According to some scientists, the world entered a completely new geological era called “Anthropocene”. And the reason is humans because we changed the world so much. Now, a very good and detailed article written by the American science writer Peter Brannen and published on The Atlantic argues that so-called Anthropocene is not a new era, […]
Now we’re living on a warm, hospitable planet. As Carl Sagan has said “That’s home. That’s us. On it everyone you love, everyone you know, everyone you ever heard of, every human being who ever was, lived out their lives.” We, humans, are the unquestionable rulers of our little oasis in a hostile universe. But […]
This amazing photo of the 2019 Solar Eclipse from the Moon’s orbit was taken on July 2, 2019, by the Chinese lunar satellite DSLWP-B (Longjiang-2).
Earth, our blue planet is a tiny oasis in the vast, cold, and dark space. It is the only planet we know of that can support life. The fossil record tells us that life on Earth has lasted at least 3.5 billion years (the Earth is about 4.54 billion years old), with the oldest physical […]
According to a new study published in the May 2, 2019 issue of Nature, 4.6 billion years ago, two neutron stars collided near the early Solar System (actually about 1000 light years from the gas cloud that eventually formed the Solar System). This violent collision has created heavy elements like silver, gold, platinum, cesium, and […]
Melodysheep published an amazing video titled “Timelapse of the future: a journey to the end of time”. This experience takes us on a journey to the end of time, trillions of trillions of years into the future, to discover what the fate of our planet, our sun, and our universe may ultimately be. If this […]
March 22, 2019, is World Water Day. Water is a basic human right. According to the United Nations, Water scarcity affects more than 40% of people (40% !) around the world, and this is projected to increase with the rise of global temperatures. Providing clean water and sanitation for all is a huge challenge.
As early as prehistoric times, humankind was fascinated by the night sky and all of its beauty. For centuries, philosophers and scholars would attribute magical properties to the bright stars and the Milky Way. In more recent times, we understand better what these mysterious objects are, and we can observe far more than our ancestors […]
On December 18, 2018, at around noon local time, a meteor about 10 meters (30 feet) long and weighing more than 1,500 tons, plunged into Earth’s atmosphere. It exploded over the Bering Sea and released energy equivalent to 173 kilotons of TNT – at least ten times more powerful than “Little Boy”, the atomic bomb […]
According to a new study published in the American Geophysical Union’s (AGU) Journal of Geophysical Research, the geocorona (the luminous part of the outermost region of the Earth’s atmosphere, the exosphere) reaches up to 630,000 kilometers (391,000 miles) away, or 50 times the diameter of our planet. For comparison, the average distance between Earth and […]
