What processes are involved in the formation of individual stars and stellar clusters in our own galaxy and other galaxies?
Like something from a video game, these simulations zoom through the entire evolution of young star clusters.
This simulation captures a mix of radiation, magnetic fields, gravity and other physical phenomena. It was produced with UC Berkeley’s code and run on the Pleiades supercomputer at the NASA Advanced Supercomputing facility at NASA’s Ames Research Center.

How do black holes work? What are black holes? Do they really exist? How can we find them?
These strange phenomenons have captured our imagination ever since they were predicted by Einstein's Theory of General Relativity in 1915 and today I hope to shed light on some of the dark mysteries surrounding black holes;
A star is essentially a huge, amazing fusion reactor. Because stars are so massive and made out of gas, there is an intense gravitational field that is always trying to collapse the star. The fusion reactions happening in the core are like a giant fusion bomb that is trying to explode the star. The balance between the gravitational forces and the explosive forces is what defines the …

"Abstract: We address the performance of an interferometric setup in which a squeezed single photon interferes at a beam splitter with a coherent state. Our analysis in based on both the quantum Fisher information and the sensitivity when a Mach-Zehnder setup is considered and the difference photocurrent is detected at the output. We compare our results with those obtained feeding the interferometer with a squeezed vacuum (with the same squeezing parameter of the squeezed single photon) and a coherent state in order to have the same total number of photons circulating in the interferometer. We find …
People often brag about Large Hadron Collider as having one of the most sophisticated Technology in the world. True, but even if you are living in France, it’s still inaccessible! I believe that accessibility is the true trait of technology.
Look around the place that you are sitting in. Do you see a Ball Point pen lying around in the vicinity? Chances are that it is, are really high.
Today, we will unravel the modest physics that governs it.
Behold the ball in a ball point pen!
To write you glide your pen onto the paper right? So what you are doing is rolling the ball that is present on the pen’s tip.
The ink flows continuously under the influence of gravity from the ink reservoir to the …
