A distant star HR 8799 showing four bodies in orbit

This star that has being discovered in 2010 by the W.M Keck Observatory and say that this star has remarkable signatures as described by Nature, in 2010.
I don't think to see this video before or in any MSN, maybe I'm wrong but anyway two Astronomers made a five-year observation video. As this didn't catch the News as far as I know, I made compilation video from only a small short video. It's fantastic to see a direct video of distant alien star 129 light years away.

Exoplanets cast doubt on astronomical theories Astronomers who study how planets form are scratching their heads after two studies have shown that all is not as theory would predict in the world of other-worldly worlds. How planets are born Christian Marois has posted the first challenge, an astronomer from the Herzberg Institute of Astrophysics in Victoria, Canada, and his colleagues, who used the Keck II telescope on Mauna Kea in Hawaii to spot a fourth planet in the star system HR 8799, some 39 parsecs (129 light years) away from Earth1. The planet, HR 8799e, is a gas giant rather like Jupiter, but about ten times as massive — similar to the other three planets in the system, which Marois discovered in 2008. It sits relatively close to its star, at 14.5 astronomical units (AU; one AU is the average distance between Earth and our Sun. Saturn is some 9.5 AU from our Sun, and Uranus is at a distance of some 19.6 AU). The other planets in the HR 8799 system are 24, 38 and 68 AU from their star, respectively."

Nature ( 2010)

After five years they made this striking observation and recorded the Star HR 8799 for this period of 5 years. Resulting in a beautiful first-time video of a distant Alien star 129 light years away from Earth.

Cool but already posted

I just noticed hmmm all the work but hey np good that its known now..

It will be interesting to see what Phage has to say about this! Looking forward to it!

Pretty amazing to see planets orbiting its star in a completely different system, light years away from us. We don't get that kind of view even in our own Solar System.

Here are the artist's impressions of the planets (in order from star):

HR 8799 e


HR 8799 d


HR 8799 c


HR 8799 b


They're all gas giants, larger and more massive than Jupiter.

Those are nice artistic renderings. Love to do that too. The stars and everything in outer space give the inspiration to create and be aware that we are so small and short in time one has to absorb as much as we can absorb and project what we know or how it would look like. Because we can't go there yet, but we want too.
