A powerful X-ray telescope was launched yesterday

The Spektr-RG telescope was launched yesterday, July 13th, in Russia. It uses X-rays to map the entire sky with a lot of detail. Researchers say this will help them to understand the structure of the universe. The hope is Spektr-RG can provide fresh insights on the accelerating behaviour of cosmic expansion. And it should also recieve X-rays from the black holes that reside in our galaxy. But before it can begin working, it will take many weeks before it reaches its observing position which is 1.5 million km from earth.

Why this year has been so dangerous for Mount Everest's climbers: Everest has always been extremely dangerous, but this climbing season has had 11 deaths so far, that are not related to one event as it usually is, but to several factors. Mountaineers have suggested difficult weather conditions, a lack of experience and the growing commercialization of expeditions are contributing to the danger.   During the week beginning May 20, crowds of climbers became stuck in a queue (fila) to the summit (cima), above the mountain's highest camp at 8,000 meters. Most people can only spend a matter of minutes at the summit without extra oxygen supplies, and the area where mountaineers have been delayed is known to many as the "death zone." (It causes high altitutes sickness) Alan Arnette, who has climbed Everest four times, explained that Nepal issued a record number of permits to foreigners this year. Because each of them requires a Sherpa guide, there are about 800 pe...

Yesterday (7/05/19) one student was killed and eight were injured in a school shooting in Colorado, Usa. The police hasn't reveiled the identity of the shooters yet but it is believed that it was carried out by two two students; a boy and a girl. It took place in the middle school and witnesses declare that the victim, who was identified as 18 year-old Kendrick Castillo who was graduating in three more days, tackled the student in order to give the others time to escape but died in the attempt. This type of news make me really angry because american politicians knows that the real solution to this problem is implementing a tougher policy on control but like many of them are being payed or are related to weapon factories they prefer to implement inefective policies such as metal detectors or even allowing teachers to carry guns and is more than clearer that this is not working and I don't think is fair that kids have to study in that environment and continue to die because of n...

USA Huawei Ban

  Recently, with technological advances coming from every country, tension has risen to determine who will be the first country to developed a fully fleshed 5G communications system. A company from China called Huawei, has made several advances and was planning to give its services to a great part of Europe and other parts of the world. However, due to previous suspicions of spying from the Chinese goverment and a supposedly stealing of vital government information, the USA has decided to ban Huawei from doing business with any company from the United States of America without a previous approval from the goverment. In addition to this, the USA has urged its allies and economical partners to cut ties with Huawei, threatening to stop sharing confidential information with them. As a consequence, the Chinese company has been cut from using services such as Google, processors from Intel and Qualcomm, and software from Microsoft and other US companies, leading to a dip in sales and a b...
