Stellar
"Stellar" is an adjective used to describe anything related to stars, such as stellar nurseries where stars are born or stellar winds flowing from a star.
TECHNICAL DEFINITION
"Stellar" pertains to stars, their properties, evolution, and phenomena, encompassing astrophysical processes like nucleosynthesis, stellar classification (e.g., OBAFGKM), and stellar remnants.
BACKGROUND
Outer space, or simply space, is the expanse that exists beyond Earth's atmosphere and between celestial bodies. It contains ultra-low levels of particle densities, constituting a near-perfect vacuum of predominantly hydrogen and helium plasma, permeated by electromagnetic radiation, cosmic rays, neutrinos, magnetic fields and dust. The baseline temperature of outer space, as set by the background radiation from the Big Bang, is 2.7 kelvins.

USAGE NOTE
Stellar observations provide crucial data for exoplanet characterization and astrobiological research.
DEVELOPERS
Organizations developing technology related to Stellar.
Manages many of NASA's robotic space missions. JPL develops and operates spacecraft that rely on stellar navigation for precise positioning and pointing, and builds instruments for stellar and galactic observation, such as those on the Hubble and James Webb space telescopes.
An intergovernmental organization dedicated to space exploration. ESA's Gaia mission is creating the most accurate and complete multi-dimensional map of the Milky Way, charting the positions, distances, and motions of nearly two billion stars.
A manufacturer of spacecraft, instruments, and sensors. Ball Aerospace is a leading developer of high-precision star trackers, which are essential components that determine a satellite's orientation by observing star patterns.
A major aerospace and defense contractor that was the prime contractor for NASA's James Webb Space Telescope, the most powerful observatory designed to observe the earliest stars and galaxies in the universe.
A research and engineering project aiming to demonstrate proof-of-concept for light sail-propelled nanocraft for uncrewed interstellar travel. The long-term goal is to send a probe to the Alpha Centauri star system.
A subsidiary of RTX specializing in small satellites and spacecraft components. They are a prominent manufacturer of high-performance star trackers used for attitude determination on a wide range of spacecraft.
An aerospace engineering company that provides services for space mission design, development, and operation. They specialize in small spacecraft and propulsion systems which utilize stellar-based technologies for navigation and control.
Designs, manufactures, and launches rockets and spacecraft. Their Dragon and upcoming Starship vehicles are equipped with star trackers to autonomously determine their orientation in space, which is critical for docking and orbital maneuvers.
