Kepler-186f is more habitable than we thought

An extrasolar world 500 light years away could be the most promising place yet to look for alien life.
In a recent study, researchers from the Georgia Institute of Technology used computer simulations to analyze the planet's spin-axis dynamics and to determine how much its tilt changes over time.

The findings indicated that Kepler-186f's tilt is actually stable like that of the Earth, meaning that it has seasons and climates, just like our own planet does.

Discovered back in 2014, this intriguing extrasolar world is also situated in its star's habitable zone, meaning that the temperature is 'just right' for liquid water to pool on its surface.

As a possible place to look for alien life, it is certainly a tantalizing target for future observations.

"Our study is among the first to investigate climate stability of exoplanets and adds to the growing understanding of these potentially habitable nearby worlds," said study leader Gongjie Li.

"I don't think we understand enough about the origin of life to rule out the possibility of their presence on planets with irregular seasons," co-author Yutong Shan added. "Even on Earth, life is remarkably diverse and has shown incredible resilience in extraordinarily hostile environments."

"But a climatically stable planet might be a more comfortable place to start."

So how would we actually detect life there?

Apologies if this is a daft question, but why can't we point Hubble at this world and just look to see if its green/blue like earth? surely it's important enough to warrant the time.

How come Hubble's pictures of galaxies billions of light years away are so beautifully detailed, yet the pictures of Pluto, which is so much closer, are just little blobs?

Greenhouse gases?

Phone them up, see if they reply.

I don't think we could at all.Yet. But, if technology advances enough, we at least now know one great place to look.

The issue is that yes we can see into the past with our telescopes but too reach a solar system 500 miles away would mean to aim a radio telescope at that planet & send every signal possible. Afterwardswhen they recieve the signal in 500+ years we will have destroyed ourselves & they will have the space exploration technology to come & conquer us like planet of the apes reversed
