At that time, astronomers relied on grounded telescopes to record nightly observations of the stars. Women computers at the Harvard College Ovesrvatory were then tasked with interpreting those observations, captured on photographic glass plates. Author Dava Sobel follows the stories of several women, which she collected from old diaries, letters and published observatory log books.
For any space fan looking to learn crazy, fun facts about the universe, "Facts From Space!
Dean Regas, an astronomer and public outreach educator for the Cincinnati Observatory, has gathered together all the cool, quirky and mind-blowing facts you probably never knew you'd want to know about the universe. Regas chronicles everything from the sometimes silly adventures of space travelers in Earth's orbit and on the moon to black holes, galaxies and nebulas far away in deep space, listing all the best facts about the universe in a way that is fun and easy to read.
Readers of all ages can understand and appreciate the contents of this book. No attention span is necessary to enjoy it — flip to any page and you'll find a handful of short facts and cartoons that make learning about space a simple and entertaining experience.
Space and time are weird. All very straightforward, and good for scientific investigation. But the problem is, there are hints that nature doesn't actually work that way. This new book by science writer George Musser delves into the different ways that scientists are grappling with this concept of "nonlocality" — what Albert Einstein famously called "spooky action at a distance" in the quantum mechanics world. Particles that are entangled affect each other instantaneously even when separated; paradoxical black holes can be explained if the stuff sucked in exists inside their gravitational pull and on the surface at the same time.
Musser explores the history of humans grappling with nonlocality and what these strange effects are teaching quantum mechanics researchers, astronomers, cosmologists and more about how the universe works — and while doing so, showing the messy, nonlinear and fascinating way researchers push forward to understand the physical world. Theoretical astrophysicist Kip Thorne has spent his career exploring topics that once seemed relegated to science fiction, such as whether time travel is possible, and how humans could potentially travel from galaxy to galaxy via wormholes.
In "Black Holes and Time Warps," Thorne provides an introduction to these and other mind-bending topics, at a level appropriate for nonscientists. The book is not a light read — it goes deeper into the science than many pop physics books — but Thorne is the perfect person to take readers on this journey: He's a patient and entertaining teacher, and he never loses the thread of the story.
On top of the science lessons, Thorne introduces a cast of characters who pushed these fields forward, and chronicles the fight by American and Russian physicists to continue scientific collaboration during the Cold War. Twenty years after its publication, Thorne talked with Space. While some of it may seem dated, the book still stands up as one of the best popular science books ever written, and the language is just beautiful. Sagan was one of the 20th century's greatest ambassadors and popularizers of science, and he doesn't disappoint in "The Demon-Haunted World.
There's a lot of debunking in "The Demon-Haunted World" — of alien encounters, channeling and other paranormal experiences — and Sagan even provides readers a "baloney detection kit" to help them navigate a confusing and chaotic world. Like other Sagan works, this one is a fun and engaging read, but a great deal of ambition lurks beneath the fluid prose, as this quote from the book reveals: "If we can't think for ourselves, if we're unwilling to question authority, then we're just putty in the hands of those in power.
But if the citizens are educated and form their own opinions, then those in power work for us. In every country, we should be teaching our children the scientific method and the reasons for a Bill of Rights. With it comes a certain decency, humility and community spirit.http://phon-er.com/js/free/samsung-galaxy-s4-smart-scroll.php

In the demon-haunted world that we inhabit by virtue of being human, this may be all that stands between us and the enveloping darkness. Our brains evolved to comprehend the world around us on a local and accessible scale. We're really not equipped to understand the universe as a dimensional entity — and yet "Hyperspace" explains this revolutionary idea in such a lucid and engaging way that it makes a good deal of sense.
By the time you're done reading this book, you'll have a pretty solid grasp of why Kaku and other scientists think the basic forces in our universe — electromagnetism, gravity and the strong and weak nuclear forces — may actually just be vibrations in higher-dimensional space. And it's an extremely fun read, too, with excursions into such sexy topics as parallel universes, time travel and wormholes. For example, did you know that you might be able to create a wormhole in your own kitchen using just an ice cube and a pressure cooker?

The focus is on potential interactions between galaxies clustered closely together. How do diffuse interstellar gas clouds form, evolve and eventually collapse to form stars and planets? Their 3-D analyses recently uncovered an optical illusion that had not been detected with the previous 2-D analyses: The Gould Belt in the Milky Way is not actually a ring of stars but a projection effect.
As part of the international project, the researchers also created the first 3-D map of the regions around our Sun.
A New Approach
Their 3-D analysis also revealed the presence of enormous streams of young stars, traced by the massive but short-lived O- and B-stars. The data will allow them to reconstruct the regions near our Sun in a never before seen resolution and create accurate maps of stars and the interstellar gas between them. They will be able not only to reconstruct our galactic neighbourhood accurately but, by doing that, understand the origins of sun-like stars and the build-up of galaxies like our Milky Way. How do the properties of stars influence planets? Under what conditions do some proto-atmospheres survive on planets, and why do some evaporate?
What properties must a planet have to create suitable conditions for life and, in particular, liquid water? And how do all these factors have to interact to finally result in a habitable planet? Their goal is to gain a comprehensive view of the different factors and their interactions using modelling. His team is initially focusing on our solar system — particularly Earth with its neighbours Mars and Venus — as a field of study. In the case of Earth, its mass, insolation and the astronomical architecture of our solar system made life possible. However, the group is also studying extrasolar planetary systems with very different properties.
It is important to understand protoplanetary disks in order to understand where planets come from, how they form, grow and create their first atmosphere. Sun-like stars become pulsating red giants in their late evolutionary stages also called AGB stars. The red giants are characterised by expanding gas and dust envelopes, which enrich the interstellar space with heavy elements and solids. This process provides the raw material for star and planet formation. Research specialties: Modeling and data analysis of solar flares and coronal mass ejections.
