by using the distance from Earth to various galaxies and by calculating the ages of old, nearby stars.
It ways infinity because the universe is infinite
A quick estimate can be done by observing how fast galaxies move away from us (on average). If that is compared with the distance to the galaxies, then it looks as if all galaxies were closely together something like 13 or 14 billion years ago.
Space exploration has led to advancements in technology, such as satellite communication and weather forecasting systems. Discoveries from space missions have provided insights into the origins and evolution of the universe, planets, and celestial bodies. Space exploration enables scientists to conduct experiments in microgravity environments, leading to discoveries in various fields such as medicine and materials science.
A cirrus cloud can be described as wispy and feathery.
Scientists estimate the age of the universe and the Big Bang by studying the cosmic microwave background radiation, known as the afterglow of the Big Bang. By analyzing the temperature fluctuations in this radiation, researchers can determine the age of the universe to be approximately 13.8 billion years old.

Scientists describe matter in terms of its composition, properties, and behavior. They may categorize matter based on its physical state (solid, liquid, gas), chemical makeup (elements, compounds), or atomic and molecular structure. Scientists also analyze matter based on its physical and chemical properties such as mass, volume, density, and reactivity.
