Can life form in Elliptical and Irregular galaxies?

Answer 1

Yes, in principle life can form on any suitable planet.

The only event that could impact life is if a star goes supernova within ten light years; the radiation from the explosion could wipe out all forms of life. Stars in all forms of galaxies are fairly well separated, with the possible exception of the galactic center.

A planet with the proper composition of chemical elements and the appropriate distance from a main sequence star are the prerequisites for life as we know it.

Life can flourish as long as the star of the planet supporting it is not within 10 light years of a star that could go supernova.

Indeed, elliptical and irregular galaxies have the potential to produce life, but spiral galaxies, like the Milky Way, are thought to be more conducive because of their higher metallicity and stable environments.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
