NGC 2276

NGC 2276 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 2276 rather than just read about it. In short: NGC 2276 is an intermediate spiral galaxy in the constellation Cepheus. The galaxy lies 120 million light-years away from Earth.

Key takeaways

NGC 2276 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 2276 to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of NGC 2276 from memory before moving on to harder problems.

Reference excerpt

NGC 2276 is an intermediate spiral galaxy in the constellation Cepheus. The galaxy lies 120 million light-years away from Earth. NGC 2276 has an asymmetrical appearance, most likely caused by gravitational interactions with its neighbor, elliptical galaxy NGC 2300. NGC 2276 is traveling with an orbital velocity of about 968 km/s relative to the NGC 2300 group of galaxies. Trailing NGC 2276 is a long tail of interstellar medium about 300,000 light-years (100,000 pc) long, formed by ram pressure stripping. One of the many starburst spiral arms contains an intermediate mass black hole with 50,000 times the mass of the Sun, named NGC 2276-3c. NGC 2276-3c has produced two jets: a large-scale radio jet, approximately 2,000 light years long, and an "inner jet" about 6 light years long. The galaxy shows an enhanced rate of star formation that may have been triggered by a collision with a dwarf galaxy, or by the gravitational interaction with its neighbor compressing gas and dust. NGC 2276 was discovered by Friedrich August Theodor Winnecke on 26 June 1876. In the Atlas of Peculiar Galaxies, the galaxy is mentioned twice, once as Arp 25, in the category spiral galaxies with one heavy arm, and with NGC 2300 as Arp 114, in the category elliptical galaxies close to and perturbing spiral galaxies.

Supernovae Six supernovae have been observed in NGC 2276:

SN 1962Q (type unknown, mag. 16.9) was discovered by Shachbazian and Iskudarian on 25 February 1962. SN 1968V (Type II, mag. 15.7) was discovered by Shachbazian on 26 January 1968. SN 1968W (type unknown, mag. 16.6) was discovered by Iskudarian on 24 March 1968. SN 1993X (Type II, mag. 16.3) was discovered by the Leuschner Observatory Supernova Search on 22 August 1993. SN 2005dl (Type II, mag. 17.1) was discovered by Alessandro Dimai (bio-it) and Marco Migliardi on 25 August 2005. SN 2016gfy (Type II, mag. 16.3) was discovered by Alessandro Dimai on 13 September 2016.

Worked examples

Example 1 — a first encounter with NGC 2276

Start with the simplest possible case. Write down what NGC 2276 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 2276 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 2276 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 2276

In research: NGC 2276 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 2276 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 2276 is common in secondary-school and first-year university syllabi. It links to neighbouring topics Arp objects, Cepheus (constellation), IRAS catalogue objects, so understanding it makes those chapters shorter.
In everyday life: Look for NGC 2276 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.
