When our sun reaches the end of its red giant phase, it will turn into a___________?
0
A. Supernova
B. White Dwarf
C. Black Hole
D. Neutron Star
B. White Dwarf
The Sun is currently in its main sequence phase, which means that it is fusing hydrogen into helium in its core. This process releases energy, which keeps the Sun hot and glowing. However, the Sun will eventually run out of hydrogen fuel, and when this happens, it will enter its red giant phase.
During the red giant phase, the Sun will expand to about 100 times its current size. It will also become much cooler, and its color will change from yellow to red. The Sun will remain in its red giant phase for about 1 billion years.
After the red giant phase, the Sun will collapse into a white dwarf. A white dwarf is a very small, dense star that is about the size of Earth. It will continue to cool and dim until it eventually becomes a black dwarf.
The Sun is not massive enough to explode as a supernova or to collapse into a black hole.
What sub-class of neutron star is known for its extremely high magnetic field? 0
A. Magnetar
B. Quasar
C. Magneto
D. Magnetta
A. Magnetar.
A magnetar is a type of neutron star with an extremely powerful magnetic field. The magnetic field of a magnetar is about 1000 times stronger than that of a typical neutron star. Magnetars are thought to be formed when a massive star collapses at the end of its life. The collapse of the star compresses the magnetic field of the star, which causes it to become much stronger.

PSR J0108-1431 is the closest known ______________ to Earth?
0
A. Black hole
B. Red giant
C. Quasar
D. Pulsar
D. Pulsar
PSR J0108-1431 is a pulsar located in the constellation Cetus. It is the closest known pulsar to Earth, at a distance of about 424 light-years. It was discovered in 1994 during the Parkes Southern Pulsar Survey. It is considered a very old pulsar with an estimated age of 166 million years and a rotation period of 0.8 seconds.
A pulsar is a type of neutron star that emits pulses of electromagnetic radiation. The pulses are caused by the rotation of the neutron star, which has a very strong magnetic field. The magnetic field lines are twisted and distorted by the rotation of the star, and this causes the star to emit pulses of radiation.
