Space In General

Our galaxy is surrounded by a giant bubble of hot plasma extending hundreds of thousands of light years.
http://www.sciencedaily.com/releases/2012/09/120924123046.htm

This is a recent discovery, and the implications are mind-boggling. Likely the same is true for all galaxies, and all galaxies are entwined and connected by the filaments that make up these truly vast structures. This intergalactic or universal atmosphere operates at a temperature much hotter than the surface of the sun, and possesses electromagnetic properties about which we can only speculate.

Wish I had a telescope. Was walking to the store last night and noticed the immensely bright star above the moon. Didn't know what it was at the time, but looking at the planetarium map through Google Apps, it's Jupiter. 👍

Sorry if this is common knowledge, I didn't know. :P

The usual mind-boggling post.

I'm fed up with being so small, Steve. Fed up!!:grumpy:

The more I look into the intricacies of Space and Time, the more humble I get, yet with this strange delusion of grandeur that I, even so significant, am a part of it. At least for a moment.
We've come a long way in the last century towards understanding our percepts of Time (Both in General, and in special ways) and Space - the two seemingly firmly intertwined.

A new celestial wonder has stolen the title of most distant object ever seen in the universe, at about 13.3 billion light-years away.

In a rare direct photo of a world beyond Earth, astronomers have spotted a planet 13 times more massive than Jupiter, the largest planet in our own solar system.

The planet orbits a star called Kappa Andromedae that is 2.5 times the mass of the sun and is located 170 light-years away from Earth. As a gas giant larger than Jupiter, it's classified as a "super-Jupiter."

Astronomers say the object's immense size places it right on the edge of the classifications for giant planets and a type of failed star known as a brown dwarf. Its official name is Kappa Andromedae b, or Kappa And b for short, and it likely has a reddish glow, researchers said.

"According to conventional models of planetary formation, Kappa And b falls just shy of being able to generate energy by fusion, at which point it would be considered a brown dwarf rather than a planet," Michael McElwain, a member of the discovery team at NASA's Goddard Space Flight Center in Greenbelt, Md., said in a Nov. 19 statement. "But this isn't definitive, and other considerations could nudge the object across the line into brown dwarf territory."

This is a false color, near-infrared (3.8 micron) image of the Kappa And system. The light from the host star (center) has been removed through image processing. The super-Jupiter, Kappa And b (upper left), has a projected separation of 55 Astronomical Units, about 1.8 times that of Neptune's orbital separation. The speckled pattern surrounding the software-generated mask at the center represents residual noise from the starlight subtraction. The Subaru Telescope in Hawaii captured the image in July 2012.

The object is an interesting test case for theories of planet formation, scientists say. Based on observations of this system, the super Jupiter appears to have formed in the same way ordinary, lower-mass exoplanets do, by coalescing from a "protoplanetary disk" of material orbiting a nascent star.

That's because its orbit, somewhat wider than the path Neptune takes around our sun, is at a comparable distance to planetary orbits in the solar system. Additionally, its star, Kappa Andromedae, is relatively young, at about 30 million years old (for comparison, the sun is roughly 5 billion years old). These clues point toward a formation story typical of smaller planets.

Isn't the travel time to mars something like 6 months with current technology? To get 80,000 people there, we would need a very large ship. Obviously not everyone is going at once, but let's say each flight will carry 100 people. You need food, beds, a rec area, etc. for all those people for the 6 month journey. I'm sure by the time we are ready to colonize, the transit time will have been reduced somewhat. But even if it's cut in half, 3 months is a long time for civilians to be in space. I hope this happens in my lifetime, I would love to retire on Mars. :lol:

But then comes the question of who would govern the colony? SpaceX?
 
Anyone see Jupiter last night? Used an app to track it and numerous other stars! Really cool!
 
Yeah when I left work it was right next to the moon as it was rising from the east. Nice yellow tinted color to the moon, and I pass by a Dish Network satellite dish arrangement too. I REALLY wished I had a good camera with me at the time, would have made for an epic photo. :grumpy:

Anyway, NASA is set to make a "big announcement" today. Something having to do with the Messenger spacecraft that orbits Mercury.

Elon Musk wants to shuttle people to Mars for $500k a piece and start a small colony there.

It's much more interesting than 80k too, as Elon confirmed on his twitter stream:

Elon Musk
Millions of people needed for Mars colony, so 80k+ would just be the number moving to Mars per year.

And, yes, I do in fact know that this sounds crazy. That is not lost on me. Nor I do think SpaceX will do this alone.

But if humanity wishes to become a multi-planet species, then we must figure out how to move millions of people to Mars.

Dunno about anyone else, but that sounds awesome.

Sadly, awesome past-my-lifetime, but still bloody cool nevertheless. Even though I'll likely never go into space myself, I'd like to see more people stepping on the moon, and some on Mars in my lifetime. Colonies? Even better.

I had a good look through my telescope at them both last night. Never ceases to amaze me, seeing Jupiter through the 'scope.

Jupiter is the brightest of the points in this photo I took a week or two back:

Should be really interesting, I wonder what it is? Didn't they say they were testing soil from Mars via Curiosity? Have they said another word about that?

I read an article yesterday that basically said it was hyped up more than it should have and that the initial statement from NASA was blown out of proportion and/or misunderstood.
 
Good grief!

- stable polar water ice deposits
- deposited over a long term by comets and asteroids
- redistributing into crater environments which range from 550 to 50 kelvin
- in close proximity to rich organic chemicals
- all the building blocks of life
- images are expected of "unusual phenomena" in the vicinity of these craters

The video conference is still ongoing as I take these notes...

Respectfully,
Steve
