1) Empty space has no heat; only the background radiation and the heated matter in it. An individual atom can be very hot; it certainly would be starting its life inside a super nova. But because there's no air blowing on it (convection) and there are no cooler atoms touching it (conduction,) it stays hot; it doesn't lose its heat. 2) It's a 'bubble.' Think of an explosion. The material starts at a central point and flies outward. The interior of the bubble is essentially empty. If you are an observer in space, the edge of the bubble would approach you and then pass you. As it expands, it gets thinner and thinner. A few million very hot atoms impacting the Earth would have very little effect. And once the bubble passed us, the surrounding space would returns to it's near absolute zero temperature.

Does this mean that life on earth evolved only under these special, out of the ordinary conditions? Does this have implications for the probability of finding life in other solar systems?
There's no indication that the conditions here are special or out of the ordinary. It's just the anthropocentric view that because we're here, this is a special place The rational view is that this place is ordinary and we, as ordinary living creatures, just happen to be here. We don't have detailed direct observations of other planets, so it's still possible that there is something extraordinary about our region of space, but there is no evidence so far, so there's no reason to assume that it is.
***** It's like a 'rule' of unusual events that if you search long enough for them you will find one. Also there are various types of properties not every solar system will have, but most || many will have one of them.
At 10 million years ago, life was very advanced. The dinosaurs perished at 65 million years ago. The real question would be what effect did it have on Earth, in terms of climate and also biology - evolution.
Would the supernovae influence the life on the planet in any way via the peanut shaped cloud? It seems amazing to me that the greatest explorers of our history are just scientists in a lab, such an interesting discovery.

***** - That is Funny! Since good ole Phil uses the word probably all throughout the article, it shows he has no idea. At the end of the article he even admits there is no way to predict when a Supernova will occur; therefore even though it is moving away from us it could blow at anytime. They can say a million years from now or whatever guess they want, but the Truth is they do not know.
***** - Plus since we are detecting invisible Diamond Stars - aka cold white Dwarfs, you can't discount anything. There could be a closer hidden potential for a Supernova in our backyard, but we just haven't found it yet. public.nrao.edu/news/pressreleases/cold-white-dwarf
***** - Thanks for proving my point! We have a long way to go before we fully understand solar dynamics. For all we know it could have already went Supernova and the light hasn't reached us yet.
40% of the X-rays are present interactions and 60% are past interactions from supernovas. Still does not answer the question "Can solar wind create a bubble without the help of supernovas?"
MerciaKitsune question can be answered by an expert I recall in a higher ed place. The notion of temperature is a notion of rapid high movements of particles and not requiring the density to pressurise them apparently. Guess the experts should be sought after afore I lose my confidence in science as much.
Yula Kharina comment makes me ponder that the rocks in our solar forming region must have come from another exploding star system with planet(s)like ours;worth thinking of alongside.Guess another think tank is to arrive given time.
Nobody can know that yet. It'll take a very long time before we do. We do know, though, that there was abundant life on Earth when those supernovae blew up, and that life on Earth was NOT eradicated. So the stars that blew up were not near enough to incinerate the planet. The rest is still in the "question-mark" stage. Yet to be learned.
well if space is moving from east to west I guess it would be a supernova most probable. lol Do we know in which direction space travels? Talking about newer galaxies are born in one area vs looking in another direction and the larger or older galaxies.
No. We could pass right through that hot gas and feel nothing. Why? Because a gas with only one atom per liter of space is too little to be felt, no matter how hot it is. You're thinking in terrestrial terms, not cosmic. That liter of space is COLD. There is no air to diffuse the heat from one atom throughout that empty cold space.
fastermx thanks for the reply. but may i continue and ask whether the massive speed of a space craft through this space, wont accumulate by the friction between this sporadic super tiny hot particles for creating any hitting effect? i mean because of the enormous speed of a space craft that will pass through it wont it condensate those spreaded particles into hit?
Holy shit! I thought the solar system developed from a spiraling gas cloud when a nearby supernova compressed the system ... to find out that that supernova was actually more likely a cluster of supernovas which were a lot closer to home and left behind a super-hot low-density bubble around our local space is series of disturbing thoughts. Why isn't this discovery discussed more? PS, +1 subscriber.
CR Opportunity - Great observation - they definitely could have spurred our imagination - Check out this Supernova at 11.5 million light years away. www.esa.int/Our_Activities/Space_Science/Integral_catches_dead_star_exploding_in_a_blaze_of_glory
CR Opportunity More likely the gamma radiation received on this planet mutated our ancestors into a new pathway to us. 10 million years ago is just about right.
Something bothering me lately: A supernova is caused by lack of fusible elements such as Hydrogen to Silicon in a star to keep fusing into heavier elements right? Well if all the Hydrogen was used up, how does the area of the past supernova have enough hydrogen left for our Sun to even form? Shouldn't it have all been used up and fused into helium and heavier elements? Do the surrounding elements left-over have enough time to decay back into hydrogen for the process to restart in the same place?

