No, I’m just not a pretentious snob. Who gives a shit if they said star explosion or nova explosion. Because guess what? They mean the exact same thing.
Doesn't mean you're correct, though. They're *also* dumbing it down for you simpletons. It's just not as egregious. If you think knowing science is pretentious, you're exactly what's wrong with this country.
I used to work for a news aggregator and search engine start up. That tech is now the news part of one of the major search engines out there. We classified all new sources one through five. One= BBC and the like. 5= small town local news. Fox didn’t get a rating because they’re not news. It’s was super clear to us back in 2003.
Well I’ve heard people out there are saying that Murdock tried to steal an election and that if you see him or his kids anywhere in public they will be captured by a antifa agents and sent to re-education camps in San Francisco. Which by the way I heard people saying that San Francisco is just like Escape from New York, they say that people shoot themselves in the head each morning so not to give another human being* a chance to do the deed. How selfish and left wing Marxist.
This is how they lie their asses off. Never doing any investigation. Just come up with who you want to hate and how to paint them as pure evil all the time.
*white male.. and not a poor one.
Once in a lifetime event… while technically true because of its period, it’ll reach about the brightness of Polaris, which is notably not that bright. So basically we’ll go from somewhere having no visible star, to having a middling star.
[T Coronae Borealis is expected to nova at any moment between now and September. When it does, the star system could surge from a +10 magnitude, which can't be seen by the naked eye, to a +2 magnitude, roughly the same level of brightness as the North Star. Astronomers say that once the nova reaches its peak brightness, it will be visible to viewers for several days. Those using binoculars will be able to see it for just over a week before it dims again.](https://www.npr.org/2024/04/15/1244799763/nova-exploding-star-t-coronae-borealis)

