Relationship of the atmosphere and ionosphere. The ionosphere (/ aɪ ˈ ɒ n ə ˌ s f ɪər /) [1] [2] is the ionized part of the upper atmosphere of Earth, from about 48 km (30 mi) to 965 km (600 mi) above sea level, [3] a region that includes the thermosphere and parts of the mesosphere and exosphere.
The thermosphere in this range has ... The tally of molecules discovered through radio astronomy is steadily ... starting at 2 billion years and 280 million light-years.
The thermosphere extends from an altitude of 85 km to the base of the exosphere at 690 km and contains the ionosphere, where solar radiation ionizes the atmosphere. The density of the ionosphere is greater at short distances from the planetary surface in the daytime and decreases as the ionosphere rises at night-time, thereby allowing a greater ...

The newly-discovered thick atmosphere gives the planets another thing in common. ... GJ 1132b orbits around the dwarf star GJ 1132 about 39 light-years away from our solar system.
With the help of two powerful radio telescopes, astronomers spotted the gigantic two-lobed jet, which spans at least 200,000 light-years. A light-year is the distance light travels in one year ...
A light-year, alternatively spelled light year (ly or lyr [3]), is a unit of length used to express astronomical distances and is equal to exactly 9 460 730 472 580.8 km, which is approximately 9.46 trillion km or 5.88 trillion mi.
