Portals to the universe

"A mission scientist with NASA's Kepler Space Telescope, Natalie Batalha hunts for exoplanets — Earth-sized planets beyond our solar system that might harbor life. She speaks about unexpected connections between things like love and dark energy, science and gratitude, and how "exploring the heavens" brings the beauty of the cosmos and the exuberance of scientific discovery closer to us all".

13 billion light-years from home

eXtreme Deep Field (1.4 MB JPG) is the deepest-ever view of the universe - a new assemblage of 10 years of Hubble Space Telescope photographs focused on a small area at the center of the original Ultra Deep Field. With a cumulative exposure time of 2 million seconds, XDF shows approximately 5,500 galaxies - some of them 10 billion times too faint to be seen with the naked eye.

How to Build a Computer Model of God

My assumption has always been: If something like a soul exists, and it affects our consciousness in any manner, then it must be detectable by some scientific device. I find it difficult to imagine that something can interact with my physical body without leaving any physical trace. But though I find it hard to imagine, is it possible for something like a soul to interact with me without leaving any physical trace?

What does a Higgsless universe mean for science?

What does a Higgsless universe mean for science? The Higgs Boson is quite important to the standard model of physics. If it exists, it plays a major role in explaining how particles acquire mass. There’s a distinct possibility that the Higgs Boson may not even exist. Stephen Hawking made a famous bet that the Large Hadron Collider (LHC) wouldn't find it. So far both the LHC and Tevatron, another massive particle accelerators have both searched much of the energy ranges we expected to find the Higgs with no luck. So, then, what does it mean if we don’t find the Higgs at all?

Dark Matter Haters to the Left

When we talk about dark matter and its alternatives, we are talking about no less a task than explaining the structure of every large object in the Universe. On the largest scales dark matter blows all of its competitors away. In terms of explaining the large-scale structure of the Universe, not a single one of dark matter's alternatives comes close to mirroring its success. But of course, that doesn't stop the sensationalist headlines from rolling in. We are understandably uncomfortable with the notion that we are not the most important thing in the Universe. We've just successfully figured out where the new material to form the Milky Way's young stars is coming from: high-velocity intergalactic gas clouds! About a Sun's worth of gas falls into the Milky Way (on average) every year, and this resupplies the Milky Way's gas reserves, which get eaten up as new stars form over billions of years. But what about the other, larger mystery? What about reproducing the structure of the Milky Way itself?

Planck unveils the Universe

Planck telescope reveals ancient cosmic light. "The picture is the first full-sky image from Europe's Planck telescope which was sent into space last year to survey the oldest light in the cosmos. It took the 600m-euro observatory just over six months to assemble the map. It shows what is visible beyond the Earth to instruments that are sensitive to light at very long wavelengths - much longer than what we can sense with our eyes." [more inside]

The Known Universe

The Known Universe takes viewers from the Himalayas through our atmosphere and the inky black of space to the afterglow of the Big Bang. Every star, planet, and quasar seen in the film is possible because of the world's most complete four-dimensional map of the universe, the Digital Universe Atlas that is maintained and updated by astrophysicists at the American Museum of Natural History. The new film, created by the Museum, is part of an exhibition, Visions of the Cosmos: From the Milky Ocean to an Evolving Universe, at the Rubin Museum of Art in Manhattan through May 2010.

It's full of stars

One of the hardest things for people to understand about the universe is just how big it is. There are three approaches typically used in describing its size. The first, the song, was pioneered by Monty Python (NSFWish, wireframe of naked woman) and then done just as masterfully by the Animaniacs. The second, the zoom method has been featured twice before here on the blue. The third method is the comparison method (skip to 1:30, unless you like looking at a image of the solar system with terrible distorted orbits), yielding some truly beautiful videos (this one found via the fantastic Bad Astronomy blog). These videos go, at most, as far as looking at the local cluster or the Virgo Supercluster. There are two videos that attempt to show the size of the entire universe, one unsuccessfully (although with great music) and one successfully. (Warning, all links except the first one, are to YT videos). [more inside]

New burst vaporizes cosmic distance record. "NASA's Swift satellite and an international team of astronomers have found a gamma-ray burst from a star that died when the universe was only 630 million years old, or less than five percent of its present age. The event, dubbed GRB 090423, is the most distant cosmic explosion ever seen."

Dark Flow

Mysterious New 'Dark Flow' Discovered in Space. "As if the mysteries of dark matter and dark energy weren't vexing enough, another baffling cosmic puzzle has been discovered. Patches of matter in the universe seem to be moving at very high speeds and in a uniform direction that can't be explained by any of the known gravitational forces in the observable universe. Astronomers are calling the phenomenon 'dark flow.' The stuff that's pulling this matter must be outside the observable universe, researchers conclude." [more inside]

The universe [flash]. I know, it's on a corporate site, and you have to sit through some pretentious Japanglish while it loads, but being able to use your mousewheel to scroll from femtometers up to the 100 billion lightyear scale is dazzling. I love cosmic zooms.

"The sun descending in the west, The evening star does shine;"

Have you ever wondered what a solar eclipse would look like from space? The STEREO (Solar TErrestrial RElations Observatory) has just sent back its view (awe-inspiring video included). It has also sent back some gorgeous pictures of our sun (and the McNaught Comet). For more media, check out the other galleries (including some 3D images). For more about the project, see NASA's STEREO homepage. Be sure to also stop by the Johns Hopkins University STEREO Page, where you can download a mission guide (pdf), view animations, watch a video of the launch, or even make your own papercraft STEREO model (pdf). You can also learn more in six minute segments with their series of short educational videos.

The Simulacrisation of Technology into Life

As the Pentagon ousts plans to turn insects into cyber war machines you'd be forgiven for asking the question: Where does the real digital end and the faked life begin? Are we simulating life synthetically? or just speeding up an entirely natural process? Technologically engineered life is here to stay. Its not far fetched to speculate that simulacra may become all there is.
