  Exoplanet research has shown an incessant growth since the first claim of a
hot giant planet around a solar-like star in the mid-1990s. Today, the new
facilities are working to spot the first habitable rocky planets around
low-mass stars as a forerunner for the detection of the long-awaited Sun-Earth
analog system. All~the achievements in this field would not have been possible
without the constant development of the technology and of new methods to detect
more and more challenging planets. After the consolidation of a top-level
instrumentation for high-resolution spectroscopy in the visible wavelength
range, a huge effort is now dedicated to reaching the same precision and
accuracy in the near-infrared. Actually, observations in this range present
several advantages in the search for exoplanets around M dwarfs, known to be
the most favorable targets to detect possible habitable planets. They are also
characterized by intense stellar activity, which hampers planet detection,
but~its impact on the radial velocity modulation is mitigated in the infrared.
Simultaneous observations in the visible and near-infrared ranges appear to be
an even more powerful technique since they provide combined and complementary
information, also useful for many other exoplanetary science~cases.
