Part A
1. Mary A. Voytek works at NASA and she studies environmental controls on microbial transformations of nutrients, xenobiotics, and metals in freshwater and marine systems.
2. She is a reliable because she is in charge of NASA's Astrobiology program
3. I read an interview online about a week ago from people asking questions all over the world

Part B
1. All of my friends at school are telling me that we are all going to die in the year 2012 due to a meteor hitting earth. Is it true?

Your friends are wrong. The Earth has always been subject to impacts by comets and asteroids, although big hits are very rare. The last big impact was 65 million years ago, and that led to the extinction of the dinosaurs. Today NASA astronomers are carrying out a survey called the Spaceguard Survey to find any large near-Earth asteroids long before they hit. We have already determined that there are no threatening asteroids as large as the one that killed the dinosaurs.

2. Why does the Mayan calendar say the world will end in 2012? I have heard that they have been pretty accurate in the past with other planetary predictions. How can you be sure you know more than they did?

Calendars exist for keeping track of the passage of time, not for predicting the future. The Mayan astronomers were clever, and they developed a very complex calendar. Ancient calendars are interesting to historians, but they cannot match the ability we have today to keep track of time, or the precision of the calendars currently in use. The main point, however, is that calendars, whether contemporary or ancient, cannot predict the future of our planet or warn of things to happen on a specific date such as 2012. To further complicate matters, scholars do not agree on when the Mayan calendar long-count turns over.

3.  There are many photos and videos of Nibiru on the Internet. Isn’t that proof that it exists?

Many of the photos and videos on the Internet that were taken two or three years ago were of some feature near the Sun (apparently supporting the claim that Nibiru was hiding behind the Sun). These are actually false images of the Sun caused by internal reflections in the lens, often called lens flare. You can identify them easily by the fact that they appear diametrically opposite the real solar image, as if reflected across the center of the image.
