Dazzling diamonds
Single stars are often overlooked in favor of their larger cosmic cousins -- but when they join forces, they create truly breathtaking scenes to rival even the most glowing of nebulae or swirling of galaxies. This NASA/ESA Hubble Space Telescope image features the star cluster Trumpler 14. One of the largest gatherings of hot, massive and bright stars in the Milky Way, this cluster houses some of the most luminous stars in our entire galaxy. (2016-01-21)

Cosmic fireworks
It's not every day you get to observe a gamma-ray binary system. In fact, it's a once-in-a-lifetime experience comparable to seeing Halley's Comet or a solar eclipse. Here's what a UD team saw. (2018-11-15)

How do plants protect themselves against sunburn?
To protect themselves against UV-B, which are highly harmful, plants have developed cellular tools to detect them and build biochemical defenses. A team of Swiss biologists discovered the existence of a UV-B receptor a few years ago. Today, these researchers demonstrate how these receptors, once activated by UV-B, associate with proteins that assist them to be assembled in the cell nucleus and to develop responses for survival and acclimation.

NASA's Webb Telescope to make a splash in search for interstellar water
Water is crucial for life, but how do you make water? Cooking up some H2O takes more than mixing hydrogen and oxygen. It requires the special conditions found deep within frigid molecular clouds, where dust shields against destructive ultraviolet light and aids chemical reactions. NASA's James Webb Space Telescope will peer into these cosmic reservoirs to gain new insights into the origin and evolution of water and other key building blocks for habitable planets. (2018-03-09)

Increasing temperatures in cooling systems
For the very first time, scientists from Friedrich-Alexander-Universität Erlangen-Nürnberg (FAU), the University of Leicester and the University of Vigo have proven that the kinetic energy from particles in granular gases such as dust clouds can rise temporarily even though energy is constantly being drawn out of the system. Their research adds further detail to Haff's law (devised 35 years ago), which states that the granular temperature in closed systems continually decreases. (2018-03-23)

Superradiance of an ensemble of nuclei excited by a free electron laser
A collaboration of scientists has succeeded in verifying a basic prediction of the quantum-mechanical behavior of resonant systems. In the study published in Nature Physics, they were able to carefully follow, one x-ray at a time, the decay of nuclei in a perfect crystal after excitation with a flash of x-rays. They observed a dramatic reduction of the time taken to emit the first x-ray as the number of x-rays increased. (2017-12-15)

Dawn of a galactic collision
A riot of color and light dances through this peculiarly shaped galaxy, NGC 5256. Its smoke-like plumes are flung out in all directions and the bright core illuminates the chaotic regions of gas and dust swirling through the galaxy's center. Its odd structure is due to the fact that this is not one galaxy, but two -- in the process of a galactic collision. (2017-12-14)

A cosmic gorilla effect could blind the detection of aliens
A well-known experiment with young people bouncing a ball showed that when an observer focuses on counting the passes, he does not detect if someone crosses the stage disguised as a gorilla. According to researchers at the University of Cádiz (Spain), something similar could be happening to us when we try to discover intelligent non-earthly signals, which perhaps manifest themselves in dimensions that escape our perception, such as the unknown dark matter and energy. (2018-04-10)
