Here's a clearer version of the image caption: Colored map of the PJ308-21 system showing gas emissions: - Hydrogen: Red and blue - Oxygen: Green The central quasar's light has been masked out. Color variations in the quasar's host galaxy and its companions indicate different gas properties in each region.

Cosmic Growth Spurt: Supermassive Black Hole Mimics Star Formation

NASA's Webb telescope captures a stunning image of the Serpens Nebula, revealing a cluster of baby stars in the top left corner. These stars are still forming and shooting out powerful jets of gas in a surprising, aligned pattern. Unlike some nebulae, Serpens doesn't create its own light. Instead, it glows by reflecting light from nearby stars.

Webb Telescope Sees “Baby Stars” Blasting Jets in Perfect Alignment

A galaxy suddenly became much brighter in late 2019. This reveals a giant black hole at its center that's woken up and started feeding on surrounding gas, making the whole galaxy light up. This is the first time scientists have observed this awakening happen.

This illustration depicts two quasars in the process of merging. Using both the Gemini North telescope, one half of the International Gemini Observatory, which is supported in part by the U.S. National Science Foundation and operated by NSF NOIRLab, and the Subaru Telescope, a team of astronomers have discovered a pair of merging quasars seen only 900 million years after the Big Bang. Not only is this the most distant pair of merging quasars ever found, but also the first confirmed pair found in the period of the Universe known as Cosmic Dawn.

Watery planets orbiting dead stars may be good candidates for studying life — if they can survive long enough

An international team of astronomers has utilized NASA's James Webb Space Telescope to investigate the disk of gas and dust surrounding a young, low-mass star called ISO-ChaI 147. Their findings, depicted in this artist's impression, show the most diverse and abundant collection of carbon-containing molecules ever observed in a planet-forming disk around a star.

Panels a, b, and c each show stereographic image pairs of the asteroid Dinkinesh taken by the NASA Lucy Spacecraft’s L’LORRI Instrument in the minutes around closest approach on Nov. 1, 2023. The yellow and rose dots indicate the trough and ridge features, respectively. These images have been sharpened and processed to enhance contrast. Panel d shows a side view of Dinkinesh and its satellite Selam taken a few minutes after closest approach. Credit: NASA/SwRI/Johns Hopkins APL/NOIRLab.