Truth Seeker Horrible cite to a website that seems to go out of its way to hide the sources of its information. Oh, and no, the formation of organic molecules has nothing to do with the distribution of hydrogen after a supernova. That's your basic spooky woo-woo talk.

***** Not quite. A supernova is a gravity event, while a fission bomb (it makes lighter elements, so it's not fusion) is a concentrated decay event. A fusion bomb is more like our sun, in that it slams together hydrogen to form helium, but much more efficient then the sun. (The energy output of the sun is comparable to that of a beetle, I believe. There's just a lot more sun then there is beetle, so the sun wins on quantity :D)
Please visit Zooniverse, there's a science project on these bubbles, to which you can participate. There are many other projects you can also contribute to eg. NEO's or CME's. It's a citizen science portal, please contribute. Thanks.
Sorry, but I'm calling bullshit on the 1 million degrees hot thing. First of all, you said we're inside this bubble. Last time I checked it isn't 1 million degrees outside. Also, 1 atom per 0.001 cubic centimeters? Don't atoms need to run into each other to produce what we know as "heat"? Generally the less pressure, the less heat. Also, the surface of the sun is only a few thousand degrees. You're trying to tell me the space around us "filled with almost nothing" is 20 times (or more) hotter than that? Bullshit. Just because someone observes some background radiation around us doesn't mean it's time to draw some fantastical conclusions out of thin air despite all (other) evidence to the contrary. In short, citation needed.
You truly do NOT understand much about the science involved. You draw your conclusions from your own experiences in Earth's environment, and assume that what applies on Earth applies everywhere. Space is VERY different. An atom that is a million degrees could touch you and you'd feel nothing, even on Earth. But on Earth, that ONE atom's heat would quickly dissipate among the atoms all around you. In space, it can't dissipate to anywhere. So the atom stays hot. You could only be burned by it in space if googobs of hot atoms hit you at once. If you were exposed to the temperature of space where one atom per liter of emptiness was a million degrees, you'd still freeze. There is nothing shameful in being ignorant. Ignorance is very curable, and the cure can even be fun. But to apply your ignorance to reject things you know nothing about, and claim to know better, is pure arrogance. I'm not going to educate you. If you really want to know how those atoms can be a million degrees, dig out the information for yourself. It's what I've had to do. You presume to know more than the scientists do, without even TRYING to understand what they are saying. That's not normal, innocent ignorance. It's being "ignorant-and-proud." Which IS shameful.
fastermx "Hot atoms"? Sounds like I'm not the only one who needs a science lesson. Atoms don't have temperature. Heat comes from billions upon billions of molecules vibrating and bouncing off each other. The energy from such collisions/vibrations is released as heat. The individual atoms themselves have no temperature. Also, that whole thing about applying "earth physics" to space is complete bunk; physics are physics and they are the same across the entire universe, otherwise the universe would not exist.
Jokers- 'charge exchange' lol what ever next? They are just trying to admit that that there is some form of electricity in space whilst trying to totally ignore the fact that we live an Electric Universe rather than a mechanistic one as believed in by scientism. These people should really go back to school and study electrical engineering and plasma physics.
glorys9 - That's not true. There were many ancient civilizations that were quite knowledgeable about astronomy. Most were in Asia and Africa. Then, later in the Americas.
