Are all galaxies moving apart?
The simple answer to whether all galaxies are moving apart is a definitive no, although the vast majority are receding f...
Are there any dead galaxies?
The universe is filled with magnificent, churning cosmic factories—galaxies actively forming billions of new stars—but a...
How does star formation differ in elliptical and spiral galaxies?
The character of a galaxy, from its shape to the color of its light, is deeply tied to its history of star formation. Wh...
Are red galaxies further away?
The light arriving at our telescopes from far-off galaxies carries a crucial message about its origin, primarily concern...
Do red galaxies exist?
The simple confirmation is that yes, red galaxies absolutely exist, and they have captivated astronomers for decades, le...
What are the properties of elliptical galaxies?
Elliptical galaxies represent a major class of stellar systems, often standing out due to their smooth, featureless ligh...
What will happen if two galaxies collide?
When two galaxies meet, the event is less of a violent crash and more of a slow, stately cosmic dance that spans hundred...
What is the main reason for the low star formation in elliptical galaxies?
The silent grandeur of **elliptical galaxies** often belies a long and dramatic history. Unlike their spiral cousins, wh...
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...
Can elliptical galaxies be spherical?
The diversity within the universe of galaxies is staggering, ranging from the grand, pinwheeling structures of spirals t...
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...
What causes open clusters?
The origin of open clusters—those scattered, relatively youthful congregations of stars—is fundamentally tied to the mas...
What are the biggest structured things in space called?
When we look up at the night sky, it seems like the stars and galaxies are scattered randomly, a beautiful, chaotic spra...
What type of galaxies have gas and dust in them?
The makeup of a galaxy—specifically, the presence or absence of the raw materials for new stars—is fundamentally tied to...
Are most galaxies red or blue-shifted?
The shift in the light emanating from distant cosmic objects tells a profound story about the structure and motion of th...
How many arms does our galaxy have?
The Milky Way galaxy, our cosmic home, is classified as a barred spiral galaxy [^3]. While that classification tells us ...
What are the three components to form a galaxy?
Galaxies are monumental stellar islands floating in the vast cosmic ocean, each containing billions of stars bound toget...
Is every galaxy a spiral?
The universe is populated by countless island universes, each containing billions of stars, and while the iconic, pinwhe...
What are the three parts of the galaxy?
A galaxy represents a colossal, gravitationally bound system containing stars, stellar remnants, interstellar gas, dust,...
Is the Milky Way a universe or galaxy?
The bright band we sometimes see arching across a truly dark night sky—the Milky Way—is one of the most recognizable cel...
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...
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]...
Are elliptical galaxies disc-shaped?
The visual representation of many galaxies, particularly our own Milky Way, immediately brings to mind a flat, spinning ...
