What a difference a large mirror makes!

Here are two images of the same object, Herbig-Haro 46/47. HH 46/47 is a pair of jets launched by young stars.

They are taken at similar wavelengths of infrared light. The difference? #Spitzer's mirror was 85 cm (33 inches) in diameter, about the size of a hula-hoop. #JWST's mirror is 6.6 meters (21.7 feet) in diameter, the height of a two-story building.

Die ersten negativen Effekte sind in den jetzigen Schülergenerationen schon sichtbar und werden kaum noch zu korrigieren sein.

Ich bleibe bei meinen Überzeugung:

1. #Weizenbaum hatte Recht.

2. #Spitzer hat Recht.

3. Digitale Medien haben in Kitas (IMO auch Grundschulen) nicht nur nichts zu suchen, sie sind *dort* sogar schädlich.

Check out this new visualization from Universe of Learning — Stephan's Quintet: A Multi-wavelength Exploration.

Based on data from Hubble, Spitzer, Chandra, and JWST, take a 3D journey through the galaxies in Stephan's Quintet. See the stretched-out features from the gravitational interactions between the galaxies, the shocks created as they run into one another, and the secret supermassive black hole obscured by dust.

Thomas gave a really nice talk highlighting the PAHs and grain size distribution as a result of AGN ionization in #NGC7469! To learn more about this system, check out our papers on MIR AGN spectrum (Armus+22), highly ionized outflow (U+22), SF regions in the ring (Bohn+22), and ISM conditions (Bianchin+22, in prep). The spectral resolution improvement of #JWST #MIRI over #Spitzer is jaw-dropping!

The article also features a beautiful image of Orion’s sword made from Spitzer, Herschel and WISE data by the inestimable Robert Hurt. This region is also known as the integral shaped filament and contains the Orion Nebula Cluster. Thanks to Pat Brennan for writing this great article. The goofy quotes are my responsibility. The papers on the protostar outbursts can be found at https://ui.adsabs.harvard.edu/abs/2015ApJ...800L...5S/abstract and https://ui.adsabs.harvard.edu/abs/2022ApJ...924L..23Z/abstract. #protostars, #orion, #spitzer, #herschel, #outbursts, #eruptions.

Flares from the #Supermassive #Binary #BlackHole OJ 287 put constraint on the “No Hair Theorem” | NASA’s infra-red #observatory #Spitzer has recently observed the flare from gigantic binary black hole system OJ 287, within the estimated time interval predicted by the model developed by #astrophysicists This observation has tested different aspects of General #relativity the “No-hair theorem”, and proved that OJ 287 is indeed a source of #infrared Gravitational..

3️⃣ First of all, why is WASP-39 b so particular to be the target of FIVE #Nature papers ?

Well, this #planet is a transiting hot jupiter, as we know hundreds of them. It's a giant #planet orbiting with an orbital period of 4 days.

Its atmosphere was already well known as observed by the #Hubble #space #telescope (with 2 different instruments), the #Spitzer space telescope, and the 8.2m #ESO #VLT telescope in #Chile.

Below is the transmission spectrum of WASP-39b that we knew before #JWST.

Finally, as part of NASA’s Cosmic Origins Program Analysis Group (COPAG), I participated in a study of the past and future of panchromatic astronomy from space. This beautiful document from the SAG-10 group (SAG = science analysis group) overviews the Great Observatories program and makes recommendations for the future. It was published before the ASTRO2020 decadal review, and I hope it had some impact. https://arxiv.org/abs/2104.00023. #NASA #Spitzer #Chandra #Hubble

This is probably the most humbling & awe-inspiring image of the #Universe I know.

It's an infrared image by the #Spitzer #Space #telescope, as wide as the full moon.

The dots aren't stars.
They're galaxies.
Each dot is 100s of Billions of stars.(1/n)
