Researchers from the Seti Institute would have found meteorites that pass close to our planet every 4,000 years or so. The new meteor shower study published in the journal Icarus claims that it is possible to detect the path of comets passing close to Earth's orbit.
Peter Jenniskens of the SETI Institute, said: "Our studies have presented us with a dangerous situation from comets that orbited close to Earth around 2000 BC. This creates situational awareness for potentially dangerous comets that were last orbit near Earth.
Earth until 2000 BC. Until recently, we only knew five long-term comets as the parent bodies of one of our meteor showers but we have now identified nine more, and possibly up to 15. In the future, with more observations, we could be capable of detecting weaker rains and plotting the orbit of mother comets on even longer orbits.
These are the shooting stars you see with the naked eye. By plotting their direction of approach, these maps show the sky and the universe around us in a very different light. It probably means that these comets have returned to the solar system many times in the past, while their orbits have gradually changed ne time."
Prince of Liechtenstein accused of killing bear Arthur
According to the Romanian environmental group Agent Green and the Austrian VGT, Prince Emanuel of Liechtenstein killed Arthur, the biggest bear in Romania. Associated Press, a Romanian news agency, said the prince received permission from the Romanian Environmental Agency to hunt down a female bear who had caused damage to farmers in the village of Ojdula.
However, according to ambient groups, the prince did not kill the female bear for which he received permission, but the famous bear Arthur, the oldest specimen in Romania. Gabriel Paun, president of the NGO Agent Green, said: "I wonder how the prince could have confused a female bear who enters to do damage in a village, with the largest male alive, who lived in the depths of the forest.
Prince did not come to solve the problem of the locals but to kill the bear and take home the biggest trophy to hang on the wall." The brown bear is a species protected by international laws: moreover, Romania banned trophy hunting in 2016.
There are several dangers that endanger the survival of the bear: the most important are obviously climate change and activity. Human. Romanian Environment Minister Ta'nczos Barna said an investigation was opened to determine the precise circumstances of the bear's killing.
Ann-Kathrin Freude, coordinator of the Austrian NGO VGT, added: "Trophy hunting must be banned without exception, otherwise the conflicts will escalate and the species will be endangered, as has already happened in much of Europe. And It is a shame for Austria that Prince Emanuel has abused an exemption to kill this beautiful bear."
