SUMMARY: A global team of radio astronomers think they might have found the youngest black hole or neutron star approximately 30 million light-years from Earth. A supernova in exactly the same location was found to have exploded some time around 1983, and subsequent observations have found a brightly-emitting object at the very centre of the supernova remnant. They still can't tell if it's actually a black hole, or just a neutron star or pulsar, so further measurements will be required.

What do you think about this story? Post your comments below.

:huh: If you look at the image closely, you might notice that actually a neutron star... if it's a black hole then all the gas surround this object should be sprial inward...

If you look at this image closely, you'll see it is artwork, not photographic.

I wonder when they'll be able to make similar observations on SN1987A in the LMC.

hi
When a large star runs out of fuel it can no longer support its heavy weight. The pressure from the star's massive layers of hydrogen press down forcing the star to get smaller and smaller and smaller. Eventually the star will get even smaller than an atom. well that's how a black hole forms...however there's a star in the middle of that 'black hole' so i think it's not likely to b a black hole... h34r:

1.ENERGY NEED TO BE RETREVED- HOW according to present theories ?
2. Universe has such processes in abundance and New models or Science has to

integrate Energies from Fields and Flows as well.


3. Where lies the Electromagnetic Fields interlinks to such Phenomena ?

Obviously Cosmic Pot Energy Theory helps to integrate SOURCE,FIELDS,FLOWS and REflectors observed in the Unverse.

If this is 30 million light years away, how is it that we think a neutron star might have exploded there in 1983? Is this just another example of poor English, or do neutron explosions move outward a million times faster than light?

"A supernova in exactly the same location was found to have exploded some time around 1983..."

It is the custom to talk about observed cosmic events in terms of when the light from the event got to us. Usually the context removes any ambiguity. If you can think of a better way to express this, that does not lead to ambiguities, please suggest one.

To say that the event happened 30,000,021 years ago would be very wrong since we don't have that many significant digits in the distance. Certainly, if we observe the neutron star or black hole accretion disk now, we will see what it looked like when it was 21 years old.

Looking at the big picture of Space with all it's theories and changing facts, this lay observer often gets confused. When I read about something happening today possibly related to something happening three years ago, that to me is the time period my brain calculates. But that isn't true is it? If I really stop to think about it, something that is 30 billion light years away can't be happening right now or even three years ago; it happened 30 billion years ago and we are just now seeing it because the light has become visible. Am I correct or not? If I'm correct then why do the articles I read make it sound like it is happening now instead of long long ago. Why can't it be said we are seeing something that happened __billion, ___million years ago. And isn't it fantastic!

You are correct, and some science writers are more careful to say something like "We are now seeing it as it looked twenty-one years after the explosion which happened about thirty million light-years away thirty million years ago."

For a lot of scientists, the 30 million year time delay is understood, and they are jaded to the fantastic aspect of the great distance, so it is less cumbersome to talk about it as the time since the event was observable on Earth.
