NGC 1511

NGC 1511 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 1511 rather than just read about it. In short: NGC 1511 is a barred spiral galaxy in the constellation of Hydrus. Its velocity with respect to the cosmic microwave background is 1341 ± 5 km/s, which corresponds to a Hubble distance of 19.76 ± 1.39 Mpc (~64 million light-years).

Key takeaways

NGC 1511 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 1511 to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of NGC 1511 from memory before moving on to harder problems.

Reference excerpt

NGC 1511 is a barred spiral galaxy in the constellation of Hydrus. Its velocity with respect to the cosmic microwave background is 1341 ± 5 km/s, which corresponds to a Hubble distance of 19.76 ± 1.39 Mpc (~64 million light-years). It was discovered by British astronomer John Herschel on 2 November 1834.

Morphology Eskridge, Frogel, and Pogge published a paper in 2002 describing the morphology of 205 closely spaced spiral or lenticular galaxies. The observations were made in the H-band of the infrared and in the B-band (blue). Eskridge and colleagues described NGC 1511 as:

Nearly edge-on. SW side of bulge is hidden by a prominent dust band, indicating that the bulge is small. Inner SE spiral arm has several very bright star-forming knots. Arms do not appear very extended (may be due to foreshortening), but there is an extended, featureless LSB [Low Surface Brightness] disk beyond the arms.

NGC 1511 Group According to A.M. Garcia, the galaxy NGC 1511 is the central member of the NGC 1511 group (also known as LGG 107) that includes NGC 1473 and NGC 1511A. Some sources also include the galaxy ESO 54-21 in this group.

Supernova One supernova has been observed in NGC 1511: SN 1935C (type unknown, mag. 12.5). The supernova was discovered by Emily Hughes Boyce on 16 August 1935, and was initially thought to be either a supernova, or a nova associated with the Large Magellanic Cloud. It was classified as a nova, and known as either HV 11970 or Nova Hydri 1935. In September 1988, Sidney Van den Bergh and Martha L. Hazen concluded definitively that the object was a supernova in NGC 1511, and the star was given the designation SN 1935C.

Worked examples

Example 1 — a first encounter with NGC 1511

Start with the simplest possible case. Write down what NGC 1511 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 1511 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 1511 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 1511

In research: NGC 1511 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 1511 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 1511 is common in secondary-school and first-year university syllabi. It links to neighbouring topics Astronomical objects discovered in 1834, Barred spiral galaxies, Discoveries by John Herschel, so understanding it makes those chapters shorter.
In everyday life: Look for NGC 1511 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.
