An alligator’s brain weighs only 8 or 9 grams, and it has the size of a walnut, but that
A spectacular video (drones sacrificed while shooting it!) from the National Geographic: explorer Sam Cossman operated camera-mounted drones to capture high-definition images of the Marum (also spelled Maroum) crater in Ambrym, Vanuatu. Vanuatu is a Pacific island nation located in the South Pacific Ocean.Continue reading “Drones Sacrificed for this Spectacular Volcano Video”
In 2006, Planet Earth, the British television series produced by the BBC Natural History Unit “has changed our view of the world”. It was the first nature documentary series filmed in high definition. It took five years in the making and it was the most expensive nature documentary series ever commissioned by the BBC. Now, ten years later, in February 2016, the BBC announced a six-part sequel had been commissioned, titled Planet Earth II. In October 2016, BBC released the new series’ trailer.Continue reading “Planet Earth II Official Extended Trailer”
What if Mars still had liquid water on its surface and a thick atmosphere filled with clouds, like Earth? How would it look like? Software engineer Kevin Gill of JPL (NASA’s Jet Propulsion Laboratory) wondered this and prepared an image using data from NASA’s Mars Reconnaissance Orbiter (MRO)(see notes 1) and Mars Orbiter Laser Altimeter (MOLA)(see notes 2). The result is stunning!
Gill picked an arbitrary sea level and used GIMP (a free and open-source raster graphics editor used for image retouching and editing) to paint the features onto the satellite images using these measurements.Continue reading “How Mars would look if it still had water”
The Saffir-Simpson hurricane wind scale (SSHWS) is a 1 to 5 rating based on a hurricane’s sustained wind speed. The Weather Channel meteorologist Mark Elliot prepared a video titled “Why Hurricane Categories Make a Difference” and explained what each category means.Continue reading “Saffir-Simpson Hurricane Wind Scale Explained (Video)”
Proxima Centauri b, the Earth-like planet orbiting the red dwarf Proxima Centauri may have oceans, scientists say. The planet was discovered in August 2016 and caused excitement because it’s in the habitable zone of its star, and it’s rocky. And it’s in the Alpha Centauri, the closest star system to us!
Researches of France’s National Center for Scientific Research (CNRS) have calculated the size and surface properties of the planet and concluded it may be an “ocean planet” similar to Earth. There are possibilities, though, Proxima Centauri b may have continents and oceans like Earth, or its entire surface may be
Elon Musk, the founder, CEO, and Lead Designer of the private space travel company SpaceX announced that “they are planning to get humans to Mars in six years”. In order to achieve this goal, Musk revealed the Interplanetary Transport System, which aims to reach Mars with a human crew for the first time in history.Continue reading “SpaceX unveils the Interplanetary Transport System to colonize Mars”
Like crocodiles, snakes also suffer from a prevalence of “big fish” stories and over-exaggeration in the internet era. In fact, it is very difficult to measure how large actually a snake is, especially if it’s really big. So, how big are the largest snakes actually?Continue reading “Largest snakes of the world”
The largest insects on Earth – preparing such a list is not an easy task. Because, how can you identify the “large”? It is a relative term: if you mean the “bulkiest” by largest, for instance, this title may go to the Goliath beetle (Goliathus), which are among the largest insects on Earth, if measured in terms of size, bulk, and weight. They measure from 60-110 millimeters (2.4-4.3 in) for males and 50-80 millimeters (2.0-3.1 in) for females, as adults, and can reach weights of up to 80-100 grams (2.8-3.5 oz) in the larval stage, though the adults are only about half this weight.
Or maybe Actaeon beetle (Megasoma actaeon) claims the title, which is a rhinoceros beetle, a member of the Scarabaeidae family. They can be up to 7 centimeters (2.8 in) across, with a body length of up to 13.5 cm (5.4 in) long by 4 cm (1.6 in) thick.
