A career as a physicist is quite interesting as it involves the individual exploring and identifying the fundamental principles that govern matter's structure and behaviour, energy-matter interaction and energy generation and transfer. In both theoretical and practical areas, these principles can be use...
Even if you're lucky enough to have access to a ground-based telescope, whose clarity depends on atmospheric factors like clouds, you won't get the lucidity these stunning celestial objects deserve. In 1946, an astrophysicist named Dr. Lyman Spitzer Jr. proposed putting a telescope in space ...
An astrophysicist explains We live in a universe of causes and effects. All effects are preceded by a cause, and all causes lead to effects. The speed of light limits how quickly causes can lead to effects. Because it’s a maximum speed limit for any motion or interaction, in a given ...
we haveSagittarius A*, a beast weighing more than 4.5 million suns. Usually, these giant black holes are quiet and dormant, just sipping on whatever bits of gas or stars that wander too close. But occasionally, they feast on a much larger meal. When they do, that gas ...
Optical light is also somewhat affected by Earth's atmosphere, even though not as much as the infrared and submillimeter wavelengths. While infrared and submillimeter radiation gets mostly absorbed, optical rays get a little dispersed by the molecules in the atmosphere, which means that observed obje...
National Science Foundation astrophysicist Joe Pesce told Hill.TV that the launching of the new rover Perseverance to explore Mars is a necessary step to eventual human exploration. “Mars has a very thin atmosphere – it requires quite extensive technology just to come in and land,” he ...
Unfortunately for us, we're as much a part of the animal kingdom as any sparrow or sea turtle. So although we might not realize it, light pollution affects us just as surely as it does them. The Dark Side of Light Pollution: Human Effects Globe-shaped light fixtures send light in ...
Calories technically don't even exist. A calorie is just a unit of measurement used to describe the amount of heat produced when a nutrient is burned in a metal oven called a calorimeter. And your body is much, much different than a simple metal oven. The process of burning fat or turni...
Nuclear fusion occurs initially within the early 1920s after British astrophysicist Arthur Eddington suggested that stars draw their energy from the fusion of hydrogen and forms helium.Answer and Explanation: The process in which two or atomic nuclei combine and form one or more atomic nuclei and ...
screens. We no longer look to the sky to forecast the weather, predict the seasons or plant our gardens. Most of us cannot even see the Milky Way. But First Nations Elders of the world still maintain this knowledge, and there is much we can learn from them.我们的目光已经从天空转向了...
