NGC 7129 is a reflection nebula located about 3,100 light-years away from Earth. Unlike emission nebulae that emit their own light due to ionization of gas, reflection nebulae do not emit light themselves. Instead, they shine by reflecting the light of nearby stars, typically young and hot stars, that are embedded within or close to the nebula. The light from these stars gets scattered and diffused by dust and gas particles in the nebula, creating a beautiful glow and giving the nebula its characteristic blue color.
NGC 7129 is associated with a young open star cluster, containing young, hot, and massive stars that formed relatively recently from the same molecular cloud of gas and dust.

M51, known as the Whirlpool, is an interacting grand-design spiral galaxy with a Seyfert 2 active galactic
nucleus. Found in the constellation Canes Venatici, and was the first galaxy to be classified as a spiral galaxy. Its distance is estimated to be 23 million light-years away from Earth. The galaxy and its companion, NGC 5195, are easily observed by amateur astronomers, and the two galaxies may be seen with binoculars. Long exposures reveal a large nebula extending beyond the visible circular appearance. The spiral structure of the Whirlpool is believed to be the result of the close interaction between it and its companion galaxy NGC 5195, which may have passed through the main disk of M51 about 500 to 600 million years ago.
M31, known as the Andromeda Galaxy, is a spiral galaxy approximately (2.54 million light-years) from Earth, and the nearest major galaxy to the Milky Way.

M31, known as the Andromeda Galaxy, is a spiral galaxy approximately (2.54 million light-years) from Earth, and the nearest major galaxy to the Milky Way. The galaxy's name stems from the area of the Earth's sky in which it appears, the constellation of Andromeda. Its magnitude is 3.44 and can be seen by the naked eye on moonless nights even from a moderate light polluted area. The Andromeda Galaxy has a diameter of about 220,000 light-years roughly 1.5 times larger than our Milky Way and has ~ 1 trillion stars. The Andromeda Galaxy was formed roughly 10 billion years ago from the collision and subsequent merger of smaller protogalaxies. Over the past 2 billion years, star formation throughout Andromeda's disk is thought to have decreased to the point of near-inactivity. There have been interactions with satellite galaxies like M32, M110, or others that have already been absorbed by Andromeda Galaxy.

NGC4631, known as the Whale Galaxy, is a barred spiral galaxy in the constellation Canes Venatici. This
galaxy's slightly distorted wedge shape gives it the appearance of a herring or a whale, hence its nickname. Because this nearby galaxy is seen edge-on from Earth, professional astronomers observe this galaxy to better understand the gas and stars located outside the plane of the galaxy. NGC 4631 contains a central starburst,
which is a region of intense star formation. The strong star formation is evident in the emission from ionized hydrogen and interstellar dust heated by the stars formed in the starburst. This galaxy is located about 30 million light years from earth at a magnitude of 9.8.

The Antennae Galaxies (also known as NGC 4038/NGC 4039 are a pair of interacting galaxies in the constellation Corvus. They are currently going through a starburst phase, in which the collision of clouds of gas and dust, with entangled magnetic fields, causes rapid star formation. The nuclei of the two galaxies are joining to become one giant galaxy. Most galaxies probably undergo at least one significant collision in their lifetimes.
The gibbous moon is one of the various phases that the Moon goes through during its monthly lunar cycle. The moon is said to be in the gibbous phase when it can be seen from Earth with more than half but not all of the apparent disk illuminated. This phase actually happens twice each month during the waxing gibbous phase and the waning gibbous phase.

A total solar eclipse is an amazing sight to behold, and the diamond ring of the eclipse is one of the most beautiful aspects of this natural phenomenon. The diamond ring is created when the sun’s corona is visible through the moon’s thin atmosphere during a total eclipse. This ring appears for just a few seconds before the sun is completely obscured by the moon.
