#PorSiTeLoPerdiste - 🔭 ¡Webb desvela pistas sobre el origen de 3I/ATLAS!
Cuando el cometa interestelar 3I/ATLAS comenzó a alejarse del Sol en diciembre de 2025 ☄️ los astrónomos aprovecharon para analizar su composición química con el instrumento #NIRSpec de Webb.
Gracias a estas observaciones, han podido profundizar en el entorno en el que se formó. 1/3 👇
🆕 Webb has found clues to the ancient origins of 3I/ATLAS!
As the interstellar comet 3I/ATLAS began moving away from the Sun in December 2025 ☄️ astronomers took the opportunity to study its chemical makeup with the #NIRSpec instrument on Webb. This allowed them to understand the environment in which the comet formed. 1/3

Don’t miss the latest #SpaceSparks — NGC 5134!
This nearby galaxy was captured by #MIRI and #NIRSpec for our latest ESA/Webb Picture of the Month, revealing its stellar lifecycle ⭐🔄

🆕 Webb has mapped the upper atmosphere of Uranus!
Using the #NIRSpec on Webb, astronomers collected data on the ionosphere – the upper atmosphere of Uranus, where it becomes ionised and interacts strongly with the planet’s magnetic field. 1/3

🆕 Webb has been watching a lava world! 🌋
The emission spectrum captured by #NIRSpec shows the brightness of different wavelengths of light coming from the ultra-hot super-Earth exoplanet, TOI-561 b, during a secondary eclipse. The data suggest the planet is not a bare rock, but surrounded by a thick, volatile-rich atmosphere. 1/2
Webb’s #NIRSpec was used to analyse the galaxy’s spectrum and estimate the mass of the accreting supermassive black hole at its centre. It’s big – unusually big for a galaxy of CANUCS-LRD-z8.6’s size. 2/3
We can’t yet rule out an atmosphere, since many data points fit either scenario – but Webb will make more observations and help researchers refine their atmospheric readings!

A team of astronomers using Webb’s #NIRSpec identified powerful hydrogen emission from GS-z13-1. This caught them by surprise – it was far stronger than was thought possible at this stage, when the Universe was filled with a thick fog! 😶🌫️ 2/4
