Star Gives Birth to Possible Black Hole in Hubble and Spitzer Images

Star Gives Birth to Possible Black Hole in Hubble and Spitzer Images


For the first time ever,
astronomers might have witnessed a star actually become a black
hole right before our eyes… or telescopes. In this visible
light image from the Hubble Space Telescope, we can see a
large star about 25 times the mass of our Sun around 22
million light years away in the galaxy NGC 6946. This was in
2007. But in a Hubble image from 2015, looking with the same
filters at the same wavelengths, the star appears to be gone. One
possible explanation – the star died and became a black hole.
But it gets weirder. The most prevalent theory for how a black
hole forms is through a supernova – if a star is big
enough, at the end of its life it will eject its outer layers
at high velocity in a massive explosion while the inner core
collapses into a very tiny space, creating a gravity well
so great that light can’t escape. Literally, a black hole.
So did we see this star go supernova? No, not really. A
team of astronomers was monitoring this star with the
Large Binocular Telescope in Arizona and saw the star get
brighter in 2009, but not nearly as bright as a supernova. They
call it a failed supernova. The star does expel its outer-most
layer, but relatively gently and not in a big explosion. Ok, so
this star got brighter in visible light in 2009, and then
disappeared in visible light. How do we know it’s not just
hidden behind a cloud of dust or something? The team checked for
that; they looked at infrared observations from the Spitzer
Space Telescope, which would be able to see the heat of dust
warmed by the star. What we see with Spitzer is there is some
emission in the mid-infrared, but it’s fading and fainter than
what you’d expect to see with a hidden star. The team thinks
instead that this infrared light is from the heat of gas falling
back onto the newly formed black hole. To help confirm that this
star is now a black hole, the team plans to analyze
observations taken with the Chandra X-Ray Observatory, which
would be able to reveal X-rays being emitted by the gas falling
into the black hole. The team also wants to continue
monitoring the star’s location in visible light with Hubble,
in case the star is still
there and re-appears, and they’ll want to look at the
location with the upcoming James Webb Space Telescope to check if
there’s a surviving star hidden by cooler dust than can be
observed with Spitzer. So if this really is a black hole
birth, what does that mean for astronomy? First of all, this
would show that a star doesn’t need to go supernova to form a
black hole. Astronomers actually haven’t seen as many supernovas
occur with the largest stars as they would expect to see, and
they’ve been wondering why this is. Perhaps 10 to 30 percent of
massive stars don’t go supernova and are still able to simply
form a black hole. If future observations confirm this team’s
findings, this would be the first birth of a black hole ever
witnessed and the first failed supernova ever discovered, both
of which would usher in an exciting era of astronomy
research. www.nasa.gov/hubble

  1. Wow what's new, the video starts with CGI to make me believe anything else you guys show (even though it's a picture with random dots of lights). Not surprised I see way more CGI all throughout too.

  2. Very interesting, now please tell us what you know about the aliens please? 😂 👽 we know there's something going on, just need confirmation 😆👽🚀

  3. I love Astronomy and Astrophysics. And the teacher. Ja = D … it's a joke, but you're really beautiful. Greetings from Argentina.

  4. You know what else is interesting, no scientist has ever witnessed a star being born, just stars dying out which is proof that the universe was created by something not just a coincidence.

  5. PSEUDOSCIENCE for nitwits

    the generative ''force'' in the universe is electricity.
    dr judy wood presented the EVIDENCE even a youtube simpleton can understand

  6. [01:09] "not nearly as bright as a supernova"—is that an understatement by 100,000×… If it was bypassing the supernova stage, that'd be the hump at 2004-2005.5 while endothermic iron-fusion was proceeding but stalling against too much exothermic silicon-fusion… So what's the 2009 spike—'the opening of the mouth ceremony' of a 'supermummy'…

  7. Lensed or Time is different in that spot.

    Movement of ejected objects should trace from it like a Firework Star burst.

