World’s Largest Living Cat: Hercules, the liger (video)

Ligers are the largest cats on Earth. A liger can be more than 900 pounds (~408 kg) in weight and 12 feet (~3.65 m) long, weighing almost 100 times more than house cats and almost twice as much as either Panthera tigris (tiger) or Panthera leo (lion).

The liger, the largest of all known extant felines, is a hybrid cross between a male lion and a female tiger.

A Japanese Giant Hornet cooked by Honey Bees (video)

In the insects’ world, the Japanese Giant Hornet (Vespa mandarinia japonica) is a real beast. It is one of the subspecies of the Asian Giant Hornet (Vespa mandarinia), which is the world’s largest hornet. As its name suggests, it is endemic to the Japanese islands, where it prefers rural areas where it can find trees to nest in.

A single Japanese giant hornet can kill up to forty European honeybees a minute. So, a few of them can decimate an entire colony containing 30,000 bees. Compared to honeybees, it is a really giant: adults can be more than 4.5 centimeters (1.8 in) long, with a wingspan greater than 6 centimeters (2.4 in). It also has scissor-like teeth which can wreak havoc on its prey.

The first earthrise ever seen directly by humans

On December 24, 1968, the crew of Apollo 8, the second human spaceflight mission in the US Apollo space program, were the first humans to witness Earthrise. The “Earthrise” is photographed by astronauts on board Apollo 8. It is one of the most famous photos ever taken and became the symbol of one the greatest explorations in history: human’s first journey to another world, and when the crewmembers looked back, they saw their home planet.

NASA needs your help to identify cities in the night images

Since the “space age” has started in the early 1960s, astronauts have taken more than 1.8 million photographs of the Earth from orbit, and about one-third of them (approximately 600,000) have been taken at night. But they don’t always know what they are looking at. You can help, announced NASA.

Krakatoa, from space

On August 26-27, 1883, a small island in the Indian Ocean obliterated itself in one the most notorious volcanic eruptions in history. Krakatau (often spelled Krakatoa) erupted with such violence that two-thirds of the island, about 23 square kilometers, sank into the Sunda Strait. The explosions heard in the 1883 eruption remain the loudest noise on human record. The sound was heard across the Indian Ocean, as far away as Rodriguez Island, 4,653 kilometers (2,891 miles) to the west, and Australia, 3,450 kilometers (2,144 miles) to the east. The massive eruption also generated a series of tsunamis, which produced waves as high as 30 meters (98 feet) tall.

Will We Ever Visit Other Stars?

The Earth is our one and only home. As Carl Sagan said (Pale Blue Dot: A Vision of the Human Future in Space), “On Earth, everyone you love, everyone you know, everyone you ever heard of, every human being who ever was, lived out their lives. The aggregate of our joy and suffering, thousands of confident religions, ideologies, and economic doctrines, every hunter and forager, every hero and coward, every creator and destroyer of civilization, every king and peasant, every young couple in love, every mother and father, hopeful child, inventor and explorer, every teacher of morals, every corrupt politician, every “superstar,” every “supreme leader,” every saint and sinner in the history of our species lived there – on a mote of dust suspended in a sunbeam.”.

But will we ever leave our home and visit other stars in the future?

Our galaxy, “The Milky Way” is a barred spiral galaxy (a spiral galaxy with a central bar-shaped structure composed of stars) some 100,000-120,000 light-years in diameter, which contains 100-400 billion stars. It may contain at least as many planets as well. Our Sun (the Solar System) is located within the disk, about 27,000 light-years away from the Galactic Center, on the inner edge of one of the spiral-shaped concentrations of gas and dust called the Orion Arm.
