"To find alien life, we should focus on white dwarf stars" Topic

"Humans have been searching for signs of extraterrestrial (ET) life for decades. We've been listening carefully for strange radio signals, looking for signatures of the artificial altering of stars and digging up rocks on Mars. But alas, so far, we've found nothing. As far as we can tell, we're alone. But it could be that we're looking in the wrong places.

We know that life can appear around stars like our sun, and we know that stars like our sun will turn into white dwarfs (small, dense stars that are stellar core remnants approximately the size of planets) at the end of their lives. So, perhaps we should be focusing our search around white dwarfs…"

Interesting – there was a conjecture that long-lived red dwarfs or red stars in general were good candidates for life as well: long term stability, low UV and other harmful radiations and a tendency to produce infra- red heat more than light.
This seems reasonable, but one wonders about long-term viability of life on worlds of such stars, given the white dwarf tendency to have high UV emissions.

Interesting indeed….
