Earth seems like a troubled place right now, but at least our cosmic surroundings appear peaceful. This is not universally ...

TEMPOS uses Hubble’s UV observations to study massive stars in nearby metal-poor galaxies that resemble those in the early ...

The standard cosmological model (present-day version of "Big Bang," called Lambda-CDM) gives an age of the universe close to 13.8 billion years and much younger when we explore the universe at ...

In the early days of the universe, our home looked very different from how it does today. Back then, the region in our ...

JWST has revealed that galaxies were spreading carbon, oxygen, and other heavy elements through space just 500 million years ...

The two keys to Edwin Hubble 's breakthrough discovery were forged by others in the 1910s. The first key, the period-luminosity scale discovered by Henrietta Leavitt, allowed astronomers to calculate ...

When the universe was still in its infancy – only 500 million years after the Big Bang or about 3% of its current age – some ...

Are dark galaxies hiding in the nearby universe? When we look at the night sky, all the light we see – from planets to stars to nebulae and galaxies – comes from of ordinary matter. Yet astronomers ...

Exoplanet observations reveal that Earth-like rocky planets require a certain concentration of those heavier elements.

The light reaching JWST from LAP1-B began its trip about 13 billion years ago. By the time it arrived, it carried an unusually sparse chemical record. This points to a galaxy barely touched by earlier ...
