How fast is our Galaxy cluster moving?
The cosmos is a place defined by motion. For us living on Earth, accustomed to the comforting stability of our surroundi...
How fast do spiral galaxies spin?
The sheer scale of spiral galaxies means that their component stars and gas clouds are moving at astonishing velocities,...
What kind of evidence suggests that there is not much star formation happening in elliptical galaxies?
The visual contrast between different galaxy types immediately suggests differences in their current activity levels. Sp...
Which galaxy is disk-shaped?
The galaxy that most famously exhibits a distinct, flattened, disk-like shape is our own, the **Milky Way** [^3][^5][^6]...
Can elliptical galaxies be spherical?
The diversity within the universe of galaxies is staggering, ranging from the grand, pinwheeling structures of spirals t...
Are elliptical galaxies disc-shaped?
The visual representation of many galaxies, particularly our own Milky Way, immediately brings to mind a flat, spinning ...
Which type of galaxy contains mostly older stars?
When we gaze into the cosmos, the sheer variety of galaxies can seem overwhelming, but astronomers simplify this vastnes...
What is a galaxy made up of gas, dust, and stars?
Galaxies are vast, gravitationally bound systems composed of stars, stellar remnants, interstellar gas, dust, and an imp...
How many galaxies are there in the cosmos universe?
Trying to pin down the exact number of galaxies scattered across the cosmos is one of astronomy’s most humbling exercise...
