In the largest and one of the most ambitious Hubble Space Telescope programs ever executed, a team of scientists and engineers collected information on almost 500 stars over a three-year period. This effort offers new insights ...
A study from the Instituto de Astrofísica de Canarias (IAC) which combines laboratory chemistry with astrophysics, has shown for the first time that grains of dust formed by carbon and hydrogen in a highly disordered state, ...
Accounts of supernovae—exploding stars—go back thousands of years, and while we know today these events create the building blocks of life itself, there are still unanswered questions about the conditions that cause a ...
Titan is the second-largest moon in the solar system and the only one with a dense atmosphere. At the top of this atmosphere, rich in nitrogen and methane, the sun's radiation produces a great diversity of organic molecules, ...
A new study published in Nature Astronomy describes the most luminous object ever observed by astronomers. It is a black hole with a mass of 17 billion Suns, swallowing a greater amount of mass than the sun every single day.
In the beginning, the universe was so hot and so dense that light could not travel far. Photons were emitted, scattered, and absorbed as quickly as the photons in the heart of the brightest stars. But in time the cosmos expanded ...
Water electrolysis is a promising approach to generate hydrogen by the means of transforming electric energy powered by sustainable energy into chemical energy stored in hydrogen bonds.
A team of computational scientists at the Department of Energy's Oak Ridge National Laboratory has generated and released datasets of unprecedented scale that provide the ultraviolet visible spectral properties of over 10 ...
Using the Hubble Space Telescope (HST) and the Stratospheric Observatory for Infrared Astronomy (SOFIA), astronomers have performed a multiwavelength study of a symbiotic binary known as HM Sagittae. Results of the study, ...
For the first time, researchers have succeeded in selectively exciting a molecule using a combination of two extreme-ultraviolet light sources and causing the molecule to dissociate while tracking it over time. This is another ...
