Transient lunar phenomena (TLP) are relatively brief flashes of light that appear to come from the surface of the Moon. Such flashes of light have been observed for centuries by both amateur and professional astronomers, and several theories have been put forward to explain them.
One theory is that TLP are not genuine lunar phenomena, but only random observational errors caused by defects in the telescopes some observers use. Optical instruments such as telescopes or microscopes are complex pieces of machinery; even small flaws in their design can create artificial optical impressions like flashes or other distortions in the visual field. To an observer, a flash of light caused by an instrument error may sometimes look like a real phenomenon taking place in nature.
A second theory is that meteors striking the Moon cause TLP. Because the Moon has no atmosphere, meteors often reach the lunar surface. In fact, meteors strike the Moon every day. According to the meteor theory, when meteors strike the lunar surface, they explode, creating enough heat energy to appear as a flash of light to observers on Earth. When people observe TLP, they are actually observing flashes of light generated by meteor impacts.
A third theory is that TLP are the result of lunar rocks emitting their own light by a process called thermoluminescence. It is known that the Moon does in fact contain certain rocks that are capable of generating light in this way when they are heated by the Sun. This is strong empirical support that TLP are caused by thermoluminescence.

Doctor Gupta: Ensuring that high school students get the education they need is challenging. Some educators are recognizing that regular classes at school may not be enough to prepare students for careers and for life. Because of this, they recommend that all high school students be required to spend a specific number of hours learning useful skills outside school. Others think that this requirement is not appropriate for all students. Which view do you agree with? why?
Claire: I think high school students should not be reguired to learn skills outside school. Schoolwork is already overwhelming for many, with exams, projects, and extracuriculars. Adding more would create unnecessary stress. Life skills can be learned after graduation when students have more time to focus on personal growth.
Andrew: I believe high school students should be reguired to learn practical skills outside school. Many lack basic skills like cooking or managing money, which can lead to problems later in life. A friend of mine struggled in college because he didn’t know how to budget. lf he had learned these skills earlier, he could have avoided unnecessary stress and debt.
