FROM THE EDITOR
A new era in astronomy
In mid-July 2022, the astronomy
world was turned on its ear by a first
release of five images from the James
Webb Space Telescope (JWST). Launched on
Christmas Day 2021, the telescope represents
a giant leap in sophistication over its predeces-
sors. Webb’s primary mirror is a 6.5-meter
(21 feet) diameter reflector composed of 18
hexagonal segments, each coated in gold. As
expected, its first images confirmed that we
are now in a new era of astronomy, one that we
hope will deliver countless discoveries.
The night before the full release, President
Joe Biden and Vice President Kamala Harris
released the first image, the deepest shot of
the universe ever taken to date. Depicting the
galaxy cluster SMACS 0723 in the southern constellation Volans,
the image reveals incredible gravitational lensing of distant proto-
galaxies. The result is the sharpest view of the most distant galaxies
we have yet seen, objects that accreted a few hundred million years
after the Big Bang.
Rather than a pretty picture, the spectrum of a nearby gas giant
exoplanet, WASP-96 b, revealed the most incredible news of that
day — the detection of water vapor in the planet’s atmosphere.
Some 1,150 light-years away lies a world that may well be suitable
atmospherically for living beings.
A longtime favorite of backyard astronomers, galaxy group
Stephan’s Quintet, was another feature. Tidal interactions between
the galaxies were suddenly crystal clear, as if putting on a pair of
glasses from our previous best view.
The Southern Ring Nebula gave us the most distinctive look to
date at a planetary nebula, foreshadowing our Sun’s future. Six or
7 billion years from now, our solar system will dissipate away in a
cloud of cosmic soot that reveals the Southern Ring.
And there was also a stunning portion of a nebula in Carina —
not the Carina Nebula itself, but NGC 3324, a glorious star-forming
region. The image was just jaw dropping, and left us wanting more.
Welcome to a new era of astronomy. The deluge of images and
discoveries will now keep us busy, and excited, for years to come.
Yours truly,
Editor
