Off our solar system, there is quite a few super earths. This means an Earth-like rocky planet with up to 10 times more mass than our Earth. A study calculated what would happen if a super-Earth suddenly appeared in our solar system. Spoiler: The effects would be catastrophic. But the study was not done merely to describe a hypothetical doomsday scenario but to explore how our solar system and other star systems have formed. The idea for this study came about because, time and again, astronomers* wished that there was…

Today, March 8, is Women’s Day
March 8 is a special day for women. This is because it is International Women’s Day, often called “International Women’s Day.” The day symbolized equality between men and women and was created over 100 years ago.

The only thing is, in our latitudes, we take in enough vitamin A through food, so eating an overdose of carrots for the eyes is not necessary. Myth II: Reading in dim light is bad for your eyesReading in dim…

Eating less beef could help make global warming less drastic. Food is essential for human survival. At the same time, current food production is helping to drive climate change. Researchers calculate that by 2100, this sector could contribute nearly one degree of temperature increase. But they also have an idea about what could be done about it. A new study has produced disturbing results on the contribution of our food to climate change: By 2100, what ends up on people’s tables could contribute to heating the earth by up to…
Read MoreFull moon in March – it is getting closer to the earth now
With the Lenz Moon, the celestial body is approaching Earth again. But even more weighty are the position changes of Saturn and Pluto.

NASA’s Solar Dynamics Observatory (SDO) spacecraft recorded an extremely powerful solar flare on March 3. The burst of high-energy radiation is classified as X2.1, according to the U.S. space agency. X is the strongest class of solar flare. The higher the number, the stronger the eruption. The SDO, which NASA launched into Earth orbit about 11 years ago to study solar activity, filmed the event. The radiation released came from a solar region called AR 3234. Failure of shortwave radio signalsDuring an X-class eruption, there can be prolonged and widespread…

Read MoreEven a short walk a day prolongs life
Exercise lowers the risk of cardiovascular disease, cancer and other serious illnesses – according to a new study, you can benefit from this even with a short walk. For the study, an international team of researchers evaluated the results of 196 previously published studies in which more than 30 million people had participated. They calculated that about one in six premature deaths would have been prevented if each study participant exercised at least 150 minutes a week at moderate intensity, as the U.K.’s National Health Service (NHS) recommended. But even…
