What type of star is HOPS-68? And what human phase of life could we consider this star to be in?
*
1 point
Protostar; baby
Protostar; elderly
Main Sequence; adult life
Neutron Star; death
HOPS-68 is considered a protostar. In terms of a human phase of life, we can consider this star to be in its "baby" phase.
Our sun is in which phase of its life? Nuclear fusion will burn all of the hydrogen in its core and then it will begin its next phase of life. Astronomers estimate this will be when?

Main Sequence; 5 billion years
Protostar; 5 billion years
Main Sequence; 2 billion years
Red Giant; 5 billion years
Our sun is currently in its main sequence phase. Astronomers estimate that nuclear fusion will burn all of the hydrogen in its core and it will begin its next phase of life, which will be the red giant phase, in approximately 5 billion years.
The red supergiant, Betelgeuse (yes…pronounced “Beetle Juice”) is the 2nd brightest star in the constellation Orion. Due to its size and gravity, it is responsible for creating some of the heavier metals in the universe. What is a heavier element likely created by Betelgeuse?
*
1 point
Hydrogen (H)
Silicon (Si)
Helium (He)
Lithium (Li)
A heavier element likely created by Betelgeuse is Silicon (Si).
