Join me on an unforgettable trip filled with breathtaking auroras and exciting daytime adventures with The Northern Lights Company... -
Helio replied to the thread Does alien life need a planet to survive? Scientists propose intriguing possibility.Yes. Even if there were a rock with enough prebiotic material there must be some natural mechanism that would put things together to...

Helio reacted to Unclear Engineer's post in the thread Does alien life need a planet to survive? Scientists propose intriguing possibility with Like.
This article seems to be missing the main ingredient, which is abiogenesis and evolution. The closest if gets is assuming that life...

Helio reacted to billslugg's post in the thread SETI tests new alien-hunting strategy, but TRAPPIST-1 planets remain silent with Like.
We need radio telescopes at opposite ends of the Solar System, kept in place by optical means, the angular resolution would be incredible.

Helio replied to the thread SETI tests new alien-hunting strategy, but TRAPPIST-1 planets remain silent.But the use of arrays (interferometry) really helps.

Helio reacted to Unclear Engineer's post in the thread NASA at a crossroads:' Budget woes, aging infrastructure and hard choices ahead with Like.
This is really no surprise, given the U.S. national debt of $34 trillion and rising fast. Just the interest payments on that debt...

Helio replied to the thread The Pluto problem: Is it time to rethink our definition of a planet?.Using mass would be okay, perhaps, if it could be determined. Astronomers normally can’t determine mass but they can approximate...

Helio reacted to Mike Everman's post in the thread SETI tests new alien-hunting strategy, but TRAPPIST-1 planets remain silent with Like.
So the premise is that the folks in the Trappist system are either multi-planetary (more advanced than us, talking planet to planet), or...

Helio replied to the thread The Pluto problem: Is it time to rethink our definition of a planet?.“Eight is enough.” Physics can step in and clarify the gray areas. Jean-Luc Margot produced a paper applying physics to orbit clearing...

Helio replied to the thread SETI tests new alien-hunting strategy, but TRAPPIST-1 planets remain silent.The Trappist system has an M8V type star as the host. Red dwarfs are known for temper tantrums (large flares, etc.). The HZ here is...
