Clumpy galaxies dominate the early universe, yet their local counterparts are hard to find. A new machine‑learning approach learns to spot these hidden clumps and opens the door to studying them in far greater detail.
Space is full of unusual and (sometimes) quite powerful phenomena that cause light to behave in unexpected ways. Maser systems are one of these phenomena. The MeerKAT Radio Telescope recently detected the most luminous and distant hydroxyl (or OH) maser system – so intense it crossed the threshold from “mega-maser” to “giga-maser”. Discover why this system is so remarkable in this bite!
So we have a pretty good idea of how old the Universe is right? Well according to JWST data, maybe not? Rest assured, today’s bite gets to the bottom of the debate.
Take a walk down memory lane with I Zwicky 18, which could be the key to unlocking the secrets of the early universe.
The “timing argument” overestimates the total mass of the local group by oversimplifying it to a two body problem, a new study explore how the complex merger history of objects in the group affect its mass estimates.
Something is missing in the middle. In JWST JADES galaxies, young clumps drop out in the inner regions, while clump structure shifts from the outskirts to the center.
