But it is not 2.7 K everywhere you look. It has tiny temperature fluctuations which are super useful to us. Those temperature variations can tell us about the movement of objects and the densities of gasses in the universe. The CMB appears as a faint background noise. The glow is nearly ...
For years, astronomers struggled to calculate the age of the universe. Estimates ranged from 10 to 20 billion years old, a frustratingly large spread. But that was before the launch of the Hubble Space Telescope, named after the astronomer whose discovery 70 years ago began the quest to learn...

FAQ: How Do We Calculate the Number of Atoms in the Universe? How many atoms are estimated to be in the observable universe? It is estimated that there are around 1080 atoms in the observable universe. This number is derived from calculations based on the estimated number of galaxies, stars...
But you can't just weigh something the size of a galaxy – you have to find its mass by other methods. One method is to measure the light intensity, or luminosity. The more luminous a galaxy, the more mass it possesses. Another approach is to calculate the rotation of a galaxy's ...
As a result of these criteria, many stand-alone graduate schools, including Rockefeller University in New York and the University of California San Francisco, were eligible to be ranked and were included in the ranking universe. The second step was to calculate the rankings using the 13 indicator...
How old is the universe? And in another effort to calculate the age of the planet, scientists turned to the rocks that cover its surface. However, becauseplate tectonicsconstantly changes and revamps the crust, the first rocks have long since been recycled, melted down and reformed into new ...
The declination of the Sun is the angle between the light rays from the Sun and the Earth's equator. Since the Earth is tilted on its axis and rotates every year, the angle of declination changes throughout the year. Every year the solar declination goes
We are getting close to answering the age-old questions, "Why are we here? Where did we come from?" Does the universe in fact have a beginning or an end? And, if so, what are they like? If we find the answer to that, it would be the ultimate triumph of human reason. ...
Cans, drums, and pipes are common cylinders. To find the surface area of one of these items, you'll need to know how to find the surface area of a cylinder. A cylinder is composed of three faces -- a circular top and bottom, and a rectangular side. You c
