1️⃣ 2️⃣ The series of #Nature papers also reports the same transmission spectrum with 2 other instruments on board #JWST: #NIRISS in the paper led by @afeinstein20 et al. and #NIRCam in the paper led by @eahrer et al.
The spectra revealed again a lot of features with a higher resolution than #NIRSpec / PRISM.

What is (really) super impressive is the fact the 3 instruments / 4 modes give nearly the same signal, with basically no systematic at all.

4️⃣ We knew that its #atmosphere was revealing water (H2O), carbon dioxide (CO2) as well as sodium (Na) and potassium (K). It was therefore a very good target to #test the instrumental capabilities of #JWST in the near infrared (#NIR).

The objective of the team was therefore to observe that unique object with all instrumental modes of #JWST in the #NIR, to learn about the instrument and understand its limitations (if any). They used #NIRSpec (in 2 different modes), #NIRCAM, and #NIRISS.

Each instrument is using a different broadband filter in the LMC here.

#NIRcam: 2 micron
#NIRSpec: 1.1 micron
#NIRISS: 1.5 micron
#MIRI: 7.7 micron

#JWST has finished alignment and has released the first fully focused images from all instruments!! 🤩🤩🤩 Commissioning now continues, shifting focus to calibrating #NIRCam, #MIRI, #NIRISS and #NIRSpec. #Astronomy #Space https://blogs.nasa.gov/webb/2022/04/28/nasas-webb-in-full-focus-ready-for-instrument-commissioning/
