Gator Uses a Bait Stick to Catch Egrets (Video)

An alligator’s brain weighs only 8 or 9 grams, and it has the size of a walnut, but that doesn’t mean they are stupid. In fact, they’re much smarter than you’d think. In Everglades National Park in the United States, a 400-pound (181 kg) gator displays a clever way and uses a bait branch stick to catch egrets during the breeding season.

Drones Sacrificed for this Spectacular Volcano Video

A spectacular video (drones sacrificed while shooting it!) from National Geographic: explorer Sam Cossman operated camera-mounted drones to capture high-definition images of the Marum crater (also spelled Maroum) in Ambrym, Vanuatu. Vanuatu is a Pacific island nation located in the South Pacific Ocean.

Planet Earth II Official Extended Trailer

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. The making took five years 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 trailer of Planet Earth II.

This is how Mars would look if it still had water

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.

Saffir-Simpson Hurricane Wind Scale Explained [Wind Speed and Categories]

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.

SpaceX unveils the Interplanetary Transport System to colonize Mars

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.

The scale of the Solar System and the first flybys of planets

Previously I posted two articles titled “If The Moon Were Only 1 Pixel – A Tediously Accurate Map Of The Solar System“, and “A Scale Model of Solar System Drawn in the Desert and the Result is Stunning“. In these posts, science enthusiasts have shown the scale of the solar system realistically. Since the human brain cannot deal with really large numbers, these articles provide an amazing way to understand how big actually our Solar System is.

Now, I decided to put the Solar System into scale as an infographic. You can see the scale of the Solar System below, the planets’ distances from the Sun, and the first flybys over them. Plus some statistics about the planets and our home planet, the Earth. Planet sizes are not scaled since they’d be too small to be seen at this scale.

The fastest land animals

What are the fastest land animals? Like all the “biggest”, “fastest”, “largest”, etc. animals lists on the Internet, there is a tendency to overestimate also their top speeds. Even the speed of the world’s fastest land animal, the cheetah’s top speed is usually highly overestimated. In fact, measuring an animal’s speed is a very hard task, and very few of them were properly authenticated. Some of them are really fast, that’s true, but what is the exact number? This information is usually not measured correctly.

Okavango Delta, Botswana

The Okavango Delta is a unique pulsing wetland where the 1,600 km (990 mi) long Okavango River reaches a tectonic trough in the middle of the Kalahari Desert in northern Botswana. Each year approximately 11 cubic kilometers of water spread over the 6,000-37,500 km2 area. It is on the UNESCO World Heritage List as well as one of the Seven Natural Wonders of Africa (see notes 1).

Slope Point, New Zealand

“Slope Point” is the southernmost point of New Zealand’s South Island. It lies 4803 km (2984 mi) from the South Pole and 5140 km (3194 mi) from the equator. It offers spectacular views of the surrounding ocean and coastline.

The place is regularly exposed to extreme weather conditions including heavy winds. The fierce and cold Antarctic winds can uninterruptedly travel over the Southern Ocean for 3,200 km (2,000 miles) and turn trees into strange but somehow beautiful statues.
