As a foundation for SFiNCs, catalogs of 15,300 X-ray and 1,630,000 mid-IR point sources are presented. ~8500 point sources are identified as probable young stellar members of 22 nearby star-forming regions.

Two infrared transients have been discovered in a nearby galaxy that are likely obscured supernovae. This discovery suggests that current optical surveys may be missing >18% of nearby core-collapse supernovae.

Simulations suggest that it should be possible to detect between 1.4 and 7.9 free-floating planets in the K2 data set. Most will also have ground-based observations, enabling parallax measurements.

A likely moon has been discovered of 2007 OR10, the third largest known dwarf planet in the trans-Neptunian region. All trans-Neptunian objects larger than 1000 km are now known to harbor satellites.

Comparing new simulation outcomes with EHT observations favors models with ordered magnetic fields near the black hole event horizon in Sgr A*. The emission could still be either disk- or jet-dominated.

Dust emission from a protostar in the massive protocluster NGC 6334I increased by a factor of 4 between 2008 and 2015, providing observational evidence of a sudden accretion event in the protostar’s growth.
