Astrophysical plasma is plasma outside of the Solar System. It is studied as part of astrophysics and is commonly observed in space. [2] The accepted view of scientists is that much of the baryonic matter in the universe exists in this state. [3] When matter becomes sufficiently hot and energetic, it becomes ionized and forms a plasma.
The plasma of the magnetosphere has many different levels of temperature and concentration. The coldest magnetospheric plasma is most often found in the plasmasphere. However, plasma from the plasmasphere can be detected throughout the magnetosphere because it gets blown around by the Earth's electric and magnetic fields.
Artist's rendition of the Earth's plasma fountain, showing oxygen, helium, and hydrogen ions that gush into space from regions near the Earth's poles. The faint yellow area shown above the north pole represents gas lost from Earth into space; the green area is the aurora borealis , where plasma energy pours back into the atmosphere.

The launch of instruments aboard in the TWINS and IBEX missions brings the total to nine in 2009 – a 50% increase in only 4 years. Space plasma observation using ENA imaging is an emerging technology that is finally coming into its own. Several improvements are still needed to perfect the technique.
In 2021, Nasa's Office of Inspector General (OIG), which provides oversight of the space agency for Congress, reported that the cost was $4.1bn (£3.3bn) for each and every launch.
Escape and Plasma Acceleration and Dynamics Explorers (ESCAPADE) is a planned spacecraft mission to Mars consisting of two spacecraft known as Blue and Gold. [3] [2] The mission, once expected to launch in October 2024, is part of NASA's SIMPLEx program.
A nova, a rare astronomical event, could be visible soon. It won't last long, and it won't occur again for several decades. How to see it in 2024.
