his was a very exciting and, at the same time, very surprising discovery. It was exciting because if true, it would have marked the detection of the first planet outside of our solar system. It was surprising because the planet-hosting star is the primary of a binary system with a separation less than 19 AU, a distance comparable to the planetary distances in our solar system.

Ebook "Giant planets of our solar system: Atmospheres, composition, and structure (Second edition)" reviews the current state of knowledge of the atmospheres of the giant gaseous planets: Jupiter, Saturn, Uranus, and Neptune. The current theories of their formation are reviewed and their recently observed temperature, composition and cloud structures are contrasted and compared with simple thermodynamic, radiative transfer and dynamical models.

The magnetosphere is an open system that interacts with the solar wind. In this system, solar wind energy continuously permeates different regions of the magnetosphere through electromagnetic processes, which we can well describe in terms of current systems. In fact, our ability to use various methods to study magnetospheric current systems has recently prompted significant progress in our understanding of the phenomenon.

The Earth is the only planet in our solar system that supports life. The complex process of evolution occurred on Earth only because of some unique environmental conditions that were present: water, an oxygen-rich atmosphere, and a suitable surface temperature. Climate change refers to a statistically significant variation in either the mean state of the climate or in its variability, persisting for an extended period (typically decades or longer).

Generating electricity from a heat source using no moving mechanical parts is the ultimate goal of the Defense Threat Reduction Agency’s thermionics program. However, developing thermionic energy conversion devices has proven difficult, although much progress has been made. In spite of initial success during the late 1960s and intermittent funding since that time, for a variety of reasons no thermionic system has yet been developed in the United States that can be used today on Earth or in space.

The novel is about a space voyage to Alpha Centauri, the nearest solar system to our own. It starts as a high tech voyage, and then becomes much more than that. It links up with a future that is moving backwards. It also comes upon a present that has no future, but for which a future is created that opens up a sphere without limits for humanity.

Four hundred years ago, the Universe changed. Or, at least, our perception of it did, thanks to Galileo Galilei’s scrutiny of the night sky with a telescope. Within a couple of years, his observations of the Moon, phases of Venus and satellites of Jupiter shattered the old Ptolemaic model of our Solar System. To the church’s dismay, Earth assumed its rightful place as one of several planets orbiting the Sun (see page 28). Marking Galileo’s anniversary, the International Year of Astronomy seeks to remind us of the humbling nature of gazing at the heavens.

The Moon is the nearest member of the Solar system to Earth. Humans from the earliest times have found the Moon to be an object of great interest and a source of speculation as to the meaning of the light and dark markings on its surface. The discovery of the telescope and its use by Galileo in 1610 to observe the Moon set these speculations at rest by revealing the true nature of the Moon’s surface. As telescopes improved so did our knowledge of the Moon’s features. The Moon is also the only body in the Solar system (apart from Earth itself) on which humans have visited and...

We are privileged to be living in one of the greatest eras of exploration that humankind has ever undertaken. Our current Age of Space grew out of the dark struggles of World War II when large rockets were developed as agents of mass murder. The subsequent Cold War rivalry between the United States and Soviet Union pushed rocket capabilities to the point that it became possible to send vehicles into Earth orbit and beyond (even though the stated aim was to send missiles carrying nuclear weapons over mere continental distances). The Russians put the first human into Earth orbit.

Every employee has a story at Cummins Power Generation. Some are stories of coming to work with a parent when they were young, becoming employees themselves, then watching their children as they carry on the legacy. Others tell of starting at a distributorship and moving on to one of the many Cummins Power Generation offices located around the world. Some tell of starting at a regional office, before moving to global headquarters. Others talk of their days as customers working for utility companies.

Astronomers have studied the heavens for more than two millennia, but in the twentieth century, humankind ventured off planet Earth into the dark vacuum void of space, forever changing our perspective of our home planet and on our relationship to the universe in which we reside. Our explorations of space—the final frontier in our niche in this solar system—first with satellites, then robotic probes, and finally with humans, have given rise to an extensive space industry that has a major influence on the economy and on our lives. In 1998, U.S.

Space research is one of the most evocative and challenging fields of human endeavour. In the half-century that has elapsed since the beginning of the space age, we have been exposed to wonders beyond the imagination of even the most visionary of science fiction writers. We have peered deep into the Universe and studied physics that we can never duplicate on the Earth. We have begun to understand our own Sun, and the flow of energy outward through the Solar System that is fundamental to our existence.
