Yes, lenticular galaxies are lens-shaped. They will not have spiral arms.
There are at least 20 billion lenticular galaxies in the universe.
one kind is lenticular galaxies
Elliptical galaxies, Lenticular galaxies and Irregular galaxies.
There are at least 20 billion lenticular galaxies in the observable universe, at distances up to 13 billion light years.
spiral, eliptical, cartwheel, barred spiral, and lenticular galaxies
Yes, there are some lenticular galaxies that are nearly 13 billion light years from the earth.
Spiral, elliptical, lenticular, and irregular.
There are various ways of categorising galaxies, often based on Edwin Hubble's work on the shapes galaxies. Classifications often give the four main types of galaxies as: Spiral (including barred spiral), Elliptical, Lenticular and Irregular.
That cloud is a lenticular cloud, commonly seen near mountains or hilly areas where they form in the lee of the terrain. They are associated with strong winds aloft and can indicate potential turbulence for aircraft flying nearby.
Spiral, barred spiral, lenticular, elliptical, irregular, and peculiar.
The Coma Cluster is known to contain a mix of elliptical and lenticular (S0) galaxies as its dominant types. These galaxies are characterized by their older stellar populations and lack of much ongoing star formation activity. Spirals and irregular galaxies are also present but in smaller numbers compared to elliptical and lenticular galaxies in the Coma Cluster.
A Lenticular Galaxy is a galaxy that is in between that of a elliptical and a spiral galaxy. They are disc galaxies that have used up all of their interstellar material and therefore have little, if any, star formation. They can be difficult to distinguish between elliptical galaxies if viewed side on. See related links for more information and pictorial representation
