GENEVA – In what researchers are calling the “ultimate baby picture,” astrophysicists have confirmed that the universe isn’t just a vast, empty void—it has a definitive temperature. Data from space-based observatories have solidified our understanding of the Cosmic Microwave Background (CMB), the faint thermal glow left over from the dawn of time. While the night…
Introduction to Space Weathering on the Moon The Moon has no atmosphere, magnetic field or weather system to protect its surface. Because of this, it is constantly exposed to the Sun’s energy and particles. Over millions and billions of years, this exposure slowly changes the Moon’s surface. This long-term alteration caused mainly by the Sun…
Sun as the Source of LifeThe Sun provides the energy that makes life on Earth possible. Its light drives photosynthesis allowing plants to produce food and oxygen which supports almost all living organisms. Day and Night CycleThe rotation of Earth under the Sun creates day and night. This cycle controls sleeping, feeding and activity patterns…
