Astronomy.

La Astronomía estudia el universo por medio de telescopios y sondas espaciales. Se compone de diferentes disciplinas como la astrobiología, la cosmología y la astrofísica. Aquí se explica cómo ayuda a desentrañar los secretos del espacio y debatir sobre cómo empezó el universo, cuál será su final y la posibilidad de vida en otros planetas.

Astronomy.

Examina la historia de esta ciencia considerada la más antigua de todas por el interés que desde la antigüedad ha suscitado en los hombres el conocimiento de los complejos movimientos de los objetos celestiales.También, se repasan los orígenes del universo con la violenta explosión ocurrida hace billones de años, llamada Big Bang. Se estudia el sistema solar, formado de planetas, lunas e innumerables cuerpos más pequeños como asteroides y cometas. Se completa con una observación de las estrellas y galaxias en el cielo de la noche, con cartas estelares y perfiles de constelaciones y, por último, se añade una guía con la posición mes a mes de las constelaciones septentrionales y australes.

Patrick Moore's astronomy.

Guía que proporciona todo lo que se necesita saber para investigar el Sol, Luna, cometas, planetas y estrellas, y aprender a observarlos. Cada capitulo se inicia con información sobre lo que se va a aprender, y termina con lo que se debe recordar.

Interference filters and coatings for mid-infrared astronomy (8-30µm)

The VISIR instrument for the European Southern Observatory (ESO) Very Large Telescope (VLT) is a thermal-infrared imager and spectrometer currently being developed by the French Service d'Astrophysique of CEA Saclay, and Dutch NFRA ASTRON Dwingeloo consortium. This cryogenic instrument will employ precision infrared bandpass filters in the N-( =7.5-14µm) and Q-( =16-28µm) band mid-IR atmospheric windows to study interstellar and circumstellar environments crucial for star and planetary formation theories. As the filters in these mid-IR wavelength ranges are of interest to many astronomical cryogenic instruments, a worldwide astronomical filter consortium was set up with participation from 12 differing institutes, each requiring instrument specific filter operating environments and optical metrology. This paper describes the design and fabrication methods used to manufacture these astronomical consortium filters, including the rationale for the selection of multilayer coating designs, temperature-dependant optical properties of the filter materials and FTIR spectral measurements showing the changes in passband and blocking performance on cooling to <50K. We also describe the development of a 7-14µm broadband antireflection coating deposited on Ge lenses and KRS-5 grisms for cryogenic operation at 40K

Cooled filters 16-42µm for FIR astronomy

The design and manufacture of dielectric-film interference filters for cooled FIR stronmy is described. The bands are 16.5-21.5µm, 17.5-19.5µm, 19.5-21.5µm and 27µm cut on. The films are PbTe/CdSe and the substrates are CdTe (some 1/2 mm thick), without absorption in the region: KRS-6 films are used for antireflection.

A constructivist approach to the teaching & learning of astronomy

Astronomy is one of the recurrent contemporary issues in the mass media where news related to comets, new stars, satellites, space tests, etc., frequently appear. Through this media presence students develop an interest in learning about aspects of astronomy. However, the information students gain from various sources, both inside and outside the classroom, doesn't often increase their knowledge about the most basic and common aspects of astronomy (Martinez Pena & Gil Quilez, 2001). Studies that have explored students' and teachers' understandings of astronomical concepts (Kalkan et al, 2007; Trumper, 2001) have found many alternative conceptions relating to basic astronomical processes such as day and night, the seasons, gravity and the relative distances between celestial objects.

Year 8 students' understanding of astronomy as a representational issue : insights from a classroom video study

The research described in this paper argues that difficulties of leaming science concepts such as those associated with processes involving the Sun, Moon and Earth, such as day and night, the seasons and phases of the moon, are fundamentally representational in nature. There is a need for learners to use their own representational, cultural and cognitive resources to engage with the subject-specific representational practices of science. From this perspective students need to understand and conceptually integrate different representational modalities or forms in learning science and reasoning in science. The researchers worked with two experienced teachers in planning a teaching sequence in astronomy using a teaching approach that highlight representational issues and options in helping students explore and develop key conceptual understandings. Classroom sequences involving the two teachers were videotaped using a combined focus on the teacher and groups of students. Video analysis software was used to capture the variety of representations used, and sequences of representational negotiation. From a pedagogical perspective the representational approach placed a significant agency in the hands of students which resulted in structured discussions around conceptual problems. Representations were used as tools for reasoning and communication to drive classroom discussions and develop higher levels of understanding in the students. The pre- and post-testing showed significant gains in students thinking from naive to more scientific understandings of astronomy.

Traces from the astrolabe: art and astronomy

This portfolio represent an ongoing investigation into relationships between art and astronomy with particular reference to photographic imaging of the cosmos and how such imaging has influenced the mapping and modelling of the universe. I am also interested in the subjective interpretation of astronomical observations and the point at which such images fail to represent, ie, the blurred image, which may represent the limits of technology as well and opening the possibility for metaphorical readings and imaginings on the part of the observer.
