Warning from Space

Warning from 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 Warning from Space rather than just read about it. In short: Warning from Space (Japanese: 宇宙人東京に現わる, Hepburn: Uchūjin Tōkyō ni arawaru; lit. 'Spacemen Appear in Tokyo') is a 1956 Japanese tokusatsu science fiction film directed by Koji Shima. It was written by Hideo Oguni based on Gentaro Nakajima's novel.

Key takeaways

  • Warning from 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 Warning from Space to a quantity you can measure, compute or draw — that is where exam questions come from.
  • Reproduce the core statement of Warning from Space from memory before moving on to harder problems.

Reference excerpt

Warning from Space (Japanese: 宇宙人東京に現わる, Hepburn: Uchūjin Tōkyō ni arawaru; lit. 'Spacemen Appear in Tokyo') is a 1956 Japanese tokusatsu science fiction film directed by Koji Shima. It was written by Hideo Oguni based on Gentaro Nakajima's novel. In the film's plot, starfish-like aliens "Pairan" (Japanese: パイラ人, Hepburn: Pairajin) disguised as humans travel to Earth to warn of the imminent collision of a rogue planet and Earth. As the planet rapidly accelerates toward Earth, a nuclear device is created at the last minute and destroys the approaching world. Produced and distributed by Daiei Film under Masaichi Nagata, it was the first colored Japanese science fiction film, and was also the nation's first full-scaled science fiction film to feature an extraterrestrial race. The film also predates Daiei's most iconic tokusatsu characters, Gamera and Daimajin. Its special effects director was Toru Matoba, a notable figure among the tokusatsu genre who contributed in Ultraman-related contents and Spectreman after the 1956 film, and the prominent avant-garde artist Tarō Okamoto was Pairan's designer.

Plot A small ship travels to a rotating space station. Aboard the station, a group of starfish-like aliens called Pairans discuss how to warn humans of an impending disaster, deciding on contacting Japanese scientist Dr. Komura. Meanwhile, flying saucers are spotted over the skies of Tokyo, baffling scientists. A journalist tries to get a statement from Dr. Komura about the sightings, but Komura replies that there is not enough evidence to formulate a hypothesis. At an observatory, Professor Isobe spots an object in his telescope apparently releasing smaller objects. Isobe discusses his findings with Kumara and a physician, Dr. Matsuda, who believes they should get photographs via a rocket. The photographs they retrieve, however, turn out to be unclear, though they deduce the object has a high energy output. In the meantime, the extraterrestrials have been unsuccessfully attempting to contact humans. They begin appearing in lakes and rivers, frightening local fishermen and sailors. One of the aliens manages to secure a photo of Hikari Aozora, a famous Japanese entertainer. Their plan is for one of the aliens to mutate into the form of Aozora. Back aboard the space station, one of the Pairan leaders, Ginko, volunteers herself. Her starfish form is slowly mutated into a human form.

On Earth, Toru, Isobe's son, discovers the disguised alien floating in the water. After her rescue, Ginko exhibits superhuman characteristics such as jumping ten feet into the air and being able to materialize in different places without needing to walk. Soon, she disrupts Dr. Matsuda's work on a nuclear device, explaining she understands the complex equations he was writing and warning against the effects of a device, leading him to believe she is not human. Shortly afterwards, as the team of scientists discuss her abnormal traits, the camouflaged Ginko appears and reveals her true identity, explaining she is from Paira, a world on the same orbit as Earth but on the opposite side of the Sun. She then continues to reveal her mission, to warn Earth of an imminent collision of a rogue planet, which is dubbed "Planet R" by the media. They send a formal letter to the World Congress, which treats their communication with silent contempt (Japanese: mokusatsu). It takes Planet R's acceleration towards Earth being viewed through the observatory telescope for the World Congress to act. Believing that humanity could resolve the crisis on its own, every nuclear-capable nation on Earth launches its nuclear weapons at the rogue planet, which ineffectively explode on its surface. In the meantime, a group of spies have abducted Matsuda and are attempting to steal his formula to the nuclear device. Matsuda does not comply and is eventually tied to a chair in a remote building. Planet R begins its closest approach to Earth and begins to wreak havoc, first by causing the atmosphere's temperature to rise to dangerous levels. Following the disruption to the climate, powerful tidal interactions between Earth and Planet R trigger massive earthquakes, followed by tsunamis which inundate coastal areas of Japan. As Earth's destruction approaches, Ginko returns to find that Planet R has not been destroyed. She locates Matsuda through Pairan technology and gathers the formula for the nuclear device, returning to the space station to load the completed weapon into a missile. As the scientists watch, the Pairans fire the missile, which impacts and destroys Planet R, buffeting the Earth with a shock wave, but saving it from total destruction. As the climate returns to normal, Ginko changes back to her original form aboard the space station.

Worked examples

Example 1 — a first encounter with Warning from Space

Start with the simplest possible case. Write down what Warning from 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 Warning from 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 Warning from 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 Warning from Space

In research
Warning from 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 Warning from 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
Warning from Space is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1950s space adventure films, 1956 Japanese films, 1956 films, so understanding it makes those chapters shorter.
In everyday life
Look for Warning from 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.
