Answers below are taken from the article’s stored facts, so they match what the student read.

1. What is the object type?Extremely luminous submillimeter galaxy, classified as a starburst galaxy
2. Why is SMM J2135−0102 so bright?The galaxy is forming stars at a huge speed, and a closer galaxy acts like a cosmic magnifying glass, making it look even brighter to us.
3. How do scientists study SMM J2135−0102?They use powerful telescopes to look at its infrared light and the fingerprints of its gas and dust. The lensing effect helps them see more details than usual.

Submillimeter Galaxy: A galaxy that emits strongly in the submillimeter wavelengths, often associated with cold dust and active star formation.
Gravitational Lensing: The distortion and magnification of light from a distant source by the gravity of an intervening massive object.
Cosmic Chronometer: An astronomical object whose light provides information about the age and evolution of the universe at a specific cosmic epoch.
