How do scientists classify stars?Characteristic Classification:Billions of stars light up the night sky; they twinkle and shine. While, from Earth, they look quite similar, stars each have specific characteristics, some of which are used by scientists to classify them....
Scientists may also classify plants on the basis of seeds. Some plants, for example, pinyon pines that grow at some of the higher desert elevations produce uncovered seeds that develop within the plant’s cones. Other plants such as desert grasses and some flowering plants produce seeds each w...

Most scientists take public opinion into account. Social scientists measure how the general public feels about various social concerns, services, political candidates, groups, and personalities. Scientific researchers may serve various roles such as market research specialist, research scientist, reporter an...
Since we're interested in the intensity and destructive power of storms, we also need to know how scientists classify them. The Enhanced Fujita (EF) Scale measures tornado intensity on a 0-5 scale by estimating wind speeds based on damage. Interestingly, this means very powerful tornadoes can...
Developing AI isn't like building an artificial heart — scientists don't have a simple, concrete model to work from. We do know that the brain contains billions and billions of neurons, and that we think and learn by establishing electrical connections between different neurons. But we don'...
NASA scientists continue to analyze the data from LDEF to learn about orbital debris populations and distributions.What's Inside a Typical Satellite? Satellites come in a variety of shapes and sizes and perform many different functions, but they all have several things in common. All of them ...
For centuries, biological scientists have worked to classify organisms in a way that would help clarify relationships among species through time and across different and constantly changing environments. In trying to delineate the order of the community of living things on earth, they have faced a ...
