a large elliptical galaxy
You would least expect to find an ionization nebula in a region that lacks hot, massive stars. These stars are responsible for emitting the high-energy ultraviolet radiation needed to ionize the gas in the nebula and make it visible. Therefore, areas with mainly low-mass and old stars would be less likely to host an ionization nebula.
There are at least 20 billion lenticular galaxies in the universe.
There are at least 15 billion elliptical galaxies in the universe.
There are at least 5 billion irregular galaxies in the universe.
The Draco constellation is home to numerous galaxies, with estimates suggesting there are over 100 galaxies within its boundaries. These galaxies vary in size, shape, and distance from Earth, making Draco a rich area for astronomical study. Some notable galaxies within Draco include the Draco Dwarf Galaxy and the Tadpole Galaxy.
There at least 60 billion spiral galaxies in the universe because the spiral galaxies comprise of about 60 percent of all galaxies which are about 100 billion.
There are at least 100 billion galaxies in the observable universe, so there are at least 1.14 billion galaxies in each one of the 88 constellations in the sky.
I think the least common is elliptical or irregular..
No, because it will be impossible for the PGC catalog to have at least all 100 billion galaxies in the observable universe.
No. Because it will be impossible for astronomers to make an atlas of at least 100 billion galaxies in the observable universe.
Yes, because scientists have found hundreds and hundreds of galaxies already and scientists say that there are more galaxies out there that they haven't found!
At least 3 or 4 galaxies can be seen with the naked eye. Other galaxies can be seen if you watch through a telescope. Basically, in any direction you look, there are galaxies.
