Title Forensic Evidence of a Galactic Collision
Description Astronomers have new evidence that the Andromeda spiral galaxy was involved in a violent head-on collision with the neighboring dwarf galaxy Messier 32 (M32) more than 200 million years ago. Infrared photographs taken with NASA's Spitzer Space Telescope revealed a never-before-seen dust ring deep within the Andromeda galaxy. When combined with a previously observed outer ring, the presence of both dust rings suggests that M32 plunged through the disk of Andromeda along Andromeda's polar axis approximately 210 million years ago. This image was obtained by the Infrared Array Camera (IRAC) at a wavelength of 8.0 microns.

Hubert Curien
Description Hubert Curien
Full Description Hubert Curien was born on 30 October 1924 in the Vosges region of eastern France. While a student, he enlisted in the French resistance and was commended for bravery in action. He entered the Ecole Normale Supérieure in Paris and went on to pursue a research career in crystallography, joining the Sorbonne Mineralogy Laboratory. He was always keen to encourage collaboration between mineralogists and physicists. He was appointed lecturer at the University of Paris in 1949, obtained his PhD in 1951, and became professeur in 1956. From 1968 onwards, he continued with his teaching career at the 'Pierre et Marie Curie/Paris VI' University, which he left only in 1994, despite all his political duties. Aside from his scientific career, Hubert Curien is known mostly for his managerial and political responsibilities, pursued with commitment, efficiency and vision both in France and in Europe. He left his mark on an impressive number of scientific institutions. From 1966 to 1969, he was Scientific Director for Physics at the CNRS, France's scientific research centre, becoming its Director General in 1969. In 1973, he was given responsibility for reorganising research in France. From 1976 to 1984, he was President of the French space agency (CNES), and from 1984 to1993, served as Minister of Research and Space under four different governments. From 1981 to 1984, he was Chairman of the ESA Council, and he is now still remembered ¿ among his many achievements ¿ as one of the fathers of the Ariane programme and as a promoter of a Europe united through science. From 1994 to 1996, he also headed the European Organization for Nuclear Research (CERN), and in 1993, was elected to the French Academy of Science. For his work, Hubert Curien received the highest distinctions and awards. He was known for his great intelligence and managerial and political abilities, but also for his simplicity, modesty, sense of humour and willingness to listen to others. He died on 6 February 2005, and is survived by his wife, Perrine, and their sons, Nicolas, Christophe and Pierre-Louis. *Credits:* ESA

Saturn's Radio Rotation
Description Radio waves produced near the poles of Saturn have been monitored by Cassini's Radio and Plasma Wave Science instrument (RPWS) since 2003.
Full Description Radio waves produced near the poles of Saturn have been monitored by Cassini's Radio and Plasma Wave Science instrument (RPWS) since 2003. A team of European scientists have analysed several years of Cassini RPWS data to study the variations of Saturn's radio clock, or its large fluctuations, at a 1-2 percent level, over weeks to months. They have found that the variation in the solar wind speed near Saturn is probably responsible for the poor stability of the planet's radio clock. interestingly, the solar wind speed does not vary randomly, but instead, follows a saw-tooth pattern, first building up in speed and then suddenly slowing down, and causing thus apparent rotation period fluctuations.

N81 in the Small Magellanic …
Title N81 in the Small Magellanic Cloud
Full Description A NASA Hubble Space Telescope "family portrait" of young, ultra-bright stars nested in their embryonic cloud of glowing gases. The celestial maternity ward, called N81, is located 200,000 light-years away in the Small Magellanic Cloud (SMC), a small irregular satellite galaxy of our Milky Way. Hubble's exquisite resolution allows astronomers to pinpoint 50 separate stars tightly packed in the nebula's core within a 10 light- year diameter - slightly more than twice the distance between earth and the nearest star to our sun. The closest pair of stars is only 1/3 of a light-year apart (0.3 arcseconds in the sky). This furious rate of mass loss from these super-hot stars is evident in the Hubble picture that reveals dramatic shapes sculpted in the nebula's wall of glowing gases by violent stellar winds and shock waves. A pair of bright stars in the center of the nebula is pouring out most of the ultraviolet radiation to make the nebula glow. Just above them, a small dark knot is all that is left of the cold cloud of molecular hydrogen and dust the stars were born from. Dark absorption lanes of residual dust trisect the nebula. The nebula offers a unique opportunity for a close-up glimpse at the firestorm' accompanying the birth of extremely massive stars, each blazing with the brilliance of 300,000 of our suns. Such galactic fireworks were much more common billions of years ago in the early universe, when most star formation took place. The "natural- color" view was assembled from separate images taken with the Wide Field and Planetary Camera 2, in ultraviolet light and two narrow emission lines of ionized Hydrogen (H-alpha, H-beta).