  8. Wouldn't an obscuring dust cloud also slow down the radio emissions tho? The radio emissions are now refracting through a medium, so they get slower until they emerge from the other side of that medium. Maybe we'll see evidence for the obscuring dust cloud at a later date when the refracted & slowed emissions finally reach us.

  9. If the core went from fusion directly to black hole, would there even be an explosion? It doesn't seem like there would be anything for the in-falling matter to bounce off of, just an endless drop to singularity or a wild ride into an accretion disc or jet. I'll guess we're seeing it more or less edge on, and over the next decade or so we'll start to observe the jets.

  10. Video presenter was pristine. Incredible pronouciation and tone, especially for such a young voice. Very well done.

  11. This event appears to be more of an electrical event similar to a power surge compared to violent understanding of black hole formation. The stellar body may very well re-appear if that is the case.

  12. I love science but I find the constant use of background noise, in this case music that might otherwise be pleasant to listen to, quite annoying when trying to listen to the speaker. Why do we humans have the need to use such distracting background white noise, which adds nothing to a presentation?

  13. Could what you saw in 2007 actually be a supernova? Seeing as you were looking at the star in another galaxy, a change in brightness would be unnoticeable to a satellite in orbit around Earth. Or maybe the star had been blocked out by the gas emitted from the supernova? I'm probably sounding dumb right now, but would it be possible?

  14. What about light from what's behind the star? If it turned into a black hole, wouldn't scientists be able to get data on light from behind it that is being bent?

  15. Starkiller Base confirmed! (It happened a long time ago, in a galaxy far far away… and we are looking into the past…)

  16. If the observed does not match the Black Hole theory. Stop saying that a black hole has been formed.

  17. Awesome video, but ugh… that music. The silence of space would've been better than that .. thing.

  18. I really want to believe in Black Holes. I dont see anything suggesting Black Hole from the side by side pics. The idea that a Star vanished is rather interesting but thinking more that's now blocked from view rather than abducted by Aliens and held hostage or transformed into an impossible existence.

  19. What happened to that Star?
    Ask our Moon…
    If our Heliosphere shrunk far enough Jupiter or Uranus is prime candidate to become a Star. The only thing possibly keeping it from being next in line of being the Sun of our Solar System after our Sun dies is it's own axis. Everything is in a bubble. If you are not in the bubble. You become the bubble. The Universe is regenerating and procreating. It is not devouring itself. The whole Universe of Galaxies are multiplying.

    I could explain why I believe such crazy things but it's a very long story of connecting dots backed by scientific info & observations…

    Black Holes are not Real

  20. yes it does sound logical that a massive star might simply collapse on itself rather then go super nova first. – but since a black hole is formed , we might for 1 observe it sucking on its gasses, if that does not happen , something else has occured, if it is still a black hole , we might look for nearby stars, if one of the nearby stars gets sucked into something we cant see, then we directly have observed a black hole, if one day if it moves to one of the near stellar objects.
    then we swould know for sure, right now it could be that something blocks the star light, or something else has happenend that we have not yet onbserved nor contemplated. might even be due to artifcial reasons ( aliens ) though that is the more far fetched i guess, but not that far fetched :p

  21. Q: How special are black holes with the property of con-suming other objects in the universe?
    And: If an object in the universe can change into a black hole, why should that object be a star?

  22. actually, those stuff we see today are so far, it will take a century for a single light to travel through space to our eyes (scope), which means some stuff we see are all just remnants from the past.

  23. My theory: godlike alien beings using star killing weapons in a devastating galactic conflict.
    Or maybe… black hole formation is just more complicated than we though

  24. Ok quick question – if the universe is approx 13,8 billion years old, and nothing can travel faster than the speed of light, how is the observable universe estimated to be 93 billion light-years in diameter?? And that’s only the observable universe… explain that mystery NASA…

  25. Me and my 2 daughters shaw 7 stars born at a time and 7 following and each star has the exact same space in between. And a bigger distance after the 7nth one. At 19:00 in Malaga Spain.
