NGC 3294

NGC 3294 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 NGC 3294 rather than just read about it. In short: NGC 3294 is a spiral galaxy in the constellation Leo Minor. It was discovered by William Herschel on Mar 17, 1787.

Key takeaways

NGC 3294 belongs to astronomy; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect NGC 3294 to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of NGC 3294 from memory before moving on to harder problems.

Reference excerpt

NGC 3294 is a spiral galaxy in the constellation Leo Minor. It was discovered by William Herschel on Mar 17, 1787. It is a member of the Leo II Groups, a series of galaxies and galaxy clusters strung out from the right edge of the Virgo Supercluster. The galaxy is located at a distance of 98 million light years and is receding with a heliocentric radial velocity of 1,586 km/s. The morphological class of NGC 3294 is SA(rs)bc, which means this is a spiral galaxy with no central bar (SA), an incomplete inner ring structure (rs), and moderately wound spiral arms (bc). This galaxy has been host to a pair of supernova events:

SN 1990H was discovered by Saul Perlmutter and Carlton Pennypacker on April 9, 1990 at a position 12″ west and 1″ south of the galactic nucleus. The spectrum and light curve resembled a Type II core-collapse supernova similar to SN 1987A. SN 1992G was discovered by Shunji Sasaki on 14 February 14 1992, 27″ east and 10.5″ south of the galaxy's nucleus. This was determined to be a Type Ia supernova.

Worked examples

Example 1 — a first encounter with NGC 3294

Start with the simplest possible case. Write down what NGC 3294 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 NGC 3294 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 NGC 3294 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 NGC 3294

In research: NGC 3294 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 NGC 3294 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: NGC 3294 is common in secondary-school and first-year university syllabi. It links to neighbouring topics Leo Minor, NGC objects, Principal Galaxies Catalogue objects, so understanding it makes those chapters shorter.
In everyday life: Look for NGC 3294 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.
