The Max-Planck-Institut für Kernphysik ("MPI for Nuclear Physics" or MPIK for short) is a research institute in Heidelberg, Germany. The institute is one of the 80 institutes of the Max-Planck-Gesellschaft (Max Planck Society), an independent, non-profit research organization. The Max Planck Institute for Nuclear Physics was founded in 1958 under the leadership of Wolfgang Gentner. Its precursor was the Institute for Physics at the MPI for Medical Research. Today, the institute's research areas are: crossroads of particle physics and astrophysics (astroparticle physics) and many-body dynamics of atoms and molecules (quantum dynamics). The research field of Astroparticle Physics, represented by the divisions of Jim Hinton, Werner Hofmann and Manfred Lindner, combines questions related to macrocosm and microcosm. Unconventional methods of observation for gamma rays and neutrinos open new windows to the universe. What lies behind “dark matter” and “dark energy” is theoretically investigated. The research field of Quantum Dynamics is represented by the divisions of Klaus Blaum, Christoph Keitel and Thomas Pfeifer. Using reaction microscopes, simple chemical reactions can be “filmed”. Storage rings and traps allow precision experiments almost under space conditions. The interaction of intense laser light with matter is investigated using quantum-theoretical methods. Further research fields are cosmic dust, atmospheric physics as well as fullerenes and other carbon molecules. Scientists at the MPIK collaborate with other research groups in Europe and all over the world and are involved in numerous international collaborations, partly in a leading role. Particularly close connections to some large-scale facilities like GSI (Darmstadt), DESY (Hamburg), CERN (Geneva), TRIUMF (Canada), and INFN-LNGS (Assergi L‘Aquila) exist. The institute has about 390 employees, as well as many diploma students and scientific guests. In the local region, the Institute cooperates closely with the University of Heidelberg, where the directors and further members of the Institute are teaching. Three International Max Planck Research Schools (IMPRS) and a graduate school serve to foster young scientists. The institute operates a cryogenic ion storage ring (CSR) dedicated to the study of molecular ions under interstellar space conditions. Several Penning ion traps are used to measure fundamental constants of nature, such as the atomic mass of the electron and of nuclei. A facility containing several electron beam ion traps (EBIT) that produce and store highly charged ions is dedicated to fundamental atomic structure as well as astrophysical investigations. Large cameras for gamma-ray telescopes (HESS, CTA), Dark Matter (XENON1t, DARWIN), and neutrino detectors are developed and tested on-site.

Heidelberg-Königstuhl State Observatory (German: Landessternwarte Heidelberg-Königstuhl) is a historic astronomical observatory located near the summit of the Königstuhl hill in the city of Heidelberg in Germany. The predecessor of the current observatory was originally opened in 1774 in the nearby city of Mannheim but degradation of observational conditions there resulted in a relocation to the Königstuhl in 1898.The observatory forms part of the Center of Astronomy of the University of Heidelberg. The Max Planck Institute for Astronomy opened on an adjacent site in 1967. Prof. Dr. Andreas Quirrenbach is the observatory's director since 2005.

The Max-Planck-Institut für Astronomie (Max Planck Institute for Astronomy, MPIA) is a research institute of the Max Planck Society (MPG). It is located in Heidelberg, Baden-Württemberg, Germany near the top of the Königstuhl, adjacent to the historic Landessternwarte Heidelberg-Königstuhl astronomical observatory. The institute primarily conducts basic research in the natural sciences in the field of astronomy. In addition to its own astronomical observations and astronomical research, the Institute is also actively involved in the development of observation instruments. The instruments or parts of them are manufactured in the institute's own workshops.

The Neckars Formation is a Pleistocene geologic formation in Germany. In the Sackdillinger Cave, it preserves fossils of the frogs Rana temporaria and Bufo sp. and the bear Ursus sackdillingensis.

The Königstuhl (German pronunciation: [ˈkøːnɪçˌʃtuːl]), is a 567.8 metres (1,863 ft) high hill in the Odenwald Mountains and in the city of Heidelberg, in the German state of Baden-Württemberg. The Königstuhl summit allows visitors views of the city of Heidelberg and the Neckar river. On days with good conditions the view extends to the Pfaelzerwald (Palatinate Forest), which is roughly 40–50 km away.The hill is linked to Altstadt, by the Heidelberger Bergbahn, a two section historic funicular railway that stops at Heidelberg Castle, located on the lower slopes of the Königstuhl, the Molkenkur restaurant/hotel, and the ultimate stop at the mountain top which host a restaurant, an entertainment park for kids and various walking paths. The Max Planck Institute for Astronomy is located near the summit of the Königstuhl, as is the historic Landessternwarte Heidelberg-Königstuhl astronomical observatory, established in 1898. Between 1912 and 1957, Karl Wilhelm Reinmuth discovered almost 400 asteroids whilst working from this observatory. Several telecommunications facilities are located on the Königstuhl, including the Fernsehturm Heidelberg (Digital TV (DVB-T), Radio and Microwave), the Telecom Telecommunication Tower Heidelberg (Microwave and FM) and the now inactive Telecommunication Tower of US-Forces Heidelberg (Microwave).

