NGC 4144

NGC 4144 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 4144 rather than just read about it. In short: NGC 4144 is a barred spiral galaxy located in the Ursa Major constellation. It was discovered by the German-born British astronomer William Herschel on April 10, 1788.

Key takeaways

NGC 4144 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 4144 to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of NGC 4144 from memory before moving on to harder problems.

Reference excerpt

NGC 4144 is a barred spiral galaxy located in the Ursa Major constellation. It was discovered by the German-born British astronomer William Herschel on April 10, 1788. The galaxy is also known by several other catalog names, including IRAS F12074+4644, 2MASX J12095860+4627258, UGC 7151, and PGC 38688. It has an apparent magnitude of 12.17 in the blue band.

Description NGC 4144 is a barred spiral galaxy classified as Im/BCD C, meaning it displays features of both irregular and blue compact dwarf galaxies. The galaxy is situated approximately 40 million light-years away from Earth. It is part of the Ursa Major Group, which consists of several galaxies in close proximity to each other. NGC 4144 is particularly notable for its faint appearance and for being relatively difficult to observe without a telescope due to its low luminosity.

Worked examples

Example 1 — a first encounter with NGC 4144

Start with the simplest possible case. Write down what NGC 4144 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 4144 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 4144 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 4144

In research: NGC 4144 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 4144 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 4144 is common in secondary-school and first-year university syllabi. It links to neighbouring topics Astronomical objects discovered in 1788, Barred spiral galaxies, Barred spiral galaxy stubs, so understanding it makes those chapters shorter.
In everyday life: Look for NGC 4144 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.
