James Webb Space Telescope Weekly Schedule Aug 08, 2022 to Aug 15, 2022

August 07, 2022

James Webb Space Telescope had a very exciting and busy last week that was spent observing 10-Hygiea, HD 141569, NGC 5139, Ganymede, Ring Nebula and HD 140986. For more details regarding these observations, check out last week's schedule here. Following are the major objects that James Webb Space Telescope will study this week (Aug 08 to Aug 15, 2022) as per the schedule published here.

EM-AS-209 is a proto planetary disk around T-Tauri stars. T Tauri stars (TTS) are a class of variable stars that are less than about ten million years old. This class is named after the prototype, T Tauri, a young star in the Taurus star-forming region. They are found near molecular clouds and identified by their optical variability and strong chromospheric lines. James Webb Space Telescope is scheduled to observe proto planetary disks around T-Tauri stars on Aug 8, 2022

Dwarf Galaxy - NGC-5940 - Credit: NASA/ESA Hubble

DRACO-F1 - The nearest galaxies to our own Milky Way are its companion dwarf galaxies, which are much smaller than the Milky Way. Draco is one of the dwarf galaxies. The orbits of the stars are governed by the gravity arising from the dark matter in each galaxy. By studying how the stars move, the researchers will be able to determine how the dark matter is distributed in these galaxies. James Webb Space Telescope is scheduled to observe DRACO-F1 Dwarf spheroidal galaxies on Aug 9, 2022.

NGC 1052 is located at a distance of around 63 million light years from the Milky Way, and has a LINER-type active galactic nucleus which signals the intense starburst activity in the galaxy's center that were confirmed with observations with better resolution showing a number of star-forming regions and young star clusters. NGC 1052 shows also two small jets emerging from its nucleus as well as a very extended disc of neutral hydrogen, far larger than the galaxy itself. The shape of NGC 1052 is thought to be a triaxial ellipsoid. James Webb Space Telescope is scheduled to observe NGC-1052 galaxy on Aug 10, 2022.

WASP-18 is a magnitude 9 star located in the Phoenix constellation of the southern hemisphere. It has a mass of 1.25 solar masses. WASP-18b is a “hot Jupiter,” a giant exoplanet that orbits very close to its star, located about 330 light years from Earth. Specifically, the mass of WASP-18b is estimated to be about ten times that of Jupiter, yet it orbits its star about once every 23 hours. By comparison, it takes Jupiter about 12 years to complete one trip around the sun from its great distance. James Webb Space Telescope is scheduled to observe Wasp 18 on Aug 11, 2022.

NGC 1365, also known as the Great Barred Spiral Galaxy, is a double-barred spiral galaxy about 56 million light-years away in the constellation Fornax. NGC 1365, including its two outer spiral arms, spreads over around 200,000 light-years. Different parts of the galaxy take different times to make a full rotation around the core of the galaxy, with the outer parts of the bar completing one circuit in about 350 million years. James Webb Space Telescope is scheduled to observe NGC-1365 on Aug 13, 2022.

Located at a distance of about 30 million light years in the constellation Andromeda, this large spiral galaxy NGC 891 spans about 100 thousand light-years and is seen almost exactly edge-on from our perspective. NGC 891 looks similar to Milky Way. It has a flat, thin, galactic disk of stars and a central bulge cut along the middle by regions of dark obscuring dust. James Webb Space Telescope is scheduled to observe NGC-891 on Aug 15, 2022.
