In a galaxy hanging out in the early Universe less than 1.5 billion years after the Big Bang, the James Webb Space Telescope has made an astonishing detection.
From light that traveled for over 12 billion years from a galaxy known as SPT0418-47, astronomers teased out the spectral signal of complex molecules – the polycyclic aromatic hydrocarbons (PAHs) that make up some of the dust grains in the clouds that drift between the stars, soaking up the light and re-emitting it at infrared wavelengths.
This dust indicates a high rate of star formation, which isn't unexpected for a galaxy of this early Universe epoch. But the dust is not uniformly distributed, and that shows that this star formation can be mapped to different locations within the galaxy, according to a team led by astronomer Justin Spilker of Texas A&M University.
