A syzygy feels magical, and not just because it gets you at least 25 points in Scrabble. The whole concept of celestial bodies aligning feels poetic. When it results in a total solar eclipse here on Earth, you can feel for a few moments as though you're part of something much greater and grander than yourself. The transience only makes it more beautiful. Which is why thousands of people will flock to the path of totality on August 21, 2017: to witness a once-in-a-lifetime phenomenon.
You know that thing where Australians don't want nuclear reactors built in our own backyard? Yeah, China doesn't have that. It's well on its way to becoming a world leader in nuclear power; its 37 reactors are already producing 32.4 gigawatts of electricity, and more than 20 more reactors are currently under construction
The shivers, the shakes, the chills—we've all experienced a fever at one time or another. When we take our temperatures and the thermometer reads anything above 99 degrees, many of us immediately believe we are afflicted with some kind of infectious microbe. But, in fact, having a fever doesn't always signal infection. Yes, contagions like strep throat or the flu, are the most common reason for an elevated temperature, but it's surely not the only one. More uncommon ailments like brain injury, reactions to legal and illegal drugs, and even cancer can raise your body temperature above its natural level. But don't freak out, yet. Knowing what the causes are and how they can occur can help you make the most informed decision about your elevated body temperature.
Imagine. You are an ancient human and your reliable and faithful sun suddenly and unexpectedly goes dark. This terrifies you. You think, 'What if it never comes back? Oh gods, WHAT HAVE WE DONE TO DESER...oh, it's back. Phew.' But then, over the years, it keeps happening. You begin to lose trust in the sun's loyalty and start recording when these events happen. Centuries go by and eventually enough of a pattern has built up that early civilizations are able to predict when these crazy events might occur.
When the sun disappears behind the moon on Monday, scientists will be ready. The astrophysics of the eclipse are known, so for space watchers it will be a time to relax and partake in the strange beauty of day gone suddenly dark. For the atmospheric scientist however, the eclipse provides a shining opportunity to directly study how the sun influences weather patterns by heating the atmosphere. To that end, a team of researchers from Oklahoma State University and the University of Nebraska is going to spend Monday tracking changes in the atmosphere in the path of the eclipse. And to get just how the eclipse changes the weather in the low sky, the team will fly drones during the totality.
Our galaxy, the Milky Way, is a barred-spiral, making its way through space like a twirling baton with streamers on each end, carefree. It's a shape that we all know and love. Nothing wrong with that, barred spirals are great. But other galactic shapes are far more mysterious and intriguing to astronomers.