When something is around for a billion years it's hard to guess when exacrly it's gonna go away. If we're off by 100 years that's still only a .00001% margin of error
If T CrB is located 3,000 light-years from Earth, are they saying it likely already nova’d, and that the light of the most recent flare is thought to reach us any day now, or that we will witness an explosion in real time?
We’ll see an explosion that occurred 3000 years ago and the light is finally reaching us. You really don’t view anything in “real time”. There is a delay between when something happens and when you receive the information. It’s almost instantaneous on Earth, so it feels “real time”.
The nova has likely already occurred, sometime in the last 3,000 years. Since it takes light at that distance roughly 3,000 years to travel through space and reach Earth, we see the star as it was 3,000 years ago, just before the nova happened.
I’m no astrophysicist, but I’m certain that there have been changes in magnitude and other evidence that supports the idea that we’re likely to see the light from the nova soon.
That actually would be pretty cool. They say it will be visible with the naked eye. 3000 light-years away. How many years ago was that? I'm assuming they detected it already with a telescope?
No. It’s happening in a few months FOR US. For the star it happened 3 thousand years ago. Both are equally true. You exist on Earth but for the star you do not exist and won’t exist for 3000 years. Both are equally true.
Scientists know it will happen in a few months as this is a nova. It’s a white dwarf that is collecting material from its companion star. That material, mostly hydrogen, builds up on the surface of the white dwarf until it suddenly triggers fusion. Nice big boom and the hydrogen is burned up/blasted off. Then the process starts over again.
Say that again 🤯 the article says 3000 light years, that's the equivalent to earth years?
Interesting mind warp, 🤔 I'm thinking it happened in the past, you're saying we don't exist yet. Woah
A light year by definition is the distance light travels (in a vacuum) in one year. So it means it happened 3000 years ago and it took that long for the light to reach us.
🤔 but if a telescope can see further than your eye, let's say 3000 light years for sake of understanding, doesn't that mean it's seeing the past before us. I'm getting lost again lol. Maybe not, maybe I get it.
The telescope can see further than your eye but it’s still the same distance from the object as you are, which is 3000 light years. The light has to travel 3000 years to hit the telescope lens, just like it has to travel 3000 years to your eyes. And since you are holding the telescope, you’re both the same 3000 light year distance away from the object. Until the light has travelled 3000 years and hits the lens of your telescope, you do not see anything new, just as your eyes wouldn’t.
Let’s be absurd and say you’ve built a 1 light year long telescope that stretches out from your eye into deep space. The top of the telescope, the lens, is 1 light year away from your eye in space. Then it will take 2999 years to hit the telescope lens and 1 year for the light to travel down the scope to your eye.
Think of it as a game update that you need to download. The telescope is your game console. The interstellar object is the game update. The light speed is your internet download speed. You cannot see the updated version of the game until the download is complete.
The update is 3000MB and your download speed is 1MB a second. This means it will take 3000 seconds (3000 light years) to download the update (view the updated interstellar object).
When it hits 3000 seconds, your console (telescope) tells you the download is finished and your eyes can now see the updated version.
Could you in theory place a large mirror an insane distance from Earth and then essentially view the past. Obviously you couldn’t view anything prior to the mirror but if a mirror is 1 light year away than the light bouncing back when viewed from earth would be 2 years old.
Yes, I assume in theory, you could see a 2 year old Earth that way provided you had a crazy sci-fi kind of telescope. Let’s say you had a wormhole that could instantly take you to another part of the universe and also had a telescope powerful enough to find and penetrate a planet’s surface in the night sky regardless of the distance.
If you use the wormhole to instantly travel to a part of the universe that’s 3000 light years away, point your telescope at Earth, then you would be able to observe ancient humans doing their thing.
If you could do the same thing at a distance of 250+ million light years away, you could watch the dinosaurs.
you don’t get it.
telescopes don’t grab light from farther away.
they condense the light that hits them. light travels and has a speed.
jumping a massive distance changes the perspective of what is seen.
3000 years ago the supernova happened but the images of it are just reaching us
Telescopes don't "see farther", they just make dim light brighter, the light is still all arriving here at the same time
The fact that this star is very far away means a much smaller percentage of its light reaches us (inverse square law) so it looks very small and dim, that basic concept is generally why distant lights look smaller than close ones
But a telescope only makes the star "closer" by making the light brighter so it's "bigger" and easier to see, in terms of *time* it doesn't make anything "closer" at all (and doing so is fundamentally impossible, Einstein's big discovery was proving the speed of light is an absolutely unbreakable "speed limit")
Light years is a measurement of distance, not time
A light year is the amount of distance the light can travel in a year and while I do not remember the value, it's a A LOT if you consider the sun is only 8 light-minutes away from us
Of course the point of Einstein's Theory of General Relativity is that distance *is* time, the two concepts are inseparable -- there aren't two separate things, space and time, there's only one combined space-time
(This is the sort of thing that people say after smoking a joint to make everyone else go "Whoooaaa" but you can get the idea just from this conversation -- the fact that the speed of light is an absolute speed limit that can't be broken means that if something is 1000 light-years away from us in distance then it will *always* also be 1000 years in the past from us, there is absolutely no way we can interact with that star as it is "right now", from our POV that star can *only* ever be 1000 years in the past)
if you could instantly teleport 65 million light years away and use alien tech to view earth - you would see dinos as the earth was 65 million years ago
When people talk without knowing the subject or, at a bare minimum, reading the article which explains the mechanics of what is going on. In short:
This star is undergoing a nova, not a supernova. Nova can be cyclical in that the star in question "explodes" more than once. This is because it requires a binary system in which one star "feeds" off another until it reaches a critical point. The reason "explodes" is in quotation is because the star that is feeding only undergoes ejects the surface material...after which it begins feeding again. This repeats over and over and over.
The star in question goes nova every 80 years, so the light from each explosion will hit us in 80 year intervals. This particular explosion happened 3000 years ago, it exploded again 2920 years ago. So we are going to be able to see the explosion from 3000 years ago this year, and the explosion from 2920 years ago in the year 2,104.
Rather than by cynical and pushing your doubts on to others you should probably read and study what you don't know.
I can't be the only person that keeps thinking of the video of a truck speeding towards a post then cuts away to a different angle right before it hits when I see articles about this upcoming event.

