Plastics can be divided into various classes according to the chemical process used during their creation and their physical properties, including their colour, clarity and flexibility. Naphtha is decomposed thermally in a steam cracker to produce light hydrocarbons known as major intermediaries such as olefins and aromatics that will then be fed into a factory […]

The Moon is currently passing through Earth’s shadow, known as its umbra. While direct sunlight may be blocked out by this phenomenon, our atmosphere scatters red light that produces an amber-hued hue on its surface that gives off a coppery-red tinge to give a coppery-red radiance for our nearest neighboring body of water. This will

Astronomers have known since the 1980s that Saturn’s iconic rings have been diminishing rapidly since they appeared over 400 million years ago. Scientists estimate that at their current rate of decline, one swimming pool worth of water could fall onto Saturn every 30 seconds – rendering its iconic rings nearly extinct within 300 million years!

Spacecraft are vehicles designed to transport people or cargo into space using rocket propulsion. Their primary use is leaving Earth’s gravity for other planets within our Solar System; those aboard such spacecraft are known as astronauts or cosmonauts. Orbital spacecraft resemble capsules or spaceplanes in shape and function. Reusable or expendable versions exist. Each requires

Space can be an unpredictable place; we’re continually losing pieces of vehicles that exploded on-orbit or experienced violent separation during orbit. Probably the best-known example was when Challenger disintegrated shortly after launch in 1986, killing its crew due to an O-ring failure and rubber seal separation issues on its booster rockets. Debris Researchers still are
