Peering Into a Starburst Galaxy with JWST

Peering Into a Starburst Galaxy With the JWST

Astronomers used the JWST to examine M82, a nearby starburst galaxy. M82 is forming stars at a prodigious rate due to its interactions with its neighbour, M81. It produces thousands of solar masses of stars per year, much more than the Milky Way.

When it comes to star formation, not all galaxies are the same. Some are quenched, meaning they've depleted their star forming gas and form very few new stars. Some, like the Milky Way, are typical and form stars at an average rate. But some are extremely active, and form stars so readily they're called starburst galaxies.

JWST unlocks 10-billion-year mystery of how galaxies shape themselves

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 formed thick, chaotic disks, and only later developed the calm, thin disks seen in modern spirals like the Milky Way.

JWST reveals how galaxies like the milky way built their stellar disk over time

A new study using images from the James Webb Space Telescope (JWST) has helped to answer a continuous question in astronomy Astronomers have been able to identify both thin and thick stellar disks in galaxies, extending far beyond our local universe, with some dating back 10 billion years The research was led by an international team and recently published in the Monthly Notices of the Royal Astronomical Society. It analysed 111 edge-on galaxies…
