Que. Does NASA hire physicists? Ans. Astronomers and engineers are usually employed by NASA, but fewer physicists. You would need a Ph.D. in astrophysics, along with several peer-reviewed publications in top journals, and strong letters of recommendation, if you want to work on the research ...
In many ways, this game of vocabulary was as much a part of the space race as anything else. Nikita Khrushchev, the Soviet premier at the time, knew the power of propaganda better than anyone, so he wanted a name that was both descriptive and inspirational. Some argue that cosmonaut, ...
First, we have to figure out how far Earth travels. Earth takes about 365 days to orbit the sun. The orbit is an ellipse, but to make the math simpler, let's say it's a circle. So, Earth's orbit is the circumference of a circle. Thedistance from Earth to the sun— called anas...
“We have the pleasure of answering three big questions in astrophysics: How does the universe work? How did we get here within that universe? And are we alone in that Universe?” said Domagal-Goldman. “Those are big enough questions where we can’t answer them with one instrument. We ...
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 swirls around them and compresses, reaching...
How does a jet engine generate electricity? How is a cyclotron engine different than an ion engine? How much energy does a particle accelerator make? What is quantum efficiency? How loud is a jet engine in decibels? What process creates the physical thrust in a combustion engine?
How much does a space shuttle launch cost? Is the Soyuz spacecraft reusable? How long is the space shuttle Endeavour? What is a space shuttle terminal? What was the first space shuttle to orbit Earth? What is the difference between astronomy and astrophysics?
How much money does a astronomer make? The median annual wage for astronomerswas $119,730 in May2020. The median wage is the wage at which half the workers in an occupation earned more than that amount and half earned less. The lowest 10 percent earned less than $62,410, and the highe...
but there's so much stuff between us … we're not going to see them," De Buizer said. In total, with a white dwarf forming every two years or so, plus a couple of supernovas happening every 100 years, that's a grand total of nearly 53 stars dying each century in the Milky ...
“Why does it feel this way? Why is this fabric more expensive than this fabric over here? Why does it take so long to manufacture, are there ways of shortening that time? Are there ways of increasing or decreasing the number of quantities we need to make, how does that impact pricing...
