Stars

Artist's illustration of the Local Bubble with star formation occurring on the bubble's surface. Scientists have now shown how a chain of events beginning 14 million years ago with a set of powerful supernovae led to the creation of the vast bubble, responsible for the formation of all young stars within 500 light years of the Sun and Earth.

There is a Giant Bubble Surrounding the Earth and the Solar System. It is 1,000 -light-year wide and is a source of all young, nearby stars.

Brown Dwarfs – Planets, stars, or something entirely different? Scientists think they lie between the two and can't fuse hydrogen.

The galaxy AGC 114905. The stellar emission of the galaxy is shown in blue. The green clouds show the neutral hydrogen gas. The galaxy does not appear to contain any dark matter, even after 40 hours of detailed measurements with state-of-the-art telescopes. Credit: (c) Javier Román & Pavel Mancera Piña
