Magnetoreception is a sense which allows an organism to detect the Earth's magnetic field. Animals with this sense include some arthropods, molluscs, and vertebrates (fish, amphibians, reptiles, birds, and mammals). The sense is mainly used for orientation and navigation, but it may help some animals to
The axis of an equatorial mount is parallel to Earth's surface when observing stars at Earth's equator – but perpendicular to it when observing from one of Earth's poles. Equatorial mounts were specifically developed for a spherical and rotating Earth. If Earth were flat, an equatorial mount would not make sense.
Earth observation (EO) is the gathering of information about the physical, chemical, and biological systems of the planet Earth. [1] It can be performed via remote-sensing technologies (Earth observation satellites) or through direct-contact sensors in ground-based or airborne platforms (such as weather stations and weather balloons, for example).
Sensitivity to the earth's electromagnetic fields, or to weather pressure, can be used to aid navigation. Some animals can predict earthquakes. Predators put these senses to lethal use: a shark homes in on the body electricity of its prey, vampire bats detect the infra-red radiation of blood, and a rattlesnake sees a 'heat picture' of its victim.
Asteroid 2024 YR4 has a 1.3% chance of impacting Earth in 2032, NASA reports. Astronomers all over the world are watching the asteroid, trying to narrow down its future path.
NASA Earth science satellite fleet as of September 2020, planned through 2023. Earth observation satellite missions developed by the ESA as of 2019. Earth observation satellites are Earth-orbiting spacecraft with sensors used to collect imagery and measurements of the surface of the earth. These satellites are used to monitor short-term weather ...
