Science Snapshots: Beautiful New Images from James Webb

By

A less dry science post for today!

Part of being a scientist is having a deep, deep appreciation for your field of study. As much as I hate sitting here day after day writing code, fighting with my computer, discussing policy ad nauseam, dealing with bullshit, and/or writing a paper (I HATE WRITING PAPERS), at the end of the day I love the weather. From the peaceful calm of stepping outside on a warm, still morning to the incredible energy that fills every cell of my body when I'm storm chasing, I both love and am humbled by the weather every day.

That extends really to the entire universe. Trees, animals, rocks, planets, stars, galaxies...we love it all here at the Manor. That's why today we simply step back and appreciate the beauty of our universe with the release of images of 19 spiral galaxies taken by the James Webb Space Telescope.

So. Many. Stars. View each image in higher detail here.

The images are part of an excellently-acronymed project, the Physics at High Angular resolution in Nearby GalaxieS (PHANGS) program. 

These images will, in part, be used to look into the cycle of star formation. The use of near-infrared and mid-infrared imagery allows us to see the dust the exists between stars along with stars still in the process of forming. 

A surprise in the images (and it seems like everything Webb sends us is full of such surprises) was the presence of large, spherical shells in the gas and dust. These were possibly caused by exploding stars (the end of their life cycle).

It doesn't end there. Evidence suggests that star formation starts at the center of a spiral galaxy and spreads outwards through the arms. In the images above, newer stars will be located in the red/orange colors at the edges of the galaxy and the blue interiors contain older stars. And pink/red spikes may suggest supermassive black holes or large, compact star clusters.

And that's just scratching the surface. There is so much research and analysis to be done just on these images, not to mention all the previous imagery we've received from Webb. The entire community, not just the PHANGS team, will be working for many years to learn everything we can from these beautiful photos.

But in the meantime, just enjoy the view. I, for one, am so thankful to be alive during a time when we get these beautiful detailed views of our incomprehensible universe.

  Here we are: the shortest day of the year, the longest night. Nature is slowly but surely continuing its cycle of rebirth and we will see brighter days ahead. It's the perfect time to reflect on the past year and consider what kind of light you'd like to bring into your life. A time of hope and renewal. I wish you all a happy Solstice!

OPEN POST: Manor Music Monday With Barbara Cartland!

Are you off work yet? Are you ready to throw a swingin' party? That means making party music mixes, right? And, yes, you must throw in a WTF song in the middle of the mix just to mess with everyone. For example, say you're throwing a New Years Eve party with a bunch of cooler-than-cool jazz or house music tracks; in the middle if it, throw in this song . I guarantee everyone will squeal with delight. In fact, throwing that song into any mix is always a good move.  Want more ideas for WTF songs to drop into your mixes? DJ Li'l Scratch has got you covered. But first, let's pause for a moment. This is important. Why? Because this is the definition of beauty: The face: like a pale, English Cream Custard (which is just a bit overcooked). The jewelry: made from the finest diamonelles money can buy. The eyes: with their exquisite baby tarantula eyelashes (the eye shadow is their after-birth). I'm overcome, I can barely breathe. And, no, this is not RichBitch. She is, of c...

OPEN POST: Merii Kurisumasu めりーくりすます! Or Christmas In Japan Is For Couples!

Christmas is celebrated differently in Japan, yet much of it is recognizable. We see beautiful lights, Santas, and  decorated trees, and it is a time for getting together. But it diverges there because Christmas in Japan is for couples.  They exchange gifts and cozy up for romance. Though American food is preferred, KFC is  preferred ; it can get expensive, so they will have tasty Japanese romantic dinners or something delicious and homecooked.  It is common to see couples holding hands flushed with love and happiness. It is like Valentine's Day except on Decemeber 25th. Only about 2% of the Japanese people call themselves Christians, so it would make sense to carve out their own traditions and make this holiday something unique to them and reflects their culture.  Christmas Eve is for  kurisumasu ke—ki , a sweet sponge cake with filling, but the next day is for dressing up, making fancy dinner reservations, and staring into the eyes of your "ride or d...
