In the Science@ESA series Rebecca Barnes will take you on a journey of discovery into the rapidly evolving field of space astronomy and planetary exploration.

In this second episode Rebecca takes a close look at Planck – a European Space Agency mission built to detect radiation from the microwave portion of the electromagnetic spectrum. This mission will help find answers to some of the most important questions in modern science.

The Big Bang is the cosmological model of the initial conditions and subsequent development of the Universe that is supported by the most comprehensive and accurate explanations from current scientific evidence and observation.

As used by cosmologists, the term Big Bang generally refers to the idea that the Universe has expanded from a primordial hot and dense initial condition at some finite time in the past (currently estimated to have been approximately 13.7 billion years ago), and continues to expand to this day.

Planck was selected as the third Medium-Sized Mission (M3) of ESA’s Horizon 2000 Scientific Programme, and is today part of its Cosmic Vision Programme. It is designed to image the anisotropies of the Cosmic Background Radiation Field over the whole sky, with unprecedented sensitivity and angular resolution.

Planck will provide a major source of information relevant to several cosmological and astrophysical issues, such as testing theories of the early universe and the origin of cosmic structure.

Planck was launched on 14 May 2009 together with the Herschel satellite. After launch, Planck and Herschel separated and are now proceeding to different orbits around the second Lagrangian point of the Earth-Sun System.

(Pluto is no longer classified as a planet, but it’s there for size comparison. As for the Sun, it was never a planet but is here for the very same reason.)

I always wanted to see a one-by-one comparison of the sizes of the planets, so I put the numbers into my 3d program. These are all correct proportions (of size, not distance).

Tamen, the final planet, was a world we created when we were children. Obsessed with size, we said it was 1,000 times larger than Earth’s sun (this was actually only 100 times larger, because 1000 made the sun so small you couldn’t really see it). We later learned that such a planet would have to much gravity that not only would no living thing survive, but you may get a nice little black hole started right there in the planet!

Wow… and I just realized that had the sun have been sitting where it is in this video, it’d be sucked into the planet instantly.

The Earth is formed by accretion of spatial particulates and large masses and eventually formes an outer crust. Video follows with speculation of early plates and land masses and their movement through time. **Clip taken from National Geographics**

The search for Earth-like planets is reaching a fever-pitch. Does the evidence so far help shed light on the ancient question: Is the galaxy filled with life, or is Earth just a beautiful, lonely aberration? If things dont work out on this planet Or if our itch to explore becomes unbearable at some point in the future Astronomers have recently found out what kind of galactic real estate might be available to us. Well have to develop advanced transport to land there, 20 light years away. The question right now: is it worth the trip?

Pluto Mercury Mars Venus Earth Neptune Uranus Jupiter Saturn
Name of Stars as shown:
Sun Sirius Vega Pollux Arcturus Aldebaran Rigel Deneb Pistol Star Betelgeuse Antares VV Cephei

=======================================
NOTE: This video is a edited version of “Energy vs Information” made by jaxxrr (to which all credit goes to), I was very impressed by the production value both the video and music.

Seeing that it received few hits, which may be due to the title and tags. In order for more people to see and enjoy this video I mirrored the edited version, so people won’t get too side tracked on the political message. (Although I’m against wars and big oil as well)

Please see the original version if you like here http://www.youtube.com/watch?v=Z1NkoZeTEWc

-=NOTE=-
This video was made BEFORE “VY Canis Majoris” was listed as the largest known star, When this video was made 2006 by it’s author JAXXrr, the star “VV Cephei A” was listed as the largest known star.

For a list of current largest “known” stars see http://en.wikipedia.org/wiki/List_of_largest_known_stars
Keep in mind while watching this video that the “largest known stars” are all found in our own galaxy (The Milky Way). We know of only of a very few of the estimated 200-300 Billion stars that make up our galaxy, which is just ONE of at least 300-500 billion galaxies in the visible Universe.
