Scientists at the University of Bath in the UK have found a way to bind together two photons of different colors, paving the way for important advancements in quantum-electrodynamics—the field of science that describes how light and matter interact. In time, the team’s findings are likely to impact developments in optical and quantum communication, and precision measurements of frequency, time and…

Astrophysicist’s 2004 theory confirmed: Why the Sun’s composition varies
About 17 years ago, J. Martin Laming, an astrophysicist at the U.S. Naval Research Laboratory, theorized why the chemical composition of the Sun’s tenuous outermost layer differs from that lower down. His theory has recently been validated by combined observations of the Sun’s magnetic waves from the Earth and from space.

Three elder sisters of the Sun with planets
An international team led by Prof. Dr. habil. Andrzej Niedzielski, an astronomer from the Nicolaus Copernicus University in Torun (Poland), has discovered yet another three extrasolar planets. These planets revolve around the stars that can be called elder sisters of our Sun. Source: https://phys.org/news/2021-03-elder-sisters-sun-planets.html…
Extinct atom reveals the long-kept secrets of the solar system
Using the extinct niobium-92 atom, ETH researchers have been able to date events in the early solar system with greater precision than before. The study concludes that supernova explosions must have taken place in the birth environment of our sun. Source: https://phys.org/news/2021-03-extinct-atom-reveals-long-kept-secrets.html…
Astronomers identify faint radio-jets in the galaxy cluster CLJ1449+0856
Using ground-based facilities and space telescopes, an international team of astronomers has conducted multiwavelength observations of a galaxy cluster known as CLJ1449+0856. The observational campaign detected multiple faint radio-jets, what could shed more light on the nature of this cluster. The finding is reported in a paper published February 23 on the arXiv pre-print server. Source: https://phys.org/news/2021-03-astronomers-faint-radio-jets-galaxy-cluster.html…
