To help compare different distances, this section lists lengths starting at 10 12 m (1 Tm or 1 billion km or 6.7 astronomical units). ≈1 Tm – 6.7 au – diameter of the red supergiant Betelgeuse based on multiple angular diameter estimates [186] 1.032 Tm – 6.9 au – diameter of the blue hypergiant Eta Carinae (at optical depth 2/3) [187]
At the same time, coal consumption reached new heights in China with carbon dioxide emissions from coal-fired electricity production estimated to top 4.5 billion tonnes in 2022. Reuters noted in 2022, "China is set to delight and depress climate trackers in equal measure in 2022 by setting new global records in both clean power utilisation and ...
The Mach number (M or Ma), often only Mach, (/ m ɑː k /; German:) is a dimensionless quantity in fluid dynamics representing the ratio of flow velocity past a boundary to the local speed of sound.
About 3.4 billion years ago, nitrogen formed the major component of the then-stable "second atmosphere". The influence of the evolution of life has to be taken into account rather soon in the history of the atmosphere because hints of earliest life forms appeared as early as 3.5 billion years ago.
