NGC 3054

NGC 3054 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 3054 rather than just read about it. In short: NGC 3054 is an intermediate spiral galaxy in the constellation Hydra. Its velocity with respect to the cosmic microwave background is 2,758±24 km/s, which corresponds to a Hubble distance of 132.7 ± 9.4 Mly (40.68 ± 2.87 Mpc).

Key takeaways

NGC 3054 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 3054 to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of NGC 3054 from memory before moving on to harder problems.

Reference excerpt

NGC 3054 is an intermediate spiral galaxy in the constellation Hydra. Its velocity with respect to the cosmic microwave background is 2,758±24 km/s, which corresponds to a Hubble distance of 132.7 ± 9.4 Mly (40.68 ± 2.87 Mpc). However, 21 non-redshift measurements give a closer mean distance of 96.98 ± 6.35 Mly (29.733 ± 1.946 Mpc). It was discovered by German–American astronomer Christian Peters on 3 April 1859.

NGC 3054 group NGC 3054 is the brightest galaxy in the NGC 3054 group (also known as LGG 185). The other galaxies in the group are NGC 3051, NGC 3078, NGC 3084, NGC 3089, IC 2531, IC 2537, ESO 499-26, and ESO 499-32.

Supernovae Three supernovae have been observed in NGC 3054:

SN 2004de (type unknown, mag. 14.5) was discovered by Berto Monard on 15 July 2004. SN 2006T (Type IIb, mag. 17.4) was discovered by Berto Monard on 30 January 2006. SN 2022crv (Type Ib, mag. 18.0457) was discovered by the Distance Less Than 40 Mpc (DLT40) survey on 19 February 2022.

Worked examples

Example 1 — a first encounter with NGC 3054

Start with the simplest possible case. Write down what NGC 3054 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 3054 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 3054 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 3054

In research: NGC 3054 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 3054 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 3054 is common in secondary-school and first-year university syllabi. It links to neighbouring topics Astronomical objects discovered in 1859, Discoveries by Christian Peters, ESO objects, so understanding it makes those chapters shorter.
In everyday life: Look for NGC 3054 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.
