Very-High-Energy gamma-ray astronomy probes non-thermal, energetic acceleration processes in the Universe. The rapid development of very-high-energy gamma-ray observatories such as HAWC, VERITAS, HESS, and MAGIC expanded the TeV gamma-ray source catalog to more than two hundred sources. The list of known gamma-ray source classes includes active galaxies, supernova remnants, pulsar wind nebulae. VHE observations, in conjunction with observations at other energies/wavelengths as well as particle and now gravitational wave events, allow for an increased understanding of the physics driving these energetic systems.

In this talk, I will present recent results from observations using the HAWC and VERITAS observatories. First, I will discuss the HAWC's discovery of gamma-ray emission from SS 433, making it the first known microquasar seen at TeV energies. Another key result from HAWC is resolving the morphology of Geminga supernova remnant. A key result from VERITAS is the detection of gamma-rays from blazar TXS 0506+056 temporally coincident with a neutrino detected by IceCube. Lastly, I will discuss our future observation plans to improve our understanding of these objects.
