The Pinwheel Galaxy (also often known as Messier 101, M101 or NGC 5457) is a face-on spiral galaxy distanced 21 thousand light-years (six megaparsecs) away…

The Triangulum Galaxy is sometimes informally known as the “Pinwheel Galaxy” by some amateur astronomy references and in most public outreach web sites. The Triangulum…

Whirlpool Galaxy is an interacting grand-design spiral galaxy in milky way. Other name of this galaxy are Messier 51a, M51a, or NGC 5194 etc. In this article briefly…

The satellite galaxy is a galaxy that orbits a greater galaxy due to gravitational attraction. Although a galaxy consists of a lot of objects (such…

Galaxy mergers are important because the merging rate is fundamental measurement of galaxy evolution. The merger rate also provides astronomers with clues about how precisely…

A giant galaxy interacting having its satellites is common. Interacting galaxies (colliding galaxies) are galaxies whose gravitational fields create a disturbance of one other. An…

A dwarf galaxy is a small galaxy composed all the way to several billion superstars, a small number compared to our own Milky Way’s 200–400…

Tidal forces are depending on the gradient of a gravitational field, as opposed to its strength, and for that reason tidal effects tend to be…

Standing wave is a wave in a medium during which each point around the axis of the wave has a associated constant amplitude. The locations…

Tidal resonance occurs once the tide excites among the resonant modes with the ocean. The effect is most striking every time a continental shelf is…

This tidal force is a secondary effect of the force of gravity and accounts for the tides. It arises for the reason that gravitational force…

Gravitational waves are one of the greatest predictions of Einstein’s theory of general relativity. In general relativity, gravitation is explained over the curvature of spacetime.…
