LEDA 1313424

LEDA 1313424 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 LEDA 1313424 rather than just read about it. In short: LEDA 1313424 (also known as the Bullseye Galaxy) is a collisional ring galaxy (CRG) located in the Pisces constellation around 551 million light years from Earth. It is notable for its nine identified rings making it the galaxy with the highest number of rings discovered.

Reference excerpt

LEDA 1313424 (also known as the Bullseye Galaxy) is a collisional ring galaxy (CRG) located in the Pisces constellation around 551 million light years from Earth. It is notable for its nine identified rings making it the galaxy with the highest number of rings discovered. About 50 million years ago, a blue dwarf galaxy collided with LEDA 1313424 through its central region, initiating a burst of star formation and causing it to have an active galactic nucleus (AGN). The impactor is currently 130,000 light years from LEDA 1313424. This classification as a CRG is disputed by astronomers including Barry Madore and Alar Toomre. They believe LEDA 1313424 is just a tightly wound spiral galaxy like NGC 488. It is believed that doppler shift measurements of different parts of the galaxy should be able to resolve the dispute.

Morphology

Currently, nine rings have been identified in LEDA 1313424 with several 'piled up' near the central region of the galaxy and others extending tens of kiloparsecs from the center of the galaxy (~70 kpc). The outskirts of the galaxy have numerous star formation regions which surround the much redder inner ring structures.

Collision Event Around 50 million years ago, a small blue dwarf galaxy merged with LEDA 1313424 nearly head-on. The galaxy passed through the central region of LEDA 1313424 at an estimated speed ranging from 500-2000 kilometers per second. This collision event with the dwarf galaxy passing through the center of the galaxy is how LEDA 1313424 received its nickname.

Worked examples

Example 1 — a first encounter with LEDA 1313424

Start with the simplest possible case. Write down what LEDA 1313424 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 LEDA 1313424 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 LEDA 1313424 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 LEDA 1313424

In research: LEDA 1313424 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 LEDA 1313424 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: LEDA 1313424 is common in secondary-school and first-year university syllabi. It links to neighbouring topics LEDA objects, Pisces (constellation), Ring galaxies, so understanding it makes those chapters shorter.
In everyday life: Look for LEDA 1313424 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.
