Astrophysicists focused on the Sun as a model cool star to bridge this gap. For the first time, they successfully determined ...

This limitation has led to long-standing assumptions and uncertainties regarding the precise ratio of Helium to Hydrogen (He/H) in the Sun's surface layer.

Astronomers have uncovered a discovery that could reshape our understanding of the early Universe. Using the James Webb Space ...

Lyman-alpha emission is a specific spectral line produced when electrons in hydrogen atoms transition from a high energy level to a lower one. It's often used to detect young galaxies and quasars.

Dr. Moriwaki was the first in the world to point out the importance of observing oxygen spectral lines rather than the traditional hydrogen spectral lines in order to elucidate the large-scale ...

Studying the line spectra produced by hot gases and absorbed by cooler gases allows us to identify the elements in stars. When a gas is very hot, it doesn’t emit all wavelengths of light.

Officially launched at the country's Zhongshan Station in Antarctica on April 3, the telescope, co-developed by China Three Gorges University (CTGU) and Shanghai Normal University (SHNU), further ...