Theodore von Karman
Title Theodore von Karman
Full Description Dr. Theodore von Karman, co-founder of the Jet Propulsion Laboratory (JPL) Pasadena, California was an aeronautical theoretician. His contributions in the fields of aerodynamics and aeronautical engineering are well documented and well known to every aerospace engineer. He was the first winner of the prestigious U.S. Medal of Science presented to him by President John F. Kennedy. As well as being co-founder of JPL, he also was principal founder of a major rocket propulsion firm (Aerojet-General Corp.), the top science advisor to the U.S. Air Force during its transition to jet propulsion aircraft and the top science advisor to NATO. He was, during much of this time, the fountainhead of aerodynamic thought as head of the Guggenheim Aeronautical Laboratory at the California Institute of Technology (GALCIT) in Pasadena, California. In the May 1956 issue of the Journal of Aeronautical Sciences, it was said of him that "No other man has had so great an impact on the development of aeronautical science in this country. Hundreds of young men became his students and scientific collaborators and were inspired to greater effort." Dr. William H. Pickering, then director of JPL said in 1960 "We wouldn't have an aeronautical science as we know it today, if it weren't for Dr. Thoedore von Karman." Under his guidance, Caltech's 10 foot wind tunnel was designed, built and operated. Industry firms such as Douglas, Northrop, Hughes, Lockheed, North American, Vultee and Consolidated all tested new aeronautical designs and concepts in GALCIT's tunnel. Even Boeing's own high-speed wind tunnel was heavily influenced by suggestions from von Karman. The National Advisory Committee for Aeronautics (NACA) became so concerned about GALCIT's growing influence over West coast aviation, it erected the Ames Laboratory in Sunnyvale, California in part to deter an ever widening aeronautical gap that had formed between NACA and GALCIT. From 1936 to 1940, Caltech stood alone as the only university-based rocket research center. Von Karman gambled his prestige by supporting Frank Malina and H.S. Tsien's work on rocketry. Other institutions of higher learning dismissed such research as 'fantastical' and left such endeavors to visionaries like Robert Goddard. Foundational theoretical research by Von Karman gave rise to the first successful solid-fuel rocket engine firings. This led to federal funding for studies that lead to a form of aircraft rocket propulsion called Jet Assisted Take-Off or (JATO). Success in this endeavor led to von Karman establishing two more highly regarded institutions, both originally dedicated to rocketry: the Aerojet Engineering Company and the Jet Propulsion Laboratory. The last years of his life were spent in Paris, his favorite city. His interest in aeronautical research and contributions to it never waned. He organized in Paris the NATO Advisory Group for Aeronautical Research and Development (AGARD). Staffed by American and European scientists eager to, serve, its many committees investigated such disciplines as propulsion, aerodynamics and electronics. The legacy of his personable leadership and 'soft touch' approach to problem solving was only equalled by his genius.

Title Wright Flyer Test Flights at Fort Myer, VA
Full Description The Wright Flyer demonstrations at Fort Myer, Virginia on September 3, 1908. In January 1907 the Wright Brothers submitted a bid to the U.S. War Department to design a plane for $25,000. This bid came as a response to a War Department request issued a month earlier for a "Heavier-than-air Flying Machine." While Wilbur Wright went off to Paris to promote the Wright Flyer, Orville Wright stayed in Dayton, Ohio to design a plane for the Army Signal Corps. By August Orville's plane was ready and he headed to Fort Myer, Virginia, where the air trials were to take place. From August 20, 1908, to September 17, 1908, Orville performed test flights for the Army. On September 17th a split propeller caused the plane to crash, injuring Orville and killing his passenger, Lieutenant Thomas Selfridge. In spite of the crash the Army believed that the Wright plane would work. In July 1909, when Orville was able to fly again, he completed the test flights and surpassed all of the Army's requirements for a military plane: to carry a passenger for at least 125 miles at a speed of 40 miles per hour and stay aloft for at least one hour, easily transportable, controllable and steerable at all times and in all directions, and land without damage. On August 2, 1909, the Signal Corps accepted the Wright Flyer as the world's first military aircraft, naming it Signal Corps Airplane No. 1.

An unprecedented chart shows …
Description An unprecedented chart shows the true direction and apparent speed of a breeze of atoms, mainly hydrogen, that comes from the stars and blows right through the Solar System. In the solar spacecraft SOHO, built by the European Space Agency, the SWAN instrument detects a characteristic ultraviolet glow filling the sky, coming from the hydrogen atoms. Small shifts in the ultraviolet wavelength reveal the speed of the breeze. On a map of the whole sky, the windspeed is shown in relation to the direction from the Sun. A high negative velocity shown in purple depicts the incoming breeze, while in the orange parts of the chart the interstellar atoms are on their way out of the Solar System. In intermediate sectors they are moving sideways in relation to the Sun, so the radial speed is close to zero. White holes in the image are stars in the Milky Way emitting the same ultraviolet wavelength. An analysis based on two years of observations with SWAN defines the direction of the interstellar breeze more accurately than ever before. The source lies in the direction of the constellation Ophiuchus, close to Scorpius, and the night side of the Earth faces the breeze directly on 3 June each year. The SWAN instrument was provided for SOHO by the CNRS Service d'A[e/]ronomie at Verri[e\]res near Paris and the Finnish Meteorological Institute in Helsinki. SWAN has already charted the destruction (ionization) of interstellar hydrogen atoms by the impact of the solar wind coming from the Sun. Downwind of the Sun, they are almost entirely destroyed. That explains the difference in apparent windspeed, incoming and outgoing. The outgoing atoms detected in this study are far away, and have survived by giving the Sun a wide berth. They give a truer measure of the windspeed than the incoming atoms, which are accelerated by the Sun's gravity. Built in Europe for the European Space Agency, SOHO carries twelve sets of instruments provided by European and American investigators and it was despatched into space on 2 December 1995 by a NASA launcher. SOHO is a project of international cooperation between ESA and NASA. Credits: Main image: SOHO (ESA & NASA) and SWAN Consortium Star image: DSS/STScI/NASA
