New Evidence Suggests Icebergs in Frigid Oceans on Ancient Mars
Ancient Mars once had surprisingly frigid primeval oceans complete with their own icebergs, new evidence suggests. As you can see here http://www.google.co.uk/images?q=ima...w=1024&bih=555, that frozen Martian sea is a dead ringer for the Antarctic sea apart from the red colour! That says to me that there's no shortage of water on Mars; it's just currently locked up as frozen ocean and permafrost. |

Our Milky Galaxy is not a standard spiral galaxy...
Anyone who looks through a telescope or looks at pictures of galaxies in books will come across pictures of spiral galaxies such as the Whirlpool Galaxy M51 http://en.wikipedia.org/wiki/File:Messier51_sRGB.jpg and the Triangulum Galaxy M33 http://en.wikipedia.org/wiki/File:M33HunterWilson09.jpg.
That is perhaps how we expect galaxies to look like with the spiral starting from the galactic core. However, our very own Milky Way Galaxy isn't a standard spiral galaxy. ![]() It turns out that our home galaxy is, in fact, a barred spiral galaxy and this is what the Milky Way Galaxy really looks like: http://planetquest.jpl.nasa.gov/imag...y_2005-590.jpg. This image was compiled by NASA from all the visual, infra red and radio wave evidence that we to date. There's more about barred spiral galaxies here http://en.wikipedia.org/wiki/Barred_spiral_galaxy. I'm not going to lose any sleep over this and the Milky Way Galaxy does still look kinda cute http://planetquest.jpl.nasa.gov/imag...y_2005-590.jpg in a galactic sort of way.

Hello all
Just wondered if any of you could help me with something i could see in the sky this morning at about 3am. At this point, Jupiter was in the South West as was The Moon. So any ideas what the bright blue and white pulsating looking star in the South East was? It was moving across the sky in a speed relative to The Moon and Jupiter. |

Orion was in that part of the sky at that time. Can you recognise Orion?

Sounds a lot like Sirius (one of the dog stars).
I've just done a bit of reading, and the position i saw last night does seem like the one of Sirius in relation to Orion. I'd always been lead to believe that the North Star was the brightest star in the sky

Keep on seeing a split second pin prick of bright yellow light in the sky. Well I say pin prick it is closer to the size of say Jupiter when it was in the sky a few weeks ago. Maybe I'm seeing things, but it seems to happen maybe a few times a night when I'm outside having a cigarette.

Runway opens at world's first commercial spaceport...
...in New Mexico, USA and there's more here http://www.bbc.co.uk/news/world-us-canada-11611630.
This new spaceport serves as a two-mile (three-kilometre) runway for the Virgin Galactic company which will offer tourist trips into space albeit for a relatively short while. The passengers will get to see the black skies of space and the curvature of the Earth before gliding back to the ground. |

hope they get to see some glittering stars out there... which is more than we got in those (fake ? ) moon pictures... just a black sky !
(I read that Kate Perry has booked a flight for her paramour.... Russell ... a snip at £200,000 ! ) On the unlit, night side of the Moon then it would be very easy to see the stars (much better than Earth!) but the astronauts had, for safety reasons, to land on the Moon and explore during the two week lunar daytime. |

No, those pictures were real all right. Just as with Earth, when the Sun is above the horizon, it can make it a tad more difficult for both humans and cameras to see the much fainter stars even if there's no atmosphere present.

I love it when people who don't even have a rudimentary grasp of photographic exposure, then claim to be able to say that the Moon landings were faked

Before you embarass yourself even further I suggest you read this thread. The Last Moon Hoax Thread Ever. When you have read and understood it all I will answer any other questions you may have.
Also, the 1202 reference was inspired. |
