Remnants of a Super Nova

[BettaWatchOut]

A supernova is a stellar explosion that creates an extremely luminous object.

A supernova causes a burst of radiation that may briefly outshine its entire host galaxy before fading from view over several weeks or months.

During this short interval, a supernova can radiate as much energy as the Sun would emit over 10 billion years.

The explosion expels much or all of a star's material at a velocity of up to a tenth the speed of light, driving a shock wave into the surrounding interstellar medium.

This shock wave sweeps up an expanding shell of gas and dust called a supernova remnant.

i could take it

Quasars show a very high redshift which is an effect of the expansion of the universe between the quasar and the Earth.

When combined with Hubble's law, the implication of the redshift is that the quasars are very distant.

To be observable at that distance, the energy output of quasars must dwarf that of almost every known astrophysical phenomenon in a galaxy, excepting comparatively short-lived events like supernovae and gamma-ray bursts.

Quasars may readily release energy in levels equal to the output of hundreds of average galaxies combined. The output of light is equivalent to one trillion suns.

Ohhhh Now you're just making stuff up.

There's no science to back any of this.

[Sublime25]

woa impressive, you don't fuck with the nature

[TypeO]

see, now ya went and made us learn something -
cut that shit out - my brain hurts now.

[BettaWatchOut]

but I haven't told you about the center of our galaxy!!!

[TypeO]

actually I love shit like this
makes your brain strain trying to fathom the immensity of it all
like that vid OKC posted a few weeks back showing the relative size of earth, sun and different stars -
mind-boggling

Great Pics! Post moar

hear this...
The galaxy is about 90,000 light-years across.

(Numerical value

A light-year is equal to:

* 9,460,730,472,580.8 km (about 9.461 Pm)
* 5,878,625,373,183.61 statute miles
* about 63,240 astronomical units
* about 0.3066 parsecs)


The Sun is located about two-thirds of the way out from the center in the Orion Arm.

The Sun (and our solar system) is revolving around the center of the Galaxy at a
speed of half a million miles per hour, but it still takes 200 million years for it to
go around once. As far as we can tell, the Sun and the solar system are not moving away
from the center of the galaxy. The Sun has made less than 25 trips around the galaxy in its lifetime.
