Abstract
The observational data for the extragalactic research are evolved across this century.
While the first studies on galaxies were essentially based on images and spectra
taken in the optical waveband and registered after hours of work at the telescope on
glass photographic plates, today we receive pre-reduced multiwavelength images
and spectra directly on our computers. The work of astronomers is changed completely
with the technological progress. Only 30 years ago, 4-5 photographic images
of galaxies, or a few spectra, were the best one can hope to get after a night of hard
work at the telescope. Today, space and ground-based telescopes with big diameters
and field of view are pointed toward the sky every night, collecting gigabytes of data
for thousand of galaxies, that we bring with us in our laptop computers.
In the previous chapters the aim of our interviews was to clarify whether this exponential
increase of observational data available for the extragalactic research has
been accompanied by a parallel significant growth in our understanding of galaxies.
In this chapter on the other hand, we try to offer an overview of the future scheduled
or planned projects for the extragalactic research. The discussion will therefore address
the most important space and ground based telescopes that have been imaged
for the next future. The aim is that of clarify what are the main open questions in
extragalactic astronomy and what efforts will be put forward to find their solutions.
The Chapter starts with the Gaia mission that is currently mapping the stellar
component of the MilkyWay (MW) with unprecedented accuracy in the astrometric
positions, but it is also expected to provide an incredibly large database for galaxies
and quasars positions. From these interviews we will gain a useful insight about the
enormous range of byproducts of the MW studies for the extragalactic research. We then address our discussion toward the most attractive telescope projects from
space and from the ground. In turn, we will focus our interviews on the JamesWebb
Space Telescope (JWST), the post-Hubble largest NASA project, and the next IR,
UV, X-ray and Gamma-ray space missions of the west countries for the years to
come. We will later explore the future view of galaxies coming from the ground
based telescopes, like the Extremely Large Telescope (ELT) and the Large Synoptic
Survey Telescope (LSST). The chapter will then offers a panoramic sketch of the
extragalactic projects engaged in the east countries. Finally, we discuss the contribution
of radio astronomy to the new galaxy view, examining the contribution of the
Atacama Large Millimiter Array (ALMA) and the results expected from the Square
Kilometer Array (SKA).
