Based on new data from ESA's Gaia satellite, astronomers have provided more insights into properties of the nearby open cluster NGC 2682, revealing that its size is at least two times greater than previously believed. The ...
The bioactivity of most near-infrared II (NIRII) fluorophores are limited, thereby conflicting the achievement of strong fluorescence and high catalytic activities, due to a lack of free electrons in the method.
Using the LOw Frequency ARray (LOFAR) and the Very Large Array (VLA), astronomers have conducted radio observations of a galaxy cluster known as ClG 0217+70 and obtained important information regarding giant radio sources ...
Using the Canada–France–Hawaii Telescope (CFHT) and Keck Observatory, an international group of astronomers has performed a photometric and spectroscopic study of Laevens 3—a satellite globular cluster in the Milky ...
According to the most widely accepted cosmological models, the first galaxies began to form between 13 and 14 billion years ago. Over the course of the next billion years, the cosmic structures now observed first emerged. ...

(Phys.org)—A team of astronomers led by Andrés E. Piatti of the Astronomical Observatory of Córdoba in Argentina has recently observed an extra-tidal clumpy structure around the globular cluster NGC 288. The results of ...
This new NASA Hubble Space Telescope view shows the globular cluster NGC 2298, a sparkling collection of thousands of stars held together by their mutual gravitational attraction. Globular clusters are typically home to older ...
