What Is An Elliptical Galaxy? (Explained!)

Galaxies come in all shapes and sizes, and ellipticals are some of the largest, with huge spherical gatherings of up to a trillion stars. They possess an ellipsoidal and smooth shape, and most comprise older, low-mass stars. They have very little gas or dust within their systems, which often prevents them from forming new stars. … Read more

What Is The Black Eye Galaxy? (Explained!)

The Black Eye Galaxy is a barred spiral galaxy that lies 17 million light-years away from Earth. It gained fame after its discovery in 1779 for its unique “eye-like” appearance caused by a dust band that partially covers the galaxy’s nucleus. And the unique nature of this formation doesn’t end there. Continue reading to find … Read more

What Is A Hypernova? (Explained!)

A hypernova, also known as a collapsar, is a highly energetic supernova resulting from the core collapse of a massive star. While it is similar to a supernova, it is far more powerful and exudes much more light. The jets formed from a hypernova create gamma-ray bursts (GRBs), which could be responsible for mass extinction … Read more

Why Are Galaxies So Far Apart? (Explained!)

Space, time, and distance are far more complicated than we imagine unless, of course, you’re a scientist who makes these calculations and understandings a part of their daily life. Suffice it to say, the Big Bang has more secrets behind its inception than even the greatest minds can fathom. The reason that the galaxies are … Read more

Barred vs Unbarred Spiral Galaxies (The Differences!)

Scientists use four terms to differentiate the different types of galaxies: spiral galaxies, barred spiral galaxies, elliptical galaxies, and irregular galaxies. This article assesses the similarities and differences of the barred spiral galaxy vs. an unbarred spiral galaxy. The main difference between a barred spiral and unbarred spiral galaxy is the large bar that runs … Read more

What Is A Peculiar Galaxy? (Explained!)

A Peculiar galaxy collides, interacts, is cannibalistic, has a strange shape, or is considered diverse somehow. These are the unusual galaxies in their size, structure, and composition. They form from the interaction of two or more galaxies. Continue reading to discover the shape and composition of peculiar galaxies, how scientists first discovered these oddball formations, … Read more

Why Are Galaxies Flat? (Explained!?)

why are galaxies flat

Galaxies are flat because of their rotation. All of the stars, planets and other objects in a galaxy are rotating around the core of the said galaxy, and the conservation of angular momentum allows these objects to spread outward, but not any other direction, which is why they are flat.  There are a lot of … Read more

Spiral Galaxy vs Elliptical Galaxy (How Are They Different?)

Astronomers classify galaxies in three main categories – elliptical, spiral and irregular – with spiral and elliptical galaxies being those most observed to date. Both types of galaxy possess halos extending beyond their visible portions and both are thought to contain a supermassive black hole at their centre. Beyond shape, spiral and elliptical galaxies differ … Read more

What Is An Irregular Galaxy? (In-depth Analysis)

Galaxies are categorized using the Hubble Classification, which includes elliptical and spiral shaped galaxies. Any galaxy that does not fit into either an elliptical or spiral shape is categorized as irregular. So an irregular galaxy is one that does not have a discernible shape. But there is much more to understanding them than just this. … Read more
