Direct imaging of four planets 129 light years away

But as described by Jason Wang, an astronomy graduate student at the University of California, Berkeley, researchers think that the four planets may well be in resonance with each other.

In this case it’s a one-two-four-eight resonance, meaning that each planet has an orbital period in nearly precise ratio with the others in the system

wow

Awesome. Someone made the comment that is a really young star. No chance for life.

So the first planet we see is about 20 AU from that star, that's quite the distance. I'm surprised the planets show up that well in this image, must be rather large

that's some cool shite. my great great grandfather wasn't even born when that was happening.

Agree, but keep in mind that the star might also be larger and brighter than our own sun.

Edit: from the HR 8799 link in the OP:

1.5 times the Sun's mass and 4.9 times its luminosity

Lucas, go suck a dick. Your act is old.

Incredible

Man, that planet closest to the star must be on fire.


By the way, is there anyway they can calculate their distances? Like that planet that is furthest away, is that the same distance as Mercury or Venus?

So this is roughly 700+ trillion miles away?

I can't wrap my brain around how we can see that far out.

LucasP is right!!!!!!!!!!!!!
