Showing results for "Dark" in Astronomy & Space Science

How can we make intelligent decisions about our increasingly technology-driven lives if we don’t understand the difference between the myths of pseudoscience and the testable hypotheses of science? Pulitzer Prize-winning author and distinguished astronomer Carl Sagan argues that scientific thinking is critical not only to the pursuit of truth but to the very well-being of our democratic institutions.

All the matter and light we can see in the universe makes up a trivial five per cent of everything. The rest is hidden. This could be the biggest puzzle that science has ever faced. Since the 1970s, astronomers have been aware that galaxies have far too little matter in them to account for the way they spin around: they should fly apart, but something concealed holds them together. That ’something' is dark matter - invisible material in five times the quantity of the familiar stuff of stars and planets.

Host Lenny Vaughn explores why minor keys pierce the heart, examining the science of sad intervals, haunting transformations, and building sonic spaces for grief. A meditation on music's darkest frequencies and our need to sit with sorrow. For more content like this, visit QuietPlease.ai

In this brilliant exploration of our cosmic environment, the renowned particle physicist and New York Times best-selling author of Warped Passages and Knocking on Heaven's Door uses her research into dark matter to illuminate the startling connections between the farthest reaches of space and life here on Earth.

In the first book to critically assess the major consequences of space activities from their origins in the 1940s to the present and beyond, Daniel Deudney argues in Dark Skies that the major result of the "Space Age" has been to increase the likelihood of global nuclear war, a fact conveniently obscured by the failure of recognize that nuclear-armed ballistic missiles are inherently space weapons. 

Climate change has been a perplexing problem for years. Casey's research into the Sun's activity, which began almost a decade ago, resulted in discovery of a solar cycle that is now reversing from its global warming phase to that of dangerous global cooling for the next 30 years or more. This new cold climate will dramatically impact the world's citizens.

Dark matter, an elusive and invisible substance, constitutes a significant portion of the universe's mass, detectable only through its gravitational effects. First proposed by Fritz Zwicky in the 1930s and supported by Vera Rubin's observations in the 1970s, dark matter does not interact with light, making it invisible. Scientists explore its nature through various theoretical candidates like WIMPs, axions, and sterile neutrinos. While detection remains challenging, methods include underground labs, particle accelerators, and indirect observations. Ongoing research promises to unravel this ...

We now know that the universe is mostly dark, made up of particles and forces undetectable by our most powerful telescopes. The discovery signaled a Copernican-like revolution in astronomy: not only are we not the center of the universe, neither is the stuff of which we're made. Vera Rubin played a pivotal role in this discovery. By showing that some astronomical objects seem to defy gravity, Rubin helped convince the scientific community of the possibility of dark matter. In Bright Galaxies, Dark Matter, and Beyond, Ashley Jean Yeager tells the story of Rubin's life and work.

Marnie Ogg talks with some of the brightest minds in the field about light pollution and ways to protect our night skies.

On July 23, 1999, the Chandra X-Ray Observatory, the most powerful X-ray telescope ever built, was launched aboard the space shuttle Columbia. Since then, Chandra has given us a view of the universe that is largely hidden from telescopes sensitive only to visible light. In Chandra's Cosmos, Wallace H. Tucker uses a series of short, connected stories to describe the telescope's exploration of the hot, high-energy face of the universe.

In The Elephant in the Universe, Govert Schilling explores the fascinating history of the search for dark matter. Evidence for its existence comes from a wealth of astronomical observations. Theories and computer simulations of the evolution of the universe are also suggestive: they can be reconciled with astronomical measurements only if dark matter is a dominant component of nature.

Space is the biggest, oldest, hottest, coldest, strangest thing a human can study. It's no surprise then, that the weirdest facts in science (not to mention the weirdest scientists themselves) are found in astrophysics and cosmology. If you're looking for instructions on how to set up your grandad's telescope this book probably isn't for you. In Astronomical, Tim James takes us on a tour of the known (and unknown) Universe, focusing on the most-mind boggling stuff we've come across, as well as unpacking the latest theories about what's really going on out there.

In the vein of Randall Munroe's What If? meets Brian Green's Elegant Universe, a senior writer from Space.com leads readers on a wild ride of exploration into the final frontier, investigating what's really "out there." We've all asked ourselves the question. It's impossible to look up at the...

Behind every star and constellation is a story. Ever since human beings were able to articulate the world around them, they gazed up towards the stars and crafted myths, stories and legends about the night sky. Every creation story has an origin for the stars, sun and moon! Whether it's telling stories about the night or telling stories in the dark, it is a fundamental element of our cultural history, one which is shared the world over. Listen to folk tales and stories inspired by the night sky.
