Project Mercury: The History and Legacy of America’s First Human Spaceflight Program examines the origins behind the missions, the people and spacecraft involved, and the historic results. Along with pictures of important people, places, and events, you will learn about Mercury like never before. 

The early history of Earth covers such vast stretches of time that years, centuries, and even millennia become virtually meaningless. Instead, paleontologists and scientists who study geochronology divide time into periods and eras. The current view of science is that Earth is around 4.6 billion years old, and the first four billion years of its development are known as the Precambrian period.

Project Gemini is a neglected part of the US space program. Sandwiched between the excitement of Project Mercury and the sending of the first American astronauts to space and the euphoria of the Apollo Moon landings, Gemini was a step forward rather than a dramatic leap. However, this project achieved many important firsts, including the first spacewalk, the first rendezvous and docking between two spacecraft, the first flights of more than one week’s duration, and many more. 

Around eight o'clock a.m. on December 26, a massive earthquake registering 9.1-9.3 on the Richter Scale struck off of Sumatra, Indonesia, making it the third strongest earthquake ever recorded by seismographs. On top of that, the earthquake shook for nearly 10 minutes and generated incredibly strong tsunami waves. Thanks to the element of surprise, people in the region had virtually no warning of what was coming. The tsunami waves pulverized entire towns and swept away hundreds of thousands of people across Southeast Asia.

The oceans of the world have always had an air of mystery. About 71% of the Earth's surface is covered by water, and until the 20th century no one had plumbed its depths. Even today the bigger seas and oceans remain a largely unexplored frontier, with new species being discovered every year. Thus it comes as no surprise that countless legends have arisen of strange creatures lurking in the depths.

At one point or another, just about everyone has heard of the dodo bird, which is almost universally described as a cuddly, whimsical creature renowned for its alleged stupidity. This prehistoric avian had been known for hundreds of years, before it was made popular around the world in Lewis Carroll’s 1865 classic Alice's Adventures in Wonderland.

One of the most famous, and important, intellectuals to hail from Denmark is Niels Bohr, a world-famous physicist and one of the patriarchs of quantum theory. Given the vibrant, peaceful haven that is Denmark today, it’s somewhat ironic that Bohr played an instrumental role in the development of the atomic bomb. Even so, the truth and depth of the matter, much like the self-professed pacifist himself, is far more complex. 

It has long been a maxim that it is easy to forget when one is at war who the enemy really is, and that can certainly be said for the Ebola virus, which recently catapulted into headlines and instantly became the most feared disease in the world. In the case of the fight against Ebola, the enemy is not the person who has contracted the disease, nor is it the region where the virus has flourished. The enemy is a microscopic virus that, when seen under sufficient magnification, looks like a piece of loosely knotted rope.

The early history of Earth covers such vast stretches of time that years, centuries, and even millennia become virtually meaningless. Instead, paleontologists and scientists who study geochronology divide time into periods and eras. What humans commonly refer to as the “Ice Age” is actually a series of fluctuating climate events that have occurred throughout the planet’s history. These ongoing historical phenomena are difficult to conceptualize because of both the time frame involved and the natural process by which they cyclically unfold. 

Just trying to define a man who had the qualities of a mathematician, astronomer, philosopher, inventor, and astrologer can prove difficult. But all of that can be ascribed to Johannes Kepler, one of the giants of his era who ushered in the Scientific Revolution and is often considered the first modern scientist.

Discover the the life and accomplishments of Max Planck, theoretical physicist whose revolutionary discovery of energy quanta and formulation of fundamental quantum theory allowed for countless others to expand on the knowledge of atomic processes.

The Pleistocene spans a period from around 2.5 million years ago (mya) to just over 12,000 years ago, and it was an epoch of enormous change on Earth, mainly characterized by climate changes involving fluctuations between periods of extreme heat and long periods of glaciation. This period is commonly known as the Ice Age, despite the fact there were actually a number of separate periods of cold. The Pleistocene Era: The History of the Ice Age and the Dawn of Modern Humans looks at the development of the era, what life on Earth was like, and the origins of archaic humans. 

The early history of our planet covers such vast stretches of time that years, centuries, and even millennia become virtually meaningless. Instead paleontologists and scientists who study geochronology divide time into periods and eras. The current view of science is that planet Earth is around 4.6 billion years old. The first four billion years of its development are known as the Precambrian period. For the first billion years or so, there was no life in Earth. Then the first single-celled life-forms, early bacteria and algae, began to emerge.

Scientists have long attempted to understand Earth’s past, and in service to that effort, they have divided the world’s history into eons, eras, periods, epochs, and ages. For example, the current eon is called the Phanerozoic Eon, which means “visible life”. This is the eon in which multicellular life has evolved and thrived. Before this, life was microscopic (single cells).

Scientists have long attempted to understand Earth’s past, and in service to that effort, they have divided the world’s history into eons, eras, periods, epochs, and ages. The Triassic Period: The History and Legacy of the Geologic Era that Witnessed the Rise of Dinosaurs looks at the development of the era, the extinction events that preceded it, and how dinosaurs began to evolve in the Late Triassic. You will learn about the Triassic Period like never before.

Mankind's obsession with felines is an enigma in and of itself. Unlike dogs, famously known as man's most excitable, trustworthy, and loyal friend, cats are oftentimes indifferent, guarded, and yet finicky little furry creatures that only yearn for attention and affection when one is neck-deep in work or otherwise preoccupied. And still, people adore them all the same.

As the oft-repeated and invariably accurate pearl of wisdom goes, a dog truly is man's best friend. For a long time, people have almost universally loved dogs, and it seems to have been that way for at least tens of thousands of years. When affection is abundantly and consistently expressed, this pure, unspoken, wholesome love is one that is very much requited, and then some. This bond can be demonstrated by the mere existence of pet keepers who unironically refer to themselves as “dog parents,” not merely “dog owners”. 

While it would be impossible to name every individual who has contributed to the ever-advancing field of science, it almost goes without saying that one of the most important was Louis Pasteur, father of microbiology and modern immunology. Apart from propelling the field of vaccination to new heights, this visionary scientist would also revolutionize a significant part of the beverage industry, and highlight the importance of sterilization. These are only some of the extraordinary achievements on Louis' glaring résumé, one so well-rounded and extensive that it beggars belief.

On April 24, 1990, the Space Shuttle Discovery lifted off from Kennedy Space Center on the Space Shuttle Program’s 35th mission, but this was no ordinary mission. In its payload bay, Discovery was carrying the Hubble Space Telescope, with the objective of putting the telescope into orbit.
