Hubblecast 32: Born in Beauty – Proplyds in the Orion Nebula.
Visible to the naked eye, only 1500 light-years from Earth, the great Orion Nebula has been known and revered since ancient times.
A popular target of Hubble, researchers have now identified 42 new discs within it that could be the beginnings of new planetary systems like our own.

14-Dec-2009: A collection of 30 never-before-released images of embryonic planetary systems in the Orion Nebula are the highlight of the longest single Hubble Space Telescope project ever dedicated to the topic of star and planet formation.
Also known as proplyds, or protoplanetary discs, these modest blobs surrounding baby stars are shedding light on the mechanism behind planet formation. Only the NASA/ESA Hubble Space Telescope, with its high resolution and sensitivity, can take such detailed pictures of circumstellar discs at optical wavelengths.
Looking like a graceful watercolour painting, the Orion Nebula is one of the most photogenic objects in space and one of the Hubble Space Telescope’s favourite targets. As newborn stars emerge from the nebula’s mixture of gas and dust, protoplanetary discs, also known as proplyds, form around them: the centre of the spinning disc heats up and becomes a new star, but remnants around the outskirts of the disc attract other bits of dust and clump together.
Proplyds are thought to be young planetary systems in the making. In an ambitious survey of the familiar nebula using Hubble’s Advanced Camera for Surveys (ACS), researchers have discovered 42 protoplanetary discs.
Visible to the naked eye, the Orion Nebula has been known since ancient times, but was first described in the early 17th century by the French astronomer Nicolas-Claude Fabri de Peiresc — who is given credit for discovering it. At 1500 light-years away, the nebula, also known as Messier 42, is the closest star-forming region to Earth with stars massive enough to heat up the surrounding gas, setting it ablaze with colour, and making the region stand out to stargazers.

Hubblecast features news and Images from the Hubble Space Telescope (HST).
The space-based observatory is a collaboration between NASA and ESA. The observations are carried out in visible, infrared and ultraviolet light. In many ways Hubble has revolutionised modern astronomy.
The Hubble Space Telescope has made some of the most dramatic discoveries in the history of astronomy. From its vantage point 600 km above the Earth, Hubble can detect light with “eyes” five times sharper than the best ground-based telescopes and looks deep into space where some of the most profound mysteries are still buried in the mists of time.

Lyrics:
“Intergalactic”
Intergalactic Planetary Planetary Intergalactic
Another Dimension, Another Dimension
Well Now don’t you tell me to smile
You stick around I’ll make it worth your while
Got numbers beyond what you can dial
Maybe it’s because I’m so versatile
Style profile I said
It always brings me back when I hear Ooh Child
From the Hudson River out to the Nile
I run the marathon til the very last mile
If you battle me I will revile
People always say my style is wild
You’ve got gall you’ve got guile
To step to me I’m a rapophile
If you want to battle your in denial
Coming from Uranus to check my style
Go ahead put my rhymes on trial
Cast you off into exile
Intergalactic planetary
Planetary intergalactic
Jazz and Awol that’s our team
Step inside the party disrupt the whole scene
When it comes to beats well I’m a fiend
I like my sugar with coffee and cream
Well I got to keep it going keep it going full steam
Too sweet to be sour too nice to be mean
On the tough guy style I’m not too keen
To try to change the world I will plot and scheme
Mario C likes to keep it clean
Gonna shine like a sun beam
Keep on rapping cause that’s my dream
Got an A from Moe Dee for sticking to themes
When it comes to envy y’all is green
Jealous of the rhyme and the rhyme routine
Another dimension new galaxy
Intergalactic planetary
Intergalactic planetary
Planetary intergalactic
From the family tree of old school hip hop
Kick off your shoes and relax your socks
The rhymes will spread just like a pox
Cause the music is live like an electric shock
I am known to do the Wop
Also known for the Flintstone Flop
Tammy D getting biz on the crop
Beastie Boys known to let the beat… drop
When I wrote graffiti my name was Slop
If my rap’s soup my beats is stock
Step from the tables as I start to chop
I’m a lumber jack DJ Adrock
If you try to knock me you’ll get mocked
I’ll stir fry you in my wok
Your knees’ll start shaking and your fingers pop
Like a pinch on the neck of Mr. Spock
Intergalactic planetary
Planetary intergalactic
Another dimension do it
Full credit of this video goes to the beastie boys =)

The final image is η (Eta) Carinae, a pair of massive and extremely volatile variable stars at a distance of 7,500 ly. The larger of the two, η Car A, is thought to be close to the end of its life. The image was taken with WFPC2 before it was replaced by WFPC3.