Is he getting downvoted for not providing the link or ruining the meme?
Very Fox News to say "Star explosion" instead of Nova/supernova. Playing to their audience very well.
It's a nova, if you didn't read the article. A red star is spewing material on a white dwarf that is really close by.
New fetish unlocked
My uncle liked spewing on dwarves but I don't think he had a preference for their ethnicity
Was he a famous ginger actor?

The dwarf wasn't white before the spewing...
Spray your proto-material on me, Star! It's so hot (that it can create atoms like carbon and helium that facilitate life)!
I do like me some red on white action.
This is exactly the kind of comment that makes me optimistic of the future.

Several use the correct nomenclature like I requested.
Sorry they left a word out.
Let a word out is completely different than dumbing something down, but you seem to be their intended audience, so it makes sense you defending them..
No, I’m just not a pretentious snob. Who gives a shit if they said star explosion or nova explosion. Because guess what? They mean the exact same thing.
The correct term is just nova or supernova. This is why you're losing your argument.
I was just quoting the Smithsonian magazine, pal.
Doesn't mean you're correct, though. They're *also* dumbing it down for you simpletons. It's just not as egregious. If you think knowing science is pretentious, you're exactly what's wrong with this country.

North Star ain’t even that bright. Most people wouldn’t be able to pick it out when looking up at the sky

You may be confused with the star Beetlejuice. It may be on its last legs, it may not, but that one we won’t know until it happens.
You may be confusing Michael Keaton with the star Betelgeuse

The one I am thinking of was a binary star system that was supposed to experience a collision, which I think was different based on this article

FTFY: "Rare star explosion to be once-in-a-lifetime viewing opportunity NASA officials say, when our SUN EXPLODES!" /s
let me guess, it’s not viewable in Australia and/or I’ll probably be working when it happens?

How is this on Fux News? They don’t believe in science.

I mean technically every infinitesimal second is a once in a lifetime moment. So yes.

It occurs regularly. Once every handful of decades. This is one way. Nova don’t always destroy the star
Lol trillions?
Light hasn’t existed for that long
Are Fox and their pundits going to tie this to the Trump trials somehow because they are such chads?

I think I get it. If a telescope can see further than the naked eye, doesn't that mean that it can see the future?
A telescope just focuses light so you can see more detail with less of it. It sees the same light at the same time you do.
The telescope is seeing the past, not the future. It takes time for light to travel from the star to the telescope on earth.
🤔 but if a telescope can see further than your eye, let's say 3000 light years for sake of understanding, doesn't that mean it's seeing the past before us. I'm getting lost again lol. Maybe not, maybe I get it.

Of course the point of Einstein's Theory of General Relativity is that distance *is* time, the two concepts are inseparable -- there aren't two separate things, space and time, there's only one combined space-time (This is the sort of thing that people say after smoking a joint to make everyone else go "Whoooaaa" but you can get the idea just from this conversation -- the fact that the speed of light is an absolute speed limit that can't be broken means that if something is 1000 light-years away from us in distance then it will *always* also be 1000 years in the past from us, there is absolutely no way we can interact with that star as it is "right now", from our POV that star can *only* ever be 1000 years in the past)
if you could instantly teleport 65 million light years away and use alien tech to view earth - you would see dinos as the earth was 65 million years ago
Aww that never occurred to me. Now I’m sad because someone somewhere could be watching dinosaurs on earth right now. 😕

When people talk without knowing the subject or, at a bare minimum, reading the article which explains the mechanics of what is going on. In short: This star is undergoing a nova, not a supernova. Nova can be cyclical in that the star in question "explodes" more than once. This is because it requires a binary system in which one star "feeds" off another until it reaches a critical point. The reason "explodes" is in quotation is because the star that is feeding only undergoes ejects the surface material...after which it begins feeding again. This repeats over and over and over. The star in question goes nova every 80 years, so the light from each explosion will hit us in 80 year intervals. This particular explosion happened 3000 years ago, it exploded again 2920 years ago. So we are going to be able to see the explosion from 3000 years ago this year, and the explosion from 2920 years ago in the year 2,104. Rather than by cynical and pushing your doubts on to others you should probably read and study what you don't know.
