Thanks to the NASA/ESA Hubble Space Telescope, some of the most mysterious cosmic residents have just become even more puzzling.

Window To Early Universe Offered By Slow-Growing Galaxies

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.

Star Measurement Made Easier With A Novel Spectral Ruler

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

Using Simulations To Chart The Forces Of The Early Universe

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?

ESA Confirms Inside Out Model Milky Way

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.

First Stars Born Short 750 Million Years After The Big Bang

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.

Rare Supernovae Are The Most Luminous Ever Observed

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.

New research using data from ESO’s Very Large Telescope has revealed that the hottest and brightest stars, which are known as O stars, are often found in close pairs. Many of such binaries transfer mass from one star to another, a kind of stellar vampirism depicted in this artist’s impression. Credi
