Space weather. Space weather is a branch of space physics and aeronomy, or heliophysics, concerned with the varying conditions within the Solar System and its heliosphere. This includes the effects of the solar wind, especially on the Earth's magnetosphere, ionosphere, thermosphere, and exosphere. [ 1]
July 7: Astronomer Anthony Boccaletti discusses observation of birth of potential exoplanet with Wikinews. May 31: SpaceX successfully launches its first crewed spaceflight.

Stellar evolution is the process by which a star changes over the course of its lifetime and how it can lead to the creation of a new star. Depending on the mass of the star, its lifetime can range from a few million years for the most massive to trillions of years for the least massive, which is considerably longer than the current age of the ...
The International Astronautical Congress ( IAC) is an annual meeting of the actors in the discipline of space science . It is hosted by one of the national society members of the International Astronautical Federation (IAF), with the support of the International Academy of Astronautics (IAA) and the International Institute of Space Law (IISL).
The atmosphere of Earth is composed of a layer of gas mixture that surrounds the Earth's planetary surface (both lands and oceans ), known collectively as air, with variable quantities of suspended aerosols and particulates (which create weather features such as clouds and hazes ), all retained by Earth's gravity.
Outer space. Being essentially empty, outer space allows the earliest (redder) galaxies to be viewed without obstruction, as in the Webb's First Deep Field image. Outer space (or simply space) is the expanse that exists beyond Earth's atmosphere and between celestial bodies. [ 1] It contains ultra-low levels of particle densities, constituting ...
The politics of outer space includes space treaties, law in space, international cooperation and conflict in space exploration, international economics, and the hypothetical political impact of any contact with extraterrestrial intelligence . Astropolitics has its foundations in geopolitics and is a theory that is used for space in its broadest ...
Planetary surfaces are found on solid objects of planetary mass, including terrestrial planets (including Earth ), dwarf planets, natural satellites, planetesimals and many other small Solar System bodies (SSSBs). [ 1][ 2][ 3] The study of planetary surfaces is a field of planetary geology known as surface geology, but also a focus on a number ...
