: The physical metal plate used to hold optical fibers in the telescope. MJD : The date the observation took place.
The SDSS uses a dedicated 2.5-meter telescope at Apache Point Observatory in New Mexico to map the universe [2, 5]. By cataloging objects like 357959_5727-5712, astronomers can: 357959_5727-5712
This object is a galactic nucleus where a supermassive black hole is actively "feeding" on surrounding gas and dust [4]. As this material spirals into the black hole, it heats up to millions of degrees, releasing more light than an entire galaxy of hundreds of billions of stars [6]. 2.

This specific identifier belongs to a dataset from the , one of the most ambitious and influential surveys in the history of astronomy [2, 5]. Why the SDSS Matters This specific identifier belongs
: Determine how fast the object is moving away from us, which tells us its distance and the age of the universe when that light was emitted [7].
