Showing results for "Exoplanets" in Science

Since its 2009 launch, the Kepler satellite has discovered more than 2,000 exoplanets, or planets outside our solar system. More exoplanets are being discovered all the time, remarkable in their variety. Astronomer Michael Summers and physicist James Trefil explore these remarkable recent discoveries: planets revolving around pulsars, planets made of diamond, planets that are mostly water, and numerous rogue planets wandering through the emptiness of space.

Technologically there's never been a better time to search for a new earth beyond our solar system.

As recently as 1990, it seemed plausible that the solar system was a unique phenomenon in our galaxy. Thanks to advances in technology and clever new uses of existing data, now we know that planetary systems and possibly even a new Earth can be found throughout galaxies near and far.

Astronomers have recently discovered thousands of planets that orbit stars throughout the Milky Way. Much of what has captured the imagination of planetary scientists and the public is the unexpected strangeness of these distant worlds. The quest to find other worlds brims with possibility, and Donald Goldsmith presents the science of exoplanets and the search for extraterrestrial life in a way that even Earthlings with little to no background in astronomy or astrophysics can understand and enjoy.

In the two decades since astronomers first discovered the existence of a planet outside of our solar system, “exoplanetology” has become the hottest specialty in astrophysics. Scientists young and old, inspired by the thought of finding either another habitable world or the Holy Grail of space exploration - life itself - flocked to be part of this burgeoning field. With so much brainpower on hand, it’s no wonder that investigative techniques advanced more quickly than anyone would have thought.

For centuries, people have speculated about the possibility of planets orbiting distant stars, but only since the 1990s has technology allowed astronomers to detect them. At this point, more than five thousand such exoplanets have been identified, with the pace of discovery accelerating after the launch of NASA’s Transiting Exoplanet Satellite Survey and the Webb Space Telescope. In The Little Book of Exoplanets, Princeton astrophysicist Joshua Winn offers a brief and engaging introduction to the search for exoplanets and the cutting-edge science behind recent findings.

Have you ever wondered what lies beyond our solar system? Are there other planets like Earth out there? How do we find them and study them? What can they teach us about ourselves and our place in the universe? If you are curious about these questions, then Exoplanet Radio is for you. We will explore the fascinating field of exoplanets, the planets that orbit other stars. We will learn about the history and methods of exoplanet discovery, the diversity and characteristics of exoplanets, the challenges and opportunities of exoplanet science, and the implications and prospects of exoplanet life. ...

Chris Impey conducts listeners across the vast, fast-developing field of astrobiology, surveying the dizzying advances carrying us ever closer to the discovery of life beyond Earth—and the prospect of humans living on another planet. With a view spanning astronomy, planetary science, geology, chemistry, and biology, Impey provides a state-of-the-art account of what's behind this accelerating progress, what's next, and what it might mean for humanity's future.

On August 21, 2017, more than 10 million Americans will experience an awe-inspiring phenomenon: the first total eclipse of the sun in America in almost 40 years. In Sun Moon Earth, astronomer Tyler Nordgren illustrates how this most seemingly unnatural of natural phenomena was transformed from a fearsome omen to a tourist attraction. From the astrologers of ancient China and Babylon to the high priests of the Maya, Sun Moon Earth takes us around the world to show how different cultures interpreted these dramatic events.

It is now known that we live in a galaxy with more planets than stars. The Milky Way alone encompasses 30 trillion potential home planets. Scientists Trefil and Summers bring listeners on a marvelous experimental voyage through the possibilities of life-unlike anything we have experienced so far - that could exist on planets outside our own solar system.
