Good vibrations. This false color image shows shock waves emanating from supersonic aircraft T-38 Talon from the USA. UU., Used to train fighter pilots. During the flights, at NASA's Armstrong Flight Research Center in Edwards, California, space agency personnel tested a system that captured high-quality images of shock waves. These rapid changes in air pressure cause people to hear "sonic explosions" on the ground. The image system data will help aeronautical engineers design a "silent" supersonic spacecraft.
Out on the asteroid. It's been a busy few months for the Japanese asteroid Hayabusa2. The probe, which is hung by a space rock called Ryugu, touched the body in late February and picked up some space earth that was ejected after the ship fired a bullet to the surface (in the image). On April 5, he made his most audacious maneuver so far: he threw an explosive to the surface to create a small crater that will expose some subsurface layers. Hayabusa2 will collect more material during a subsequent touch and eventually return the samples to Earth.
The dangers of the jungle. This X-ray image shows a three-month-old orangutan baby operated on a fractured arm in northern Sumatra, Indonesia, where oil palm plantations threaten tropical forests. The ape was operated at the rehabilitation center of the Orangutan Conservation Program of Sumatra in northern Sumatra. Brenda was rescued days after rescue workers found an adult orangutan named Hope in the area with 74 shots of air rifle in her body; The animal was blinded as a result. Conservationists warn that orangutans are likely to become the first great apes to become extinct in the wild.
Glbady eyes. The main taxidermist Christophe Gottini, at the French National Museum of Natural History in Paris, is working on the restoration of a giant squid for an exhibition in the ocean.
CSI: Charcoal. This image seems innocent enough, but it could help fight the growing fraud in trees. The micrograph shows a section of charcoal from a tropical tree of Fabaceae from Africa; was captured using a technique developed by Gerald Koch and Volker Haag at the Thünen Competence Center on the Origin of Wood in Hamburg, Germany. The method is part of a growing arsenal of tools that scientists are using to detect trees that have been felled and exported illegally. In 2017, Koch helped expose a scandal in which many Germans were burning charcoal that had been made from protected forest wood.
In thunder, lightning, or rain? This spectacular light show was captured in Santa Barbara, California, with a long exposure. The electric display came during winter storms that brought heavy rain, hail, thunder and lightning to southern California in early March.
Moon games. The Israeli lunar spacecraft Beresheet is on track to become the first private funding probe to land on the Moon. The spacecraft, which also has the backing of the Israeli space agency and was launched in February, has now made the leap from Earth orbit to lunar orbit and is scheduled to land on the Moon on April 11. The success of Beresheet and the renewed interest of the government in the rocky companion of the Earth seem to announce a new lunar space race.
