Science is the systematic study of the natural world, aiming to understand and explain the principles and laws that govern the universe. It is a branch of knowledge that encompasses a wide range of fields, including physics, chemistry, biology, geology, astronomy, and many others. Through the scientific method, scientists use observation, experimentation, and analysis to …
What is Plastic? Plastic is a synthetic or semi-synthetic material made from a wide range of organic polymers, including polyethylene, polypropylene, polyvinyl chloride (PVC), polystyrene, and many others. These polymers are derived from natural gas or crude oil through a chemical process, which involves the combination of monomers to form long chains of polymer molecules. …

The number of stars we can see in our night sky with the naked eye has reduced dramatically over the past decade because of an increase in artificial light, according to a newly-released report. The study, led by Dr Christopher Kyba from the German Research Centre for Geosciences in Potsdam and published in the …

Samples from the 162173 Ryugu asteroid collected by Japan’s Hayabusa2 spacecraft could help us understand the chemical composition of our solar system Discovered in 1999, Japanese scientists working on the Hayabusa2 spacecraft have inspected the Ryugu asteroid, known as 162173 Ryugu, which was approximately 900 metres in diameter. In this asteroid, Ancient grains of …

A captured star has experienced multiple close encounters with a supermassive black hole in a distant galaxy — and possibly even survived having material ripped away by immense gravitational tidal forces. The destruction of a star by the gravitational forces of a supermassive black hole is a violent affair known as a tidal disruption …
After a long journey of 30 years, NASA’s Geotail satellite’s Mission has ended. Here’s why. Back on July 24, 1992, NASA had launched the Geotail Satellite Mission to gather a dataset on the structure and dynamics of the magnetosphere, Earth’s protective magnetic bubble. However, it is interesting to note that the satellite was originally …

The electric charge of dust particles is highly contributive in assessing plasma in laboratory experiments, in ionosphere layer, and in its interplanetary state. It is assumed that the dust particles are initially charge free, while electrons and ions eventually collide with the dust surface and have a high chance of sticking to them, thus …
