This paper summarizes the most relevant results of a thorough archaeoastronomical study conducted since 1997 in several tens of Iberian archaeological sites, most of them located in the southeast of the Iberian Peninsula. We found that a substantial fraction of the sanctuaries studied, all of them dedicated to a feminine goddess, shows a marker of

We report the discovery of K2-98b (EPIC 211391664b), a transiting Neptune-size planet monitored by the K2 mission during its Campaign 5. We combine the K2 time-series data with ground-based photometric and spectroscopic follow-up observations to confirm the planetary nature of the object and derive its mass, radius, and orbital parameters. K2-98b

High-cadence observations by the slit-jaw (SJ) optics system of the sounding rocket experiment known as the Chromospheric Lyman Alpha Spectropolarimeter (CLASP) reveal ubiquitous intensity disturbances that recurrently propagate in either the chromosphere or the transition region or both at a speed much higher than the speed of sound. The CLASP/SJ

We report on the detection, from observations obtained with the Apache Point Observatory Galactic Evolution Experiment spectroscopic survey, of a metal-poor ([Fe/H] = -1.3 dex) field giant star with an extreme Mg-Al abundance ratio ([Mg/Fe] = -0.31 dex; [Al/Fe] = 1.49 dex). Such low Mg/Al ratios are seen only among the second-generation population

We present archaeoastronomical results of an interdisciplinary project to study Bronze Age sites of the socalled Cultura de las Motillas in the Spanish region of La Mancha. We find that winter solstice sunrise was of special importance in the funerary  and perhaps religious  practises of these peoples. The impressive megalithic monumental complex
