The thick disk began forming stars just 0.8 billion years after the Big Bang. When you purchase through links on our site, we may earn an affiliate commission. Here’s how it works. James Webb ...

An international team of astronomers has identified for the first time a thick stellar disc in the Andromeda galaxy, the nearest large spiral galaxy to our own Milky Way. An international team of ...

Scientists have discovered that parts of the Milky Way galaxy are actually older than previously thought — at least by two billion years. Data collected by the European Space Agency’s (ESA) Gaia ...

Disk galaxies, like our own Milky Way galaxy, commonly consist of both a thick and thin disk of stars—each with different features, including stellar population and movement. Three major theoretical ...

Using the James Webb Space Telescope, scientists spotted thin and thick disks in galaxies as far back as 10 billion years ago—something never seen before. These observations reveal that galaxies first ...

The figures illustrate the revealed sequential disk formation in this study: thick disk only galaxies dominate the early epochs (bottom panel), while galaxies exhibiting both thin and thick disks ...

A new analysis of nearly a quarter million stars puts firm ages on the most momentous pages from our galaxy’s life story. Far grander than most of its neighbors, the Milky Way arose long ago, as ...

However, scientists think this process alone is not enough. “Scattering from giant molecular clouds can heat thin-disc stars, but it does not create an entire thick disc,” the paper explained. Mergers ...

When looking up at the sky, you might think galaxies have always looked the way they do today. But a new study from Princeton University and published in the journal, Monthly Notices of the Royal ...
