A meteorite is a mass of stone or metal which has reached the earth's surface from outer space. There are various names for a meteorite depending on where it is situated. While it is traveling in space, it is referred to as a "meteoroid". When it passes through the earth's atmosphere and produces a fiery streak in the sky, known as a "shooting star", it is called a "meteor".

Neil deGrasse Tyson has a talent for guiding readers through the mysteries of outer space with stunning clarity and almost childlike enthusiasm. This collection of his essays from Natural History magazine explores a myriad of cosmic topics. Tyson introduces us to the physics of black holes by explaining what would happen to our bodies if we fell into one; he also examines the needless friction between science and religion, and notes Earth's status as "an insignificantly small speck in the cosmos".

From the New York Times best-selling author of Seven Brief Lessons on Physics, The Order of Time, and Helgoland, a closer look at the mind-bending nature of the Universe. What are the elementary ingredients of the world? Do time and space exist? And what exactly is reality? Theoretical physicist Carlo Rovelli has spent his life exploring these questions. He tells us how our understanding of reality has changed over the centuries and how physicists think about the structure of the Universe today.

This playful, entertaining, and mind-bending introduction to modern physics briskly explains Einstein's general relativity, quantum mechanics, elementary particles, gravity, black holes, the complex architecture of the Universe, and the role humans play in this weird and wonderful world. Carlo Rovelli, a renowned theoretical physicist, is a delightfully poetic and philosophical scientific guide. He takes us to the frontiers of our knowledge: To the most minute reaches of the fabric of space, back to the origins of the cosmos, and into the workings of our minds.

Could “UFOs” and “aliens” simply be us, but from the future? This provocative new audiobook cautiously examines the premise that extraterrestrials may instead be our distant human descendants, using the anthropological tool of time travel to visit and study us in their own hominin evolutionary past.

Fifty years ago, a young astronomer named Frank Drake pointed a radio telescope at nearby stars in the hope of picking up a signal from an alien civilization. Thus began one of the boldest scientific projects in history, the Search for Extraterrestrial Intelligence (SETI). But after a half century of scanning the skies, astronomers have little to report but an eerie silence---eerie because many scientists are convinced that the universe is teeming with life.

In the sixteenth century, Nicolaus Copernicus dared to go against the establishment by proposing that Earth rotates around the Sun. Having demoted Earth from its unique position in the cosmos to one of mediocrity, Copernicus set in motion a revolution in scientific thought. This perspective has influenced our thinking for centuries. However, recent evidence challenges the Copernican Principle, hinting that we do in fact live in a special place, at a special time, as the product of a chain of unlikely events.

In 1974 a message was beamed towards the stars by the giant Arecibo telescope in Puerto Rico, a brief blast of radio waves designed to alert extraterrestrial civilizations to our existence. Of course, we don't know if such civilizations really exist. But for the past six decades a small cadre of researchers have been on a quest to find out, as part of SETI, the search for extraterrestrial intelligence.

An extraterrestrial colony, in some form, may already exist, just awaiting discovery. But the greatest impediment to such an important scientific discovery may not be technological, but political. No scientific endeavor can be launched without a budget, and matters of money are within the arena of politicians. Dr. Ben Bova explores some of the key players and the arguments waged in a debate of both scientific and cultural priorities.

"Imagine if a Martian showed up, all big ears and big nose like a child’s drawing, and he asked to be baptized. How would you react?" Pope Francis posed that question - without insisting on an answer! - to provoke deeper reflection about inclusiveness and diversity in the Church. But it's not the first time that question has been asked.

The galaxy, the multiverse, and the history of astronomy are explored in this engaging compilation of cosmological "tales" by multiple award-winning science writer Marcia Bartusiak. In 32 concise and engrossing essays, the author provides a deeper understanding of the nature of the universe and those who strive to uncover its mysteries. Bartusiak shares the back stories for many momentous astronomical discoveries, including the contributions of such pioneers as Beatrice Tinsley and her groundbreaking research in galactic evolution.

Winner of the Nobel Prize in Physics and author of the classic The First Three Minutes, Weinberg shares his views on some of the most fundamental and fascinating aspects of physics and the universe. But he does not seclude science behind disciplinary walls or shy away from politics, taking on what he sees as the folly of manned spaceflight, the harms of inequality, and the importance of public goods. His point of view is rationalist, realist, reductionist, and devoutly secularist.

Right now, you are orbiting a black hole. The Earth goes around the Sun, and the Sun goes around the centre of the Milky Way: a supermassive black hole—the strangest and most misunderstood phenomenon in the galaxy. In A Brief History of Black Holes, University of Oxford astrophysicist Dr Becky Smethurst charts the scientific breakthroughs that have uncovered the weird and wonderful world of black holes, from Hawking radiation to the iconic first photographs of a black hole in 2019.

Cosmos is one of the bestselling science books of all time. In clear-eyed prose, Sagan reveals a jewel-like blue world inhabited by a life form that is just beginning to discover its own identity and to venture into the vast ocean of space.

My beginner's book is your ticket to one of the coolest and most mysterious subjects out there. This isn't your average physics book. It's a portal to understanding the stuff that makes up... well, everything! Subatomic particles. Do not let their size fool you; they have a massive impact on the world around you—the fundamental part of how everything works and not as complex as you might fear.
