Latest Metallicity Stories
Thanks to the NASA/ESA Hubble Space Telescope, some of the most mysterious cosmic residents have just become even more puzzling.
What makes one rose bush blossom with flowers, while another remains barren? Astronomers ask a similar question of galaxies, wondering how some flourish with star formation and others barely bloom.
Being hailed as a critical first step in a massive attempt to map the Milky Way, a team of European astronomers has devised a novel way to categorize stars based on their metallic composition
Most scientific calculations need a reference point to be completed, but what if the calculations are for the beginning of the universe – where points of reference are somewhat ephemeral?
New research from the Gaia-ESO project confirmed previous theories on the inside-out development of the Milky Way, which holds that the inner regions of the galaxy’s disc were the first to form.
Astronomers from the Armagh Observatory in Northern Ireland say they have discovered two unusual heavy metal stars.
The universe has had traces of heavy elements such as carbon and oxygen as far back into time as astronomers have been able to see. Elements such as these were originally churned from the explosion of massive stars.
An international team of astronomers has discovered the most-distant, super-luminous supernovae observed to date. The violent stellar explosions which caused these supernovae would have occurred soon after the Big Bang when the universe was much younger.
The brightest stars in the universe apparently do not like to live alone, according to a new study using ESO's Very Large Telescope (VLT).
Astronomers have puzzled over why some puny, extremely faint dwarf galaxies spotted in our Milky Way galaxy's back yard contain so few stars.
