Same here! 8 years at STScI!

Great job. Amazing Poster!

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 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.

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. 🔭

That is where all the planets with the best vacation spots are hiding.

Think of what we have learned and have yet to learn from investing in these missions and making their data open and available to everyone.

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...

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)

The logo for the Hubble Advanced Spectral Products, or HASP. White lettering with a rainbow border below. To the right is a set of stylized spectra ranging from violet to red that are in the process of "hooking" together. A hasp is a latching mechanism, which is similar to what HASP does--link different gratings from HST spectroscopy together.

Like #Hubble spectra, but it's hard to access? My working group @stsci.edu launched the Hubble Advanced Spectral Products, joining COS and STIS spectra across different modes and instruments for every HST program for the first time 🧪🔭https://archive.stsci.edu/missions-and-data/hst/hasp (1/4)

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.

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. 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.

Hello from #NoKings Towson!

TOMORROW! We're just a day away from NO KINGS DAY in Patterson Park!

Here are Saturday's schedule and our march route.

#aas246 MAST @mast-news.bsky.social was saved from the evil plans of Dr. Nefarious by the team of scientists attending the AAS. Thank you to those who attended this escape-room-themed MAST workshop at the AAS, had a little fun, and learned a bit about our archive.

And now it's the other white dwarf planet candidate's turn!

JWST miri image of a white dwarf star and a dimmer source next to it.

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.

Smile pretty little white dwarf star, JWST is taking your picture.

#astronomy #AAS246
Astronomers, If you are coming to the summer AAS in Alaska, come a day early and join us for a fun MAST workshop.

Join MAST at the summer AAS #aas246 and learn about data discovery and analysis in the cloud. Plus have some fun along the way by defeating Dr. nefarious before he deletes all of the MAST data!!

I hope to see you in Anchorage.

My daughter also thinks the one that hugs the city line on the north east looks like a curled up fox.

Baltimore County map with new district lines and a blue and pink salamander drawn over one of them.

Baltimore County is in the process of redistricting to gain 2 new districts.
Interestingly enough, One of the proposed districts looks suspiciously like a Salamander, as shown by my daughter's handiwork.

MAST at AAS 246

Join us at the summer AAS meeting for a MAST workshop to help defeat Dr. Nefarious in a short data challenge.

The workshop is on Saturday and will show you how to make use of MAST data and compute in the AWS cloud to do astronomy. archive.stsci.edu/contents/new...

I hope to see you there!

Have you tried a VO registry search?

Happy 35th Birthday Hubble!

What a great time to remember how a small investment in science can inspire a generation.

BREAKING NEWS: Our Umani herd just got a little bit bigger! At 9am this morning — after a pregnancy that kept us all waiting — Zongoloni’s baby was finally ready to make his debut.

Zongoloni gave birth amidst her human-elephant family, safely delivering a beautiful little boy.

I wrote a research note about the recent publication of the MIRI/LRS spectrum of K2-18b. The authors had claimed the detection of potential signs of life. I find the data to be consistent with a flat line 🔭🧪

The Trump-Supreme Court battle is not really the crisis.

The crisis is here now. Trump is enacting an insidious coordinated attack on our institutions of democratic accountability, designed to crater democracy before next fall.
