An HR diagram from the Hipparcos-Tycho catalog. The stars in the HALO-TESS sample are color-coded by the number of available TESS sectors, with their sizes indicating their apparent V-band magnitudes. The y-axis plots absolute V magnitude ranging from 6 to -9, the x-axis plots B-V color ranging from -0.5 to 2.0. A majority of the HALO-TESS targets land from absolute V magnitudes of 2.5 to -6 and B-V colors from -0.5 to 0.25, although a few targets populate unique areas of parameter space.

New HLSP: HALO-TESS provides custom light curves for 98 saturated stars in TESS Full Frame Images. The team presents 411 light curves from Sectors 1-93, of which 77 are identified as variables! archive.stsci.edu/hlsp/halo-tess

Sky projected plot of the Sectors 83-97 footprints on the sky. Each footprint is shaded a different color to stand out compared to others. Right ascension is along the x-axis and declination is along the y-axis. The biggest gaps in coverage occur approximately between 0 and +50 degrees declination, and along right ascension 23 to 5 hours. The x-axis spans from 24 hours to 0 hours (a reversed axis) and the y-axis spans from approximately -80 to + 80 degrees.

A histogram showing the number of targets per 0.25 magnitude bin from three different categories: two-minute targets (in dark blue), FFI-included targets (in light blue) and FFI field star targets (in red). The two-minute targets are primarily between TESS magnitude 8-12 and the maximum bin count is approximately 1000. The FFI-include targets have a more strongly peaked distribution centered on TESS magnitude 11 and at the maximum bin count is approximately 6500. The FFI field star targets also follow a strongly-peaked distribution centered at TESS magnitude 12.5 and have a maximum bin count size of almost 16000.

Screenshot showing the title, authors, and abstract. Title is "The Impact of the MAST Data Archive". The abstract is "The Barbara A. Mikulski Archive for Space Telescopes (MAST) hosts science-ready data products from over twenty NASA missions, plus community-contributed data collections, and other select surveys. The data support forefront research in the ultraviolet, optical, and near-infrared wavelength bands. We have constructed bibliographies for each mission from publications in nearly 40 professional journals, and have identified more than 37,000 refereed articles where investigators made a science usage of data hosted in MAST. The publication rate over the last 50 years shows that most MAST missions have had very high productivity during their in-service lifetimes, and have remained so for years or decades afterward. Annual citations to these publications, a measure of impact on research, are robust for most missions, with citations that grow over more than a decade. Most of the citations come from about 10% of articles within each mission. We examined the bibliographies of the active missions HST and JWST in greater detail. For HST the rate of archival publications exceeded those authored by the original observing teams within a decade of launch, and is now more than 3 times higher. Early indications hint that JWST archival articles could dominate the publication rate even sooner. The production of articles resulting from any given observing program can extend for decades. Programs with small and very large allocations of observing time tend to be particularly productive per unit of observing time. For HST in general, a first publication appears within 1.5 yr for 50% of observing programs, and within 3.8 yr for 80% of programs. We discuss various external factors that affect publication metrics, their strengths and limitations for measuring scientific impact, and the challenges of making meaningful comparisons of publication metrics across missions."

Really proud to advertise our accepted peer-reviewed paper analyzing the impact of MAST through analysis of 37,000 papers published in 40 journals over the last 50 years. It's a capstone to decades of work by dozens of MAST staff. Check out the preprint: arxiv.org/abs/2512.18101 (1/3) πŸ”­

The images are in color: Jupiter and Saturn in hues of orange, yellow, and brown, while Neptune and Uranus are shades of blue. The images are highly detailed, such that structures in their atmospheres like cloud bands are clearly visible.

An example of a light curve from TESS-YSO. The image depicts a line graph with "Normalized Flux" on the y-axis and "Time" on the x-axis. On a white background, mostly black points form a tight curve with quasi-periodic rises and falls, representing the source star's brightness as it changes with time. A few cyan points are in the sequence as well, which represent data points with quality issues.

Right: Same image after subtracting the diffuse galaxy light and smoothing, with HΞ± emission (green) overlaid. This processing reveals compact sources and filamentary structures otherwise hidden by the galaxy’s brightness. Many yellow point sources are M87 globular clusters, while blue objects include background galaxies and young stellar sources within M87. North is up and East is left.

This figure describes Optical RGB composites of LACOS galaxies using WFC3/UVIS images. Red corresponds to the F850LP filter, green to the F547M filter and blue to the F438W filter. Images in each filter are normalized to their own maximum to highlight structural differences across different bands.
