Congratulations on the success of our partner conference—‘’Multi-Wavelength Astronomy Collaboration towards the New Era with Deep Survey Data’’ (NEP conference 2020). You are invited to come and experience the highlights of this conference in our Twitter @Galaxies_MDPI.

The north ecliptic pole (NEP) field is a natural deep field location, and it has been a stronghold of extragalactic sciences since the AKARI space telescope brought us the valuable infrared (IR) data. Many follow-up observations to get various multi-wavelength data sets from ultraviolet (UV) to the sub-mm range have been carried out for a long time. Recently, international collaborations based on this NEP data have been quite successful and made distinguished progress.

The NTHU cosmology group has been leading this collaboration by holding international conferences, to exchange ideas/interests and share recent progress with many scientists from around the world. Face-to-face meetings or conferences present good opportunities to invite outstanding scholars and to offer desirable platforms to interact with colleagues directly. Even for the graduate student, this provides excellent experience and the chance to learn things about the hottest issues of the time. The main issues under consideration are based on IR astronomy, galaxy evolution, and observational cosmology but actually cover much wider fields, including observational and theoretical aspects of astronomy.

We are sure that this NEP field will be the ‘’Central Hub’’ for extragalactic sciences in the near future, not only because our current status is even more productive and promising but also because many future space telescopes, such as JWST, Euclid, SPHEREx, and eROSITA, will take deep field observations on this NEP. We expect our current international collaboration will bring extensive synergy with the preexisting data as well as the many projects for observations in the upcoming era of big data science.
