hope its not the new movie Skyline is going to be real lol :ship2:

[ballaratdragons]

Probably another thing we can't see.

Some Neutron Star burped out an X-ray burst or something like that :lol:

I won't hold my breathe but I hope it is interesting this time. Thanks H :thumbsup:

[DavidU]

Very tantalising news. I wonder what it is??!!

[mswhin63]

Same working out how to view the program live, anyone know what time WST Aus time is?

[Ric]

I always enjoy the intrigue surrounding these announcements.

Hope it's a good one.

[ballaratdragons]

Any news yet?

[jjjnettie]

It'll be news of a new type of Quasar.
Is anyone taking bets?

[troypiggo]

Despite the clouds, I managed to take a photo of what the announcement is all about.

Soooo cool that.

[ballaratdragons]

Come on NASA!

It's 6:14am US East Coast time. Should be announced by now!
They can have breakfast later :mad2:

:rofl:

[ballaratdragons]

4 hours to go until the 'Live' news coverage!

A cosmic explosion seen 31 years ago may have been the birth cry of the youngest black hole ever observed, which could help researchers understand how black holes are born and evolve.

A baby black hole.

Bags not changing the nappies, that could be deadly.

[ballaratdragons]

Yep, I was right :rolleyes:

Something we can't see :lol:

[troypiggo]

I'm confused. What was the big announcement originally mentioned? Was it JJJ's space.com link above, or was it those 2 huge structures above and below our Milky Way?

[jjjnettie]

The link I posted was the big announcement Troy.

[ballaratdragons]

What 2 huge structures above and below our Milky Way? :shrug:

You've got my interest :)

[mswhin63]

The main reason for its level announcement is 3 things;
The youngest,
closest discovered to our galaxy
and most important borderline Black Hole forming / Neutron star forming.

Anyone want to add

[ballaratdragons]

Thanks Troy.

I hadn't heard about this phenomenon. :thumbsup:

Actually, the big mystery here arises from the observation that the decline in the Supernova optical and radio luminosity, has not been accompanied by a decline in the X-Ray band emissions. The X-Ray emissions have been steady over a period of 12 years (since 1995) which was not expected from a Supernova of this size.

The current Supernova-turning-into-a-magnetar model predicts a decline in X-Rays over a similar period.

They've matched up the observed decline of X-Rays with a model which uses accreting material surrounding a black hole.

They still aren't entirely convinced as they're recommending deeper Chandra or XMM-Newton observations. They'll be looking for short term variations in the X-ray light curve, which could be seen as evidence for ongoing accretion (& hence more weight to the 'Black Hole' theory).

I'm not so sure this announcement was as exciting as we were hoping for.

A definitive "We've finally seen a Black Hole" would've been a much cooler announcement .. oh well … that's astronomy, huh ?

Cheers

These 'structures' are a sort of by-product of their quest to produce a Gamma Ray map of the observable universe.

Behind all this is the search for yet another postulated mysterious substance called "self interacting dark matter" which was, itself, invented to explain a signal picked up by the DAMA dark matter experiment facility in Italy ('96 to 2002).
