SDSS J0100+2802 - At a distance of 12.8 billion light years from earth, SDSS J0100+2802 is a hyperluminous quasar located near the border of the constellations Pisces and Andromeda. It was formed 900 million years after the Big Bang. About four times more luminous than SDSS J1148+5251, and seven times more luminous than ULAS J1120+0641, it is the most distant quasar known. It harbors a black hole with mass of 12 billion solar masses. The diameter of this black hole is about 70.9 billion kilometres. James Webb Space Telescope is scheduled to observe J0100+2802 on Aug 22, 2022.

HD 189733 is a binary star system located at a distance of 64.5 light-years away in the constellation of Vulpecula (the Fox). The primary star is believed to be an orange dwarf star, while the secondary star is a red dwarf star. HD 189733 A has one known planet, designated HD 189733 b, a gaseous giant 13% larger than Jupiter close enough to complete an orbit every two days. Based on spectrometry data gathered in 2007 it was observed that this planet contains significant amounts of water vapor. This planet is the second extrasolar planet where definitive evidence for water has been found. Although its unlikely that HD 189733b with atmospheric temperatures rising above 1,000 °C (1,830 °F) is habitable, but its existence is a proof that water, an essential component of life, would be found on a more Earth-like planet in the future. James Webb Space Telescope is scheduled to observe HD-189733 on Aug 23, 2022.

WASP-77 A b is a gas giant exoplanet that orbits a G-type star. Its mass is 1.667 Jupiters, it takes 1.4 days to complete one orbit of its star, and is 0.02335 AU from its star. Its discovery was announced in 2012. James Webb Space Telescope is scheduled to this exoplanet on Aug 24, 2022.

At a distance of about 32 million light years away, Messier 74 also known as NGC 628 or Phantom Galaxy is a large spiral galaxy in the equatorial constellation Pisces. The galaxy contains two clearly defined spiral arms and is therefore used as an archetypal example of a grand design spiral galaxy. Its low surface brightness makes it the most difficult Messier object for amateur astronomers to observe. However, this galaxy was one of the objects observed by James Webb Telescope in July 2022. James Webb Space Telescope is scheduled to observe this galaxy again on Aug 25, 2022.

Located at a distance of 1000 light years, NGC 1333 is a stellar nursery with pre-planetary disk of dust surrounding an embryonic star within this region, called NGC 1333-IRAS 4B which is drenched with water vapor. NGC 1333 is located in Perseus constellation. It is a cloud of gas and dust that is busy manufacturing new stars. Spitzer surveyed four of the very youngest stars in this region and 26 others elsewhere, but found only one, NGC 1333-IRAS 4B, with water vapor. James Webb Space Telescope is scheduled to observe IRAS 4B on Aug 28, 2022.
