Strange Space Blobs
Modified from Falling Onto the Dark
European astronomers have recently discovered a primordial “blob” of dark matter more than 10 billion light-years away. This gigantic object is twice as large as the Milky Way, but it only emits as much energy as 2 billion suns. The astronomers think they’re seeing large quantities of gas falling into a clump of dark matter, which could go on to build a large galaxy like the Milky Way. The most likely scenario to account for its existence and properties is that it represents the early stage in the formation of a galaxy, when gas falls onto a large clump of dark matter.
The object is invisible in the images taken with various telescopes observing from the infrared to the X-ray wavebands, making it a very peculiar object indeed. It is also the only such object found by the astronomers in their survey. Over the last few years, astronomers have discovered in the distant Universe a few so-called ‘blobs’. These are rather energetic but under-luminous objects, of the size of or much larger than our Milky Way galaxy. Their exact nature is still unclear and several scenarios have been proposed to account for their existence.
Cassini’s Hunt for Atomic Oxygen
Modified from The Mysteries of Enceladus
NASA’s Cassini spacecraft has been on the hunt for atomic oxygen since it arrived at Saturn. It has been found! The source turned out to be a thin atmosphere of water vapor surrounding Saturn’s moon Enceladus. Cassini flew past the mysterious moon in July 2005 and discovered that large dark cracks around its southern pole were warm and spewing out water vapor and ice particles. Cassini is due for a second look in 2008 when it will make another close flyby. The cloud of oxygen the Cassini spacecraft encountered as it first approached Saturn turned out to be a calling card from another celestial presence, the tiny moon Enceladus. The oxygen was the first clue that much more is going on beneath Enceladus’ icy surface than it first appeared. Tracking down the oxygen’s source led scientists to a most unusual spot in the solar system, a place that may possess one of the rarest and most sought-after substances in the universe - liquid water.
Since Saturn’s rings are made mostly of water ice, it wasn’t surprising to find one ingredient of water, oxygen, in Saturn’s atmosphere. The oxygen scientists observed was in the form of single oxygen atoms, called atomic oxygen, like that in water, H2O. Observations in spring 2005 showed that something very odd was taking place on Enceladus. Cassini’s magnetometer showed that the moon had an atmosphere. Too small to have enough gravity to hold on to an atmosphere for very long, Enceladus had to have a steady source of gas, such as geysers, to keep an atmosphere going. The cosmic dust analyzer detected a stream of particles around Enceladus. The scientists wondered whether these particles could be coming from the moon or from Saturn’s E ring and if, perhaps, the moon itself might be the source of ice particles for the E ring. The mystery of the atomic oxygen was solved when scientists revealed that Enceladus has an internal heat source and is geologically active. Its geysers throw out enough water vapor and ice to maintain the moon’s atmosphere, feed the vast E ring, and decompose into clouds of oxygen like the one first spotted by Cassini on its way to Saturn. Not far beneath the moon’s snowy white surface may be large pools of liquid water, warmed by the same heat source that powers its geysers. Its potential for water puts Enceladus into an elite group of places where life could exist. The Cassini spacecraft will swing back in 2008 for another look.
Modified from Controlling robots that search for Mars life
A proposed future mission called ExoMars will search for traces of life on Mars. The ESA mission requires entirely new technologies for self-controlled robots, built-in autonomy and cutting-edge visual terrain sensors. The fourth decade of this century could see Europe participating in a manned mission to Mars. A human mission to the Red Planet would be a major, multi-year undertaking with ExoMars being a precursor to this mission. ExoMars is due for launch around 2011 and will explore the biological environment on Mars. Data from the mission will also provide invaluable input for broader studies of exobiology – the search for life on other planets. The main element of the mission is a wheeled, robotic rover vehicle, similar in concept to NASA's current Mars Rover mission, but having different scientific objectives and improved capabilities.
The rover will use solar arrays to generate electricity, and will travel over the rocky surface of Mars, transporting the first-ever lightweight drilling system, as well as a sampling and handling device, and a set of scientific instruments to search for signs of past or present life. Due to distance time-lag and complexity, ExoMars will self-navigate using 'smart' electro-optics to visually sense and interpret the surrounding terrain and will be capable of operating autonomously using intelligent onboard software. It would survey the ground with a 3D camera, create a digital terrain model, verify its present location, run internal simulations and then make an autonomous decision on the best path to follow.
Red Spot Junior
Modified from Red Spots Brush Past Each Other
Recent evidence shows Jupiter’s two giant red spots brushing past one another in the planet’s southern hemisphere. Astronomers have been predicting the close encounter for months; Jupiter’s Great Red Spot and its newly formed “Red Spot Jr.”. Both red spots are massive storm systems. Astronomers don’t think anything dramatic is going to happen as the storms slip past each other this time around. The top of the larger one, known for a long time as the Great Red Spot, lies about 5 miles above the neighboring cloud tops and is the largest hurricane known in the solar system. Red Spot Junior is roughly half the size of its famous cousin, but its winds blow just as strong. This mighty new storm formed between 1998 and 2000 from the merger of three long-enduring white ovals, each a similar storm system at a smaller scale, which had been observed for at least 60 years.
No one is certain why this white oval turned red. One theory is that the merger of the three white ovals led to an intensified storm system. This made it strong enough to dredge up reddish material from deeper in the atmosphere. As this material welled up in the middle of the spot, it is protected from escape by the strong circulating currents at the spot’s edges. Another popular hypothesis contends that the material dredged up from below Jupiter’s visible clouds climbs to an altitude where the Sun’s ultraviolet light chemically alters it to give it a reddish hue.
The white ovals from which Red Spot Junior is made have passed by the Great Red Spot countless times as the atmospheric current in which they are embedded moves at a different speed from the one at the latitude of the Great Red Spot. Each red spot is rotating with Jupiter at slightly different rates and over time, like passing cars on a highway, the two spots change relative positions causing periodic close passages like this. However, this is the first such passage since the new, smaller red spot intensified and turned red. Nothing dramatic is expected to happen as the two storm systems continue their close encounter. But future passages could always allow for the merger and formation of a “Red Spot Senior”.
