Galaxy in the early universe contains carbon after all
In 2015, Jorryt Matthee thought he discovered an extremely distant galaxy called CR7, which lacked elements heavier than helium. Three years later, he shows with measurements using the ALMA telescope that the galaxy does ...
Tellurium is detected in one of its places of origin
An international team led by a Ph.D. student from the Instituto de Astrofísica de Canarias (IAC) and the University of La Laguna (ULL) has identified the emission of tellurium in the infrared spectra of two planetary nebulae ...
Collisions of dead stars spray heavy elements throughout small galaxies
Caltech scientists have found, for the first time, that merging pairs of neutron stars—the burnt-out cores of stars that have exploded—create the majority of heavy elements in small "dwarf" galaxies. Heavy elements, such ...
Using the K computer, scientists predict exotic "di-Omega" particle
Based on complex simulations of quantum chromodynamics performed using the K computer, one of the most powerful computers in the world, the HAL QCD Collaboration, made up of scientists from the RIKEN Nishina Center for Accelerator-based ...
Stellar embryos in nearby dwarf galaxy contain surprisingly complex organic molecules
The nearby dwarf galaxy known as the Large Magellanic Cloud (LMC) is a chemically primitive place.
Special star is a Rosetta Stone for understanding the sun's variability and climate effect
The spots on the surface on the sun come and go with an 11-year periodicity known as the solar cycle. The solar cycle is driven by the solar dynamo, which is an interplay between magnetic fields, convection and rotation. ...
Image: Dwarf galaxy Kiso 5639
In this NASA/ESA Hubble Space Telescope image, a firestorm of star birth is lighting up one end of the dwarf galaxy Kiso 5639.
Piercing the mystery of the cosmic origins of gold
Where does gold, the precious metal coveted by mortals through the ages, come from? How, where and when was it produced? Last August, a single astrophysical observation finally gave us the key to answer these questions. The ...
Rapid-response program to explore a double neutron star merger
Two years ago, scientists from the Laser Interferometer Gravitational-Wave Observatory (LIGO) detected gravitational waves for the first time, proving Einstein's theory of relativity and his prediction of their existence. ...
