Space telescope Imaging Spectrograph
We acquired spectra of 24 LMC PNe in the 1150–3000 Å range in order to determine carbon and other ionic abundances. The sample more than doubles the number of LMC PNe with good quality UV spectra in this wavelength range, and whose optical images are available in the HST archive. The Space Telescope Imaging Spectrograph was used with a very large aperture to obtain virtually slit-less spectra, ...
متن کاملModular assembled space telescope
We present a new approach to building a modular segmented space telescope that greatly leverages the heritage of the Hubble Space Telescope and the James Webb Space Telescope. The modular design in which mirror segments are assembled into identical panels allows for economies of scale and for efficient space assembly that make a 20-m aperture approach cost effective. This assembly approach can ...
متن کاملIn-Between Space, Dialectic of Inside and Outside in Architecture
Defining space by dividing it to inside and outside is one of human’s ways to recognize his positionin environment. Architecture is created to response to this need for inside/outside spaces. Design of inside and outsideSpaces and relation between them always has been one of necessities for definition and limitation of human livingspaces, but little attention to relation of this two spatial rea...
متن کاملThe James Webb Space Telescope
The scientific capabilities of the James Webb Space Telescope (JWST) fall into four themes. The End of the Dark Ages: First Light and Reionization theme seeks to identify the first luminous sources to form and to determine the ionization history of the universe. The Assembly of Galaxies theme seeks to determine how galaxies and the dark matter, gas, stars, metals, morphological structures, and ...
متن کاملCOSMOS : Hubble Space Telescope Observations
The Cosmic Evolution Survey (COSMOS) was initiated with an extensive allocation (590 orbits in Cycles 12-13) using the Hubble Space Telescope (HST) for high resolution imaging. Here we review the characteristics of the HST imaging with the Advanced Camera for Surveys (ACS) and parallel observations with NICMOS and WFPC2. A square field (1.8⊓⊔) has been imaged with single-orbit ACS I-F814W expos...
