Wright, a Scottish native living in England, is working to make his station more accessible to the public. He has proposed a redesign of the park area to integrate his research station with a 'Planet Path'. This path will feature a scaled representation of the solar system, allowing visitors to learn about the planets and Wright's work with radio telescopes. The article details the scientific principles of radio astronomy, explaining how it observes celestial objects by detecting radio waves, complementing optical observations. Wright, who studied electronics in England and built his 800 kg radio telescope with Angelika Gehrke, is dedicated to searching for extraterrestrial life by analyzing radio signals and supporting optical observations.

Was ist, was will, was kann Radioastronomie? (What is, What Does, What Can Radio Astronomy Do?)

This section provides a concise explanation of radio astronomy. It defines astronomy as an exact science that analyzes electromagnetic radiation from space, from visible light to radio waves. Radio astronomy, which began in 1932 with the reception of radio waves from the Milky Way, has developed significantly since 1945. Using radio telescopes, scientists can determine the composition, structure, and evolution of the universe. Radio astronomy offers a greater reach than optical observation and can detect objects that are obscured from optical view. The discovery of quasars in 1960 and pulsars in 1967 are highlighted as major achievements.

Andockmanöver macht ISS bewohnbar (Docking Maneuver Makes ISS Habitable)

This report details the successful docking of the Russian living and service module 'Swesda' (Star) to the International Space Station (ISS). The automated maneuver, conducted 370 kilometers above Earth, transformed the construction site into a habitable space station. The docking occurred on Wednesday morning, with the 'Sarja' and 'Unity' modules connecting with 'Swesda'. This event is described as a 'historic moment' by experts at the Russian mission control and NASA. The first crew, consisting of two Russians and one American, is scheduled to arrive on October 30th. Juri Koptew, head of the Russian Space Agency Rosaviakosmos, called the docking a 'decisive moment' in the ISS construction. The 'Swesda' module, completed two years behind schedule, was launched on July 12th. The ISS construction will continue with further Russian and American flights until 2004, culminating in the addition of the European research laboratory 'Columbus'.

Neuer Roboter soll Mars erkunden (New Robot to Explore Mars)

NASA is planning a new mission to Mars in 2003, which will involve deploying a robotic rover to explore the planet's surface. The 150 kg rover is designed to travel 100 meters per day and transmit color and infrared images back to Earth. It will also search for water, a discovery recently made on Mars. The mission aims to advance our understanding of the Red Planet.

Vor 407 Jahren starb ein Stern - jetzt können wir es beobachten (407 Years Ago a Star Died - Now We Can Observe It)

This article describes the observation of a supernova event from a star named 'Dschubba' (meaning 'Forehead' in Arabic) in the constellation Scorpio. The light from this stellar explosion, which occurred 407 years ago, is only now reaching Earth. Dr. Jakob Staude from the 'Sterne und Weltraum' institute explains that the star's gravitational force caused it to burn hydrogen into new elements, which were then ejected into space. The explosion is described as having 13 times the weight of the Sun, and its light will continue to be visible for a long time.

Der Mars macht die Nasa wieder mobil (Mars Makes NASA Mobile Again)

Following two unsuccessful missions, NASA has regained its confidence and announced an ambitious new Mars program. The plan is to send a lander-rover to Mars in three years, possibly followed by a second vehicle. This new rover will be a descendant of the successful 'Mars Pathfinder' of 1997, but will be significantly heavier (150 kg) and equipped with modern technology. The rover's mobility will be enhanced by a new drive system, and it is expected to cover 100 meters per day. The landing will utilize a system similar to 'Pathfinder', with strong air cushions to ensure a safe touchdown. The project is estimated to cost between $350 and $400 million. The recent discovery of relatively young water traces on Mars has reignited discussions about the possibility of life on the planet, providing a significant impetus for NASA's renewed Mars exploration efforts.

Eine neue Galaxie aus 4 Billionen Sonnen (A New Galaxy of 4 Trillion Suns)

This report features an image of a newly discovered galaxy, located 70 million light-years from Earth. The 'Very Large Telescope' (VLT) in Chile captured the image, showing a bright sphere of light. The galaxy is described as being at least twice the size of our Milky Way and containing four trillion suns. The article notes that the bright center suggests a high number of stars, possibly due to four thermonuclear stellar explosions that occurred when dinosaurs roamed Earth. Dark streaks around the light indicate dense dust and gas clouds where new stars are forming.

Planet im Hinterhof des Sonnensystems (Planet in the Backyard of the Solar System)

Astronomers have announced the discovery of nine new planets orbiting stars, indicating that many stars are accompanied by planets. The star Upsilon Andromedae, previously known to have two planets, now has a third. The star HD83443 has also been found to host two planets. These discoveries bring the total number of known exoplanets to 50. Astronomers believe that many more stars likely possess planets. The article mentions the discovery of an exoplanet around a star only 10.5 light-years from Earth. The International Astronomical Union (IAU) meeting in Manchester also discussed the ongoing search for exoplanets, with researchers noting that the pace of discovery is rapid.

Fische fallen vom Himmel (Fish Fall from the Sky)

A peculiar event occurred in an English coastal town where fish rained from the sky. This phenomenon was caused by a waterspout that lifted fish from the sea and then dropped them onto land as its energy waned. An eyewitness described the scene as unbelievable, with their backyard covered in silvery fragments.

Entdeckt! Ein Planet, der der Erde ähnelt (Discovered! A Planet Similar to Earth)

American researchers from the McDonald Observatory have discovered a new planet in a neighboring solar system that orbits the star Epsilon Eridani. The similarities between the Epsilon Eridani system and our own solar system suggest that this system might also harbor a planet capable of supporting life, similar to Earth. This discovery raises hopes for the existence of habitable worlds beyond our own.
