Just seeing one is considered to be good luck. Some cultures believe that fallen souls believe that shooting stars represent souls that have been released from purgatory, allowing them to finally go up to heaven and be at peace.
In other cultures, a shooting star is the soul of a new baby coming to Earth to be born. No matter what you have known before, a shooting star is the symbol of positivity. If you are unsure about anything or you have a pending decision, then seeing a shooting star is the signal.
It means that whatever you are about to do, you will find good in it. You should go ahead as it is the signal from the spirits. For years, the seismometers recorded all manner of tremors and jolts, including almost moonquakes, meteoroid strikes, and 9 spacecraft deliberately crashed into the Moon. All these data were transmitted to Earth for analysis. Above: Buzz Aldrin deploys a seismometer in the Sea of Tranquillity. There are thousands of tremors caused by We do. Critical to the analysis are nine man-made impacts.
Above: A seismic waveform recorded when Apollo 12's lunar ascent module crashed into the Moon on Nov. Also, in , a 1, kg 2, lb asteroid hit the Moon just north of Mare Nubium, the Sea of Clouds. It was a major impact recorded at all four seismic stations. Cooke and Diekmann will hunt for impacts in the Apollo seismic records using these known waveforms as a reference.
In theory, they should be able to pick out tremors from objects as small as 10 centimeters 4 inches , weighing as little as 1 kg 2. According to the Standard Model, such meteoroids hit the Moon approximately times a year—more than once a day. Picture a map of Africa stuck with pushpins. The Apollo seismic dataset can test that prediction and many others. The analysis is just beginning.
In this weekly series, Life's Little Mysteries provides expert answers to challenging questions. The sky is falling! No, really: imagine if Earth's atmosphere collapsed. What would happen if all those molecules bobbing around above our heads suddenly nosedived? Paradoxically, this is no airy affair. All the oxygen, nitrogen and other stuff in Earth's atmosphere has a whopping combined mass of 5 quadrillion tons, so a falling sky would mean that nearly 10 tons of molecules — roughly the heft of a school bus — would drop on every square meter of Earth's surface.
Pancakes, everyone? To keep things interesting, let's envision a less "crushing" scenario: What if the atmosphere suddenly disappeared — if an exceedingly rare quantum fluctuation caused all the atmospheric particles to unexpectedly jump to the other side of the galaxy, leaving Earth floating in a vacuum? Vaclav Smil, distinguished professor in the faculty of environment at the University of Manitoba in Canada, said three things would kill us: oxygen deprivation, a severe drop in temperature, and exposure to a full dose of UV radiation from the sun, most of which the atmosphere currently blocks.
