Using the Gemini Observatory, Argentinian astronomers have conducted comprehensive photometric and spectroscopic observations of an early-type dwarf galaxy known as CGCG014-074. Results of the observational campaign, published ...
Astronomers have performed photometric observations of a young globular cluster known as NGC 1851. The new observational campaign provides more insights into the variable star population of this cluster and validates the ...
An international team of astronomers reports the detection of a blazar with highly significant sinusoidal radio variability using the Owens Valley Radio Observatory (OVRO). The finding was detailed in a research paper published ...
Are there any advanced alien civilizations elsewhere in our galaxy? We don't know. All we do know is that there is at least one. Should we be optimistic or pessimistic about finding others?
Astronomers from the Pennsylvania State University (PSU) and elsewhere have observed an X-ray binary system known as CXOU J005245.0-722844. They detected an X-ray outburst from this binary and found that it harbors a white ...
Extensive geologic evidence of ancient volcanic activity can be found on the moon, but how long this volcanism persisted has been unclear. However, Prof. Li Qiuli's Lab at the Institute of Geology and Geophysics of the Chinese ...
