The James Webb Space Telescope (JWST) of NASA has discovered an unexpectedly rich realm of early galaxies. It had previously been largely hidden, beyond the reach of other telescopes. Researchers discovered two extremely bright galaxies that existed between 350 and 450 million years after the...

Astronomers examined photometric and spectroscopic observations of OGLE-BLG504.12.201843

An international team of Astronomers examined photometric and spectroscopic observations of OGLE-BLG504.12.201843, a candidate cataclysmic variable. According to the findings of this analysis, this object is an extreme dwarf nova of the U Gem type. The findings are detailed in a paper published on...

Study unveils stellar population properties of galaxies in LAMOST spectral survey

Dezhou University scientists have derived the age and metallicity of the stellar populations of about 43,000 galaxies in DR7 of LAMOST spectral survey. They have derived it based on the LAMOST data. The derived results have been included in a LAMOST value-added catalog. It has enriched the...
