IC 2759

IC 2759 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 2759 rather than just read about it. In short: IC 2759 is a small type E elliptical galaxy located in the constellation of Leo. It is located 350 million light-years away from the Solar System and was discovered on April 24, 1897, by Guillaume Bigourdan.

Key takeaways

IC 2759 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 2759 to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of IC 2759 from memory before moving on to harder problems.

Reference excerpt

IC 2759 is a small type E elliptical galaxy located in the constellation of Leo. It is located 350 million light-years away from the Solar System and was discovered on April 24, 1897, by Guillaume Bigourdan. Sometimes IC 2759 is confused with the spiral galaxy, PGC 34882 which is located south of the galaxy. Both galaxies are members of Hickson 51.

Supernova One supernova has been discovered in IC 2759 so far: SN 2020lyo. SN 2020lyo SN 2020lyo was discovered in IC 2759 by astronomer, Dr. David Bersier on 8 June 2020 from All Sky Automated Survey for SuperNovae (ASAS-SN). via a Liverpool Telescope. It was 0".5 west and 0".0 south of the nucleus and located at redshift of 0.027. The supernova was Type Ia.

Hickson 51

IC 2759 is a member of Hickson 51. It was one of the galaxies observed by Paul Hickson, when he published his article in 1982. The other galaxies in Hickson 51, are NGC 3651, PGC 34882, NGC 3653, PGC 34907, PGC 34899 or NGC 3651 NED02 and PGC 34901. IC 2759 in this case, is listed as HCG 51E.

Worked examples

Example 1 — a first encounter with IC 2759

Start with the simplest possible case. Write down what IC 2759 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 2759 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 2759 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 2759

In research: IC 2759 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 2759 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 2759 is common in secondary-school and first-year university syllabi. It links to neighbouring topics Astronomical objects discovered in 1897, Discoveries by Guillaume Bigourdan, Elliptical galaxies, so understanding it makes those chapters shorter.
In everyday life: Look for IC 2759 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.
