My mind is read to be expanded by the Cosmos. Don't let me down NASA.
Neil deGrasse Tyson was on Joe Rogan's podcast earlier today, it was actually a pretty good sit down and talk.

We can see big ones if we blot out the star's light, and we haven't even launched James Webb yet.

What we hope it is: "We found signs of advanced life on another planet"
What it will be: We discovered a way to possibly have a 5% better chance at seeing if a planet has red or brown dirt.

Just a FYI, Belgian national tv (VRT) also talkes about the 7 planets. Article is in dutch:

Close enough - it's we found seven.

"We found a planet with similar conditions to Earth with the potential for life, which is X light years away. We're going to continue to look at it from this distance with a telescope and hundreds/thousands of years from now we might be able to visit it."

They appear to be 7 earth like planets orbiting a single star nearby our solar system.

Well the first exoplanet was discovered only 15 years ago. Lots happening right now it seems. Who knows what we will find in the next 15.
Its the ability to find signs of life in the atmosphere that they think they will soon be able to detect (if there is any) that has me most excited.
Thats like the big event I want to witness in my lifetime.

I feel like I've seen this sort of hype from NASA before.
Sounds plausible, since Michael Gillon will be speaking, he manages the TRAPPIST project. Awesome name by the way; can't go wrong with beer.

We basically know what it is... And it's pretty spectacular.
listening now
Seven planets in the Goldilocks zone? That's nuts!
Imagine if the international space station was actually an interplanetary one! Interplanetary internet!
As always, humanity stays losing. We could have up to six sexy alien neighbourinos, but nooooooooo, we had to settle for this stupid Sol system with nothing but rocks and a star that will eventually roast all of us. Bah. Bah I say.

The line is "A white hole?"
Geez, NASA has more eurofriendly pressconferences than Sony.

Guna have to get some sleep before the press conference so I can speculate all day tomorrow/today about aliems.
They actually talk about the news conference as well.

A white hole?
This thread started with a Red Dwarf reference and first reply nailed it.
Thank you both.

It takes the planet 7 years to move 1/10th around the star?
those are huge planets with huge orbits
for instance: the orbit of Saturn is 29 Earth-years, and Neptune has an orbit of 165 Earth-years.
Nothing crazy about that. The gas giants in our solar system have orbital periods of 12, 30, 84, and 165 years. Pluto is at 248 and Planet 9 (if it exists) has an orbital period of 10-20 thousand years.

7 planets!!!!! Holy shit this is awesome!

7 potentially habitable planets.
39 light years away.
That's only 370,500,000,000,000 km away
That's only travelling 299,792 kilometers per second for 39.29 years
The fastest receeding spacecraft at the moment is Voyager 1, which is exiting the solar system at 62,000kmh which would take nearly 700,000 years to reach that far.

is the stream already started? Where are people getting this information from?
Yeah thats why you use light and block out your star in a pattern that could only be interpreted as a signal from a higher intelligence

In truth there are so many factors at stake.
We can't possibly detect the gravitational field on those planets so we don't have any idea about the effects of gravitational time dilation. Time could be passing 20x faster on their planet.
We haven't even taken into account the fact it takes 39 light years for the light of their sun to reach us meaning that we are effectively seeing a long time into the past AKA what those planets were like at the time the light from their sun was radiated out.
That means even if we drastically increase our highest receeding speed - we could arrive to find the situation on those planets vastly different - rendering their discovery even more insignificant at large. Hell - even if we invented cryosleep or FTL travel or whatever - we could arrive to find the star dead and a black hole in it's place.

39 years. "light years" is a measure of distance, not time
39 years isn't all that long.
We can accurately predict what will happen to a star in a 39-year period.
And we could definitely extrapolate whether or not this has any probability of happening given a fairly short time range.

I predict that life is abundant in the universe. I'm 33; give me proof before I die please.
It is distance and time.
It is distance and time.
I heard an estimate it would only take 20 years to reach the nearest star using a Solar Sail method, but the hard part is then slowing down at the other end.

In the same way that saying "10 leagues per hour" is.
It doesn't communicate anything different, and is just redundant.

So the official story drop in about three hours right?
This new fancy telescope that is going up in late 2018, anyone in the know, what kind if any new information could be discovered then about the planets?
Or is it an completely different set of tools that is used to "see"/detect planets?

Of course. I mean, if light entered a black hole and came out of a white hole trillions of miles away, the distance that beam of light would travel in a year would be much further than a beam of light that didn't have such a passage.
And, likewise, an expanding or contracting universe has an impact on this as well.
As does passing near/through gravity wells.
Still, I'm not aware of any SI usage of the term "light year" in which it refers to something other than distance.

A Light Year;
A unit of astronomical distance equivalent to the distance that light travels in one year, which is 9.4607 × 1012 km
Therefore it is distance AND speed when used in different contexts.
It's the use of speed over time to equal distance.

Well, it's more like it is short hand for a distance.
Light travels at 9.46*10^12 km/year.
When you take Light years, the units are (year)*(9.46*10^12 km/year) and so you are left with distance, in this case km.
