Since the new era of infrared astronomy was opened by the Two Micron Sky Survey by Neugebauer et al. in the early 1960s, about a half century has passed. During this time, observations have expanded rapidly and widely, to almost every field of astronomy, to reveal new perspectives on the universe. As a result, infrared astronomy has become one of the major branches of astronomy, along with optical, radio, X-ray as well as high-energy particle astronomy. In Japan, we started our infrared astronomical activities at a rather early time, under relatively poor technical and environmental conditions, and using somewhat unconventional methods to overcome these difficulties. Here, a brief survey is presented of developments concerning infrared astronomy during the past half century, while mainly recollecting our footprints in the stream of world activities.

The Hubble Space Telescope has been in Earth orbit for almost 30 years, returning an amazing variety of scientific discoveries. It can be pointed via ground command to the entire panoply of astronomical objects, from nearby targets in our solar system to the most distant objects in the known universe. While these wonderful scientific results were expected by the project's founders, what have been more surprising are the cultural aspects of the program. Hubble has been embraced by the general public to an extent unprecedented for complex scientific facilities. Not only are its images widely known for their beauty, but the project itself has repeatedly entered the popular lexicon as an example of a technological pinnacle. We present examples of the numerous scientific successes, as well as popular culture memes related to Hubble. Finally, it is also important to ponder the broader question of why we conduct astronomical research.

The Indo-European debate has been going on for a century and a half. Initially confined to linguistics, race-based anthropology and comparative mythology, it soon extended to archaeology, especially with the discovery of the Harappan civilization, and peripheral disciplines such as agriculture, archaeometallurgy or archaeoastronomy. The latest entrant in the field, archaeogenetics, is currently all but claiming that it has finally laid to rest the whole issue of a hypothetical migration of Indo-Aryan speakers to the Indian subcontinent in the second millennium BCE. This paper questions the finality of this claim by pointing to inherent limitations, methodological issues and occasional biases in current studies as well as in the interpretation of archaeological evidence.
