Oxygen molecules been found in space

[Tsanten Eywa 'eveng]

for the first time, in the history, has it been found oxygen molecules to form life been found out in space, in Orion Nebula:

Orion Nebula has a distance of about 1500 light years from Earth

This is just wrong...

One of the reasons I hate space.com. This is nothing new. Oxygen is everywhere! For example, most old stars have some oxygen in them. Planets usually collect some oxygen, more or less. Molten rocky planets constantly give off oxygen!

excuse me, it depends on the temperature on the planet, is it too cold, no oxygen exist, even if it is too hot, because the planet is then inhospitable for life. If life is going to exist, it must be oxygen. Oxygen is very important, and as I know, is it oxygen in water

a planet to have life on need:
stable temperature and a stable atmosphere
water on the surface
oxygen
vegetation(I think)
size of planet, is it too big, is it too much pressure

Oxygen is actually a poison a lot of life.

this happened 2.4 billion years ago, can it happen again?

Oxygen does not depend on the temperature. Heard of liquid oxygen?  And there is a very thin oxygen atmosphere around Ganymede!

Water does depend on the temperature, but oxygen, as a gas, is pretty independent of temperature.

If that, only life can form in the sky, or they will freeze or be heated to death

Life needs much more than oxygen.

What I said is that oxygen is everywhere and oxygen != life.
