Speculative biology is simultaneously a science and form of art in which one speculates on the possibilities of life and evolution. What could the world look like if dinosaurs had never gone extinct? What could alien lifeforms look like? What kinds of plants and animals might exist in the far future? These questions and more are tackled by speculative biologists, and the Speculative Evolution welcomes all relevant ideas, inquiries, and world-building projects alike. With a member base comprising users from across the world, our community is the largest and longest-running place of gathering for speculative biologists on the web.

I don't know if this should be here but... let's start. I hope this will help those who want to create a planet capable of inhabiting life orbiting another star. And when I say "Complex" I mean Multi-cellular.

O class

Life: Negative
Complex Life: Impossible
Pros: Awesome.
Cons: Radiation, low life span doesn't give life a chance to evolve more complex life.

B class

Life: Negative
Complex Life: Impossible
Pros: A beautiful blue star, gigantic habitable zone.
Cons: Same for O class

A class

Life: Thin possibility
Complex Life: Very rare (except when it comes to Eo :) ... or is it?)
Pros: Good whitish color and a spacious habitable zone.
Cons: Gas giants likely to form around these stars (no terrestrials :( ), short lifespan, radiation.

F class

Life: Possible
Complex Life: Very rare (except for Darwin IV :) )
Pros: Close to sun like stars
Cons: Radiation

G class

Life: Absolutely
Complex Life: YOU DON'T SAY (this means possible :) )
Pros: Very long life span, enough for life to develop into complex life, good stellar flux.
Cons: AND HIS NAME WAS JOHN CENAAAAAAAAAA... Just kidding, thinner habitable zone than those of the O, B, and A stars.

K class (dwarf)

Life: Possible
Complex Life: Possible
Pros: Most common type of stars in the galaxy, if not, in the Universe, low radiation, very very VERY long lifespan.
Cons: Smaller habitable zone (to be verified), higher chance of tidally locked planets, which might not really help at the development of stars, high stellar variation, low stellar flux.

M class (dwarf)

Life: Possible
Complex Life: Possible
Pros: VERY common in the Universe. Same pros like the K stars.
Cons: Tidal locking very common, lower stellar flux, low energy for life.

Neutron/Pulsar

Life: Nope
Complex Life: Oh Hell NO!
Pros: um...
Cons: Radiation, radiation, radiation and radiation (this means that this star generates high dose of radiation, even worse than O, B, A and F stars).

Black Holes

Life: Forget about it
Complex Life: Posted Image
Pros: really?
Cons: Gamma radiation, no light, accretion disc likely to destroy planet (except Gargantua... ok that's the last time I'll do the "except" thingy), no such planet like Miller's would exist!

This is a little comic I know. Alright, so after that, it seems that the best options are F (maybe), G, K and M stars.

Hope this MIGHT help ;)
