This image takes significant events from the timeline of the Space Race from 1957 through 1975 and plots them into a y-axis that gauges the relative significance of those accomplishments. All human spaceflight programs are graphed along with leading events for unpiloted probes. It is all put in context of government leadership and selected technological, social and military events of that period as they happened under the shadow of the nuclear arms race. Three separate flows are charted. The first being unpiloted space probes toward the lunar goal as they evolved from Sputnik/Explorer to the lunar impactors, landers, rovers and sample return missions. The second (but PRIMARY in significance) being human spaceflight from Gagarin/Shepard up to the pinnacle of the Apollo Moon missions and back down to the Salyut/Skylab stations, then cooling off with Apollo/Soyuz (not covering the continued story of Shuttle/Buran and Mir/ISS). The third flow, shown at the top of the chart, covers leading interplanetary probes as they attained certain goals with varying success. Ending the timeline at Apollo/Soyuz puts achievements such as the Viking landers and Voyager missions off to the right of this chart. The parenthetical years shown at the right edge of the chart mark when that particular level was accomplished by the other country, such as Sally Ride becoming the first U.S. female in space in 1983, twenty years after Valentina Tereshkova. (Minority and non-government breakthroughs that happen after the mid-70s timeframe are not shown in this chart.) Displaying these accomplishments graphically makes it easy to see how the U.S. started behind but eventually caught up and surpassed the Soviet Union. The U.S. was a year behind in getting a

Purple Haze, Part Deux A massive cluster of galaxies located about 2.3 billion light years away, Abell 1689, shows signs of merging activity. Hundred-million-degree gas detected by NASA's Chandra X-ray Observatory is shown as purple in this image, while galaxies from optical data from the Hubble Space Telescope are colored yellow. The X-ray emission has a smooth appearance, unlike other merging systems such as the Bullet Cluster or MACS J0025.4-1222. The temperature pattern across Abell 1689 is more complicated, however, possibly requiring multiple structures with different temperatures. The long arcs in the optical image are caused by gravitational lensing of background galaxies by matter in the galaxy cluster, the largest system of such arcs ever found. Further studies of this cluster are needed to explain the lack of agreement between mass estimates based on the X-ray data and on the gravitational lensing. Previous work suggests that filament-like structures of galaxies are located near Abell 1689 along our line-of-sight to this cluster, which may bias mass estimates using gravitational lensing.

The temperature of the liquid helium in this vacuum bottle is 2.2K(Lambda point) or less. There is no visible boiling (due to zero viscosity of superfluids). The liquid is in its Superfluid Phase.
When liquid helium is cooled down from 4.2K to the lambda point at 2.2K the liquid for a brief moment boils up violently.Suddenly, boiling ceases. This is the transition from the normal phase to the superfluid phase.
The liquid helium is in the superfluid phase. A thin invisible film creeps up the inside wall of the cup and down on the outside. A drop forms. It will fall off into the liquid helium below. This will repeat until the cup is empty - provided the liquid remains superfluid.

The simple event of a droplet impacting liquid is an everyday occurence in our immediate surroundings but the action all occurs so quickly that it's hard to appreciate the subtle beauty hidden in a brief instant like this. The image seen here depicts the split-second after the impact of some blue food dye into a saucer of milk. It was taken with the assistance of a Nikon SB-800 Speedlight flash, synchronised to a shutter capture time of 1/500th second. The original photograph is available in full resolution at this address.
