New Planets Could Support Life

Earth and Space Science Space Systems

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.

Nepal Earthquake a Year Later

Politics Earth and Space Science

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.

Space Sleepover

Earth and Space Science Space Systems

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.

Pollution from Industrial Revolution Thought to Melt Glaciers

Earth and Space Science Climate Change Human Impacts

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.

A Year in Space

Earth and Space Science Space Systems

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.

Space Waves

Earth and Space Science Sound

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.

The MoonArk is a time capsule that will be sent to the moon on a privately-funded Moon mission. It is filled with items that will attempt to communicate to whomever finds it and show a portrait of humanity. Two hundred artists and designers contributed to the capsule and the items are unique, including a spritz of perfume, sculptures so small you need a microscope to see them and text messages.

Walking in Space

Earth and Space Science Elementary Atmosphere

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.

Oklahoma Earthquakes

Earth and Space Science Environment

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.

Two Kinds of Earthquakes

Earth and Space Science Physical Science

One of the biggest earthquakes ever recorded struck recently, with minimal damage, no tsunami and it barely made the news. That’s because there are two kinds of earthquakes. This earthquake happened when two tectonic plates moved past each other horizontally, while more damaging earthquakes are caused when one plate slips beneath another. This radio story explains the two types of earthquakes and how they are gradually redefining the boundaries of the tectonic plates.

Water on Mars

Earth and Space Science Space Systems

NASA's Mars Reconnaissance Orbiter shows dark streaks flowing down Martian slopes. When the streaks are widest, there is evidence of water molecules. When the streaks shrink in the cold, water disappears. The water is not the same as a stream on Earth, but more like a hint of wetness. Although scientists are not entirely sure where the water source is, they say it could be from a salty underground reservoir or soaking up moisture from the atmosphere. Listen to hear how water can be important for future explorations on Mars.

Earth and Space Science Weather and Climate

It’s been 10 years since Hurricane Katrina flooded New Orleans. At the time, President George W. Bush and his administration were widely criticized for their slow response to the flooding. But on the 10 year anniversary, Bush was invited back to visit the city again. His tour sparked mixed reactions from residents who still feel they were let down by the federal government's response to the massive disaster.

The History of a Former Slave

Race Earth and Space Science Slavery Geology

Historically slaves in the United States are depicted as uneducated farm hands on plantations in the South. But that wasn’t true for all slaves. One famous slave named Yarrow Mamout was an educated Muslim who earned his freedom and even had his portrait painted by a famous American painter. He was a entrepreneur, money-lender and stock-owner, as well as having a reputation for being honest and moral. Archaeologists are trying to find out more about Yarrow Mamout by excavating a plot of land in Georgetown where he owned a home from 1796 until his death in 1823. Listen to this story to learn why this former slave is so well-known and respected.

State versus Towns Over Fracking

Civics/Government Earth and Space Science Environment

The practice of fracking, extracting gas from deep inside the earth, has divided neighbors and split towns. And now it’s pitting cities and towns in Texas against the state of Texas. The Texas state legislature has passed a law that takes the power to regulate the gas industry away from the cities and towns directly impacted by fracking. As you'll hear in this public radio story, blocking these local efforts to control fracking has sparked a fierce debate.
