A top-down view of a spiral galaxy, showing its brightly shining centre, its broad spiral arms and the faint halo around its disc, as well as distant galaxies and stars on a dark background. Large blue clouds of gas speckled with small stars and strands of dark dust swirl around the galaxy’s disc. A couple of the background galaxies are large enough that their own swirling spiral arms can be seen.

📷 This NASA/ESA #Hubble image shows spiral galaxy NGC 1309, with its bluish stars, brown gas clouds and white centre, as well as hundreds of distant background galaxies (nearly every smudge, streak and blob is an individual galaxy!)🧪🔭 @stsci.edu @science.esa.int

What's the book about? 🧵

Talk about The Wire, Sopranos, Game of Thrones all you want, but the greatest US television program ever made is Sesame Street. It's not even close. 50+ years of treating kids across class, ethnicity, religion not as mini-consumers...but as citizens with a stake in this world.

My linocut portrait of Henrietta Swan Leavitt is printed in silvery lavender ink on Japanese kozo (or mulberry paper). Behind her is a line showing stellar luminosity (capital L with subscript sun-symbol, a circle with a dot) as a function of time (t). She is printed over constellations in gold (Cepheus, Cassiopeia, Draco, Ursa Minor and Andromeda). ⁠ ⁠

A sprawling, textured field of galaxies scattered across the deep black of space. It is filled with the delicate smudges and glowing cores of galaxies of many shapes, sizes and colors, as well as the bright multi-colored points of stars. The image focuses on a collection of interacting galaxies connected by delicate streams of stars. At top center lies a large elliptical galaxy that is dense and smooth, like a polished stone glowing with golden light. Like delicate spider silk or stretched taffy, these stellar bridges link the large elliptical to the few larger galaxies beneath, evidence of past collisions. All throughout the image, thousands of galaxies gather in clusters or are spread throughout, like glittering gems strewn on a table. Some are sharp-edged and spiral, like coiled ribbons; others round and diffuse, like polished pebbles. Still others are just smudges of various colors against the black of space. The background is peppered with pinpoint stars in reds, yellows, and blues, crisp against the velvet black.

A cosmic tapestry of glowing tan and pink gas clouds with dark dust lanes. In the upper right, the Trifid Nebula resembles a small flower in space. Its soft, pinkish gas petals are surrounded by blue gas, and streaked with dark, finger-like veins of dust that divide it into three parts. It radiates a gentle, misty glow, diffuse and soft like the warmth of breath on a cold hand. To the lower left, the much larger Lagoon Nebula stretches wide like a churning sea of magenta gas, with bright blue, knotted clumps sprinkled throughout where new stars are born. Both nebulae are embedded in a soft tan backdrop of gas that is brighter on the left than on the right, etched with dark tendrils of dust and sprinkled with the pinpricks of millions of stars.

To the lower left is a region filled with the hundreds of golden glittering gems of a distant galaxy cluster. In the foreground, below and right of center, two blue spiral galaxies look like eyes beneath the entangled mass of a triple galaxy merger in the upper right. A few bright blue points of foreground stars pierce the glittering tapestry.

The @nsf-@doescience Rubin Observatory will take so many pictures of supernovae, they'll feel like POP stars 💥🤩

Rubin will observe millions of Type Ia supernovae, allowing scientists to calculate the distances to their galaxies and map our Universe🌌

"Masked security forces captured an opposition leader in the coastal province of New Jersey as regime officials continue their months-long crack-down against pro-democracy elements in the embattled United States. The arrest comes as the regime issued calls for summary detentions without trial."

Exclusive: NSF faces radical shake-up as officials abolish its 37 divisions Changes seen as a response to presidential directives on what research to fund

Exclusive: National Science Foundation staff were told today that the agency’s 37 divisions—across all eight directorates—are being abolished and the number of programs within those divisions will be drastically reduced.

Launched into orbit 35 years ago, Hubble remains one of the most valuable pieces of technology in our search for information about the universe.

Composite shows four Hubble images in quarters. At top left is a crisp view of Mars in shades of orange, blues, and browns. At top right is planetary nebula NGC 2899, which is shaped like a single macaroni noodle, with its central torus appearing semi-transparent and blue and green, and its top and bottom edges in orange. At bottom left is a tiny portion of the Rosette Nebula. Very dark gray material shaped like a triangle takes up the center. At bottom right is barred spiral galaxy NGC 5335 with a milky yellow center that forms a bar surrounded by multiple blue star-filled spiral arms that wrap up counterclockwise.

Hubble has spent 35 years in orbit! 🥳 Celebrate with an array of compelling images recently taken by Hubble: Mars, dramatic views of stellar birth and death, and a magnificent spiral galaxy: bit.ly/4jjsAs7 🔭 🧪

A bright spiral galaxy fills the image with blue spiral arms laced with red-brown dust. Please see the explanation for more detailed information.

A pile of several colorful friendship bracelets. Three are offset to the front, to show prominence, that say “SN 2012Z,” “SIRAH,” and “I ♥️ Science.”

A hand reaching toward a pile of colorful friendship bracelets. On the wrist of the hand there are three red, white, and gold bracelets that say “Astroph,” “UVEX,” and “Rutgers.”

Two hands typing on a laptop. On the screen is a image search engine result showing the Swift Observatory. On the hands are 4 bracelets which say “TDE,” “Neil Gehrels,” “Brad Cenko,” and “Swift.”

🎶 “so make the friendship bracelets, take the moment and taste it” 🎶

I’m at the “Celebrating 20 Years of Swift Discoveries” conference & to make nod to another famous Swift, I made friendship bracelets to share! It’s been a very fun way to introduce myself and bring some joy. :)
