Also probably should note when talking about Eta carinae about the supernovae impostor event of the 1800's where observations from 1827 1845 known as the great eruption where it peaked at around -1 apparent magnitude before declining drastically due to the rapid cooling of the refractory component of the ejected material blocking the majority of the stars light lowering it to magnitude 7.6 at its lowest before gradually returning to 4th magnitude in the late 20th to 21st centuries (with several much smaller erratic outbursts that reverted on mush shorter timescales). Note that without the obscuring dust nebulae of past ejections the more massive of the pair of stars would be about 1.5 magnitude from Earth so definitely would be optically visible provided one is in the southern hemisphere to see the star. Some other relevant stars which could go boom soon astronomically speaking is Antares which is ared supergiant around 550 light years away. Also another relatively "soonish" supernovae candidate is the central star of IRAS 00500+6713 which is itself a supernovae remnant from SN 1181 a rare type Iax supernovae event which is a special variant of a type Ia supernovae where the progenitor star isn't totally destroyed. In this case the merger was between a massive Carbon Oxygen white dwarf and a high mass Oxygen Neon white dwarf which managed to together to be just massive enough to reestablish hydrostatic equilibrium between runaway fusion and gravity. The resulting object weighs more than 1.5 solar masses and can only sustain itself though its runaway fusion reactions for somewhere less than 10,000 years at which point it will have to undergo a core collapse supernovae. The luminosity estimate tells us a minimum mass but still has some range of variability so the more massive the merger product remnant the sooner the star goes boom again. As a run away fusion product the stars spectrum is also quite bizarre dominated by elements like Neon Magnesium Sulfur and Silicon.

Ever since I was a kid watching Stargate SG-1, I've always remembered an early episode when this exchange took place: Carter: "That means something inside this pyramid is slowing down neutrinos. Normally, neutrinos pass right through ordinary matter, no matter how dense. I mean, something like 500 million billion just passed through you." O'Neill: "No matter how dense, huh?" (a few minutes later) O'Neill (to Daniel Jackson): Hey, if you'd been listening you'd know that Nintendos pass through everything." Jackson: "I've heard." O'Neill: "Everything..." I love that show, and I'm always happy to see little bits of accurate scientific jargon in Sci-Fi. Stargate gave me my love of all thing science & astronomy. The fact that neutrinos rip away the outer layers of a star during a supernova is that much more insane, knowing how they typically don't interact with matter. Really makes you think about the shear energy behind these events. A particle that basically phases through matter is excited to the point that it rips apart a star is mind-blowing.

Mass extinctions should be visible in the evolutionary record as well. Since it would have been peculiar features that determined what survived and what died when the environment suddenly shifted, it seems likely to me that there would have been relatively few who had a genetic disposition to relatively unforeseeable circumstances. I imagine it was likely a useless chance mutation until rather suddenly it was the only way to survive. Like the forking of a root growing from the depths of the sea, reaching endlessly into the unknown.

I love these videos, but I have to say, there is something weird with sound/voice compression on youtube. I started noticing, a few weeks ago, some distortions in the voice, and weird stereo panning (checked it on audacity sound editor, and both android/windows devices). If you use headphones it gets worst. It is happening in lots of videos, not only here.

Oh, dear. You have succumbed to some Bad Astronomy. The supernova in the animation at the beginning should have been crossing the sky along with all the background stars as the Earth rotated. Whatever its proper motion, it would be too slow to observe with the unaided eye over a timescale of mere days. And if it's more than 20 light-years distant, it would have to be moving at unfeasible speed to appear to hang stationary in the sky like that.

In the death throes of a dying star on its way to becoming a neutron star or black hole, they're produced in such insanely prodigious quantities that the rare probability of interaction with all the light elements in the outer shell becomes an inevitability. It's actually kind of wild. There are several waves of neutrino interaction in the forms of "swells" that create a physical pressure that expands the core's material before gravity pulls it back in again and restarts the cycle. It's actually so spectacularly balanced, I actually kind of think of it as one of these more overlooked "fine tuning" arrangements. These erstwhile almost useless, very confusing particles have one of the most important roles to play in not just stellar evolution, but cosmological evolution. Think about it. If neutrinos were perfectly neutral, there would not BE all the rich heavy elemental star stuff around to build US.

I’ve always thought about this and have even had a reoccurring nightmare where the sky looked like a supernova and everything felt soooooo heavy and it was the most intense fear, so much so I couldn’t move, like forced falling, -10gs in your gut and chest. The dream always started and ended the same. And I think it has to do with something I saw when I was younger…

It does help to be able to add together small clues. Quite often there's a number of puzzle pieces that come together to form a larger picture. This is how, for example, we can distinguish astronomical iridium from that generated in volcanic eruptions.

Recently published paper (not yet peer reviewed), modeled the evolution of Betelgeuse and compared the results to our observations of that star and predicted we may see it supernova on a timescale of less than ~150 years, perhaps within 10 years. I don’t remember the exact limits of the range that best fit their model to our observations, but those are roughly the range if I recall correctly. Seems we may be closer to seeing it than previously estimated.

@garethdean6382

They are emitted first. The hot plasma of the supernova absorbs and scatters light; photons have to follow a long, random path to get through. Neutrinos can pass right through and so get out a few seconds earlier.

On practical physics, static just means being held in place by opposing forces, it doesn't mean forever . A traffic cone standing on a busy street to warn about a pothole is a static object as it is held in place by the opposing forces of gravity, internal solidity and sideways friction against the pavement .
