Bomb cyclone (NASA /NOAA GOES Project/Twitter), a rotating winter storm, ravaged the east coast of the United States in June 5438+ 10, and took some amazing satellite images, such as this one taken by GOES East satellite of the National Oceanic and Atmospheric Administration. This storm is also an opportunity for us to understand some phenomena described in cool words-bomb whirlwind and. . . . Wait, the explosion happened. When the air pressure in the weather system drops rapidly, resulting in a rapid increase in the intensity of the system or storm, a bomb cyclone will occur; The result may be hurricane-level winds and widespread snowfall. The process of creating an evil storm is called explosion.
Creepy Xuanqinghe Hello, nightmare! In June 5438+10, scientists discovered this rare shark, called Trigognathus kabeyai, while conducting a routine fish survey along the coast of Taiwan Province Province. Black sharks have sharp needle-like teeth; A dull, creepy look; A glowing abdomen and possibly an elongated chin. This species was not discovered until 1986. Even today, people know so little about these alien creatures that scientists are not sure whether they are endangered or difficult to find.
The black of the bird of paradise (BBC) is not much darker than the feathers of the male bird of paradise. This year, a new study revealed how these birds did it. The results show that the shape of black feathers of these rainforest birds is different from that of ordinary black feathers at the micro level. Feathers' unique nanostructure makes them particularly easy to scatter and reabsorb light, which in turn makes them not only black, but also black, so that they seem to absorb light.
Pelican Spider Assassin (Hannah Wood, Smithsonian) As reported by Life Science magazine in 1 month, this spider may be the strangest assassin you have ever seen. Assassin: At night, this spider is not weaving a web, but tracking the silk left by other spiders, slowing down the crawling speed of its six hind legs (usually upside down), while its two front legs pass by in the air and feel the existence of prey. Once it reaches another spider web, the assassin can wait for several hours, waiting for the best opportunity to attack, and use his beak pliers named Cherikray to pierce the unsuspecting spider. When the spider is not in the assassin mode, it will connect the spider's head and body with pliers, which is a long-necked appendage of the pelican type.
Tim Heard's picture of Australian stingless bee (carbon tetragonal bee) was taken by entomologist Tim Heard in June this year at 65438+ 10 and posted on Reddit. * * * isomorphic built this spiral nest, which looks delicious (or not). The spiral tower is called hatching comb, which connects hundreds of egg chambers together to form a ladder for developing larvae. The fully developed nest consists of 10-20 layers. Hurd of CSIRO told Live Science that each layer is a continuous spiral circle.
This year 1 month, divers discovered a new batch of rare Dai Mo hawksbill, which seems to be at the bottom of the sea. This fish is called thyme, which is extremely endangered. Previously, scientists only knew about 20 to 40 punk-looking swimmers living on the southeast coast of Tasmania. The new population lives nearby, but in order to protect the fish, the researchers remain silent about the exact location. This discovery basically makes scientists think that the number of red-handed fish left on the earth has doubled.
Tobias Friedrich/UPY 20 18 is the submarine "graveyard" of British World War I motorcycles, which is unforgettable and beautiful. This photo won photographer tobias Friedrich the top prize of "Underwater Photographer of the Year" this year. In this photo, the abandoned Norton 16H motorcycle lies on the deck of the British quartermaster ship sunk by German bombers in the Red Sea on June 6th, 2008. It seems that the same cycle is part of the lost goods on board, which has long attracted Friedrich. He painstakingly figured out how to capture the whole deck in one photo.
Little antelope (Joint Health Monitoring Team of Saiga antelope in Kazakhstan (Kazakhstan Biodiversity Conservation Association, Institute of Biosafety, Gvarderskiyrk, Royal Veterinary College of London, 2065438+May 2005), in just three weeks, 200,000 Saiga antelope endangered died. This is 62% of the newly declining Saiga people in the world. It was not until this year that scientists found the culprit: a bacterium that usually lives in the intestines of antelopes (without causing any problems), but the warm and humid weather triggered its overgrowth. This is how Pasteurella enters the blood of antelope and kills them. Here, a lovely newborn antelope lies in the arms of a scientist. Nervous system (Museum of Osteopathy Medicine) Have you ever thought that you would look like a nervous system? This is not surprising: as early as 1925, two medical students in Kirksville, Missouri-M.A. Schalck and L.P. Ramsdell-accepted the challenge of dissecting the entire human nervous system. Their works are still on display at the Museum of Orthopedic Medicine at A.T. Steele University in Missouri. This year, a photo of them went viral on Reddit.
Super Blue Blood Moon (VCG/Getty)1+1October 3 1 Early this morning, an eclipse of the super blue blood moon lit up the sky and dazzled people on earth, which has never happened in 152 years. This is the meaning of night sky events: super moon, when it is a full moon, the sphere is perigee, or the point closest to the earth in its orbit, and the moon passes through the shadow of the earth (eclipse). This is also the second full moon in January, which means it is called the blue moon. However, the moon is not blue, but red because our atmosphere filters the reflected light from the sun.
