The official Google Earth plugin is one free download that makes all sorts of cool stuff possible in your browser. There's a full screen version of the program (complete with underwater views and 3D buildings) which can be searched by entering queries at the end of the URL. There's a framed version with support for layers, historical imagery, day/night cycles, and the Google Sky starmap. Less useful but more fun are Google's collection of "experiments" demonstrating the possibilities of the Earth API, including a "Geo Whiz" geography quiz, an antipode locater, a 3D first-person view of San Francisco, a virtual route-follower, and MONSTER MILKTRUCK!, a crazy fun driving simulator that lets you careen a virtual milk truck through the Googleplex campus, ricochet off the Himalayas, or explore any other place you care to name. Lots more can be found in the Google Earth Gallery -- highlights include a look at mountaintop removal mining, a real-time flight tracker, a guide to trails and outdoor recreation, a 360 panorama catalog, geotagged Panoramio photos, and the comprehensive crowdsourced Google Earth Community Layer. And while it's too large to view online, don't miss loading the Metafilter user location map into a desktop version of Google Earth! [more inside]
It is a stunning image and one that is bound to be reproduced over and over again whenever they recall the history of the US space shuttle.
On May 16, 2011, after one scrubbed attempt, the space shuttle Endeavour set off on her final mission, STS-134. Shuttle commander Mark Kelly had this to say after receiving a "go" from the launch poll:
On this final flight of space shuttle Endeavour, we want to thank all the tens of thousands of dedicated employees that have put their hands on this incredible ship and dedicated their lives to the space shuttle program. As Americans, we Endeavour to build a better life than the generation before, and we Endeavour to be a united nation. In these efforts, we are often tested. This mission represents the power of teamwork, commitment, and exploration. It is in the DNA of our great country to reach for the stars and explore; we must not stop. To all the millions watching today, including our spouses, children, family, and friends, we thank you for your support.You've seen launches before, but NASA has uploaded a whole slew of angles that will truly amaze: Witness 4.4 million pounds of shuttle, fuel, and rocket boosters "twang" a full 18 inches as the main engines ignite. 1.2 million pounds of thrust push against a locked down stack, waiting for the solid rocket boosters to ignite. (The SRBs bring the total to 7 million lbs of thrust, enough to break all that binds her to the pad.) OTV Camera 71, a fantastic, short close-up. UCS-15 (TV-21A) provides a dead-on, close up shot of the launch. The South Beach Tracker shot offers a fantastic view as well. From 3.1 miles away at the Press Site, note the ~11 second delay before the piercing sound of the SRBs hits. And just released today, fantastic footage from the solid rocket boosters, including their trip to splashdown in the Atlantic ocean from 30 miles up. And finally, the classic NASA view, with some great data overlays by Spacevidcast. [more inside]
50 years ago today, on May 25 1961, US President John F. Kennedy decided "...this nation should commit itself to achieving the goal, before this decade is out, of landing a man on the Moon and returning him safely to the Earth." Eight years later the Apollo program fulfilled the task, leaving the world with a legacy that includes advances in computers and communciation, lessons in managing complex projects, technological innovations and new views of the Earth.

Croatian software developer and amateur image processor Gordan Ugarković takes images from NASA's unmanned space probes released to the Planetary Data System, splices them together and tweaks the colors, sometimes combining higher resolution black and white images with color images, sometimes recreating what the object would look like in natural color (ie, in visible wavelengths, from images taken in multiple wavelengths), sometimes heightening the contrast to bring out detail.

The concept of time as a way to measure the duration of events is not only deeply intuitive, it also plays an important role in our mathematical descriptions of physical systems. For instance, we define an object’s speed as its displacement per a given time. But some researchers theorize that this Newtonian idea of time as an absolute quantity that flows on its own, along with the idea that time is the fourth dimension of spacetime, are incorrect. They propose to replace these concepts of time with a view that corresponds more accurately to the physical world: time as a measure of the numerical order of change.

First Orbit. "On 12th April 2011 it will be 50 years to the day since Yuri Gagarin climbed into his space ship and was launched into space. It took him just 108 minutes to orbit Earth and he returned as the World's very first space man. To mark this historic flight we have teamed up with the astronauts onboard the International Space Station to film a new view of what Yuri would have seen as he travelled around the planet. Weaving these new views together with historic voice recordings from Yuri's flight and an original score by composer Philip Sheppard, we have created a spellbinding film to share with people around the World on this historic anniversary."

