The MEGARA IFU (also called the Large Compact Bundle, or LCB) offers a contiguous field of view of 12.5 arcsec x 11.3 arcsec, while the multi-object spectroscopy mode allows 92 objects to be observed simultaneously in a field of view of 3.5 arcmin x 3.5 arcmin by means of an equal number of robotic positioners. Both the LCB and MOS modes make ...
Looming of the Canadian coast as seen from Rochester, New York, on April 16, 1871. Looming is the most noticeable and most often observed of these refraction phenomena. It is an abnormally large refraction of the object that increases the apparent elevation of the distant objects and sometimes allows an observer to see objects that are located below the horizon under normal conditions.
The real object in an inferior mirage is the (blue) sky or any distant (therefore bluish) object in that same direction. The mirage causes the observer to see a bright and bluish patch on the ground. Light rays coming from a particular distant object all travel through nearly the same layers of air, and all are refracted at about the same angle ...
Mysterious lights were filmed in the sky at the National Women's Soccer League semi-final playoff match between San Diego Wave FC and OL Reign in San Diego on Sunday, 5 November. But rather than ...
The reason for this apparent reduction in sky brightness is that, while light from the sky enclosed within the primary bow comes from droplet reflection, and light beyond the secondary bow also comes from droplet reflection, there is no mechanism for the region between the bows to reflect light in the direction of the observer. Generally ...
The Solar and Heliospheric Observatory (SOHO) in a halo orbit around L1 . Mission: Investigation of the outer layer of the Sun, making observations of solar wind and associated phenomena in the vicinity of L1, probing the interior structure of the Sun.
Several types of astrophysical objects emit X-rays, from galaxy clusters, through black holes in active galactic nuclei to galactic objects such as supernova remnants, stars, and binary stars containing a white dwarf (cataclysmic variable stars), neutron star or black hole (X-ray binaries).
“The shallower slide does have fast movement, but the deeper slide is moving much faster,” Awwad said. "The priority becomes that deeper slip plane.” The discovery only exacerbates the sense ...
