How do astronomers estimate the mass of a galaxy?
Astronomers estimate the mass of a galaxy by observing the motions of its stars and gas. By studying the dynamics of these components, such as …

Astronomers classify galaxies primarily based on their morphology, or visual appearance. This classification system, known as the Hubble sequence, categorizes galaxies into three main types: …
Galaxies are classified based on their visual appearance, primarily into three main types: spiral, elliptical, and irregular. This classification system, known as the Hubble sequence, …
Black holes are intimately linked to galaxies, often found at their centers. Supermassive black holes, millions to billions of times more massive than the sun, …
Yes, both the Large Magellanic Cloud (LMC) and the Small Magellanic Cloud (SMC) are visible from Ireland, although they are best observed from southern latitudes. …
Yes, the Andromeda Galaxy (M31) is visible from Ireland. Under dark skies with minimal light pollution, it can be seen as a faint, fuzzy patch …
Yes, a few galaxies are visible to the naked eye under optimal viewing conditions. The most prominent example is the Andromeda Galaxy (M31), which appears …
Yes, other galaxies are visible from Earth. By using telescopes, both amateur and professional astronomers can observe distant galaxies beyond our own Milky Way. Telescopes …
Yes, many galaxies are observable from Ireland using binoculars or small telescopes. While the views may not be as detailed as those obtained with larger …
Yes, galaxies can collide and merge with each other due to gravitational interactions. When galaxies come close together, their gravitational attraction can overcome the outward …
