Historical moment: the first electric aircraft is certified in Europe

If electric cars do not surprise anyone, electric planes are still the future. But now this future is one step closer to mass production: the European Union Aviation Safety Agency (EASA) has certified an electric airplane for the first time. It turned out to be a single-engine Velis Electro of the Slovenian company Pipistrel. Obtaining this certificate allows you to launch the aircraft in mass production.

The first mysterious “black neutron star” discovered in history

In the universe there are stars of different sizes and densities. The largest of them, under certain conditions, can turn into black holes. Less massive objects transform into supernovae, ultimately becoming neutron stars. Recently, a new class of cosmic bodies was discovered, previously considered impossible.

Residents of the Earth saw a “circular” solar eclipse

Yesterday, June 21, an annular solar eclipse occurred. It received an unusual name due to the fact that the Moon located at the farthest point from the earth did not completely close the Sun, “turning” it into a ring of fire. Pictures and videos made by eyewitnesses of a spectacular natural phenomenon have already appeared on the network.

Astronomers have recorded an unusual radiance in the orbit of Mars

If you look at the Earth’s horizon from space at a certain angle, you can see a clear green glow. This unusual phenomenon is caused by oxygen, which reacts with electrons entering the atmosphere with the solar wind. Astronomers have suggested that a similar glow should be present on other planets, but only recently it was discovered in the atmosphere of Mars.

Researchers have learned to print biosensors directly on internal organs

Some people urgently need constant monitoring of their internal organs. For this, there are various equipment that a person must carry on himself. However, this is not always convenient and can cause discomfort. An alternative may be biosensors directly on the internal organs. American researchers just introduced the appropriate technology of 3D printing.

New technology allows the creation of chameleon robots

Currently, there is a whole class of materials that can change their color. All of them have a complex structure and are expensive to manufacture. American scientists have created a film that is applied in the form of a spray and is able to change color. One of the areas of its application can be robots with the ability to adapt to the environment.
