NGC 4026

NGC 4026 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 4026 rather than just read about it. In short: NGC 4026 is an edge-on lenticular galaxy in the constellation Ursa Major. It is located at a distance of circa 50 million light years from Earth, which, given its apparent dimensions, means that NGC 4026 is about 80,000 light years across.

Key takeaways

NGC 4026 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 4026 to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of NGC 4026 from memory before moving on to harder problems.

Reference excerpt

NGC 4026 is an edge-on lenticular galaxy in the constellation Ursa Major. It is located at a distance of circa 50 million light years from Earth, which, given its apparent dimensions, means that NGC 4026 is about 80,000 light years across. It was discovered by William Herschel on April 12, 1789. The galaxy hosts a supermassive black hole with estimated mass 108.33±0.109 (166-275 million) M☉.

Nearby galaxies NGC 4026 belongs to M109 Group, the largest subgroup of galaxies with the Ursa Major Cluster. In the vicinity of NGC 4026 lie some low surface brightness spiral galaxies, UGC 6917 (42 arcminutes from NGC 4026), UGC 6922 (26 arcminutes from NGC 4026) and UGC 6956 (10 arcminutes from NGC 4026). NGC 4026 appears disturbed in HI imaging, with a filament extending southward. The mass of HI in NGC 4026 is below 0.71 × 108 M⊙. The total HI mass in NGC 4026, UGC 6956 and the HI filament is estimated to be 7.94 × 108 M⊙. This phenomenon has been studied and evidence implies the presence of tidal forces and tidal interactions between the galaxies.

Worked examples

Example 1 — a first encounter with NGC 4026

Start with the simplest possible case. Write down what NGC 4026 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 4026 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 4026 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 4026

In research: NGC 4026 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 4026 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 4026 is common in secondary-school and first-year university syllabi. It links to neighbouring topics Lenticular galaxies, M109 Group, NGC objects, so understanding it makes those chapters shorter.
In everyday life: Look for NGC 4026 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.
