Crocodiles really produce tears. But, they do not cry in the same way that humans do. They do not produce tears to show emotions like sadness or happiness.

Crocodiles generally avoid confrontations with hippopotamuses because they are much larger and more aggressive than crocodiles. Additionally, hippopotamuses live in groups, which makes it difficult for crocodiles to hunt them. Crocodiles typically hunt smaller, easier prey such as fish, birds, and mammals.

On December 4, 1996, Mars Pathfinder, a robotic spacecraft that was designed primarily to demonstrate a low-cost way of delivering a set of science instruments and a free-ranging rover (Sojourner) to the Martian Surface was launched from Cape Canaveral on top of a Delta II rocket.

On December 2, 1971, Soviet Union’s Mars 3 robotic space probe performed the first soft Mars landing. But, just 110 seconds after the landing, and 20 seconds after the transmissions has begun, it failed and transmitted just a gray image with no details. Although having no scientific value, this was the first transmission ever from the surface of Mars.

Did you ever wonder how much water is on Earth? Yes, the oceans cover about 71 percent of the Earth’s surface. But, volume is a concept that is hard to grasp.

On November 20, 1998, the first element of the International Space Station, the Russian module Zarya (which means “Sunrise” in Russian) was launched into space on top of a Proton rocket. It was the first step towards more than two decades of international cooperation, scientific research, and discovery.

On November 9, 1971, NASA’s Mariner 9 spacecraft entered Mars orbit and became the first spacecraft to maintain an orbit around another planet than Earth. Mariner 9 beat Soviet Union’s Mars 2 by 13 days despite being launched 11 days later than its Soviet counterpart.
In about 11 months, the orbiter mapped 85% of the Martian surface and sent back more than 7,000 pictures, including images of Olympus Mons (the highest mountain in the Solar System), Valles Marineris, and two natural satellites of Mars, Phobos, and Deimos.

The Super blue blood moon is a rare celestial phenomenon. It is made up of three coinciding events. A supermoon is a full moon when our satellite is at its closest (hence it appears bigger in the sky). A blue moon refers to an “extra” full moon, whereas a year that usually has 12 full moons has 13 instead. The “blue moon” reference is applied to the third full moon in a season with four full moons.
In addition to these two phenomena, during a lunar eclipse, when the moon passes through Earth’s extended shadow, it looks reddish, and that is a “blood moon”. When all those three phenomena occur at the same time, it’s called a Super blue blood moon.

Hurricanes are inevitable every year, but it often seems like they’re becoming deadlier with each passing season. On average, the world sees nearly 50 of these storms per year. Not all of them are devastating, but the ones that are will make the news and let you know just how much damage they caused. Here are the top 6 deadliest hurricanes ever recorded.
Unfortunately, this trend of severe hurricanes will likely continue due to climate change unless action is taken.
