Question 1

True or false: The star system Eta Carinae is invisible from Earth without a telescope.

Accepted Answer

False. It was visible to the naked eye during its 1843 eruption and can occasionally be seen under dark skies.

Question 2

True or false: Eta Carinae is located in the constellation Orion.

Accepted Answer

False. It lies in the southern constellation Carina, not Orion. Carina was once part of the larger Argo Navis.

Question 3

True or false: Eta Carinae is the closest known supernova candidate to Earth.

Accepted Answer

False. While it is about 7,500 light-years away, several closer supernova candidates exist, like Betelgeuse.

Question 4

True or false: The Homunculus Nebula around Eta Carinae is made of material ejected during its 19th-century eruption.

Accepted Answer

True. This bipolar nebula consists of gas and dust expelled during the Great Eruption, expanding outward.

Question 5

True or false: Eta Carinae is one of the most massive and luminous stars known in our galaxy.

Accepted Answer

True. Eta Carinae has an estimated mass around 100 times that of the Sun and shines millions of times brighter.

Question 6

True or false: Eta Carinae's Great Eruption in the 1840s made it the second brightest star in the sky for a time.

Accepted Answer

True. From 1837 to 1856 it brightened dramatically, briefly outshining all but Sirius.

Question 7

True or false: The Eta Carinae system contains at least two massive stars orbiting each other.

Accepted Answer

True. It is a binary system with a primary star of about 100 solar masses and a hotter companion of about 30-60 solar masses.

Question 8

True or false: Eta Carinae's next eruption is predicted to occur within the next 50 years.

Accepted Answer

False. Its behavior is unpredictable; while a supernova could happen anytime, no specific timeline is reliably forecast.
