Webb's First Year of Science

In its first year of science operations, the James Webb Space Telescope exceeded astronomers’ expectations and wowed the world with stunning imagery.

This horizontal image has layers of semi-opaque rusty red colored gas and dust that starts at the bottom right and goes toward the top left. There are three prominent pillars rising toward the top left. The left pillar is the largest and widest. The peaks of the second and third pillars are set off in darker shades of brown and have red outlines.

Call for Self-Nominations for the Roman Community Survey Committees

Self-nominations for serving on one of the three committees which will define the Roman Space Telescope's Core Community Surveys are due by August 14, 2023.

Hubble’s ULLYSES Program: Improved and New Data Sets

New spectra for massive stars in the LMC, SMC, & low-metallicity galaxies; a new epoch for T Tauri stars; and updated products for 339 ULLYSES stars.

The acronym ULLYSES appears in large white letters with rainbow lettering at the center over a black background speckled with multi-colored, tiny stars.

Webb Spotlights Gravitational Arcs in 'El Gordo' Galaxy Cluster

August 02, 2023

$A black background is scattered with hundreds of small galaxies of different shapes, ranging in color from white to yellow to red. Some galaxies are distorted, appearing to be stretched out or mirror imaged. Near the center, a particularly long and thin line stretches from ten o’clock to four o’clock. At upper right, a red swoosh extends about three-quarters of the way around a pair of galaxies. A handful of foreground stars display eight diffraction spikes.$

Webb Snaps Highly Detailed Infrared Image of Actively Forming Stars

July 26, 2023

$At the center is a thin horizontal orange cloud known as Herbig-Haro 46/47 that is uneven with rounded ends, and tilted from bottom left to top right. It takes up about two-thirds of the length of this angle, but is thin at the opposite angle. At its center is a red-and-pink star with prominent, eight-pointed diffraction spikes. It has a central yellow-white blob. The orange lobe to the left is fatter. Just off the edge is a tiny red arc that curves in the opposite direction. The right lobe is thinner, and ends in a smaller orange semi-circle that has a faint purple outline. Just off the edge of this lobe is a slightly smaller orange sponge-like blob. A thin, undulating blue line runs from the central stars through the right lobe. A delicate, semi-transparent blue cloud known as a nebula drifts toward the top of the image and peters out toward the left of the frame, but toward the right and bottom, it ends in a soft ridge set off in a translucent orange. The background is filled with stars and galaxies.$
