It takes highly sensitive (expensive) cameras to
capture the faint light of, say, a distant galaxy.

Hubble
captured images of the galaxy in visible and infrared
light, witnessing a new bright object within NGC 4993 that was brighter than a nova but
fainter than a supernova.
* The
faint light emitted can be
captured by a mobile - phone camera, making it easy to share with clinicians — no complex lab equipment required.
Using data
captured by ALMA in Chile and from the ROSINA instrument on ESA's Rosetta mission, a team of astronomers has found
faint traces of the chemical compound [Freon - 40]--(CH3Cl), also known as methyl chloride and chloromethane, around both the infant star system IRAS 16293 - 2422, about 400
light - years away, and the famous comet 67P / Churyumov - Gerasimenko (67P / C - G) in our own Solar System.
The galaxies are the smallest,
faintest, and most numerous galaxies ever seen in the remote universe, and were
captured by Hubble deep exposures taken in ultraviolet
light, and confirmed using the mighty Keck I telescope on the summit of Mauna Kea on the island of Hawaii.
While spectroscopy of extremely
faint sources is not trivial the primary technology challenge, the «tall tent pole», is starlight suppression — blocking the bright
light from the target star so as to
capture the
faint reflected
light of the exoplanet.
Thus, any attempt to
capture the
faint Na
light by long time - exposures would result in a highly blurred image.
To
capture the
faint signals from sodium atoms close to Io, the observers had to find a way to cope with the bright sunlight reflected from Io's surface, as well as from the even stronger
light from nearby Jupiter.
In an ongoing series, Finch
captures the changes in natural
light on his studio wall through
faint washes of paint — recalling Mondrian's concern with moments of transition, the
captured half -
lights of twilights and sunsets.
