Comets: where do they come from?

Posted on April 7, 2020 by maverickbennett

A comet is made of a nucleus (inner core), coma (cloudy envelope around the nucleus), and then a tail. Where exactly do these beautiful, fast-moving cosmic snowballs come from?

Through this, scientists believe that comets come fromContinue reading “Comets: where do they come from?” Continue reading →

The US National Snow and Ice Data Center (NSIDC) based in Boulder, Colorado, has been taking images of our planet for 34 years, documenting climate changes and ice levels across the planet. Data from the past five years show ice levels to be lower than any previously document years. Changes in climate and ice levels […] Continue reading →
