Sirius: the coruscating jewel of the northern winter night sky 😍

Was in a seminar this morning with my old ESA colleague, Manfred Warhaut, former head of the Mission Operations Department at ESOC.

Which gives me the excuse to post this iconic picture we're both in from 20 January 2014, at the moment when Rosetta woke from its 2.5 year long deep space hibernation ahead of its rendezvous with Comet 67P/Churyumov-Gerasimenko later that year.

Goosebumps to this day, almost a decade later 🙇‍♂️

Thanks for all the lovely attention & comments on our NASA/ESA/CSA #JWST image of HH212 yesterday, & welcome to everyone newly following.

On this wet, windy Sunday afternoon, I thought I'd combine all four of our recently-released JWST Cycle 1 star formation images into one post & mini-thread.

Namely the short- & long-wavelength mosaics of the inner Orion Nebula & Trapezium Cluster, and the protostellar flows HH211 & HH212.

A wide-field image of the inner Orion Nebula & Trapezium Cluster as seen at shorter near-infrared wavelengths (1-2.1 microns) by JWST. The image is predominantly blue due to ionised hydrogen, but there are regions of brown due to dust absorption and bright red due to emission from shocked & fluorescent molecular hydrogen. There are thousands of stars, brown dwarfs, & planetary-mass objects strewn across the region, centred on the Trapezium OB stars.
A wide-field image of the inner Orion Nebula & Trapezium Cluster as seen at slightly longer near-infrared wavelengths (2.7-5 microns) by JWST. The image is predominantly purple due to ionised hydrogen & green due to polycyclic aromatic hydrocarbons, but there are regions of brown around the edges due to dust absorption and bright red due to emission from shocked & fluorescent molecular hydrogen. There are thousands of stars, brown dwarfs, & planetary-mass objects strewn across the region, centred on the Trapezium OB stars.
The protostellar outflow HH211 near the IC348 cluster in Perseus as imaged with JWST in the near-infrared (2-5 microns). The linear jet is purple and red due to shocked molecular hydrogen emission, with contributions also from carbon monoxide. There is some green reflection nebulosity along the flanks of the outflow, while the driving protostar is invisible at the centre. There are a few stars and some other molecular hydrogen emission strewn across the dark background.
The symmetric protostellar jet & outflow HH212 to the north-north-east of the Horsehead Nebula near the Belt of Orion as imaged in the near-infrared (2.1-5 microns) with JWST. The linear outflow comprises a series of knots and bowshocks on either side of the invisible driving protostar & is dominated by red/purple shocked molecular hydrogen emission. It is seen against a green nebular background of polycyclic aromatic hydrocarbon emission, & there are stars & many galaxies strewn across the background. Another pair of protostars with their own nebulae are seen near the lower end of the image.

Morning.

Here it is, several thousand years in the making: the protostellar jet HH212 as seen in the infrared by #JWST.

We discovered this jet in 1993, glowing in the light of shocked molecular hydrogen at 2.12 microns, as gas emerges symmetrically at about 100 km/s from the two poles of a young protostar not far from the Horsehead Nebula in Orion.

Our new JWST image spans six wavelengths & is ten times sharper than any previous infrared image.

Well, isn’t that lovely: our JWST image of the inner Orion Nebula & Trapezium Cluster is today’s Astronomy Picture of the Day 🖖🙂🤘

Thanks to everyone who’s sharing the images & don’t forget that you can download them at full resolution under a CC BY-SA licence via the link in the next toot 👇

As promised, some more #JWST loveliness today.

Our paper on the HH211 protostellar outflow, with Tom Ray of Dublin as first author, is in this week’s print edition of Nature 👍

And … we have the front cover, the first time a JWST science image has featured there, we think 🎉🙇‍♂️

I made this new version of the image in my Reykjavík hotel room last week & while travelling home 😬

Quite proud of it – enjoy 🖖🙂🤘

It's paper time!

The first results from my #JWST time, in a project shared with Tom Ray et al. from the MIRI consortium, a study of the extremely young protostellar outflow, HH211, in Perseus, published in advance form in Nature today.

Here's the headline image, a composite of three of the NIRCam filters we used.
