Signs of planet formation may appear earlier than expected around still-forming baby stars, according to new results of higher resolution images produced using new improved techniques to reanalyze radio astronomy archive data. These newly…

A Demonstration of Interstellar Navigation Using New Horizons
As NASA’s New Horizons spacecraft exits the solar system bound for interstellar space, it has traveled so far that the nearest stars have shifted markedly from their positions seen from Earth. We demonstrated this by imaging the Proxima…

The CHILES Continuum and Polarization Survey. II. Radio Continuum Source Catalog and Radio Properties
The COSMOS H I Large Extragalactic Survey (CHILES) Continuum and Polarization survey is an ultradeep continuum imaging study of the COSMOS field conducted using the Karl G. Jansky Very Large Array. We obtained 1000 hr of L-band (λ = 20 cm)…

A Panchromatic Characterization of the Evening and Morning Atmosphere of WASP-107 b: Composition and Cloud Variations, and Insight into the Effect of Stellar Contamination
Limb-resolved transmission spectroscopy has the potential to transform our understanding of exoplanetary atmospheres. By separately measuring the transmission spectra of the evening and morning limbs, these atmospheric regions can be individually…

Erratum: “Deepest Limits on Scattered Light Emission from the Epsilon Eridani Inner Debris Disk with HST/STIS” (2024, AJ, 168, 169)
In the published article, there was an error in Figures 5 and 6, containing contrast curves for different postprocessing techniques. This only affects the “mJy as−2” axis. To convert from contrast to mJy as−2, there is first a middle step to…

The CHILES Continuum and Polarization Survey. I. Survey Design and Noise Characterization
We introduce and describe the CHILES Continuum and Polarisation (CHILES Con Pol) Survey, a 1000 hr 1.4 GHz wideband full polarization radio continuum deepfield with the Very Large Array, commensurate with the CHILES H i deepfield. We describe the…

NASA People Are Explorers – Not Sheep
Keith’s note: NASA Associate Administrators & Center Directors are told by the Acting Administrator to get more people to quit. Non-compliance by CDs/AAs will lead to their firing. And yes, there will be RIFs. Monday’s protest is a start. So,…
