- The Sun (stars.astro.illinois.edu)
Similar in many languages, “Sun,” related to Latin’s “sol,” was represented in ancient Greece as Helios, god of the Sun. Giver of warmth and life, we hardly think of the Sun as a star, the term “Sun and stars” in constant use, though the surmise that it is a star goes back to ancient times.
- A Bubbly Origin for Stars around the Sun (youtube.com)
This video describes new research linking an interstellar void known as the Local Bubble to nearby star-forming regions. It begins by zooming into an artistโs rendering of the Milky Way to our own galactic neighborhood. Next, an animation beginning 14 million years ago steps through time to show how a series of supernovas created the Local Bubble. As the bubble expands, it sweeps up gas and dust that condense to form star clusters. The video then resets to 14 million years ago and steps forward again to show how the Sunโs path through the Milky Way galaxy brought it into the Local Bubble about 5 million years ago. Today, weโre coincidentally close to the middle of the bubble. Finally, the video pans around a 3D model of the Local Bubble and associated star-forming regions as they exist today.

- Sun (Wikipedia)
The Sun is the star at the center of the Solar System. It is a massive, hot ball of plasma, inflated and heated by energy produced by nuclear fusion reactions at its core. Part of this internal energy is emitted from its surface as light, ultraviolet, and infrared radiation, providing most of the energy for life on Earth.
