Book Description
Like no other telescope ever invented, the NASA/ESA Hubble Space Telescope has given us magnificent high resolution views of the gigantic cosmic collisions between galaxies. Hubble's images are snapshots in time and catch the colliding galaxies in different stages of collision. Thanks to a new and amazing set of 60 Hubble images, for the first time these different stages can be put together to form a still-frame movielike montage showing the incredible processes taking place as galaxies collide and merge. The significance of these cosmic encounters reaches far beyond aesthetics. Galaxy mergers may, in fact, be some of the most important processes that shape our universe. Colliding galaxies very likely, hold some of the most important clues to our cosmic past and to our destiny. It now seems clear that the Milky Way is continuously undergoing merging events, some small scale, others on a gigantic scale. And the importance of this process in the lives of galaxies is much greater than what was previously thought.

Book Description
In 2018, Lisa Harvey-Smith was appointed as the inaugural Australian Women in STEM Ambassador by the Australian Federal Government. Why is the Milky Way blue? Why isn’t a black hole dark? How many stars can you see with your naked eye?* How much hotter are blue stars than red ones?** Humans are the only known astronomers in the universe. When we look up at the night sky, we are linked to our ancestors. Away from city lights, we can see what generations of people before us have wondered at and weaved stories around. But all that will change. The Andromeda Galaxy is rushing towards us at 400,000 kilometres an hour. When Galaxies Collide will guide you to look at the night sky afresh. It peers 5.86 billion years into the future to consider the fate of Earth and its inhabitants. Will the solution be to live in space without a planet to call home? Will one of the other 100 billion planets spawn life? Learn how to watch this space. * 9,000, but only half of that from any given point on Earth. ** 38,000 degrees vs 3,000.

Book Description
Tour the incredible scope of the cosmos as we know it with the editor in chief of Astronomy, featuring jaw-dropping illustrations and full-color photography from the magazine’s archives, much of it never before published. “The natural history of the galaxies is majestic and deserves its own David Attenborough. In David Eicher, it may have just found him.”—Richard Dawkins Journey to the edges of our galaxy and beyond with one of the most widely recognized astronomy experts as your guide. Delve into the history of stargazing and space observation, learn how black holes power galaxies, and understand the classification of the different galaxy types. This illuminating book—with artful illustrations and never-before-seen space photography—will open your mind to the wonders of the universe that await.

The Andromeda Galaxy

Author: Paul Hodge
Publisher: Springer Science & Business Media
ISBN: 9780792316541
Category : Science
Languages : en
Pages : 378

Book Description
The Andromeda Galaxy, or M31, is an attractive galaxy for astronomers. It is close to us, it is of about the size of our galaxy, it provides some intriguing observational puzzles because the galaxy is nearly edge-on, and many objects can be studied in detail, because they are still sufficiently bright. With the current developments in instrumentation with which increasingly detailed studies of the Andromeda Galaxy can be made, this book provides a solid foundation for the start of new observations. This book is a mine of information about M31. It can be used as a reference by insiders, and at the same time it provides easy access for newcomers to the field.

Galaxies

Publisher: John Wiley & Sons
ISBN: 1119817994

Languages : en
Pages : 288

Book Description
Galaxies are vast ensembles of stars, gas and dust, embedded in dark matter halos. They are the basic building blocks of the Universe, gathered in groups, clusters and super-clusters. They exist in many forms, either as spheroids or disks. Classifications, such as the Hubble sequence (based on mass concentration and gas fraction) and the colormagnitude diagram (which separates a blue cloud from a red sequence) help to understand their formation and evolution. Galaxies spend a large part of their lives in the blue cloud, forming stars as spiral or dwarf galaxies. Then, via a mechanism that is still unclear, they stop forming stars and quietly end in the red sequence, as spheroids. This transformation may be due to galaxy interactions, or because of the feedback of active nuclei, through the energy released by their central super-massive black holes. These mechanisms could explain the history of cosmic star formation, the rate of which was far greater in the first half of the UniverseÂs life. Galaxies delves into all of these surrounding subjects in six chapters written by dedicated, specialist astronomers and researchers in the field, from their numerical simulations to their evolutions.

Book Description
Have you ever wondered what dark matter is or why galaxies collide? Or why the Moon is gradually drifting away from Earth? Space is really, really big, as Douglas Adams once pointed out, and there is no better guide to it than Fred Watson, astronomer to the stars. Fred Watson has taken the many, many questions that have been asked by listeners of his popular, long-running radio shows, and answered them in this collection. Questions he answers include How can you identify the constellations? Does the Earth wobble? Could you dump nuclear waste into the Sun? What makes pl.

Wrinkles in Time

Author: George Smoot
Publisher: Harper Collins
ISBN: 0061344443
Category : Science
Languages : en
Pages : 354

Book Description
Astrophysicist George Smoot spent decades pursuing the origin of the cosmos, "the holy grail of science," a relentless hunt that led him from the rain forests of Brazil to the frozen wastes of Antarctica. In his search he struggled against time, the elements, and the forces of ignorance and bureaucratic insanity. Finally, after years of research, Smoot and his dedicated team of Berkeley researchers succeeded in proving the unprovable—uncovering, inarguably and for all time, the secrets of the creation of the universe. Wrinkles in Time describes this startling discovery that would usher in a new scientific age—and win Smoot the Nobel Prize in Physics.

Fundamentals of Galaxy Dynamics, Formation and Evolution

Author: Ignacio Ferreras
Publisher: UCL Press
ISBN: 1911307614
Category : Science
Languages : en
Pages : 200

Book Description
Galaxies, along with their underlying dark matter halos, constitute the building blocks of structure in the Universe. Of all fundamental forces, gravity is the dominant one that drives the evolution of structures from small density seeds at early times to the galaxies we see today. The interactions among myriads of stars, or dark matter particles, in a gravitating structure produce a system with fascinating connotations to thermodynamics, with some analogies and some fundamental differences. Ignacio Ferreras presents a concise introduction to extragalactic astrophysics, with emphasis on stellar dynamics, and the growth of density fluctuations in an expanding Universe. Additional chapters are devoted to smaller systems (stellar clusters) and larger ones (galaxy clusters). Fundamentals of Galaxy Dynamics, Formation and Evolution is written for advanced undergraduates and beginning postgraduate students, providing a useful tool to get up to speed in a starting research career. Some of the derivations for the most important results are presented in detail to enable students appreciate the beauty of maths as a tool to understand the workings of galaxies. Each chapter includes a set of problems to help the student advance with the material.
