🔍 Key Concepts

• apparent magnitude in astronomy (how bright a star appears from Earth) • difference between a single star changing brightness versus a system of two stars • how sudden, dramatic brightening events are classified compared to stars that change brightness in a regular cycle

💭 Think About

• Which term is specifically used for a star that has a sudden outburst, becoming much brighter in a short time, then slowly fading back? • Which option describes a star whose brightness changes over time in a more ongoing, repeating way, rather than one sudden event? • Which options (nebula, double star, variable star) are types of objects or systems that don’t necessarily involve a one-time sudden brightening?

✅ Before You Answer

• Match the question’s clue: suddenly becomes several magnitudes brighter – look for the term used for an outburst event. • Check which choice refers to a gas cloud rather than a star, and which refers to two stars orbiting each other – those likely don’t fit the definition given. • Ask: does the correct term usually describe a single star undergoing an eruption or just a star that regularly changes brightness? Pick the one that matches the description best.
