these webb/hubble images are truly incredible. the fact that we can see the universe in different wavelengths of light and spot so many unseen details is mind-blowing 🌌

Two observations of a portion of the galaxy NGC 628 are split diagonally, with Webb’s observations at top left and Hubble’s at bottom right. The galaxy’s core is roughly centered and the galaxy’s arms appear to rotate counterclockwise. The spiraling filamentary structure looks somewhat like a cross section of a nautilus shell. In Webb’s image, the spiny spiral arms are composed of many filaments in shades of orange, with prominent dark gray or black “bubbles,” and there is a blue haze near the core. In Hubble’s image, the spiral arms are a mix of bright blue star clusters, pink star forming areas and dark brown dust lanes, and the core is a pale yellow.

Two observations of the galaxy NGC 1300 are split diagonally, with Webb’s observations at top left and Hubble’s at bottom right. The galaxy’s core is centered, connected to a prominent diagonal bar structure. The galaxy’s two distinct spiral arms begin at the end of the bar and rotate counterclockwise. Together, the arm and bars form a backward S shape. In Webb’s image, the bar and spiral arms are composed of many filaments in shades of orange, and are anchored by its central region, which is circular and light yellow. In Hubble’s image, the spiral arms are a mix of bright blue star cluster and dark brown dust lanes, and the bar and core are a pale yellow.

Two observations of the galaxy NGC 1512 are split diagonally, with Webb’s observations at top left and Hubble’s at bottom right. The galaxy’s core is centered and circular, with two prominent dust lanes crossing the large diagonal bar structure appearing toward the top left and bottom right. The central bar is blue at top, looking like a gap until a closer examination shows it feeds a larger, oval shape that looks braided with many spiral arms. In Webb’s image, the spiral arms are composed of many filaments in shades of orange. In Hubble’s image the bar is a light pinkish-brown and the spiral arms are a mix of bright blue star clusters and dark brown dust lanes.

Two observations of the galaxy NGC 3351 are split diagonally, with Hubble’s observations at top left and Webb’s at bottom right. The galaxy’s core is centered and the galaxy’s arms rotate clockwise and form a distinct outer ring. In Hubble’s image, the galaxy’s roughly horizontal bar structure is a pale yellow and the spiral arms are a mix of bright blue star clusters and dark brown dust lanes that form half of the large circular ring. In Webb’s image, the spiral arms form the other half of the large ring, which is made of many filaments in shades of orange. They are anchored by its central region, a hazy blue bar, connected to the central core. The core has a small orange oval around a more circular light yellow oval, with a blue dot at its center.

Hoo boy, I bet you could use a distraction today!

So how about an intense JWST image of a pair of colossal stars whizzing past each other and blasting out wave after wave of dusty shells, expanding away at a soul-freezing NINE MILLION KPH?!

Two colossal stars send out waves of dust in an amazing JWST image

WR 140 is a terrifying star system, but it sure is beautiful. Also, announcing a new rate for the newsletter.

What on earth would we ask a sperm whale, if it was made possible to ask it?

The first photo of the Andromeda galaxy was taken by astronomer Isaac Roberts #OTD in 1888.

The image, captured with his 20" reflector, revealed a clear spiral structure. But scientists at the time thought M31 was a nebula, a gas cloud in our galaxy. 🧪 🔭

Black and white photo of the Andromeda Galaxy, a spiral galaxy with a strong central bulge. Two smaller satellite galaxies float nearby, and the foreground is dotted with stars.

Labour's approach to fire safety revealed: the same stuff, but a bit more of it

Yesterday's announcement on building safety remediation and the evacuation of residents with disabilities stuck closely to the models established by the last administration. Strap in for a long post.
