The James Webb Space Telescope's journey from start to finish.

A black body is a theoretical or imaginary object that perfectly absorbs all incoming electromagnetic radiation, and also emits radiation, like heat and visible light, based on its temperature. A black body is considered theoretical...

Sun is obviously the hottest thing in our Solar System, but it is a mere candle when compared to several other stars and stellar phenomena, particularly supernova. A supernova is a transient event that marks the last evolutionary stage...

Rancidity refers to the complete or incomplete hydrolysis or oxidation of fats and oils when exposed to air, light, moisture, and bacterial activity; this generally occurs in food items, making them undesirable for consumption. In more...

The fake puddles of water that we see on the road on a sunny day is due to an optical phenomenon called a mirage, which is caused by the refraction (or bending) of light rays due to different temperatures of the air above the road. On a...

Stealth is a critical component of modern warfare, allowing militaries to hide their most valuable assets from the enemy. Discover how advanced engineering, innovative materials, and ingenious design techniques enable nations to hide...

An igloo is made of compressed snow. Compact hardened snow is a great insulator of heat because snow is nothing but semi-frozen water with roughly 95% trapped air. The air molecules trapped between the tiny ice crystals create air...

The working of an electric iron is very simple – it draws electricity from the mains and heats a coil inside. This heat is then transferred to the bottom plate, which is pressed against the clothing to remove wrinkles. It is the...

The moment you think about astronauts, what comes to your mind would probably be a picture of an astronaut in a white spacesuit experiencing weightlessness in the vast expanse of space. Or perhaps you don't imagine a white astronaut. You...

Gasoline (petrol) and diesel are extracted from the same raw material crude oiland pass through various levels of refinement. Yet, they have different thermal characteristics, making them suitable for very different purposes. For...

Measuring actual temperature consists of recording the air temperature from a thermometer that has been kept inside a Stevenson screen or by using any other appropriate instrument. “Feels like temperature,†on the other hand, is a...

Heat death of the universe, also called The Big Chill or Big Freeze, will happen when the entropy of the universe will be so high that everything and everyone that lives in it will perish. This will happen because an organism living in...

Yes. Microwaves and radio waves are physically the same, i.e. both are forms of electromagnetic radiation. Some microwave rays can leak out and interfere with WiFi signals. We are basically constantly surrounded by electromagnetic...

One of the longest running arguments among sword enthusiasts revolves around the two dominant shapes of swords: curved and straight. Traditionally, straight swords have been used by Western European cultures, while curved swords are...

The term climate change is used to denote the long-term changes in the weather patterns in a given region. Another term often interchanged with climate change is global warming. Global warming is formally defined as a rise in Earth's...

Cellular respiration is the process through which the cell generates energy, in the form of ATP, using food and oxygen. The is a multistep biochemical process where food, primarily the carbohydrate glucose, is broken down to produce...

A black hole is a celestial body or simply a place in space where the gravitational pull is so high that nothing, not even light can escape it. This is why it's completely black, and hence it's called a black hole. A black hole's...

While Neptune, the most distant planet in our Solar System, is 4.5 billion kilometers away from the Sun, Uranus, the second-farthest planet, is just 2.88 billion kilometers away. Uranus is more than a billion kilometers away from...

Space is filled with countless stars, all of which radiate enormous amounts of heat. These stars are tens of thousands of times bigger than our own sun. Still, space is considered to be cold. Why is that? If there are so many hot burning...

Water is formed as a result of the combustion of hydrogen. In simple words, water is what you get when you burn hydrogen. So, water doesn’t burn because, in a way, it has already burned. You get ashes when you burn paper; but when you’re...

Water evaporates at room temperature because the molecules at the top of the liquid have less intermolecular attraction than those within the bulk. When the top layer is exposed to sunlight, some molecules gain enough kinetic energy to...

If we had twice the amount of oxygen, we have now, several significant changes would occur. Animals would grow larger as the increased oxygen supply would support their growth. Neutrophils, specialized white blood cells, would exhibit an...

Explore how researchers Ingo Sonder and Andrew Harp simulate volcanic eruptions to study magma-water interactions.

Learn about sustainable milk pasteurization practices directly from a dairyman. Discover how different pasteurization temperatures affect milk's safety, nutritional content, and shelf life.
