PPT-How Do Astronomers Learn About the Universe?

The stars and other objects in space are very far from Earth Only a few solar system objects are close enough to be explored with probes Astronomers rely on electromagnetic waves to gain information about the universe.

Imagine that it’s 5,000 years ago, and you are alive….. Clocks and modern calendars have not yet been invented…. How would you know what time it is????. How would you know that your birthday is just a week away???. The Milky Way Galaxy. When you look into the hazy band of light across the sky, you are actually looking at our galaxy from the inside. While an awesome sight, you can only truly begin to see it if you get away from city lights on a moonless night. . 5 who made contributions to the study of gravitation and orbits. Galileo Galilei. David Arnold, Griffin Stofer, Meryl Seah . Period 2. Short Biography. Born in Pisa, Italy on February 15, 1564. Family belonged to nobility but not rich. OUR PLACE IN SPACE. Earth is not special. We do not have any unique place in the Universe. We live on an ordinary rocky planet called Earth, one of nine known planets orbiting an average star called Sun. We are near the edge of a huge collection of stars called the Milky Way Galaxy, which is one galaxy among countless billions of other galaxies spread throughout the observable universe..

This is the unique story of observing a total solar eclipse for no less than 74 consecutive minutes. On the summer morning of June 30, 1973, the Sun rises on the Canary Islands. But it is strangely indented by the Moon. The eclipse of the century has just begun. From the west, the lunar shadow rushes to the African coast at a velocity of over 2000 kilometers per hour. Astronomers on the ground will enjoy seven short minutes of total eclipse to study the solar corona - too short for Pierre Lena and seven scientists who board the Concorde 001 prototype, an extraordinary plane to become the first commercial supersonic aircraft. With Andre Turcat as chief pilot and a crew of five, at 17000 m altitude, the aircraft remains in the lunar shadow for 74 minutes, a record time of scientific observations not yetbeaten and allowing for exceptional measurements. Science, technology, aviation and history combine in the story of a unique human adventure aboard a legendary aircraft, illustrated with a rich and original iconography. It reflects the wonderful domains that science and technology can open, and the passion in the professions they offer. A must read for every eclipse chaser and fan of true scientific adventures.On the summer morning of June 30, 1973, the Sun rises on the Canary Islands. But it is strangely indented by the Moon.

Space tourism is fast becoming a reality. Ordinary people around the world are starting to wonder if they could really go to space and what it would be like - among them, many amateur astronomers. Here, the author explains the basics of what is involved in getting into space, from building the rocket and choosing where to go, to planning the mission and getting home again. The beauty of this text, written by an engineer who is also an accomplished science writer, is that it covers the subject comprehensively, and yet is almost entirely descriptive and non-mathematical. It deals with all aspects of space flight, from how to leave the Earth (including the design of the rocket, mission planning, navigation and communication), to life in space and the effects of weightlessness. The book also includes sections describing how an amateur can track satellites and understand their orbital parameters, and on the future of space flight, touching on what is and what is not possible given the present and predicted propulsion technologies. From newborn galaxies to icy worlds and blazing quasars, a behind-the-scenes story of how Palomar Observatory astronomers unveiled our complex universe.Ever since 1936, pioneering scientists at Palomar Observatory in Southern California have pushed against the boundaries of the known universe, making a series of dazzling discoveries that changed our view of the cosmos: quasars, colliding galaxies, supermassive black holes, brown dwarfs, supernovae, dark matter, the never-ending expansion of the universe, and much more. In Cosmic Odyssey, astronomer Linda Schweizer tells the story of the men and women at Palomar and their efforts to decipher the vast energies and mysterious processes that govern our universe.Palomar was the Apollo mission of its era. The first images from the 200-inch George Ellery Hale telescope, commissioned in 1948 as the world\'s largest, generated as much excitement as images from the moon in 1969 and from the Hubble Space Telescope more recently. So far, Palomar\'s Big Eye and three other telescopes have yielded more than 75,000 telescope-nights of precious data. Schweizer takes readers behind the scenes of scientific discovery, mapping the often chaotic process of detours, dead ends, and serendipitous leaps of insight. Although her focus is on Palomar, she follows threads of discovery across the world to other teams and observatories. Based on more than one hundred interviews and enhanced by research in scientific journals, her account paints a fascinating picture of how discrete insights acquired over decades by researchers in a global community cascade, collide, and finally coalesce into the discoveries we come to accept as facts.

Stars seem to move but Earth is actually moving west to east. So objects in the sky seem to rise in the east & set in the west . North star, Polaris is above North Pole and stars around it seem to form a circle-always present in Northern hemisphere.
