The Closest Black Hole to Earth is just 1,500 light-years Away

by Emily Rodriguez Lima, age 13

There are plenty of black holes in outer space. Astronomers have found what they believe is currently the closest black hole to Earth.

Gaia BH1 is about 1,560 light-years from Earth and has a mass 10 times bigger than that of the sun. It is the first black hole discovered to be close to Earth, the second closest is around twice the distance at 3,200 light-years away.

Like many black holes, Gaia BH1 eats gas from massive stars that are clustered together. As the black hole eats the gas, it forms a disk around the black hole that can only be seen through x-rays. A star that is orbiting a black hole at a safe distance will not get eaten, but since the gravitational pull of a black hole is massive it can get pushed and pulled around space. [Read More]

Greenland’s Frozen Hinterlands are Melting Faster than Expected

by Theodore B. Morrison, age 15

Climate change has been impacting the planet for ages since humans started producing greenhouse gases. One impact climate change has had is the melting of the glaciers, which scientists have been trying to track for some time. One group has been following a particular ice stream to help keep track of the effects of climate change.

This group used GPS to track ice stream movements. The furthest point inland observed by this group transitioned from approximately 344 meters a year to 351 meters a year in three years. The quick movement of ice streams is projected to raise the global sea level by 14 to 16 millimeters by 2100. That is the same quantity of increase in global sea level rise by Greenland’s entire ice sheet in the last 50 years.

The tracking of this specific stream was motivated by the hope of discovering more about the effects of climate change. These sea level rises could change the world's coastlines and many scientists and climate activists hope to attempt to reverse or stop these effects of climate change on a warming planet Earth.

2.5-Yard Elephant Tusk Fossil Discovered in Israel

Researchers in Israel recently found a 2.5-yard-long fossil that belonged to a long-extinct straight-tusked elephant. It is believed to be the largest fossil ever found at a prehistoric site in the country.

This amazing fossil was discovered near a piece of land called a kibbutz on the central plain running parallel to the Israel’s Mediterranean coast. The discovery was made by researchers from Israel Antiquites Authority (IAA) in a joint excavation from Tel Aviv University and Ben-Gurion University. Avi Levy, lead researcher of the find, called this fossil, “The largest complete fossil tusk ever found at a prehistoric site in Israel or the Near East.” This site is at least 500,000 years old based on the stone tools recovered from the area, the antiquites authorities said.

“Very puzzling, very enigmatic,” said Omry Barzilai, an IAA archaeologist also in the discovery, because it was not known whether ancient people hunted the behemoth on the spot or they brought the animal’s tusk to this spot. [Read More]

Study Reveals COVID-19 Pandemic Prematurely Aged Teen Brains

by Ayelen Flores Ruiz, age 13

New MRI brain scans show that teen brains have matured beyond the years of their physical age (as much as three to four years) after the Covid-19 pandemic. This shows the importance of this time for teens’ brain development.

Scientists studying this topic were working on teen mental health before the pandemic hit, so they already had some ideas on what could have affected teens before and after. Researchers revealed that the pandemic was hard on teens, increasing anxiety and depression and prompting scientists to look at the changes that were being made to the brain.

Scientists took MRI scans from 64 teens after the pandemic. They compared the scans to different groups from before the pandemic, matched by their age and sex. The after-effects were the thickening of the hippocampus and amygdala, and the thinning of the cerebral cortex. All of these are a process of maturing for teens. This process usually takes time, but it was determined that the brain matured three to four years beyond their actual age. [Read More]

What's So Special About Earth?

by Ian Kosharek, age 10

Earth is a planet consisting of many essential layers and interesting features. These unique aspects of Earth make it a foundation for life and allow for the survival of species on the planet.

Earth is made of four distinct layers: the outer crust, inner crust, outer core, and the core. The outer crust is made up of rock and dirt and is the layer humans live on. The inner crust is the mantle which is made out of thick rock. Just beneath the mantle is the outer core. This region consists of hot iron and is responsible for lava that sometimes erupts out of volcanoes. The innermost layer is the core which contains the same elements as the outer core.

