abstract
(abridged) The review describes observations of SS433. The main difference between SS433 and other X-ray binaries is the supercritical regime for the gas accretion onto the relativistic star (most likely a black hole), which has lead to the formation of collimated relativistic jets. The properties of the jets are determined by their interaction with the disk wind. The precession of the disk and jets, as well as the eclipsing in the binary system, make SS433 a unique laboratory for studies of mechanisms for the microquasar phenomenon. Essentially all photometric and spectroscopic properties of SS433 are determined by the accretion disk and its orientation, but the disk itself is not observed, being located beneath the photosphere of the dense wind. Observational manifestations of the wind and of gas flows in the system are described. Little is known about the structure of the central regions where the hot bases of the jets are located. The available X-ray, UV, and optical observations point towards the picture where the bases of the jets are surrounded by cocoons of hot gas reradiating emission from the inner regions of the jet channel. Direct investigations of this channel in the supercritical accretion disk of SS433 are not possible; however, a similar object oriented face-on would likely be an extremely bright X-ray source, such as ultra-luminous X-ray sources observed in other galaxies.

X-ray timing and spectral analysis of ASKAP J174508.9-505149 detects matching periodicity and features consistent with an accreting magnetic CV.
Fermi LAT data analysis detects a time-evolving ~162-day periodic GeV signal from 4FGL J1913.2+0512 linked to SS 433, prominent in 2008-2018 but diminished afterward, indicating multi-year evolution in gamma-ray production efficiency or geometry.
17-year Fermi-LAT observations detect GeV excesses in SS 433's W50 nebula whose spectra and positions suggest acceleration of cosmic-ray protons in microquasar outflows, potentially the first such evidence.
Observational evidence links obscured super-Eddington accretion to slower precessing jets in stellar-mass compact object systems, contrasting with fixed fast jets in low-density environments.
Deep VLBI observations of four ULXs yield no compact radio detections and tight upper limits, disfavoring persistently bright hard-state-like compact cores.
