whats wrong with the claim?
I don't understand what they mean can sustain life.
Surely there is the possibility that aliens need different conditions than us to sustain life (i.e. don't necessarily need liquid water)
Unless they obvisouly mean but in the context it's being report it sounds like they think they're may be a possibility of other life forms there.

Dibs on the big one.
Wait... There's an NSFW girly pics thread in the general?
Any people reckon this science stuff is a discovery?
Carbon based life with broadly similar requirement to life in earth is the logical place to start looking and even more likely that intelligent life will be carbon based.
And in this case they mean that the planets are rocky and are an appropriate temperature to have liquid water. We will study them to discover more but the distances involved mean that there is a limit to how much we can know about them to compare them to earth without developing fast space travel.
There's a possibility, but it's still the best signpost we have. It's a perfect working fluid for life to flourish and is abundant throughout the universe.

From this, would I be correct in saying that the Hubble space telescope allows us to look back in time?
Yep, some 11 billion plus years. The galaxy in the video is about as far back as they can look at the moment.
That's amazing to me. It's like looking at the stars allows you to time travel.
What's always fascinated me is that GN-z11 is currently at a theoretical comoving distance of 30+ billion lightyears because of the expansion of the universe, and likely no longer exists - we're quite literally staring at the ghost of something that was formed only 300-400 million years after the creation of spacetime at t=0 and in a universe than was only a few billion lightyears across (currently 100 billion lightyears across). Incredible that entire galaxies coalesced in such a short amount of time (star formation began at 100-200 million years after t=0, and proto-clusters formed much later) - especially when you consider the overall weakness of gravity in a primordial universe through the Reionization Age.
Seeing stuff as it actually happens is really a fairly localised phenomenon
Rest of the universe has some major lag issues.And to think that despite humanity's flaws, we're the only known species capable of figuring out that everything that ever existed and will exist (in our timeline) was a million quantillion times smaller than the size of a single atom in a singular moment of ∞ density and energy.
And that's just the observable bit.
Yep, there's a hypothesis that suggests the Cosmos is 250 times larger than the Hubble Volume we fixate on. Plus, what if the Big Bang was just an infinitesimally small fundamental particle in a much larger Universe-2, and Universe-2 was an infinitesimally small fundamental particle in a much larger Universe-3, and Universe-3 was an infinitesimally small fundamental particle in a much larger Universe-4...repeat till infinity in some sort of ∞ bubble/frothy sea scheme. Super disconcerting, best not to dwell upon such witchcraft.

I find the unimaginable size and scope of the cosmos to be very comforting. As we get more powerful technology, there will be lots of cool discoveries (and awesome desktop backgrounds
It's utterly fascinating and I'm glad space and spacetime is a current thing because the wonders of the universe are out there for us to see and explore, we just need to work out how.
And yet, it still begs the question, what kicked off existence? I understand that being able to look back through the universe basically gives us the timeline but I imagine we'll never find the beginning will we?

Age of an average earth-like planet - 6.4bn years
@Invictus I think about a billion years past in the time it took to scroll past that picture.

Time flies when we're having fun.
Hopefully creationism dies out soon enough. Anti intellectualism is a serious pet hate of mine.Age of an average earth-like planet - 6.4bn years

I like the Alan Guth inflationary Universe - the Universe is just a pocket universe etc.
Finding some tiny forms of life on Europa or Ganyemede would be worth it for the religious meltdown alone.
I reckon this isn't far from the truth. Nature is full of examples of fractals and this kinda thing. I wonder, if some kinda super being was looking into our universe with a microscope and looked at our sun, would it look like an exotic atom to them with the planets revolvong round the sun and the oort cloud encasing us in an outer 'shell'?Yep, there's a hypothesis that suggests the Cosmos is 250 times larger than the Hubble Volume we fixate on.

I'm waiting for us to find alien life underwater, and then it turns out to be something akin to Jar Jar Binks.
Underwater is the best place for life that we know of
Jar jar binks might be out there

What would be more interesting, finding life on Europa that has a common ancestry with Earth life, or something completely alien? I suppose the latter is always going to be more thrilling, but the the implications of the other option are also pretty great.
I don't get the fascination for finding life elsewhere. What would it accomplish, especially when you consider if it would put is in some sort of danger ?
I reckon we can take them.
It is the ultimate fascination. Probably heigthened by popular culture and scifi but everyone as a boy has glanced up at the stars and wondered.
I reckon we \ and \ or the aliens would feck up monumentally if we ever met though, we can hardly get things to work out across country borders, good fecking luck at working things out with Zorg the Squid from Proxima Centauri.

I think it's just one of those things you're either inspired by or not, it's like some people say "I don't get why we spend money on space, there's nothing there", there's no real argument you can use to convince them, they're either awed or they aren't. See also: DIY.
There is a chance, however slim, that we are the First Born and our galactic dominion awaits us.
Either would be super-exciting, to be honest - the possibility of completely alien life existing without RNA or DNA could open so many possibilities in terms of further exploration of life beyond carbon based ecosystems in Goldilock Zone planets. As for Europa, it's kinda funny in a coincidental way because we were talking about Tardigrades via PM just yesterday, and something like that is very plausible in its oceans because it is not a very complex organism and really high on the Survivability Index. Even some form of pithovirus would be a major breakthrough - though it's not nearly as exciting as more evolved sentient life
Or we establish communication and they usher us into a glorious dawn of new discoveries and prosperity.
I'm sure that's very likely.
There's a theory that if more advanced life forms exist, they would have located us by now and, as such, it's a good bet that we are the most advanced life forms in the known universe.