The Heidelberg Mountain Railway (German: Heidelberger Bergbahn) is a two-section funicular railway in the city of Heidelberg, Germany. The first section runs from a lower station at Kornmarkt in Heidelberg's Altstadt, via an intermediate station at Heidelberg Castle, to an upper station at Molkenkur. Here passengers may change to the second section, which runs up the Königstuhl, a nearby mountain with good views over the city and the River Neckar.The upper and lower sections of the funicular have different histories and are sometimes referred to separately by the names Königstuhlbahn and Molkenkurbahn respectively. These two sections present quite different appearances, with the upper section using wooden bodied cars of historic appearance, whilst the lower section uses modern style cars. Similarly the upper stations at Molkenkur and Königstuhl are to the original design, whilst those further down the hill at Kornmarkt and Heidelberg Castle present a more modern image.The Heidelberger Bergbahn is operated by the Heidelberger Straßen- und Bergbahn AG (HSB), the operator of buses and trams in Heidelberg. The funicular predominantly serves tourist traffic. The lower section runs every ten minutes throughout the day, whilst the connecting upper section runs every twenty minutes throughout the day. The services start at 9 a.m. and end at times that vary from summer to winter.

St. Peter's Church (German: Peterskirche) is the oldest church in the old town (Altstadt) of Heidelberg, Germany. It has generally served as the university church of the University of Heidelberg since the late Middle Ages.

The Corps Saxo-Borussia Heidelberg is a German Student Corps at the University of Heidelberg.

The Heidelberg University Library (German: Universitätsbibliothek Heidelberg, ISIL DE-16) is the central library of the Heidelberg University. Together with the 83 decentralized libraries of the faculties and institutes, it forms the University Library System, which is headed by the director of the University Library. The University Library holds special collections in literature concerning the Palatinate and Baden, egyptology, archeology, the history of art, and South Asia. It holds about 3.2 million books, 6,000 printed scientific periodicals, and about 500,000 other media such as microfilms and video tapes. The libraries of the faculties and institutes hold another 3 million printed books. In 2022, the University Library registered 43,600 active users who accessed more than 746,000 books. The conventional book supply is complemented by numerous electronic services, including approximately 152,00 electronic journals. The University Library provides around 1,100 reading- and workspaces in the main library in the old town and around 320 reading- and workspaces in the branch in the Neuenheimer Feld, including many IT-workstations and research stations equipped with PCs.

Mark Twain Village (MTV) was a United States Army military family housing area located in the Südstadt district of Heidelberg, Germany. It was one of the two main American family housing areas in the United States Army Garrison Heidelberg that provided quarters for American military personnel, authorized civilian employees, and their families (the other being Patrick Henry Village). MTV was located adjacent to Campbell Barracks, which served as the home to the Headquarters of United States Army Europe (USAREUR), the Headquarters for NATO's Allied Land Forces Central Europe (LANDCENT), and the Installation Management Command Europe Region (IMCOM-E). MTV was separated by a main thoroughfare. Located within the housing area was an Army and Air Force Exchange Service (AAFES) shoppette, a library, a chapel, the Mark Twain Elementary School, and the Heidelberg High School, which both served American military dependent children living in the surrounding area. The high school served students from Mark Twain Village, nearby Patrick Henry Village, and their respective surrounding areas. Heidelberg High was one of the largest DoDDS schools in Germany. It, along with all the other schools in the Heidelberg area, was closed in 2013.. Since 2017, Julius-Springer-Schule has occupied the former Heidelberg High School building at Mark-Twain-Straße 1. Most of MTV's housing area has been shut down (the area across the street from Campbell Barracks) and given back to the City of Heidelberg. Because the closed area had severed access from Campbell Barracks, the decision was made that this would be the first portion returned to the City of Heidelberg. It is currently being renovated with some buildings already accommodating German civilians.Another part of MTV's housing area is now being used by NATO personnel. For most of its existence, MTV was indistinguishable from the surrounding public residential buildings and was not fenced, gated, or otherwise closed to the general public until 2003, when a fence was installed around MTV and all other United States Army installations in Heidelberg. There was a requirement to show ID to enter the area. The entire compound, along with Campbell Barracks, was gated and required United States military ID to enter.

Heidelberg-Südstadt ("South Town") is a district of the city of Heidelberg in Baden-Württemberg, Germany. It is a relatively young district and was established after World War 2, by extending the Weststadt district to the south, and the Rohrbach district to the north. Today, it houses about 4,400 citizens (including about 600 people not registered as residentials of the suburb). Südstadt is the second-smallest district of Heidelberg by population, after Schlierbach.

Heidelberg University, officially the Ruprecht Karl University of Heidelberg, (German: Ruprecht-Karls-Universität Heidelberg; Latin: Universitas Ruperto Carola Heidelbergensis) is a public research university in Heidelberg, Baden-Württemberg, Germany. Founded in 1386 on instruction of Pope Urban VI, Heidelberg is Germany's oldest university and one of the world's oldest surviving universities. It was the third university established in the Holy Roman Empire.Heidelberg has been a coeducational institution since 1899. The university consists of twelve faculties and offers degree programmes at undergraduate, graduate and postdoctoral levels in some 100 disciplines. Heidelberg comprises three major campuses: the humanities are predominantly located in Heidelberg's Old Town, the natural sciences and medicine in the Neuenheimer Feld quarter, and the social sciences within the inner-city suburb Bergheim. The language of instruction is usually German, while a considerable number of graduate degrees are offered in English as well as some in French.As of 2021, 57 Nobel Prize winners have been affiliated with the city of Heidelberg and 33 with the university itself. Modern scientific psychiatry, psychopharmacology, psychiatric genetics, environmental physics, and modern sociology were introduced as scientific disciplines by Heidelberg faculty. Approximately 1,000 doctorates are completed every year, with more than one third of the doctoral students coming from abroad. International students from some 130 countries account for more than 20 percent of the entire student body.Heidelberg is a German Excellence University, part of the U15, as well as a founding member of the League of European Research Universities and the Coimbra Group. The university's noted alumni include eleven domestic and foreign heads of state or heads of government.
