As Webb observes light that's traveled from the far reaches of the cosmos, it captures
images of distant stars and forming galaxies as they were in the earliest stages of the universe.

The field is so small that only a few foreground
stars in the Milky Way lie within it; thus, almost all
of the 3,000 objects in the
image are galaxies, some
of which are among the youngest and most
distant known.
Taking an optical
image of distant planets is tough because the bright light from their
stars drowns them out.
Gravity from a galaxy (box) in this Hubble Space Telescope
image bends light from a more
distant supernova, creating four
images of the exploding
star (arrows).
For the first time, astronomers have
imaged a cosmic microlens, an object that increases the brightness
of distant stars.
When Sigurdsson and colleagues analyzed
images of the white dwarf from the Hubble Space Telescope, they concluded that the
distant, unseen companion is not a low - mass
star, as many researchers had thought, but a planet with about 2.5 times the mass
of Jupiter.
For example, an instrument on one satellite could block the glare
of the sun or a
distant star, making it possible for a camera on the other to
image faint objects such as the sun's ghostly corona or exoplanets orbiting a
star.
A device called a coronagraph can be built into a telescope to block most
of the photons from a
distant star's glow, allowing the dim light from a planet to pass into the telescope's sensors and create a glare - free
image.
In a gravitational lens, the gravity
of stars and other matter can bend the light
of a much more
distant star or galaxy, often fracturing it into several separate
images (see
image at right).
If the light from a
distant galaxy reaches us having passed through a cluster
of say, four
stars, she wondered, then how many
images might we see?
(In the
image above the more
distant quasar HE 1104 - 1805 is seen as the two larger
images on either side
of the smaller yet closer lens galaxy [WKK93] G.) The
stars in that lens galaxy then act like ultra-high resolution telescopes (see the NASA video).
The
images present a striking record
of historic solar and lunar eclipses, comets, and even views
of binary
stars and
distant constellations.
«First look at birthplaces
of most current
stars: Highly sensitive
images reveal details
of distant galaxies.»
A new
image of gas around the most
distant black hole known suggests that it arose without many
stars around it.
Such slavering was perhaps unsurprising, given that suspended animation has often been associated with sci - fi
images of astronauts hibernating in pods en route to
distant stars.
Like astronomers tweaking
images to gain a more detailed glimpse
of distant stars, physicists at Brookhaven National Laboratory have found ways to sharpen
images of the energy spectra in high - temperature superconductors â $» materials that carry electrical current effortlessly when cooled below a certain temperature.

image (Artwork from Extrasolar Visions, used with permission from Whatmough) Glowing red through gravitational contraction, the candidate brown dwarf companion to Proxima Centauri is depicted with two moons (one eclipsing the flare
star) with
distant Alpha Centauri A and B at upper right, as imagined by Whatmough.
MAUNA KEA, HI — Astronomers have for the first time spotted four
images of a
distant exploding
star, arranged in a cross-shape pattern by a powerful gravitational lens.
Astronomers are stuck with such indirect methods
of detection because current telescope technology struggles to
image very
distant and faint objects - especially when they orbit close to the glare
of a
star.
AO has measured the mass
of the giant black hole at the center
of our Milky Way Galaxy,
imaged the four massive planets orbiting the
star HR8799, discovered new supernovae in
distant galaxies, and identified the specific
stars that were their progenitors.
Just this year it captured the most
distant single
star yet, learned more about a strange stellar ring, watched two galaxies merge, and created lots
of new
images of the Messier objects, the
distant smudges first described by astronomer Charles Messier in the 18th century.
