Nasa fulfilled an iconic mission by delivering an “abundance of sample” from asteroid Bennu to the Earth. The rocky samples were scrutted and tested by eminent scientists using ahead of the curve technologies incorporating chemical element analysis and infrared spectroscopy X-ray diffraction. Scientists deduced that the samples were rich in carbon and water-laden minerals and it was a bright discovery because there is a theory that carbon- rich (organic) and water-rich asteroids similar to Bennu may had been involved in delivering key components to the Earth system 4,5 billion years ago....

However, in the XX century, due to the destruction of the habitat, red wolves were on the verge of extinction. Then, by the end of the 70s of the XX century, red wolves in nature finally disappeared, and only individuals in zoos are left.🐾 This predator appeared as a result of crossing gray wolves with coyotes. Therefore, it has intermediate sizes between these two animals.From the gray wolf, red wolves different in smaller sizes...

New invention🚘
New inventions and technologies appear in our lives more often. Their use become usual for us. There are plenty of examples of how we use the usual things for us ,like a vacuum cleaner, car, computer, but some time ago people in the past cannot even think about this technologies.
