The Sloan Digital Sky Survey revolutionized the study of stars and galaxies, producing an incredible wealth of data. The man behind its development was astronomer Jim Gunn. […]
The National Geographic Society-Palomar Observatory Sky Survey began in 1949. It took nearly 10 years, but when it was finished, its data immediately became a great reference point for astronomers. […]
Constant changes happen in the space—from the motion of tiny asteroids to the brilliant flare of a supernova. To study them, we need surveys and detailed catalogs of the whole night sky. […]
The p-block elements make a kind of ‘staircase’ shape on the table. These elements are much more metallic than nonmetallic. And yet, they also have aspects of covalent, nonmetallic character. […]
Alpha particles are perfect when it comes to using them as a poison. They are easy to carry; lethal, both when ingested or inhaled; and conveniently decay away, leaving no trace behind. […]
The famous “Schrödinger’s cat” is more than a joke about the unknown. It’s a hypothetical way of understanding an idea in quantum mechanics known as superposition. This week on Wondrium, philosophy meets physics. […]
To test LIGO, fake signals were injected by some team members. Detectors kept receiving fake injections until the real thing was finally discovered. […]
Efforts and collaborations to observe gravitational waves lasted until 2015, when the first data were finally collected in September of that year. […]
Russell Hulse, Joseph Taylor, Rai Weiss, and Joseph Weber were the physicists who made efforts to explain and detect density waves in the fabric of spacetime. […]
In order to work accurately, the GPS system has to account for the changes in the curvature of spacetime because of gravity and its effects. And this application comes from Einstein’s theory of general relativity. […]
