I don't think that's correct. In the report they give a maximum temperature that life can survive on Earth and it's not much more than the boiling point of water (120c or so)

Interestingly, the atmosphere on Venus consists of mainly carbon dioxide with clouds of sulfuric acid and nitrogen. The temperature at the equator is about 450 degrees (lead melts at 350). The atmospheric pressure is far heavier than earth - 90 times heavier. The planet surface is either flat, devoid of any liquid or covered in volcanoes, ranging from half a mile to well over one hundred miles wide. The lava flows from these volcanoes can stretch for thousands of miles.
Hurricane force winds constantly smash the atmosphere around and science dudes have been tracking a massive cyclone for about a decade so far - god knows what they've named it. That said, the surface winds are much calmer, weirdly.
The day/night cycle is over one hundred days long, so after you've seen one sunrise, you've got a third of an Earth year before you see light again. Assuming you don't count the light cast from your burning children, homes, possessions and lead store. In Latin, the planet Venus is referred to as Lucifer.
This hellish place is where women come from.
This has been my overriding thought for as many years as I care to remember.
The question should surely be - what is life? It could take many shapes and forms and not necessarily dependent on the presence of water. These alien life forms could exist on nuclear fusion or concentrated hydrochloric acid.

Meanwhile on earth:
Scientists have detected an atmosphere around Selhurst Park for the first time.
Their observations suggest that Selhurst park is cloaked in a thick layer of gasses that are either Body odour or Methane or a mixture of both.

Wouldn't happen in Alpha Centauri.
Well, whilst I agree that the definition of "life" is a debatable one and one that has vexed philosophers for centuries, the chemical basis for life is on amore certain footing.
Carbon is generally considered to be the best element from which to construct complex structures. it has a valency of 4 and is small enough to be able to create very long chain, off which other elements can then attach to and create said complex structures. Other elements either don't form as many bonds or, like silicon (directly below carbon in the periodic table) can, but are too heavy to form long chains like carbon, thus reducing the scope for complexity.
Oxygen is light, highly reactive element and in molecular form can store lots of energy as it forms double bonds. It is also in water molecules and because of its valency of 2 forces the hydrogen atoms to attach at a 120 degree angle. This then allows water to have the properties it does and make the molecule highly dipole, which makes water such a good substance in which to conduct chemical reactions.
In other words, the basic chemistry of life is probably going to be variations on these common themes. How that then manifests itself as actual thinking, living sentient beings is entirely different, all due to the complexity afforded by this fundamental chemistry.
The Interstellar medium, or interstellar space. The ISM (did this at Uni) is the space within a galaxy where no stellar influence dominates, either through magnetic fields, solar wind, gravity etc. It's the place of dust clouds, galactic magnetic fields and detritus spat out from stellar environments. For Voyager, it just so happens that the next stellar system it will meet is like 300,000 light years away. That's not the closest though.

They could be fibbing.
There's probably a planet up there with alien dudes in shades, shorts and flip-flops thinking that no one can survive in windy, grey, drizzly 8 degrees.
Voyager is in the Delta Quadrant

I think its just because we have a limited frame of reference. Ie we know the conditions that support life on this planet and can reasonably assume that those would be the minimum conditions elsewhere.
That's not to say that life can't thrive in conditions that we, or anything we know of, simply cannot. Maybe that planet plays host to a race of bipedal fire people.

strong and stable with me, or...
You can follow how far the Voyager probes are here.
Voyager 1 is in interstellar space, and there is a mind boggling amount of that before it gets anywhere near another solar system. Voyager 2 is in the heliosheath which is the outermost part of the heliosphere where the solar winds from our Sun are slowed by the interstella medium. Voyager 1 is currently travelling at 38,000mph.
Both probes were built to last 4 years, and yet to date it seems all the instruments on board still work. There is a brilliant documentary about the probes on BBC iPlayer I think.
