Light echoes ripple from ancient supernova

[blackskvll]

thats because we haven't figured out how to 'fold' the fabrics of the universe

i hate this universe,human cant travel on 3000,000km/sec,there's no way that we could go in to another galaxy,and a lightyear is "how light travel in a year",and if we could not reach the speed of light,its totaly imposible,because if we travel way slower than the light-speed,it take us hundreds or thounands of year to reach a light-year

[ken15151515]

as it said,400 years had passed and the light reach the earth after the explosion,it got to be way too far,since the light travels at aprox. 300,000km/sec,,,bassed in my calculations,the supernova is about 3,658,136,000,000,000km away from us

is it light as in faint or light as in bright?

[ClanRooster]

Observing distant stellar phenomena is all about collecting enough photons to reveal the object in detail. For example, if you look at the milky way for just a few seconds it will look 'faint'. However - if you look at it for five minutes you eye will have received more photons and it will look 'brighter'. The best example of this are the famous Hubble Deep Field (HDF) images. After about ten days focussed on the same piece of sky the Hubble collected enough photons to resolve a myriad galaxies.

More thoughts on this very interesting video. Firstly the phenomena deserves more careful study. Assuming we are looking at the westward progression of the lightwave we should also observe the wave at the other three quadrants - north, south and east. Surely there is an opportunity to observe previously 'unlit' parts of space here, and if dark matter is of the 'macho' type it would be illuminated as a matter of course.

...ok...

you can see similar things, without the moving, on google earth if you switch to the night sky version.

My attempt at an explanation of this video: The 'light echo' is in the 'LMC' - Large Magellanic Cloud - a faint object visible only in the southern hemisphere in the Dorado constellation. SNR0509 means 'Super Nova Remnant' 0509. The original supernova event occurred around 1600 (AD). The LMC is about 150,000 light-years from earth, and is names for Ferdinand Magellan. Chandra is an orbiting X-Ray Observatory. The end bit is a timelapse animation rendered from several years optical observations.

Very well put, but you talk so robotic like you want a screwdriver up your ass as a congratulations.

You're smart! Now be sensible. Be sociable. Be less you.

This is a scientific video, if you can not understand what he said, don't fuss about it, go watch cartoons. That's were you belong.

[ClanRooster]

Lol ! My first hater ! Did your keen observation of my message extend to counting the characters in my message I wonder? Exactly 500 characters - go on - count-em... Regarding writing style -I see you have taken the form of a backhanded complement to the next level.

We call that brain envy. :(

[ohwhatsthis]

Yeah that was totally unnecessary dude. He explained it, he doesn't need to dress it up for you to get it more.

[thoughtwaretv]

Thank you ClanRooster.

[maaanddeuta]

cdn't understand what's shown.Surprised to hear about 'echoeing' of light.

[butxuza]

wow, is the speed of this glow in real time scale?

I mean if I look at it I will see in this speed?

[IFuREADthisURstupid]

yes you idiot its traveling at the speed of light over billions possibly trillions of miles...look at car from 1 mile away and you cant tell how fast their going

[Esafix]

Awesome!
