Study Shows Quasars Could Extinguish Star Formation in Dusty Starburst Galaxies

Extinguished stars are abundantly present in some of the largest galaxies in the universe, but shortly after the universe was first created - almost 12 billion years ago - these huge galaxies were hotspots that produced billions of stars.

NASA/ESA Hubble Space Telescope Witnesses Gravitational Dance Between Two Galaxies

The gravitational dance between two galaxies in our local neighbourhood has led to intriguing visual features in both as witnessed in this new NASA/ESA Hubble Space Telescope image.

Penn Physicist Receives $1 Million Grant for Exploring a Class of Dark Energy Theories

A collaboration between University of Pennsylvania and University of California, Berkeley, that is exploring a class of dark energy theories, called chameleon theories, has been awarded $1 million from the W.M. Keck Foundation.

Ultracold Molecules Could Hold Quantum Information for Longer Time

Researchers have taken an important step toward the long-sought goal of a quantum computer, which in theory should be capable of vastly faster computations than conventional computers, for certain kinds of problems.

Scientists Calculate Distribution of Light Energy Contained Within the Milky Way

For the first time, a team of scientists have calculated the distribution of all light energy contained within the Milky Way, which will provide new insight into the make-up of our galaxy and how stars in spiral galaxies such as ours form.

Researchers Design New Technique to Generate Ultrafocused Electromagnetic Fields

Physicists working with researcher Oriol Romero-Isart devised a new simple scheme to theoretically generate arbitrarily short and focused electromagnetic fields. This new tool could be used for precise sensing and in microscopy.

ESO's VLT Survey Telescope Captures Spectacular Image of Orion Nebula Cluster

Using new observations from ESO’s VLT Survey Telescope, astronomers have discovered three different populations of young stars within the Orion Nebula Cluster. This unexpected discovery adds very valuable new insights for the understanding of how such clusters form.

New Way to Measure Robustness of Quantum Coherence of a Superimposed State

One of the main principles of quantum mechanics is the superposition of states. Systems are simultaneously in different states, i.e. "alive and dead" at the same time such as Schrödinger's cat, until someone measures them and the system opts for one of the possibilities.

New Numerical Simulations Help Scientists Reveal Secret of Magnetic Cycles in Stars

Using new numerical simulations and observations, scientists may now be able to explain why the Sun's magnetic field reverses every eleven years.

ASU astronomers Use Dark Energy Camera to Find Young Galaxies that Appeared After the Big Bang

ASU astronomers Sangeeta Malhotra and James Rhoads, working with international teams in Chile and China, have discovered 23 young galaxies, seen as they were 800 million years after the Big Bang. The results from this sample have been recently published in the Astrophysical Journal.
