Space Settlements / spreading life throughout the solar system
"I know that humans will colonize the solar system and one day go beyond." Mike Griffin, former NASA Administrator.
A billion years ago there was no life on land. In a phenomenal development, by 400 million years ago land life was well established. We are at the very beginning of a similar, perhaps even more important, development. Today Earth teems with life, but as far as we know, in the vast reaches of space there are only a handful of astronauts, a few plants and animals, and some bacteria and fungi; mostly on the International Space Station. We can change that. In the 1970’s Princeton physicist Gerard O’Neill, with the help of NASA Ames Research Center and Stanford University, discovered that we can build gigantic spaceships, big enough to live in. These free-space settlements could be wonderful places to live; about the size of a California beach town and endowed with weightless recreation, fantastic views, freedom, elbow-room in spades, and great wealth. In time, we may see millions of free-space settlements in our solar system alone. Building them, particularly the first one, is a monumental challenge.
The Horsehead Nebula, a part of the optical nebula IC434 and also known as Barnard 33, was first recorded in 1888 on a photographic plate taken at the Harvard College Observatory. Its coincidental appearance as the profile of a horse’s head and neck has led to its becoming one of the most familiar astronomical objects. It is, in fact, an extremely dense cloud projecting in front of the ionized gas that provides the pink glow so nicely revealed in this GIF.

Given all of the recent coverage on the radical idea that the universe is one massive hologram, we thought we would take a few minutes to delve into what that really means for us. Basically, the holographic universe principle suggests that we’re living in a simulated reality (different from the hypothesis that states we live in a computer simulation), where our physical world is nothing more than a detailed illusion. This illusion is actually projected by our brains, as energy fields are being decoded into the seemingly 3 dimensional universe we see around us. In a more speculative sense, the theory suggests that the entire universe can be seen as a two-dimensional information structure, which is “painted” on the cosmological horizon, such that the three dimensions (four, if you include time) we observe are only an effective description at macroscopic scales and at low energies.
I’ve been thinking for some days now, what would be my greeting post for blog’s come back from the long vacation.
I’ve been thinking that I wanted to share an experience, something I saw during these days, and surprised me at such a level that I would like to share it here with you… Then again, everything would be like just another post.
Then I thought, what really amazed me this summer and in this year so far was the night sky.
a greeting post with a variety of videos inspired by the moon…
a suggestion for you that are staying home, this Sunday night…
Fantastic Planet (French: La Planète sauvage) is a 1973 cutout stop motion science fiction allegorical film directed by René Laloux, production designed by Roland Topor, written by both of them and animated at Jiří Trnka Studio…
An enormous hurricane raging at Saturn’s north pole has an eye 2,000km (1,250mi) across - big enough to cover the UK 12 times over.
The striking images of the storm were snapped from a height of 420.000km (260,000mi) by the Cassini spacecraft, which arrived at Saturn in 2004.
They were captured in red and infrared wavelengths and have been false-coloured to show detail.
Remember our previous video post on our sub-blog on space OVERVIEW?
OVERVIEW is actually the prelude to Planetary Collective’s forthcoming project CONTINUUM, a feature documentary film about our deep interdependence with each other, the planet and the universe. They tell us that this perspective is the key to understanding the grave crises we currently face as a civilisation and as a planet. If you haven’t seen the trailer yet, here it is (video above)…
Planetary Collective a team of three self-taught filmmakers who took a chance, quit their jobs, and have been living in the back of trucks and on people’s floors for nearly two years in order to make this film a reality. And with your support in this final phase they will be able to launch the film in February, 2014. If you haven’t seen the project, please check out the Kickstarter page and make a pledge. There are only 12 days left in the campaign, so please do so before March 24th.
Explanation: The Whirlpool Galaxy is a classic spiral galaxy. At only 30 million light years distant and fully 60 thousand light years across, M51, also known as NGC 5194, is one of the brightest and most picturesque galaxies on the sky. The aboveimage is a digital combination of a ground-based image from the 0.9-meter telescope at Kitt Peak National Observatory and a space-based image from the Hubble Space Telescope highlighting sharp features normally too red to be seen. Anyone with a good pair of binoculars, however, can see this Whirlpool toward the constellation of the Hunting Dogs (Canes Venatici. M51 is a spiral galaxy of type Sc and is the dominant member of a whole group of galaxies. Astronomers speculate that M51’s spiral structure is primarily due to its gravitational interaction with a smaller galaxy just off the top of the image.
Echolab is a studio specialized in sound design. They have imagined with the motion design studio Korb what would the spread of sound be like on Mars. The result is simply amazing, both for visuals and sounds.
A gale is very strong wind. Gale is also a crater on Mars where NASA Curiosity rover landed on August 2012. It is the most advanced mobile robotic science lab ever to explore another planet. The rover aims to behave for a Martian year, but the nuclear power source may last for 14 years. What does the future hold for Curiosity? Will Mars rover ever leave Gale Crater?
Astronomers have conclusively measured the spin of a black hole for the first time by detecting the mind-bending relativistic effects that warp space-time at the very edge of its event horizon — the point of no return, beyond which even light cannot escape.
