UFO sightings in outer space

UFO sightings in outer space is a astronomy topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand UFO sightings in outer space rather than just read about it. In short: Unidentified flying objects have been reported by astronauts while in space. These sightings have been claimed as evidence for extraterrestrial life by ufologists.

Key takeaways

UFO sightings in outer space belongs to astronomy; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect UFO sightings in outer space to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of UFO sightings in outer space from memory before moving on to harder problems.

Reference excerpt

Unidentified flying objects have been reported by astronauts while in space. These sightings have been claimed as evidence for extraterrestrial life by ufologists. Some of the alleged sightings never occurred: science fiction writer Otto Binder perpetuated a hoax claiming Apollo 11 Commander Neil Armstrong had encountered UFOs during the Apollo mission. UFO proponents see comments by astronauts or photos processed by NASA as one of the "strongest bodies of evidence" because they are considered to be of high trustworthiness; however, NASA Assistant Administrator for Legislative Affairs, Robert F. Allnut, concluded in a 1970 letter, "after fifteen years of manned space voyages including space stations and landing on the Moon, spacemen have brought back not a shred of evidence – verbal, photographic, or otherwise – for the existence of extraterrestrial spacecraft, or 'UFOs'." In 2009, footage from NASA was posted on YouTube by ufologists which "renew[ed] UFO conspiracy theories that the government is hiding knowledge about its interactions with intelligent life" by relying on a "lack of context" to promote a "collection of indistinct imagery and allegations". A number of the incidents were collected for an episode of the 2014 television series Are We Alone?.

Worked examples

Example 1 — a first encounter with UFO sightings in outer space

Start with the simplest possible case. Write down what UFO sightings in outer space claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In astronomy, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to UFO sightings in outer space before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about UFO sightings in outer space ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of UFO sightings in outer space

In research: UFO sightings in outer space appears in astronomy research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses UFO sightings in outer space in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: UFO sightings in outer space is common in secondary-school and first-year university syllabi. It links to neighbouring topics Space and astronomy conspiracy theories, UFO conspiracy theories, UFO sightings, so understanding it makes those chapters shorter.
In everyday life: Look for UFO sightings in outer space outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
