James Webb Space Telescope Weekly Schedule Oct 31, 2022 to Nov 07, 2022

October 30, 2022

Last week James Webb Telescope observed several objects including Messier 71 or M71, Cassiopeia, I Zwicky 18, Trappist-1 system of seven rocky worlds, very distant young galaxy A2744 YD4. For more details regarding these observations, check out last week's schedule here. This week, James Webb Telescope is scheduled to observe Crab nebula, Saturn's moon Titan, Galaxy NGC 7250, Exoplanets such as Trappist-1b and GJ 3470, Abell 2744, asteroids such as 1996TL66, 2005RN43, 2014LV28, OKYRHOE, 2002XV93, 2004PF115, 2004XA192, 2004PG115  among other objects. Following are the major objects that James Webb Space Telescope will study this week (Oct 31 to Nov 07, 2022) as per the schedule published here. File Link

The Crab Nebula, which is around 6,500 light-years from Earth, is the remains of a star that had roughly 10 times the mass of our Sun when it first began its life. When it burst as a supernova on July 4, 1054, its existence came to an end. The Hubble Space Telescope focused on the Crab's center in this image and zoomed in to expose its structure in unparalleled detail. James Webb Telescope is scheduled to observe Crab Nebula on October 31, 2022.

Abell 2744, also known as Pandora's Cluster, is a massive galaxy cluster that formed when at least four smaller galaxy clusters simultaneously collided over a period of 350 million years. It is located about 4 billion light years away from Earth. The gas that makes up about 20% of the cluster's mass is so hot that it can only be seen in X-rays. The remaining mass is made up of dark matter, which accounts for about 75% of the cluster's mass. Along with several other Abell clusters, this cluster also exhibits a radio halo. Strong central halo and a lengthy tail are present, and the tail may be an extension of the central halo or relic radiation. James Webb Telescope is scheduled to observe ABELL 744 on November 04, 2022.

Titan - Credit: NASA/JPL-Caltech/Space Science Institute

The second-biggest natural satellite in the Solar System, Titan is Saturn's largest moon. It is the only moon that has been found to contain a stable body of surface liquid, and it is the only known object in space besides Earth to have a dense atmosphere. One of the gravitationally spherical moons orbiting Saturn, Titan is the second-farthest moon from its parent planet. Titan, which is frequently compared to a planet-like moon, is 80% more massive and 50% larger (in diameter) than the moon of Earth. It is bigger than the planet Mercury but only 40% as massive as Jupiter's moon Ganymede, making it the second-largest moon in the Solar System. James Webb Telescope is scheduled to observe Titan on November 04, 2022.

Trappist 1b - Artist Concept - Credit: NASA

Exoplanet TRAPPIST-1b, which is mostly rocky and resembles Venus, orbits the ultra-cool dwarf star TRAPPIST-1, which is located around 40 light-years (12 parsecs) from Earth in the constellation of Aquarius. By dimming the host star's brightness as it passes in front of the planet, the transit method was used to find the planet. It was first announced on May 2, 2016, and more research was able to hone its physical parameters between 2017 and 2018. The planet has a mass similar to Earth's but is 12% bigger. It possesses an exceptionally thick and heated atmosphere, which has been confirmed by spectroscopic studies and its comparatively low density. James Webb Telescope is scheduled to observe Trappist 1b on November 05, 2022.

An irregular galaxy called NGC 7250 can be found in the Lacerta constellation. It is a blue galaxy with spectacular bursts of star formation; its star-forming pace exceeds the Milky Way's by more than an order of magnitude. A type Ia supernova was discovered in the galaxy in 2013 and given the name SN 2013dy. It was the earliest known supernova detection at the time, having been discovered 2.4 hours after the explosion. The brighter star in front of the galaxy, designated TYC 3203-450-1, has received little research. The galaxy itself is around a million times farther away from Earth. James Webb Telescope is scheduled to observe NGC 7250 on November 05, 2022.
