I doubt Mankind will ever stand on another world outside our system. 40 light years is just unreachable. A radio signal one way is 40 years, a currant space craft trip about a million years one way.

Interesting

An interesting system
As usual the alien life brigade is out

Relevant points
Planets will be tidally locked with very short periods
Large flares are common in small mass stars

Probable life: Close to Zero

Apparently Pluto was somewhat dejected by the news, hoping it too might make the cut.

In news on another front, apparently there is a group working on a new/different definition of "planet" which if accepted would help Pluto rejoin the planets.

Best

... and yet, we've been shown ad infinitum:

- What we find out there is always more spectacular than our widest dreams
- The impossible becomes common place as our knowledge grows.
- There are candidate sites for life in our solar system where we never expected to find them.
- Where life can exist, it will exist, even in a melted nuclear reactor core.

...based on these titbits, I'd be amazed if there were not life in this system if its as diverse and complex as so far hinted.

If they've been picking up our TV signals they've been watching such gems as Grease and the Brady Bunch.

Hopefully they'll conclude there is no intelligent life here ...

Hi Wavy.
I think about 30 yrs ago they got some signals from our ol mate ADOLF'S first harangues!
IN 40YRS TIME it will be DONNY'S broadcasts! They won't be visiting any time soon I feel. Haw!!!
bigjoe!

All too true I agree!!
Its good speculation though , just to give whole ASTRO
THING momentum!

This speculation of advanced life has about the same likelihood of being correct as the 1800s predictions that Venus has lush tropical forests and dinosaurs did.

But multiply a near-zero probability on any given planet or moon, by the hundreds of billions of galaxies in the universe, each of which typically has tens to hundreds of billions of stars (most of which seem to have planetary systems), and account for the dozens of moons that each planetary system contains (and a not-insignificant fraction of those moons now seem likely to have the conditions to support life) and you get a near certainty ...

I was listening to the Radio about this ... a NASA ( in Canberra - CSIRO ) spokesman said it was 39million light years away.

He goes on to say, using the fastest Rocket / Space Graft we have ( Current Day Technology )..... which travels at 17klm's per second, it would still take 750,000 years to reach it.

Good Luck with that .....

Not in our time anyway ....

At that speed it would take 76,764 years to reach Alpha Centauri.

Light speed = 300,000Km/sec divide by rocket speed of 17Km/sec = 17,647 x 4.35 light years dist to Alpha Cent = 76,764 years.

We need Cochrane to hurry up and build his warp drive.

"New Planets"? That's false advertising! They're actually slightly used planets in very good condition.

Seriously, though, it's an exciting discovery. No-one on this forum today will live to see them explored, but it's a nice thought that, someday, humankind could send a mission there even if it's only robotic.

But yeah, warp drive is sorely needed: who wants to help get a Kickstarter up and running ...

It's a mute point but with gravity assists we can get way faster than 17k/s. here's an excerpt from the Broadsound Bulletin

'The fastest man made craft I can search is ESA's Rosetta. As comet 67P G-C swoops in towards the sun it will travel at as much as 37.5 km/sec = 0.0125% of speed of light, and Rosetta is orbiting the sun with the comet. At that speed the run from Carmila to Sarina or to St Lawrence would take 2 seconds and to Proxima Centuri (the next nearest star to us after the sun) would take 32,000 years.' (i hope the maths is good??)

also as pointed out to me once before in a similar thread - slowing down at the other end is an issue.

i find the approaching proof of life existing some/any where off Earth very exciting - it will be as significant as Galileo's proof 400 years ago that the universe doesn't orbit Earth.
The space and Earth telescopes now being built will be able to study these and other closer planets' (discovered because we no longer rely on transiting orientations) atmospheres, and NASA is starting the process to probe Europa for life around 2030.

Your welcome guys not a problem for posting. Thanks Shiraz for posting as well.

I think it's a moot point whether we can travel to these systems or there may be advanced life there. But who knows if our civilizations survive we may be able to achieve and answer those questions. For me just knowing that these new worlds ( or perhaps slightly used worlds ) exist and there could be similar to ours makes it mind boggling enough. This was one common dwarf star that was studied for 500 hrs, imagine how many of these worlds might possibly be out there.........

I wonder if my Dobsonian will help me find some!

Cheers Julian