As they leave the solar system, the Pioneer spacecraft have anomalously decelerated, pointing to a possible gap in our understanding of gravity. Now, a computer graphics technique known as Phong shading predicts that the Pioneer anomaly is just a side effect of how the shape of the spacecraft reflects sunlight.
The Van Allen Belt is a pesky radioactive torus surrounding Earth. Spacecraft operating for extended periods within it must use heavy and expensive radiation hardening techniques just to survive. Tethers Unlimited has proposed a rather daring scheme for circumventing this nuisance: HiVOLT. [more inside]
In 1967, Cosmonaut Vladimir Komarov went up in a capsule he knew would never get back (NSFW gruesome image) to earth in one piece. He could have bowed out of the mission, but that would meant his good friend, Yuri Gagarin (the first man in space) would have drawn the mission instead. So Vladamir launched knowing it was a suicide mission. The CIA was listening in , and recorded what may have been Vladimir Komarov's last words, amid cries of rage. Adding to the tragedy, Yuri died in a plane crash the next year.
"The Earth tide is a little-known daily event, similar to the oceans' more familiar tides. But the sun and moon's gravity doesn’t just pull on water, it deforms the Earth itself, causing the ground beneath us to bulge toward the pulling heavenly body." [more inside]
You Never Get a Seventh Chance to Make a First Impression: An Awkward History of Our Space Transmissions
Dr. Hoover has discovered evidence of microfossils similar to Cyanobacteria in freshly fractured slices of the interior surfaces of the Alais, Ivuna, and Orgueil CI1 carbonaceous meteorites. The scientist's conclusion is that the fossilized bacteria are not Earthly contaminants but are the fossilized remains of living organisms which lived in the parent bodies of these meteors, e.g. comets, moons, and other astral bodies. The implications are that life is everywhere, and that life on Earth may have come from other planets.

Apollo 14, with Alan Shepard, American's first man in space, as the Commander, Stuart Roosa, Command Module Pilot and Edgar Mitchell, lunar module pilot, splashed down forty years ago today. It was flight of the rookies (total previous time in space was 15 minutes, all by Shepard). There were several odd things about the flight, but no need to worry, the moon trees are doing just fine.
Several months ago, Bill Rankin of Radical Cartography (previously and previouslier) created an astronomical calendar of events for New Haven, Connecticut, where he lives, featuring all of the inexorable rhythms of the Solar System in one handy PNG file. Now you can create such a calendar for any location on the planet, with information as basic as the hours of daylight or as esoteric as the tilt of Saturn's rings, all lovingly rendered in soothing translucent pastels.

"The theme of this blog is not only and obviously space, but in particular places in space that a person might theoretically be able to one day visit. So for the most part, nebula, galaxies and the like are not a part of this forum. I tend to focus on “terrestrial” places or places that host such places. I suppose I would like to find out more about these places that we may one day inhabit or simply visit."

Slate says putting more than one space between sentences is "totally, completely, utterly, and inarguably wrong." Microsoft's Bill Hall agrees. LaTex does not. The American Psychological Association used to agree but has changed its mind. The exhaustive Wikipedia article on sentence spacing has a predictably prickly discussion page.
One of the most enduring mysteries in solar physics is why the Sun's outer atmosphere, or corona, is millions of degrees hotter than its surface. - Now scientists believe they have discovered a major source of hot gas that replenishes the corona

Dmitar Sasselov is an astrophysicist, Director of the Origins of Life Initiative at Harvard and a co-investigator of the Kepler space telescope project to find Earth-like planets around the Cygnus constellation and discover extraterrestrial life. But no matter how successful the Kepler project may be, it still won't answer the most fundamental questions of astrobiology: How diverse is life in the universe? If alien life exists, will it have Earthly DNA and proteins? Or will it run on something else? So Dr. Sasselov has decided to collaborate with two synthetic biologists, asking them to create a life form based on mirror-image versions of what we know as the essential building blocks of living things on Earth.

A hot carbon-rich gas giant exoplanet, WASP-12b, has been discovered. As the lead author of the paper being published today, Nikku Madhusudhan, says: ""This planet reveals the astounding diversity of worlds out there". In particular, the discovery supports theories that there are likely to be planets made of diamond and graphite out there.
