IC 2560

IC 2560 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 IC 2560 rather than just read about it. In short: IC 2560 is a spiral galaxy lying over 110 million light-years away from Earth in the constellation of Antlia. It was discovered by Lewis Swift on 28 December 1897.

Key takeaways

IC 2560 belongs to astronomy; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect IC 2560 to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of IC 2560 from memory before moving on to harder problems.

Reference excerpt

IC 2560 is a spiral galaxy lying over 110 million light-years away from Earth in the constellation of Antlia. It was discovered by Lewis Swift on 28 December 1897. The luminosity class of IC 2560 is II with a broad HI line containing regions of ionized hydrogen. Moreover, IC 2560 is an active Type 2 Seyfert Galaxy. It has a distinct bar structure in the center with the supermassive black hole at the core having a mass of 4.4+4.4−2.2×106 M☉. One supernova has been observed in IC 2560. SN 2020ejm (type Ia, mag. 16) was discovered by the Distance Less Than 40 Mpc Survey (DLT40) on 11 March 2020.

NGC 3223 group IC 2560 is a member of the NGC 3223 Group. There are 15 other galaxies in the group including NGC 3223, NGC 3224, NGC 3258, NGC 3268, NGC 3289, IC 2552 and IC 2559. Together, the group is part of the Antlia Cluster.

Worked examples

Example 1 — a first encounter with IC 2560

Start with the simplest possible case. Write down what IC 2560 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 IC 2560 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 IC 2560 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 IC 2560

In research: IC 2560 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 IC 2560 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: IC 2560 is common in secondary-school and first-year university syllabi. It links to neighbouring topics Antlia, Astronomical objects discovered in 1897, Barred spiral galaxies, so understanding it makes those chapters shorter.
In everyday life: Look for IC 2560 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.

Frequently asked questions

What is IC 2560 in simple terms?

IC 2560 is a spiral galaxy lying over 110 million light-years away from Earth in the constellation of Antlia. It was discovered by Lewis Swift on 28 December 1897.

Why does IC 2560 matter?

Because it connects several astronomy ideas at once: it gives you a definition you can apply, a quantity you can calculate, and a way to check whether a result is plausible.

How should I study IC 2560?

Read the excerpt, restate it from memory, then work through the examples and applications listed on this page. The five-step study plan above takes about twenty minutes.
