Long-term Variation of Solar Activity by a Dynamo Based on Magnetic Flux Tubes
We show that cyclic activity and Maunder-type grand minima can be explained by a dynamo driven by the instability of magnetic flux tubes in the overshoot layer...
Looking back at Earth, from Earth, during a lunar eclipse
A lunar eclipse offers a unique opportunity to investigate the Earth's atmosphere. Even at its darkest, the Moon in umbra is still lit by solar photons...
The rationale for looking for prokaryote fossils in Martian materials is based on our present understanding of the environmental evolution of that planet in...
Looking for the sun within the educational core standards: the Spanish case
Although Astronomy is engaging and motivating for both precollege and college students, it is often difficult to fit it in within the formal educational core...
Looking for the traces of the early Universe in the Fornax dSph galaxy
We present the full Star Formation History as a function of radius of the Fornax dSph galaxy. We also present the preliminary results of the spatial...
