SEMANTIC ANALYSIS

The owner has associated the following topics to the website.

The results of our semantic analysis are shown below using the website's language.

They are the main concepts covered by eso.org.

Each concept has a confidence score. The higher it is, the more important the topic is relative to the page.

Topics
European Southern Observatory Confidence: 80% Arrow up

The European Southern Observatory (ESO, formally: European Organization for Astronomical Research in the Southern Hemisphere) is a 16-nation intergovernmental research organization for ground-based astronomy.

Created in 1962, ESO has provided astronomers with state-of-the-art research facilities and access to the southern sky.

The organisation employs about 730 staff members and receives annual member state contributions of approximately €131 million.

Its observatories are located in northern Chile.

Southern Hemisphere Confidence: 79% Arrow up

The Southern Hemisphere is the half sphere of Earth which is south of the equator.

It contains all or parts of five continents (Antarctica, Australia, about 90% of South America, the southern third of Africa, and several southern islands off the continental mainland of Asia), four oceans (Indian, South Atlantic, Southern, and South Pacific) and most of the Pacific Islands in Oceania.

Its surface is 80.9% water, compared with 60.7% water in the case of the Northern Hemisphere, and it contains 32.7% of Earth's land.

Astronomy Confidence: 74% Arrow up

Astronomy (from Greek: αστρονομία) is a natural science that studies celestial objects and phenomena.

It applies mathematics, physics, and chemistry, in an effort to explain the origin of those objects and phenomena and their evolution.

Objects of interest include planets, moons, stars, galaxies, and comets; while the phenomena include supernovae explosions, gamma ray bursts, and cosmic microwave background radiation.

More generally, all astronomical phenomena that originate outside Earth's atmosphere are within the purview of astronomy.

A related but distinct subject, physical cosmology, is concerned with the study of the Universe as a whole.

European Space Agency Confidence: 72% Arrow up

The European Space Agency (ESA; ASE) is an intergovernmental organisation of 22 member states, dedicated to the exploration of space.

Established in 1975 and headquartered in Paris, France, ESA has a worldwide staff of about 2,000 and an annual budget of about €5.25 billion / US$5.77 billion (2016).

Research Confidence: 69% Arrow up

Research comprises "creative work undertaken on a systematic basis in order to increase the stock of knowledge, including knowledge of humans, culture and society, and the use of this stock of knowledge to devise new applications." It is used to establish or confirm facts, reaffirm the results of previous work, solve new or existing problems, support theorems, or develop new theories.

A research project may also be an expansion on past work in the field.

Research projects can be used to develop further knowledge on a topic, or in the example of a school research project, they can be used to further a student's research prowess to prepare them for future jobs or reports.

To test the validity of instruments, procedures, or experiments, research may replicate elements of prior projects or the project as a whole.

The primary purposes of basic research (as opposed to applied research) are documentation, discovery, interpretation, or the research and development (R&D) of methods and systems for the advancement of human knowledge.

Approaches to research depend on epistemologies, which vary considerably both within and between humanities and sciences.

There are several forms of research: scientific, humanities, artistic, economic, social, business, marketing, practitioner research, life, technological,etc.