Outside of Earth, the planet also has relationships with the moon! The moon orbits Earth and if you take a close look, on clear nights you can see the moon change! The moon changes based on the positioning of reflections from the sun. On Earth, a full moon is only visible when the sunlit side of the moon faces Earth. Additionally, did you know that the tides and waves on Earth are created from gravitational pulls from the moon? [Read More]

Local Observatory Renamed For STEM Pioneer Jocelyn Bell Burnell

by Mariah Justice, age 17

“Astronomy compels the soul to look upward, and leads us from this world to another,” said Greek philosopher Plato. With the renaming event on September 7 for the Bell Burnell Observatory— previously the Oscar Mayer Observatory—Madison has a new facility for cultivating the exploration of astronomy.

The history of the Bell Burnell Observatory dates back to 1880, when the director of the Washburn Observatory, located on University of Wisconsin-Madison's (UW) campus, felt there was too much student traffic for the University to only have one observatory. This notion spurred him to personally fund the construction of the student observatory, which was then called the Student Observatory. However, as Madison grew, light pollution obstructed both the Student and Washburn observatories, rendering the facilities obsolete.

In 1959, the UW offered to gift the Student Observatory to the Madison Astronomical Society (MAS) on the condition that MAS was able to finance a move to a different site. A year later, the observatory was officially relocated to its current location on the Promega Campus, and renamed the Oscar Mayer Observatory after the astronomer who funded its move. The observatory was in use for over two decades until light pollution resulting from Madison’s growth once again caused it to be inactive. [Read More]

Who Created These Mysterious Pillars in Ireland?

by Jonah Smith, age 14

Strange pillars reside in County Antrim, Ireland. They have an unusual shape that appears to be man made. These tightly wedged pillars descend in tiers, in a staircase all the way down to the sea. These columns are mostly hexagonal, though the number of sides these structures have may vary. Although their shape implies that they are manufactured, the complete opposite is true.

There are similar structures such as the Giant’s Causeway in Scotland or Devil’s Tower in Wyoming. With having so many of these unexplained structures around the world, myths for how they were made arose. For the Giant’s Causeway, it is said [locally] that the Irish giant, Finn Mac Cool, drove the columns into the sea one by one so that he could walk to Scotland to fight his rival. These exciting stories theorizing their construction adds new life and attractiveness to these beautiful structures.

The creation of these abnormalities is way more complex than it might seem. During the period where North America and Europe recently split up, the new North Atlantic Ocean in between the two was still a developing feature. The northern area of both Europe and North America was in place, but the body of water still had to form the edges of these continents. The western coast of Greenland separated from Canada around 80 million years ago, but the southwestern coast was still firmly attached to the opposing northwestern coast of the British Isles. 20 million years later, these coasts began to separate and there were major volcanoes in place of a few Scottish islands.

The Mammal that Helped Take Over the Globe

by Ayelen Flores Ruiz, age 12

Researchers have discovered a prehistoric mammal with a two to five years life cycle that they call the Manbearpig. The mammal’s short lifespan is likely due to their months-long pregnancy, a trait scientists believe helped mammals dominate the world after the extinction of the dinosaurs.

The name Manbearpig came from the features it contained: a face like a bear; a body similar to a pig; and five fingered hands. These mammals are also known by their scientific name, Pantolamba bathmodon, and were plant eaters. The Manbearpig lived about 62 million years ago. The Manbearpig was one of the largest mammals of its time and seemed to appear after the dinosaur extinction, which allowed mammals to grow to larger sizes than ever before. It was a member of the placental group of mammals, animals who do their prenatal development in the womb of their mother.

