Tycho's Supernova Remnant

Explanation: What star created this huge puffball? Pictured above is the best multi-wavelength image yet of Tycho's supernova remnant, the result of a stellar explosion first recorded over 400 years ago by the famous astronomer Tycho Brahe. The above image is a composite of an X-ray image taken by the orbiting Chandra X-ray Observatory, an infrared image taken by the orbiting Spitzer Space Telescope, and an optical image taken by the 3.5-meter Calar Alto telescope located in southern Spain. The expanding gas cloud is extremely hot, while slightly different expansion speeds have given the cloud a puffy appearance. Although the star that created SN 1572, is likely completely gone, a star dubbed Tycho G, too dim to be easily discerned here, is being studied as the possible companion. Finding progenitor remnants of Tycho's supernova is particularly important because the supernova was recently determined to be of Type Ia. The peak brightness of Type Ia supernovas is thought to be well understood, making them quite valuable in calibrating how our universe dims distant objects.

[al baby]

Awesome its filled with stars

[sig226]

[MaxMax]

Stars were meant to be seen and not heard

[DuncanWaring]

Is it filled with stars, or are those just a bunch of stars behind it shining through?

[mikrofon]

Sure’n ‘tis a shamrock I see in thar’...

[Bloody Sam Roberts]

It is the remnants of one star after it went nova. The stars you see ar shing through the translucency of the remnants.

'al baby' was quoting from "2001: A Space Odyssey" and "2010"....David Bowman's last words, as he entered the monolith were, "My God. It's full of stars".

[DuncanWaring]

Aha! Inside joke.

Last time I saw 2001, Richard Nixon was President.

[Spirochete]

Is it filled with stars, or are those just a bunch of stars behind it shining through?

A lot of them are in 'front' of it, between us and the nebula. Both we and it are embedded in a swarm of stars.

[tx_eggman]

Best ... Lego ... Ever

[DuncanWaring]

Hmmmm ... “in front”.

Yet another possibility that hadn’t crossed my mind.

Been happening a lot lately.

[fieldmarshaldj]

“Mama mia ! That’s uh spicy-ah meat-ah-ball !”

[Ciexyz]

It's wearing the green for St. Paddy's Day!

[Bullish]

Wow.... Trip!

[potlatch]

Watch out!!

 

[potlatch]

Lost in space..

[devolve]

[devolve]

.

LOL!

Wild stuff!

[potlatch]

Very pretty.

[potlatch]

Yeah, I have plans for that gif!

[tet68]

I take it that is the president bowling?

[devolve]

.

Thanks potlatch

I can just imagine what your plans are!

[potlatch]

Imagination is funny, lol.

Too many ideas, too many irons in the fire, can’t get to half of them!

[devolve]

.

Better than no ideas!

[potlatch]

I think you can get more ‘ideas’ with animated gifs rather than still images. They ‘do’ something.

But a good idea one day may fade out and not interest me a couple days later. Takes time and topics can change fast.

[devolve]

.

Yup

That one is a <table BG

I-M wuz not exiting after compositing

[potlatch]

Your TP ones with the ‘Starz’ are always pretty. That BG may have been your major ‘find’!!

Remember I couldn’t composite in IM a week or so ago, tried and tried.

[devolve]

.

I have been able to composite at the I-M Studio site

But no go at 3 sites today

[potlatch]

Some days it does and some it doesn’t it seems. This is Friday night, probably more using it right now.

[devolve]

.

Right

Lots of pro use it too - for light and shadow FX on photograph areas

[potlatch]

[Lots of pro use it too]

You think? I would think they have good Photoshop programs that do hundreds of things and you can get extra plug-ins too for special effects.
