Spectroscopic observations from the W. M. Keck Observatory on Maunakea, Hawaii and the Very Large Telescope in Chile confirmed the four candidates to be massive clusters.
Not exact matches
But telescopic and
spectroscopic observation, and increasingly exact calculations, are transforming this comfortable spectacle into a vision that is very much more unsettling, one which in all probability will profoundly affect our moral outlook and religious beliefs when it has passed
from the minds of a few initiates into the mass - consciousness of Mankind as a whole: immensities of distance and size, huge extremes of temperature, torrents of energy...
Materials known to exist at Pluto's surface
from ground - based
spectroscopic observations include highly volatile cryogenic ices of N2 and CO, along with somewhat less volatile CH4 ice, as well as H2O and C2H6 ices and more complex tholins that are inert at Pluto surface temperatures.
Measurements of surface chemical composition, either by direct sampling (as has been done on Earth, the moon, and Mars) or through
spectroscopic observations, can be used to estimate elemental abundances and the degree of chemical differentiation that occurred as the planets condensed
from the solar nebula.
Spectroscopic observations revealed that the planet is only about three to four times the size of the star — but its hydrogen emissions are almost as bright as the emission emanating
from the star.
The results of follow - up
observations (see Table 2) are a mixture of results
from photometric follow - up (Deeg et al. 2009), which identifies contaminating» diluted EB's that are more than about 2 distant
from the third star - which usually coincides with the observing target -, and
from spectroscopic (radial velocity) results, which can only identify signals
from sources that fall into the spectrograph's entry slit; that is, they have to be very close (less than 1 - 2) to the target.
Spectroscopic observations taken with the GTC - 10.4 m telescope reveal a broad (FWHM ~ 1100 km / s), double - peaked H alpha emission line
from which we constrain the radial velocity semi-amplitude of the donor to be K2 > 250 km / s.

Observations
MATISSE is a four - way beam combiner, meaning it combines the light collected
from up to four of the Unit Telescopes or up to four of the Auxiliary Telescopes that make up the VLTI, performing both
spectroscopic and imaging
observations.
To further investigate, astronomers led by Nanda Rea of the University of Amsterdam sought help
from NASA's Chandra and Nuclear
Spectroscopic Telescope Array, or NuSTAR, to follow up with the
observations.
Using the twin telescopes of the Keck Observatory on Maunakea, Hawaii, the researchers were able to gather
spectroscopic data
from the afterglow of the supernova and
observations of its host galaxy to better understand what might be driving this oddity.
Here, we use
observations from the Large Sky Area Multi-Object Fibre
Spectroscopic Telescope (LAMOST, also called the Guoshoujing Telescope at Xinglong observatory, China) 33 to show that superflare stars are generally characterized by larger chromospheric emissions than other stars, including the Sun.
The baffling and strange behaviours of black holes have become somewhat less mysterious recently, with new
observations from NASA's Explorer missions Swift and the Nuclear
Spectroscopic Telescope Array, or NuSTAR.
Current research in the Hida Observatory of Kyoto University has emphasis on the followings; (a) Study of solar MHD processes with
spectroscopic and spectro - polarimetric
observations using the 60 cm Domeless Solar Vacuum Tower Telescope (DST) combining with data
from space solar missions (such as Hinode).
The evidence for this is a mountain of
spectroscopic data about the behaviour of the greenhouse gases
from laboratory
observations, ground level
observations, high altitude aircraft
observations and more recently satellite
observations.
The «clear sky radiative forcing due to CO2» (3.7 W / m ^ 2 for a doubling per Myhre et al. 1998b and IPCC TAR) is not a measured entity based on empirical data
from actual physical
observations or reproducible experimentation, but rather an estimated value based on laboratory studies of
spectroscopic data.
