Hyperluminous infrared galaxies are the rarest and most extreme star-forming systems and found only in the distant Universe. Stellar, cold-gas and ionized-gas emission distributions of the rare HyLIRG Einstein ring, PJ0116-24. Image credit: Liu et al., doi: 10.1038/s41550-024-02296-7. “Hyperluminous infrared galaxies (HyLIRGs) are incredibly bright galaxies, lit up by the extremely rapid star formation within them,” said Dr. Daizhong Liu of the...

This Hubble image shows NGC 5238, a dwarf irregular galaxy located 14.5 million light-years away in the constellation Canes Venatici. The color image is made up of observations from Hubble’s Advanced Camera for Surveys (ACS) in the near-infrared and optical parts of the spectrum. Two filters were used to sample various wavelengths. The color results from assigning different hues to each monochromatic image associated with an individual filter. Image credit: NASA / ESA / Hubble / F. Annibali.

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.
