The most impressive scientific photos of 2015

2015 marks many memorable scientific events, recorded through impressive photos on topics such as physics, astronomy, animal world and natural phenomena.

According to Nature, the photo captures the fierce battle between two Komodo lizards during the mating season to compete for partners in Indonesia.This is the world's largest lizard species.Adults have an average body length of 2-3 meters and weigh about 70 kg.(Photo: Andrey Gudkov / Wildlife Photographer of the Year 2015.)

Shock waves created by T-385C supersonic jet were captured by another aircraft in the Mojave desert sky, California, USA.Researchers at the US Aerospace Agency (NASA) are exploiting a photography technique called "schlieren image", developed by German physicist August Toepler in 1864. The purpose of the study is to observe changes in the index of air refraction or the speed of light in a given environment.Shock waves exhibit a change in the air refractive index so it is easily identifiable in schlieren images.(Photo: NASA.)

The Planck satellite of the European Space Agency (ESA) captures a stunning image of the Large Magellanic Cloud (black, middle) and the Small Magellanic Cloud (bottom left) - two galaxies near our galaxy .The image recorded in the process of satellite Planck surveyed the sky to study cosmic microwave background radiation (electromagnetic radiation generated from the early period of the universe after the Big Bang big bang).(Photo: ESA / Planck Collaboration.)

The head of the berry weevil (scientific name Anthonomus grandis) is only a few millimeters across and magnified with a scanning electron microscope.(Photo: Daniel Kariko / Wellcome Images).

Free-electron laser (X-ray laser free) technology now opens a new era of structural analysis.In the picture, scientists use free electron-beam X-rays to image 3D structures of giant and complex viruses Acanthamoeba polyphaga mimivirus (APMV), with a diameter of up to 400 nm.APMV was discovered in 1992 in a waterfall in Bradford, England.(Photo: Tomas Ekeberg / Uppsala Univ./Am. Phys. Soc).

The Nebula ESO 378-1, also known as Southern Owl Nebula, is an ionized gas sphere as wide as 4 light-years away in the constellation Hydra, obtained by the Great Telescope at ESO, Chile's Southern Observatory, Chile. record.The glow of the nebula is a remnant from the ultraviolet radiation emitted by the dead star like a giant bubble floating in the darkness of the universe.(Photo: ESO).

In July 2015, the first images of Pluto were sent back to Earth by New Horizons spacecraft, including high-resolution images showing the shadow of Pluto inside the ring. book in the form of reflections from the Sun.In the solar system, Pluto is the most distant planet before being classified as a dwarf planet in 2006. After a 9-year journey, which exceeded 4.8 billion km, New Horizons became a spacecraft. first approaching Pluto, providing a close-up opportunity for scientists to observe because the planet is too far away and cannot be observed with telescopes, even in space.(Photo: NASA.)

Lightning is formed by the discharge inside a cloud, either between the cloud and the Earth's surface.To study this phenomenon, scientists at the University of Florida, USA, use a special device called a "lightning machine" to activate outdoor artificial lightning, and record sound waves. when lightning works.(Photo: Univ. Florida Lightning Research Group).

Detailed 3D map reveals the location of bacteria and chemicals on human skin areas.To create this map, two healthy volunteers performed at the request of researchers at the University of California, USA, not to bathe for three days.After three days, 400 specimens across the skin were analyzed to study existing bacteria on the skin and help scientists better understand the interactions between skin cells, bacteria and chemistry. remnant.(Photo: Bouslimani et al. Proc. Natl Acad. Sci. USA).

The scene of vultures swarming down zebra carcasses in the Serengeti plains in Africa is recorded through a tiny camera attached to the carcass.Although this scene is a bit gruesome, the bird's daily scavenging habit plays an important role in keeping the ecosystem from contamination.(Photo: Charlie Hamilton James / Wildlife Photographer of the Year 2015).

In September 2015, NASA scientists announced saltwater is capable of flowing on the surface of Mars during the summer.High-resolution images sent back to Earth by the spacecraft Mars Reconnaissance Orbiter show traces of leaked salt stretching a few hundred meters (dark grooves in the image).They radiate from the edge of Garni Crater at the foot of Melas Chasm on Mars.These steep slopes appear during the warm summer months on the red planet, then disappear when the temperature drops.(Photo: NASA / JPL / University of Arizona).

On April 22, 2015, Calbuco volcano in southern Chile erupted huge columns of ash as high as 16 km.This volcanic eruption forces authorities to evacuate 1,500 residents urgently in Puerto Montt City and surrounding areas.(Photo: Alex Vidal Brecas / Corbis).

The photograph of the stretched bird (Ramphastos sulfuratus) trapped in a net trap was taken by photographer Todd Forsgren, showing that birds in general and tampons in particular are being slaughtered by humans.The picture is in an Ornithological Photographs published in 2015.
