Today, we think of Mars as having a cold, dry, and desolate environment (because it does).
But that was not always the case. Four billion years ago, while our Sun was still in its infancy, Mars was covered with water.
Back then, it had a much thicker atmosphere, which kept the planet warm enough for water to exist in its liquid form. Some estimates say that at one point, up to 1640 ft (about half a kilometer) of water covered the whole planet.
Tomorrow will not be your ordinary Friday. For starters, tomorrow is the 13th, making tomorrow a Friday the 13th.
There will also be a full moon in the sky when the clock strikes 12:01 a.m. tomorrow morning. The last time that happened? October 13, 2000. The next time it will happen? August 13, 2049.
I’m not one for superstitions, but there is one thing I haven’t mentioned yet. Our sun has been shooting off powerful solar flares the last few days, including this one captured by NASA’s Solar Dynamics Observatory early Tuesday morning:
Solar flares are brief, high-radiation eruptions that happen on the surface of the Sun. The three flares emitted in the past two days (pictured above) have been X-flares, the most powerful classification of solar flare. X-flares emit radiation at virtually every wavelength, from radio waves, to the light we can see, to x-rays and gamma rays.
Because of all of the different electromagnetic waves that the flares emit, they can disrupt communications here on Earth. In fact, the flare in the video above caused a temporary radio blackout here on Earth, according to Space.com.
Did I mention CMEs? CME stands for coronal mass ejection. This occurs when a powerful solar flare emits a plasma burst along with the radiation. A plasma burst can cause polar geomagnetic storms which are capable of severely disrupting communications and satellite systems, including GPS.
Along with having the potential to cause low levels of radiation poisoning in humans, a strong CME would also create surges in electrical wires, destroying transformers and leaving millions without power.
Despite the scary stuff, CME’s are pretty fascinating. These plasma burst clouds actually compresses Earth’s own magnetic field, which is what causes so many of the potential issues.
At first, officials at the U.S. Space Weather Prediction Center didn’t think that the flare in the video above had emitted a CME, only to find later that it had actually produced two of them.
They are expected to give Earth a glancing blow when they reach Earth orbit…tomorrow, Friday the 13th.
This is an amazing theory by researches, stating that the Fox has nearly a 75% success rate when facing North. It is no doubt that animals contain amazing skills that humans do not possess, but maybe some we do? Maybe we just don’t realize we do, or maybe not? If a canine can tune into the magnetic field of our planet, maybe most animals (including humans) can.
