Déjà vu
With the newly doubled energy capacity of the ship the captain has asked SAI to take the ship o the farthest safe star they can travel to, a necessary specification after the trouble with the neutron star. The next destination is the distant star Deneb.
Episode 7 Synopsis:
With the ship at it's new double energy maximum the captain has asked SAI to take the ship as far as safely possible. SAI has chosen the distant star Deneb, and after a much longer than usual flight the ship reaches it's destination. The star appears very similar to Rigel and the crew wonder why they are back there. SAI explains that they have actually traveled almost 2000 light years and they are now orbiting the blue supergiant Deneb, and that again the energy reserves are quickly on their way to maximum capacity again. The captain tells her to find all blue stars and note their locations, and to inform him when they need to recharge the ship. Noko enters the bridge saying that in order to complete his upgrades on the ship, he needs a material called Zirconium in order to reinforce the reactor, much more of it than the replicators are able to supply. SAI suggests that there is a recently discovered Zirconium star within safe traveling distance, Noko says that if the ship can get close enough he has a way of retrieving the substance, and assures the captain that the upgrade will be well worth the time. The captain agrees, the engines start up and they blast off to the Zirconium star.

| Deneb is the birghtest star in the Cygnus contellation, hence it's designation Alpha Cig. |
Deneb is a blue - white supergiant even larger than Rigel. The star has 20 times the mass of the sun and is an enormous 108x larger! One of the largest known blue supergiants. The surface temperature is thought to be approx 8,400K and it's located 1,550 lightyears away from the sun with 60,000x it's luminosity. Deneb is so large that if it were our sun the orbit of earth would be inside it.
Deneb is actually brighter and larger than Rigel, though it is more than twice the distance away so appears considerably dimmer on Earth. Due to it's size the star is burning though it's fuel at a extremely accelerated rate and is expected to die in a supernova in only a few million years. It is thought the Deneb is still expanding ad will eventually become a red supergiant.
The name Deneb is derived from the Arabic "Dhanab ad-Dajāja" meaning "tail of the hen".
Believe it or not, the 'zirconium star' is actually something that has been quite recently discovered (2008... But I only just read about it) and found it s interesting that I had to involve it somehow! If you simply can't wait to read about it check it out here: http://www.ras.org.uk/news-and-press/157-news2010/1898-a-sparkling-zirconium-star... Amazing stuff!
