Strongest acid – Fluoroantimonic acid
Strongest acid – Fluoroantimonic acid – Actually, it is a super acid that is a mixture of hydrofluoric acid (HF) and antimony pentafluoride (SbF5). It is a thousand trillion times stronger than concentrated sulfuric acid. Even short-term contact with the skin can result in serious injuries or death – just like inhaling its vapors. Fluoroantimonic acid is stored in special containers.
TRAPPIST-1e – Exoplanet from system TRAPPIST-1
TRAPPIST-1e – The stony exoplanet of the TRAPPIST-1 system, according to physical properties, is the “e” from the planetary system TRAPPIST is the most similar to Earth.
Size: 0,9 Earth
Mass: 0,8 Earth
Equivalent temperature: -22°C
It moves in the middle of the ecosystem of the entire collection, but there is the least water here. TRAPPIST-1e has a smaller size than Earth, but it has a larger mass. Possible inhabitants would have to be smaller in height and more important to cope with the pressure of local gravity. Red dwarfs, to which the TRAPPIST-1 star belongs, do not emit as much light and heat as the Sun. This means that the ecosphere, in which liquid water can sustain in proper conditions, is located in much closer orbits than in our solar system. A year on the planet TRAPPIST-1e lasts six ordinary earth days.
The planet probably also has a compact atmosphere where hydrogen is lacking. This type of atmosphere can also be found on the rocky planets of our solar system. Hydrogen is also a greenhouse gas, if it was a large amount in the local atmosphere, the surface of the planet would be uninhabitable.
Molecules from space – Primary gas created shortly after Big Bang
Molecules from space – Primary gas created shortly after Big Bang – Has been confirmed the
hypothesis about the origin of molecules from space. The researchers were able to discover
the so-called. Primary gas, which was created shortly after the Big Bang, it consists of hydrogen
and its heavier isotope deuterium. This finding confirms that in the Big Bang were created only the
lightest chemical elements, hydrogen and helium. Heavier elements appeared only after 100 Mln years.
Chernobyl Disaster – Accident in nuclear power plant
Chernobyl Disaster – Accident in nuclear power plant – In 26.04.1986 accident occurred
in the nuclear power plant in Chernobyl, Ukraine. The cause was an explosion of hydrogen
in a nuclear reactor. Contaminated surface was 125-146 thousands km² of Ukraine, Belarus,
Russia, and the radioactive cloud was moving over Europe. Because of contamination
were evacuated and resettled more than 350 thousands people.
Watches radioactive material
Watches radioactive material – Until the 60s of the twentieth century, commonly used in watches radioactive material – radium 226, so that their shields and guidance glowed in the dark. Today fluorescent paint which is coated dials comprises tritium. It is a radioactive isotope of hydrogen, but its small amounts are considered harmless to humans.
Martian methane – Detected in meteorites from Mars
Martian methane – Detected in meteorites from Mars – Canadian researchers from the University of Brock, in six meteorites from Mars have detected the presence of methane. The researchers also found traces of carbon dioxide, hydrogen, nitrogen, oxygen and argon. Methane was formed in meteorites probably under the influence of chemical reactions, so it is not of biological origin as methane on Earth. Scientists believe that the volcanic rocks of Mars there are large quantities of methane, which could be a source of energy for underground microbes. This confirms the theory that the Earth there are microbes that live thanks to methane. They live on the bottoms of the oceans in layers of basalt and do not need oxygen. Signals the presence of methane in the Martian atmosphere appeared more than 10 years ago, but so far have failed to unequivocally confirm.
