@mast-news.bsky.social and is at Villanova @villanova teaching undergrads from nearby universities. They got a quick overview of NASA mission data available ilat MAST, astroquery, TESS and FITS/ASDF files.

Students and a screen saying FITS structure.

Went to see Ceilidh the musical last night. Such fun for those who like to participate in the shows they attend.

Thanks for bringing this show to Baltimore, Noisemaker. www.noisemaker.org.uk/ceilidh-1

For the morning crowd, here are all the observations stored in the Mikulski Archive for Space Telescopes. A visual created by Julie Imig, one of our amazing astronomical data scientists. Follow the link below for more colors and even a movie.

MAST's view of the sky, labeled with well known astronomy surveys. it is blue and white where there are many observations, especially around the south ecliptic cap and along the milky wy where there are many stars.

Ever wondered what the "MAST Sky" looks like, from our ~6 PB of data spanning 3 decades...check this out! spacetelescope.github.io/mast-blog/ma...

Really fun project led by the very talented Julie Imig at MAST, showing mission coverage sky-projected! They make VERY good video backgrounds, btw. 🔭

MAST background in "standard" sky projection, in hues of blue. Lighter blue areas mark lots of observations, while darker areas are less. Numerous patterns are visible, like the continuous viewing zones as ovals in the lower-left and upper right, patterns from overlapping TESS FFIs, or the Kepler footprint shapes stamped along the ecliptic and in the original Kepler field in the upper-right.

A grid of 16 images, 4x4, showing the sky background only for specific missions to get a sense of where in the sky and how much of it each mission observed to at least some depth.

New 🪐 around white dwarfs (WD) paper by yours truly! My collaboration had a Cycle 1 #JWST program to look at WDs accreting dust from planetary systems. We looked at four targets and found extra light at 21 microns for two of them! #astrosci #exoplanets 🔭🧪https://arxiv.org/abs/2506.21224 (1/n)

Metal Polluted White Dwarfs with 21 μm IR excesses from JWST/MIRI: Planets or Dust?

White dwarfs with metal pollution are caused by the accretion of rocky dust from tidally disrupted minor bodies and are signposts for planetary systems. These minor bodies are perturbed by planets tha...

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.

JWST is observing this stellar remnant in order to see if the nearby red smudge is a planet. We know the white dwarf has high proper motion and will move a several pixels, will the red smudge also move those few pixels? We will find out when they bring the data down.
