As a branch of astronomy, star formation includes the study of the interstellar medium (ISM) and giant molecular clouds (GMC) as precursors to the star formation process, and the study of protostars and …

May 2, 2025 · After millions of years, immense pressures and temperatures in the star’s core squeeze the nuclei of hydrogen atoms together to form helium, a process called nuclear fusion. Nuclear fusion …

Nov 13, 2025 · Learn how stars form from collapsing gas clouds and evolve through stages like the main sequence, red giant, and supernova in this guide to stellar evolution.

Oct 13, 2023 · How are stars formed? In this article we'll explain stars and learn how stars are formed.

Discover how do stars form in space through gravitational collapse, molecular cloud compression, and nuclear fusion and see all the stages!

Aug 23, 2025 · The heavier elements—carbon, oxygen, iron—present in trace amounts within the cloud were formed in earlier generations of stars, then spread across the galaxy by supernova explosions.

May 30, 2024 · Understanding star formation is fascinating as it reveals how simple clouds of cosmic material transform into the dazzling stars we see. So, let’s dive into the detailed steps of how stars …

Star formation happens in interstellar molecular clouds: opaque clumps of very cold gas and dust. The process starts when some of those clumps reach a critical mass, allowing them to collapse under …

Jan 11, 2026 · The protostar then becomes a main-sequence star. Once a star reaches the main-sequence stage, it begins to fuse hydrogen into helium in its core, releasing energy in the process. …

Apr 28, 2025 · How does that work, and how do stars form in the first place? Let's take a tour of one of the universe's most defining, beautiful, and enduring objects—including our own Sun.
