Webb Sees Four Images of Same Gravitationally Lensed Quasar

This Webb image shows the RX J1131-1231 galaxy distorted by gravitational lensing into a dim ring; at the top of the ring are three very bright spots with diffraction spikes coming off them, right next to each other; these are copies of a single quasar in the lensed galaxy, duplicated by the gravitational lens; in the center of the ring, the elliptical galaxy doing the lensing appears as a small blue dot.

A quasar called RX J1131-1231 resides approximately 6 billion light-years away in the constellation of Crater. This Webb image shows the RX J1131-1231 galaxy distorted by gravitational lensing into a dim ring; at the top of the ring are three very bright spots with diffraction spikes coming off them, right next to each other; these are copies of a single quasar in the lensed galaxy, duplicated by the gravitational lens; in the center of the ring,...

This Hubble image shows NGC 3810, a spiral galaxy some 50 million light-years away in the constellation of Leo. The color image is composed of infrared, optical and ultraviolet observations from both Hubble’s Advanced Camera for Surveys (ACS) and Wide Field Camera 3 (WFC3) instruments. Nine filters were used to sample various wavelengths. The color results from assigning different hues to each monochromatic image associated with an individual filter.

L1527, shown in this image from Webb’s MIRI instrument, is a molecular cloud that harbors the IRAS 04368+2557 protostar. The more diffuse blue light and the filamentary structures in the image come from organic compounds known as polycyclic aromatic hydrocarbons (PAHs), while the red at the center of this image is an energized, thick layer of gases and dust that surrounds the protostar. The region in between, which shows up in white, is a mixture of PAHs, ionized gas, and other molecules. Image credit: NASA / ESA / CSA / STScI.
