Note: Nothing to do with our own solar system, but it is interesting nonetheless.

It looks like scientists may have spotted the first planet outside of our solar system that is potentially habitable for life.

(Space.com) An Earth-like planet spotted outside our solar system is the first found that could support liquid water and harbor life, scientists announced today.

Liquid water is a key ingredient for life as we know it. The new found planet is located at the “Goldilocks” distance—not too close and not too far from its star to keep water on its surface from freezing or vaporizing away. [...]

The new planet is about 50 percent bigger than Earth and about five times more massive. The new “super-Earth” is called Gliese 581 C, after its star, Gliese 581, a diminutive red dwarf star located 20.5 light-years away that is about one-third as massive as the Sun.

This is the first terrestrial world discovered outside of our solar system that orbits within the habitable zone of a star. Although the planet orbits a short distance around its star (about 13 Earth days), life forms could easily survive on this world due to the dimness (or rather lack of heat) from the red dwarf sun.

Scientists are probably going to take a second look at this, and it will be interesting to see whether or not we will be able to locate features upon this world in the future.

Note: I’ve just alerted Paul over at Centauri Dreams, who should have an interesting analysis regarding this discovery.

Update (4/25): Paul has posted his analysis here with a video over here. Exciting stuff!

Many space geeks (I included) seem to be excited about an image by KOKOGIAK displaying the 88 largest bodies in our solar system (of which 83 are “terrestrial” or have a surface we can actually land upon).

After searching online on these various worlds, many with an abundance of ice water upon them (a good sign), it became apparent that many of these worlds would not become favorable homes (for raising kids) due to either radiation, distance or lack of appeal.

Currently there seem to be four worlds that show some promise of becoming future homes which are:

• Mars (which has tolerable levels of radiation)
• Ganymede (which has a magnetic field)
• Callisto (which is not within Jupiter’s radiation belts)
• Titan (atmosphere plus Saturn’s magnetic field may protect it)

Unless artificial magnetic fields can be created upon other worlds, they may only attract corporate industries and scientists, but not the huge populations necessary in order to establish our species as a “space faring civilization.”

Hopefully I’ll get some more time to post about these four worlds, as they hold much promise for our race four or five generations from now.

With various companies coming up with various ways of accessing the final frontier (whether through space elevators, rockets or Maglev launches) it is good to see an insurance company willing to help reduce the risk of travel, at least financially.

(Scotsman.com) Bupa Travel has decided to get on the act – it is to add space travel to its insurance policy line-up.

“We are looking into space tourism as a real market for the next generation of travellers,” said Nick Potter, Bupa Travel’s general manager.

When you begin to see more insurance companies adding space travel to their policies, it is a definite sign that “space culture” is quickly becoming mainstream.

Note: I have not been as faithful as I desired to in posting here (as life has been fairly busy) but these are some of the stories that may catch your eye regarding our future among the stars.

Astroprof discusses the dangers of bone loss due to the lack of gravity in space.

Despite NASA’s attempts at reducing the loss, the percentage rate exceeds that of a woman with osteoporosis, leading I. Tenor (a commenter) to conclude that exile from Earth may be the price we pay for colonizing the stars.

Jack Kennedy from Spaceports discusses Matsen Space System’s attempts at winning the Lunar Landing Analog Challenge later on this year.

There main competitors are Armadillo Aerospace and Blue Origin, who may put up some fierce competition.

The Space Review has an article about finding life in the solar system. My views of this are fairly dim (as finding microbes does not help us reach the stars).

However, since scientists are looking for life near water ice, this research should prove quite useful in helping us locate future settlements as water is the main ingredient for life (at least carbon based life forms).

Centauri Dreams has an excellent article discussing how the sun’s rays spin asteroids. Although this alone may not amaze anyone who is not a hard core space geek, this revelation does help put some weight behind the solar sail.

Ted Semon from the Space Elevator Blog informs everyone that Germany is forming their very own space elevator competition scheduled for February of 2008.

This competition is not as ambitious as the Spaceward’s Space Elevator competition, however the fact that they are organizing it may help inspire other nations to follow suit.

Hopefully I will have some time tonight to discuss some other issues on the back burner, including NASA’s paradox, Jupiter’s Ganymede, and the missing ingredient to call the Moon, Mars and Europa home.

Stay tuned.

Update: Corrected spelling of Ted’s last name (Semon it is! Curse the spell checkers!) Also, I should have some free time later on today (at last).

Despite the fact that my default team lost (since the Colts took out the Patriots) one of my favorite parts of the super bowl was this commercial.

Despite the humor of it all, wouldn’t it be great if outer space was this boring?

Note: This by far was perhaps the funnest super bowl commercial that aired.

With the holidays around the corner (or just ending if you are Jewish) there seems to be a reflection of when Jesus Christ was born in Bethlehem.

Despite tradition placing his birth in late December, some astronomers think Christ may have been born in the summer time–based on the star hailing his entrance into the world.

(MSNBC) The show started on the morning of June 12 in 3 B.C., when Venus could be sighted very close to Saturn in the eastern sky. Then there was a spectacular pairing of Venus and Jupiter on Aug. 12 in the constellation Leo, which ancient astrologers associated with the destiny of the Jews.

The crowning touch came on June 17, when Jupiter seemed to approach so close to Venus that, without binoculars, they would have looked like a single star.

Their is a brief mention of a star in the scriptures, which many see as a prophetic hint towards the coming Messiah.

Although his birth and life are often the cause of debate on our planet (as one can notice by glimpsing over at Cosmic Log’s comment section) no one can deny that this man has probably influenced the world more than any other person (as our economy can at least tell you that).

Whether you are a theist, atheist, IDist or agnostic, I wish you all a Merry Christmas (or Happy Hanukkah, Festivus, etc.).

Note: It’s not a space elevator, but it may be the worlds tallest Christmas tree (see this image for a reference).
