There is no natural hole to the center of the planet Earth, so seeing what is in the center is difficult. University of Miami professor Ta-Shana Taylor talks about what is deep into the center of the Earth. Scientists haven’t ever drilled deeper than 2,000 feet into the Earth’s crust. Seismographs are used to measure earthquakes, which send waves of motion through the earth’s crust. Listen to hear about how scientists have tried to discover what is in the center of our planet.

During the space race between the United States and Russia, many of the NASA mathematicians who made space flight possible were women. Moreover, many of these important scientists were black women, which is significant, because segregation was still in full effect. Although white male engineers and astronauts have been the most highlighted in history, people are now celebrating the essential contributions of these female, African-American scientists, including the movie “Hidden Figures.” Listen to learn more about the black female scientists like Katherine Johnson and their important contributions to space travel.

Dark matter is invisible and barely interacts with anything else. Finding dark matter and proving it exists is a difficult task. There are a few theories about what dark matter is but no one has found a way to detect it. It could be that the universe is mostly invisible. Listen to hear more about dark matter and what it can tell us.

Astronomers have noticed blobs of eerie light glowing in outer space and have been puzzled by them since their discovery. Astronomers were studying galaxies in the distant universe, when they noticed strange glowing clouds of gas that were 10 times the diameter of the Milky Way. They have been looking into the source of light coming from the blobs and have recently made an interesting discovery that reveals why the blobs produce a glow.

Scientists have discovered evidence of gravitational waves, which show ripples in space and time. A new machine has made it possible for scientists to observe space in a whole new way. Recently, the machine picked up vibrations from the collision of two black holes. The discovery comes a few months after the very first detection of gravitational waves. With these tools, scientists can look at the universe in a new way. In this story you will hear the signal from the black holes converted from gravitational waves to soundwave.

NASA is preparing to launch a spacecraft that will measure and report space weather and provide live images of Earth. The idea to provide Earth’s images for the public to view started with former Vice President, Al Gore, in 1992. He believed everyone should be able to view and study the earth. The satellite’s ability to measure space weather will help prevent against damaging effects on earth from things like solar storms that can damage electric power grids. After more than a decade, Gore’s vision is becoming a reality. Listen to hear more about this new satellite.

Scientists recently made an exciting discovery. They spotted three, earth-sized planets beyond our solar system. Though scientists have found many planets in the past, these particular ones are special because they may potentially support life. They each orbit a reddish “dwarf star” that is smaller than our sun and much cooler. Scientists used to ignore these dwarf stars, but now we know that such stars can produce planets worth studying. Scientists will continue to analyze these planets to find out more about their atmospheres and properties. Listen to hear more about these three newly-discovered worlds.

The Himalayan country of Nepal was rocked by a devastating earthquake that killed almost 9,000 people one year ago. Today, the country still suffers from widespread homelessness, power outages and a serious lack of basic supplies. Even with the large amounts of money pledged to Nepal, none of that money actually arrived to help the people. Monsoon season is approaching and the people need more secure living situations in order to survive. Listen to hear more about the conditions in Nepal after the earthquake.

Astronauts live and work in small spaces. If they were to stay in space for years at a time, they would need a larger place to live. The problem has been how to pack something large into a small space capsule. The solution may be an inflatable room. NASA is now ready to test a new inflatable habitat. It will be sent to the International Space Station for a trial. Listen to hear more about this invention.

The glaciers in the European Alps started melting rapidly in the 1860s. But that didn’t correspond with the warming of the European climate at the end of what is known as the Little Ice Age. That warming didn’t occur until the 1910s. To understand the causes of the glacial melt, scientists considered the possible impact of the Industrial Revolution, which began in the 1840s. The recent melting in the Rocky Mountains of America could be caused by the same reasons. Listen to this story to learn about the theory that dust and soot are contributing to how quickly glaciers are melting.

After living in space for almost a year, NASA astronaut Scott Kelly returned safely to Earth. Kelly stayed aboard the International Space Station, conducting experiments and taking photographs of Earth. Throughout the year, he was able to communicate with people at NASA and update them on his activities and status. Researchers at NASA have also tracked Kelly’s physical and mental health after one of the longest missions in space. Listen to the story to hear more about this astronaut’s admirable and historic journey.

Scientists recently announced a huge discovery—gravitational waves. The waves were detected when a collision of two black holes created ripples or waves, similar to ripples on a pond. These ripples were predicted by Albert Einstein a century ago as a part of his theory of relativity. Scientists have been working to detect these waves for decades and are excited about the information that can be learned from them. In this story you will hear what gravitational waves sound like and learn more about their discovery.

There are only a small number of people who have been in space. A smaller number of people have been outside a space station, tied only with a tether, floating in space. There is a huge amount of training and planning that goes into a space mission, but sometimes things still go wrong. Now astronauts have fewer opportunities for space travel since NASA ended its shuttle program in 2011. Listen to these astronauts as they describe their experiences floating over the Earth.
Current Event December 9, 2015
Oklahoma has experienced more than 5,000 earthquakes this year. Some scientists tie these earthquakes to fracking, the extraction of oil and gas from deep within the earth. Fracking uses water to extract the oil and gas and is then injected into underground wells for storage. This can put pressure on faults and cause them to slip and trigger an earthquake. After inspections were ordered, state regulators shut down the water disposal wells, which slowed the earthquakes. But once the wells came back online the earthquakes started again. Listen to hear more about how oil is related to earthquakes in Oklahoma.
