How the EARTH sounds from SPACE: REAL SOUND

Image
Space is a hollow surface, an emptiness in which no sound can propagate. So you might think that space is in absolute silence. Suppose you turn your ears into receivers of radio waves. In that case, the space around the Earth suddenly becomes a symphonic constant of strange and incredible sounds. Let's listen to the music of space! You don't have to climb too high above the Earth to already be in space. Only 160 km high, the sound is no longer audible because there are not enough particles to spread sound waves. Even here in space, you can find many other types of waves. The ones that interest us most today are the electromagnetic waves that do not require other particles because they propagate by themselves through photons . In fact, right now, you are enjoying electromagnetic radiation through the light when you watch this video.  Radiation ranges from gamma rays with extremely high frequencies to radio waves that ca

The meteor that "touched" Earth made Venus come to life

Recently, traces of phosphine gas have been found in the clouds of Venus, suggesting that it could support life. But a new study suggests that the compounds may have originated on Earth. Harvard researchers suspect that the biosignature gas arrived on Venus from meteorites that hit our planet's atmosphere and crashed on the distant planet. The study finds that at least 600,000 space rocks immersed in the Earth's atmosphere have collided with Venus in the last 3.7 billion years. The 2017 meteor crashed into the Earth's atmosphere at 35,000 miles per hour for a minute and a half before returning to space. Based on its trajectory as it skimmed the atmosphere, the team estimates that the rock had a diameter of about 12 inches and probably weighed at least 132 pounds. Although the abundance of Earth's life in the upper atmosphere is unknown, these planetary shepherds may have been able to transfer microbial life between the atmosph

World's first full-scale, commercially viable hydrogen-powered plane

Aircrafts powered by Hydrogen: the world's first "commercially available" hydrogen-powered long-haul aircraft takes off over Great Britain in a big step towards zero emissions flights. The six-seater Piper M-Class aircraft has completed a 20-minute flight from Cranfield Airport in Bedfordshire. The small airplane is powered by hydrogen fuel cells The company that built the aircraft, ZeroAvia , received £2.7 million from state resources in September 2019. ZeroAvia will attempt the next attempt to fly the six-seater hydrogen powered aircraft 250 miles from the Orkney Islands.  A commercially available full-size hydrogen-powered aircraft has completed a successful flight over the skies of Bedfordshire, a world premiere.  Behind the first flight is the British company ZeroAvia, which hopes that commercial aviation will be emission free by 2023.  The successful 20-minute flight included a cab, take-off, full circumnavigat

People who eat after this hour gain more weight

The time you eat your dinner can affect your chances of gaining weight and your daily calorie intake. Which side are you on the equation? Late-day calorie consumption is associated with metabolic syndrome and obesity. People who eat after this hour gain more weight. How dinner could affect your levels of body fat What time do you usually eat your dinner? If the answer is after 6 pm, you should keep reading (if you have dinner before 6 pm, you can also keep reading and even feel good about yourself).  New research says that people who consume the "heaviest" meal of their day in terms of calories after 6 pm are fatter. Also, the total daily caloric intake of people who eat after six in the afternoon tends to be higher. The researchers explained that the reason for this is that people who eat later tend to be very hungry and consume more

Research: positive effect of bilingualism on children's brains

Image
According to the scientists, communication skills in two or more languages have a positive effect on the gray and white matter of the brain. Bilingualism is vital for the developing brain of a child and improves cognitive functions in old age. How does bilingualism affect children's language development? It is known from previous research that bilingualism has a positive effect on brain structure and cognitive ability in adults . Now an international team of scientists has shown evidence that a similar effect is observed in the developing brain. The findings are published on the University of Reading website. The effect of bilingualism on the brain of children's The team analyzed brain scans of children and adolescents who spoke two or more languages ​​and compared them to children who spoke only one language. Bilinguals have shown benefits in gray and white matter volume compared to pe
