Space agencies, governments, researchers and commentators have isolated a large number of direct and indirect benefits of space exploration programs including: New technologies that can be utilized in other industries and society (such as the development of communications satellites) Improved knowledge of space and the origin of the universe
Space exploration also gives scientists the ability to perform experiments in other settings and expand humanity's knowledge. [67] Another claim is that space exploration is a necessity to humankind and that staying on Earth will eventually lead to extinction. Some of the reasons are lack of natural resources, comets, nuclear war, and worldwide ...
Cosmology is a branch of astronomy that studies the universe as a whole. Astronomy is one of the oldest natural sciences. The early civilizations in recorded history made methodical observations of the night sky. These include the Egyptians, Babylonians, Greeks, Indians, Chinese, Maya, and many ancient indigenous peoples of the Americas.
The physical universe is defined as all of space and time [a] (collectively referred to as spacetime) and their contents.

There’s so much to learn about the universe. Here’s where to start.
Asteroid 2024 YR4 has a 2% chance of hitting Earth in 2032. Astronomers are tracking it to refine estimates of its size and orbit to see how much of a risk the space rock poses.
Observations of Solar System bodies with other types of electromagnetic radiation became possible with radio astronomy, infrared astronomy, ultraviolet astronomy, X-ray astronomy, and gamma-ray astronomy. Robotic space probes, the Apollo program landings of humans on the Moon, and space telescopes have vastly increased human knowledge about the ...
Space archaeology – the study of human artifacts in outer space; Forensic astronomy – the use of astronomy, the scientific study of celestial objects, to determine the appearance of the sky at specific times in the past. Techniques used in astronomical research: Theoretical astronomy – mathematical modelling of celestial entities and ...
