The discovery that the 1000-light-year-wide “Local Bubble” surrounding the Sun and Earth is responsible for the formation of all nearby, young stars was first presented in a paper published in Nature on January 12, 2022.

And, if we forgot something, just let us know—and we’ll try to include it in future updates!
- Solid (Wikipedia)
Solid is one of the four fundamental states of matter along with liquid, gas, and plasma. The molecules in a solid are closely packed together and contain the least amount of kinetic energy. A solid is characterized by structural rigidity (as in rigid bodies) and resistance to a force applied to the surface. Unlike a liquid, a solid object does not flow to take on the shape of its container, nor does it expand to fill the entire available volume like a gas. The atoms in a solid are bound to each other, either in a regular geometric lattice (crystalline solids, which include metals and ordinary ice), or irregularly (an amorphous solid such as common window glass). Solids cannot be compressed with little pressure whereas gases can be compressed with little pressure because the molecules in a gas are loosely packed.
