The difference between astronomy and astrophysics is that astronomy focuses on studying items outside the Earth's atmosphere, while astrophysics concentrates on the physical structures of these beings. Cosmology can be further added to this comparison, as cosmology is a branch of astronomy that looks ...
I was amazed at how many University professors in AstroPhysics (AP used for brevity, AS = Astronomy, henceforth, as primary disciplines) had almost NO familiarity with the sky at all, save object types, such as neutron stars, novae, maybe a variable or two and anything related to their res...
Astrology is a non-scientific form of entertainment that draws connections between human behavior and the alignment of the stars and planets. Astronomy and Astrophysics The difference between "astronomy" (literally "law of the stars" in Greek) and "astrophysics" (derived from the words Greek words...
Astronomy & Astrophysics manuscript no. (will be inserted by hand later) Discovery of X–rays from Venus with Chandra The observation, performed with the ACIS–I and LETG/ACIS–S instruments on Chandra, yielded data of high spatial, spectral, and temporal resolution. Venus is clearly detected ...
Finally, we use the model to test whether the difference between the magnitude of solar and stellar brightness variations reported by Lockwood et al. (1992) is due to the particular filters they use for their stellar observations. Our results suggest that this effect can explain only a small ...

Astrophysics is a branch of astronomy that mixes chemistry and physics to study celestial objects, including stars, planets, and galaxies. It differs from astronomy in one key factor: on top of observing and recording, it’s also a predictive art, forming theories on the birth, death, and mo...

(2019) noticed this difference, and attributed it to the different meaning of\(\varDelta Y\)in the two studies—maximum excursion with respect to mean difference between first- and second-generation stars, although it seems quite difficult to justify a factor of almost ten difference between ...
