The <u>innermost core</u> is the immovable object in a supernova explosion.
<h3>
What is Supernova?</h3>
- The enormous and dazzling explosion of a star is known as a supernova.
- This sporadic astronomical event occurs either when a white dwarf is sent off into uncontrollable nuclear fusion or in the latter stages of the formation of a massive star.
- The initial object referred to as the progenitor either entirely vaporizes or falls into a neutron star or black hole.
- A supernova's peak optical luminosity can be comparable to that of an entire galaxy before diminishing over the course of a few weeks or months.
- The most recent supernova remains have been found, although Kepler's Supernova, which happened in 1604, was the last one in the Milky Way that could be directly observed.

Answer: A - P.M. Grootes, K.M. Cuffey, and J.M. Bolzan, among others.
Explanation: Dr. Anandakrishnan collaborated and coauthored with all of the people listed above and has worked with many other people.
During the year 1994, Dr. Sridhar Anandakrishnan collaborated with Kurt M Cuffey, Richard B Alley, Pieter M Grootes and John M Bolzan on the topic 'Calibration of the δ18O isotopic paleothermometer for central Greenland, using borehole temperatures'
They calibrated the δ 18O paleo-thermometer for central Greenland using borehole temperatures, a thermal model forced by a measured δ 18O record and a formal inverse technique. The calibration is determined mostly by temperature fluctuations of the last several centuries, including the Little Ice Age.
Results are generally insensitive to model variables, including initial condition, basal boundary condition, parameterization of snow thermal properties, ice thickness and likely errors in temperature and isotope measurements. Results of this borehole calibration also seem to be in agreement with modern spatial gradients of δ 18O and temperature.
They suggest that calibrations of isotopic paleothermometers using borehole temperatures are a useful paleoclimate tool because they are independent of spatial gradients and include the effects of prehistoric temperatures.
Answer:
C.
Explain:
The phases on the moon are angels that we see from the sun shining down on it. Every night it changes because of the Moon and Earth rotating around the sun.
