The Wide-field Infrared Survey Explorer (WISE) and IRSA announce the NEOWISE Post-Cryo Data Release.
The 2013 NEOWISE Post-Cryo Data Release contains 3.4 and 4.6 micron (W1 and W2) Single-exposure image and extracted source data that were acquired by WISE following the exhaustion of solid hydrogen in the satellite's payload inner and outer cryogen tanks. During this period, known as the NEOWISE Post-Cryo survey phase, the WISE optics and focal plane assemblies warmed to 73.5 K, and the W1 and W2 HgCdTe detectors continued to operate with sensitivities close to those achieved during the full cryogenic mission phase. WISE scanned approximately 70% of the sky during the Post-Cryo phase, completing a survey of the inner Main Asteroid Belt, and a second coverage epoch of the inertial sky. The 2013 NEOWISE Post-Cryo Release supersedes the 2012 Post-Cryo Preliminary Release.

IRSA and the U.S. Planck Data Center announce the release of enhanced visualization and catalog search tools for the Planck Catalog of Compact Sources and the Planck Sunyaev-Zeldovich catalogs. In addition, compact subsets of the Markov Chains for cosmological parameters (which explore a variety of cosmological models with combinations of Planck and other data) and an updated version of the healpix2tan software (for producing on the fly tangent plane cutouts from healpix all-sky maps), are being made available.

IRSA announces the first release of the Spitzer Frontier Fields data. Using Director's Discretionary observing time, Spitzer and Hubble are undertaking a revolutionary three-year deep field observing program to peer deeper into the Universe than ever before. The Frontier Fields will combine the power of Spitzer and HST with the natural gravitational telescopes of high-magnification clusters of galaxies. These will be the second deepest observations of blank fields and deepest observations of clusters and their lensed galaxies ever obtained.

2MASS image of IRAS 20306+4005, an object in the Infrared Astronomical Satellite (IRAS)
catalog of sources. Little is known about this object, but it appears to be a region of current massive star formation in
the Galactic plane and near the Cygnus 0B2 stellar association. This is the first known near-infrared image of this source.
Infrared-bright filaments of gas surround a young cluster of stars and young stellar objects still embedded in their natal
dusty molecular cloud. A large patch of heavily-obscuring dust is seen to the north of the nebula. 2MASS is ideal for
investigating the nature of many IRAS objects and other very young star-forming regions throughout the Galaxy.
