Several research teams will use
Webb to explore the mysterious nature of brown dwarfs. Webb is an international
project led by NASA with its partners, ESA (European Space Agency) and CSA
(Canadian Space Agency). However, Previous work with Hubble, Spitzer, and ALMA
have shown that brown dwarfs can be up to 70 times more massive than gas
giants like Jupiter, yet they do not have enough mass for their cores to burn
nuclear fuel and radiate starlight. For discovering the mysteriousness research
will find out more deeply with using Webb.
These observations could lay groundwork for future exoplanet
exploration with Webb, including which worlds could support life. The search
for the brown dwarfs has a lower mass than stars and do not “shine” but merely
emit the dim afterglow of their birth, and so they are best seen in infrared
light, which is why Webb telescope will be such a valuable tool in this
research. The projects led by Scholz and Artigau are making use of Guaranteed
Time Observations (GTOs), observing time on the telescope that is granted to
astronomers who have worked for years to prepare Webb’s scientific operations.
The James Webb Space Telescope, the scientific complement to
NASA's Hubble Space Telescope, will be the premier space observatory of the
next decade.
