Lise Meitner - Wikipedia

Today's reading begins with Lise Meitner, who co-discovered nuclear fission (she wrote the paper!) and was in general an INCREDIBLE trailblazing scientist.

Except, as a Jew, she had to flee Nazi Germany to Sweden and lost her professorship in Berlin. The men she worked with got the prize instead 🧪🔭

Sent my collaborators a JWST proposal idea and it’s either absolutely 🤪 or completely 🧐🤩🤓💡

On a side note I now have Dizzee Rascal's song Bonkers stuck in my head.

🔭 I love plotting a new JWST stellar catalogues and
colour magnitude diagram for the first time. Seeing new stars and populations. They are just so clean and beautiful. All the features you can see, from stars I have just detected for the first time ever 😊 It's a rather giddy feeling.

That is good news indeed.

I want to rage at narrative cv’s. Why require 2000 words when you could have a nice concise list version instead. And who wants to review that instead.

Webb investigates complex heart of a cosmic butterfly The NASA/ESA/CSA James Webb Space Telescope has revealed new details in the core of the Butterfly Nebula, NGC 6302. From the dense, dusty torus that surrounds the star hidden at the centre of the nebu...

MIRI on JWST keep delivering. We have looked into the body of the butterfly nebular and seen such fantastic structures.
The death of stars like the sun is alot more dynamic than you could imagine.

Very happy to be a member of both the science and MIRI teams.

Does anyone here / at @rasjournals.bsky.social know then the MNRAS journal went fully electronic?

a television screen shows a man reading a book titled the justice league encyclopedia of space Alt: HOLLY, the AI from Red Dwarf, is reading a book with a name very similar to the Starbug II installation success messages.

Running @conornally.bsky.social STARBUGII code for JWST PSF photometry.

Seen this in the installation messages: “Downloading The Junior Colour Encyclopedia of Space” 😂

A spiral staircase in a lovely concrete carpark. Out the top of the stair you can see the sky, Edinburgh Castle, and the Red Arrows.

Haha! It worked!

I scoped out the angle this morning and figured I’d be very lucky to pull it off, but it was surely worth a try, eh?

How gorgeous is that?

An area of deep space with thousands of galaxies in various shapes and sizes on a black background. Most are circles or ovals, with a few spirals. More distant galaxies are smaller, down to being mere dots, while closer galaxies are larger and some appear to be glowing. Red and orange galaxies contain more dust or more stellar activity.

For the latest image of the month, the NASA/ESA/CSA James Webb Space Telescope revisits the iconic Hubble Ultra Deep Field.

The deep observations reveal more than 2500 sources sparkling in this tiny patch of sky ✨

But why just jwst and ssds and not hst or any other facilities. It seems a strange one to me. @robertmassey.bsky.social did you look into this strange stat any further?

Stats in a survey 10% of women while 20% of men use JWST and SDSS.

Reading the RAS demographic survey for 2023. 🔭
Rather surprised that there is some major difference in JWST usage between genders give the dual anonymous proposal proces.

Dusty rings around four carbon-rich WR binaries from JWST/MIRI. Top left: WR48a, top right: WR112, bottom left: WR 125, and bottom right: WR 137 blue = 7.7 um green = 15 um red = 21 um

After we found the dust survived in this harsh environment, I led a team to ask the question: Is it long-lived for all of the harsh environments? So, we proposed for JWST observations in Cycle 2, and finally had observations taken last summer. Here are the four systems we observed

Diagram comparing the fields of view of LSST and JPCam. LSST in the upper half, showing a 3.5 degree field of view covered with 189 4k×4k science CCDs organized in 21 3x3 "rafts". JPCam in the bottom half, with a 3 degree diameter field of view filled with 14 9.2k×9.2k science CCDs. The Moon has been added to both diagrams to compare the field of view with its angular diameter.

I guess it's a good time to post a comparison between the field of view of @vrubinobs.bsky.social and the instrument I work with: JPCam at @cefca-oaj.bsky.social

Ours is at a 2.5 m telescope vs. their 8.4 m, and we have 14 9.2k×9.2k science CCDs vs. their 189 4k×4k organized in 21 "rafts" of 3x3.

Happy to announce that the line-detector.oca.eu website is now online!
It allows the user to select the stellar type, [M/H], λ- range, and resolving power and the page returns:
-purity of the line and minimum S/N required to detect it.
-interactive plot to identify the lines in the spectra

Drowning Doesn’t Look Like Drowning Drowning is not the violent, splashing call for help that most people expect.

Thanks for the reminder @janemunday.bsky.social. Every summer, I repost this article DROWNING DOES NOT LOOK LIKE DROWNING. To date, I know of FOUR kids who were saved after someone who'd clicked on the link learnt how to spot actual drowning. Take time to read and pass on.

The Nearby Evolved Stars Survey (NESS) V: properties of volume-limited samples of Galactic evolved stars We provide a meta-study of the statistical and individual properties of two volume-complete sets of evolved stars in the Solar Neighbourhood: (1) 852 stars from the Nearby Evolved Stars Survey (NESS),...

Paper day: Want to know the properties of ALL the Nearby (300 pc) evolved stars - we have just the catalogue for you!

FYI: There are 852 evolved stars close to us.

The final set of JWST MIRI EC observations are scheduled for tomorrow! Looking forward to completing the picture of Cen A.

A black and white (sort of sepia-toned, actually) photo of Helen Quinn standing at a blackboard. She is wearing a light colored cardigan sweater with a collared shirt or blouse underneath. Her left hand is holding a piece of chalk to the blackboard, but her head is turned and looking at the camera. She has short hair, dark eyes, and is smiling. The blackboard is covered in messy diagrams of what I assume are drawings of different possible potentials for the axion field.

Physicist Helen Quinn was born #OTD in 1943. She is best known for Peccei-Quinn theory, a proposed explanation of the Strong CP problem of quantum chromodynamics. It implies the existence of a very light particle – the axion – which is also a dark matter candidate. 🧪 🔭 👩‍🔬

Brilliant news 🙌

Yes. I'm going to love this. The small person will do to!

I have just arrived back in Japan, bringing home the 1:20 scale model of the JAXA Hayabusa2 spacecraft that has been on display at the London Science Museum.

Five customs officials examined the model.

There was nothing amiss with the paperwork. They just wanted to see the model 😂

Red all the way.
