A new study from the NASA New Huraizon mission team at the Southern West Research Institute resulted in a map of the first type of Milky Way galaxy In the wavelength of UV rays, details are revealed in the area around us Solar power system.
What is this?
Imagine this spectrum map, which was created from the data collected by the new NASA prospect, the relatively unified brightness of the surrounding “Lyman-Alpha” background Sun And its influence area.
“Understanding the background of Lehman Alfa helps to shed light on nearby Hungarian structures and operations,” said Dr. Randy Gladston of the Southwestern Research Institute (SWRI) in Colorado. “This research indicates that the gas bubbles between hot stars such as those whose solar system is actually included in reality may actually be areas of reinforced hydrogen gas emissions at a wave length called Lyman Alpha.”
Lyman-Alpha is a specific wavelength of UV light emitted and widespread with hydrogen atoms. It is useful when studying is far Starsand Galaxies and The middle of the starsBecause it can help discover the composition, temperature and movement of these distant things.
On this spectrum map, black points represent approximately 90,000 well -known UV stars in our galaxy.
Where is she?
New horizonsThat started as the first mission to fly PlutoThe foundation line data was collected on Lyman-Alpha emissions during its initial journey to the small iceberg.
After completing the initial targets of the Pluto spacecraft, the New Horizons (named “” Alice “) is used to make more frequent surveys of Lyman-Alpha emissions where the New Horizons traveled beyond the sun. These notes included a wide range of surveying operations in 2023, which identified about 83 % of the sky.
Why is it amazing?
Before the launch of this map, scientists theoretically made that a wall of hydrogen atoms between the stars will accumulate when they reached the edge of the healviri – our galaxy area where Solar wind From our sun arrives and interacts with the medium between the stars. New Horizons has not seen anything to indicate that this “wall” was an important source of Lehman Alpha emissions.
“These are really prominent notes, in giving the first clear offer to the sky surrounding the solar system in these wavelengths, both of which reveal new characteristics of that sky and refute old ideas that are not supported by Alice New horizons,” said Dr. Alan Stern. The main investigator of the mission at SWRI. “Lyman-Alpha map also provides a solid basis for future investigations to learn more.”
