aug 19, 2022.
