Solar System: Things to Know This Week
Mark your calendars for summer 2018: That’s when we’re launching a spacecraft to touch the sun.
In honor of our first-ever mission to the heart of the solar system, this week we’re delving into the life and times of this powerful yellow dwarf star.
1. Meet Parker
Parker Solar Probe, our first mission to go to the sun, is named after Eugene Parker, an American astrophysicist who first theorized that the sun constantly sends out a flow of particles and energy called the solar wind. This historic mission will explore one of the last regions of the solar system to be visited by a spacecraft and help scientists unlock answers to questions they’ve been pondering for more than five decades.
2. Extra SPF, Please
Parker Solar Probe will swoop within 4 million miles of the sun’s surface, facing heat and radiation like no spacecraft before it. The mission will provide new data on solar activity to help us better understand our home star and its activity - information that can improve forecasts of major space-weather events that could impact life on Earth.
3. Majorly Massive
The sun is the center of our solar system and makes up 99.8 percent of the mass of the entire solar system. If the sun were as tall as a typical front door, Earth would be about the size of a nickel.
4. Different Spin
Since the sun is not a solid body, different parts of the sun rotate at different rates. At the equator, the sun spins once about every 25 days, but at its poles the sun rotates once on its axis every 36 Earth days.
5. Can’t Stand on It
The sun is a star and a star doesn’t have a solid surface. Rather, it’s a ball of ionized gas 92.1% hydrogen (H2) and 7.8% helium (He) held together by its own gravity.
6. Center of Attention
The sun isn’t a planet, so it doesn’t have any moons. But, the sun is orbited by eight planets, at least five dwarf planets, tens of thousands of asteroids, and hundreds of thousands to trillions of comets and icy bodies.
7. It’s Hot in There
And we mean really, really hot. The temperature at the sun’s core is about 27 million degrees Fahrenheit. However, its atmosphere, the corona, can reach temperatures of 3 million degrees. (That’s as if it got hotter the farther away you got from a fire, instead of cooler!) Parker Solar Probe will help scientists solve the mystery of why the corona’s temperature is so much higher than the surface.
8. Travel Conditions
The sun influences the entire solar system, so studying it helps us better understand the space weather that our astronauts and spacecraft travel through.
9. Life on the Sun?
Better to admire from afar. Thanks to its hot, energetic mix of gases and plasma, the sun can’t be home to living things. However, we can thank the sun for making life on Earth possible by providing the warmth and energy that supply Earth’s food chain.
10. Chance of a Lifetime
Last but not least, don’t forget that the first total solar eclipse to sweep across the U.S. from coast-to-coast since 1918 is happening on August 21, 2017. Our toolkit has you need to know to about it.

Science that soars
This team of SEAS students developed a NASA flight instrument that will measure the concentrations of stratospheric chemicals that cause ozone depletion over the Midwest United States. Recent research by Jim Anderson, Philip S. Weld Professor of Atmospheric Chemistry, has shown that intense summer storms cause a phenomenon called convective injection, where water vapor is thrust high into the lower stratosphere, interacting with atmospheric chlorine and setting off a chain of chemical reactions leading to a risk of increased ozone depletion. The instrument developed by the students measures stratospheric concentrations of bromine and chlorine, capturing detailed data that will be used to analyze trends in atmospheric conditions and ozone depletion. Plans call for the instrument to be used to conduct research next summer aboard an innovative, solar-powered aircraft that will fly high above the Midwest continuously for three months.
“If we find out that convective injections are actually correlated with ozone depletion, that gives incentives for governments and larger scale organizations to make changes in the way we address these problems, which could spark other innovations in stratospheric chemistry and change how we think about geoengineering,” said Aldís Elfarsdóttir, S.B. ’18, an environmental science and engineering concentrator. “It’s thrilling to know that next summer’s ozone depletion research with our chlorine and bromine radical detection instrument may make a big difference and help us fight anthropogenic global climate change.“

Lack of serotonin has been linked to depression, anxiety, obsessive compulsive disorder and bipolar problems. The bacterium appears to be a natural antidepressant in soil and has no adverse health effects. These antidepressant microbes in soil may be as easy to use as just playing in the dirt.
Most avid gardeners will tell you that their landscape is their “happy place” and the actual physical act of gardening is a stress reducer and mood lifter. The fact that there is some science behind it adds additional credibility to these garden addicts’ claims. The presence of a soil bacteria antidepressant is not a surprise to many of us who have experienced the phenomenon ourselves. Backing it up with science is fascinating, but not shocking, to the happy gardener.
Mycrobacterium antidepressant microbes in soil are also being investigated for improving cognitive function, Crohn’s disease and even rheumatoid arthritis.
Biofoam sheets based on graphene can be laid on top of dirty or salty bodies of water to purify them and make the water safe to drink, scientists in the US have discovered.
The process – the latest awesome example of what wonder material graphene can do – has huge potential as a cheap, electricity-free water purification method for developing nations.
These dual-layer biofoam sheets work by drawing up water from underneath and then causing it to evaporate in the uppermost layer, releasing fresh water as condensation on the top and leaving particles and salts stuck in the foam.

Biodegradable plastic water bottles and shopping bags are a false solution to the ubiquitous problem of litter in the oceans, the UN’s top environmental scientist has warned.
Most plastic is extremely durable, leading to large plastic debris and “microplastics” to spread via currents to oceans from the Arctic to the Antarctic, a UN report published on Monday found.
Greener plastics that breakdown in the environment have been marketed as a sustainable alternative that could reduce the vast amount of plastic waste that ends up in the sea after being dumped. But Jacqueline McGlade, chief scientist at the UN Environment Programme, told the Guardian that these biodegradable plastics were not a simple solution.
“It’s well-intentioned but wrong. A lot of plastics labelled biodegradable, like shopping bags, will only break down in temperatures of 50C and that is not the ocean. They are also not buoyant, so they’re going to sink, so they’re not going to be exposed to UV and break down,” she said.
Dai Haifei is a Chinese architect. He works for a company whose slogan is “Our Buildings Are Eggs Laid by City,” and apparently nothing was lost in translation there – seeing as how Dai now lives in an egg-shaped house small enough to fit on the sidewalk.
He built this pod on a bamboo frame insulated with wood chips, with bags of sprouting grass on the outside. Total Cost: $964. Though quite small, the pod is big enough to house a bed, a water tank, a night table and a crushing sense of claustrophobia. Dai says he typically works at his architectural firm until midnight and only uses his home for sleep anyway, allowing him to save a ton of money that he can hopefully use one day to escape that incredibly sad-sounding existence.