Researchers were able to discover how fast they would grow throughout their life from the enamel of their teeth, which looked different during different life stages. These mammals' lives were short and they died at a younger age than typical animals, between two and five years of life. The Manbearpig had a really short life cycle because it stayed in the womb for about seven months, a pregnancy much longer than is observed in modern marsupials, but similar to extreme modern placentals like giraffes and wildebeests. The most extreme modern placentals are usually walking within hours of birth, and usually only give birth to one baby per litter. This species nursed for one or two months after they were born. In a year, they would reach adulthood. The longest a Manbearpig was found to have lived was 11 years. [Read More]

The Only Canids Known to Fish

by Ayelen Flores Ruiz, age 12

For the first time, researchers observed a fox fishing for food. After seeing the red fox, they joined the group of land mammals that also hunt for fish.

A male red fox was seen fishing in Spain in March 2016. The researchers that captured the moment were Jorge Tobajas and Fransisco Diaz. The fox raised many questions for researchers, such as, are there other foxes that know or have learned to fish by watching other foxes?

When Jorge and Francisco were watching the red fox by the reservoir’s shore, it suddenly went nose first into the water and came out with a large carp. This canid hunted one carp after another and eventually caught ten after a few hours. While hunting, the fox made no mistakes and hid most of his catch but shared carps with a female fox.

Should We Add Insects to Our Diet?

by Emily Rodriguez Lima, age 14

When we think about consuming bugs, most of us would immediately respond by saying, “ew!” Although bugs may look nasty or creepy, they are a good source of protein. If insects are raised and prepared correctly, the protein they carry can be beneficial for our bodies. Raising them requires less water, less land, and overall less resources than other animals.

Though a lot of us did not grow up having insects as part of our meals, scientists have been trying to figure out how to incorporate and make them appealing to humans. Many people throughout the world eat bugs as part of their culture. From ancient times, people have eaten bugs as it was believed it would give you knowledge. A common insect many have tried are crickets. These insects, like many others, are good for your body.

If you are interested in having insects as a small snack, the best option is to do research and buy them at a local grocery store. Do not go to your backyard, garden, or local park and grab them since these insects can contain chemicals and germs that are harmful to the human body. [Read More]

Would You Want to Live on Neptune?

by Dilma Attidekou, age 8

Neptune, the smallest out of all outer planets, is known for its blue color. Methane is the reason for its color. Neptune has less then four percent of methane within its atmosphere.

Neptune is very far from Earth, approximately 2.5 billion miles away. Pluto is usually farther from the sun than Neptune, but once every 248 years, Pluto crosses in front of Neptune. The planet has enormous storms, but they don’t last as long as Jupiter's great Red Spot.

Neptune takes 165 Earth years to orbit around the sun. Due to the planet's orbit being almost a perfect circle, its seasons are all of even length. Neptune’s climate and seasons are different from Earth’s seasons. [Read More]

Native Asian Moth Spotted in Washington State

by Justin Medina Ruiz, age 13

On July 7, 2022, a giant moth with a ten-inch wingspread was discovered in a garage of a home in the state of Washington. Thankfully, the moth species does not pose a public health threat. The Atlas moth originates from the tropical forests of Asia and has not been seen before in the U.S.

It is not clear how this moth found a way to get to Washington. However, scientists found on eBay, an e-commerce company, an account selling Atlas moth cocoons for $60 each. This account was later taken down because the Atlas moth is a quarantine pest, meaning it is illegal to obtain, sell, or harbor, no matter if they are adults, eggs, larvae, or pupae.

In spite of that, the individual sighting does not mean that there is a population of the Atlas in the U.S. The state’s agriculture department asks the public to take photographs and collect Atlas moths if they find one. This would help determine whether there is a population or not. If there were an infestation, it would be harmful to the region’s fruit-growing industry because like other moths and caterpillars, they enjoy feasting on the leaves of cherry and apple trees.

Scientist Watch as Jupiter Comes Close to Planet Earth

by Allison Torres, age 14

Earlier this year, people were able to get a glimpse of Jupiter's rings and moons with only a telescope or binoculars. Jupiter is the largest planet in our solar system and in September it passed closer to Earth than it has in 59 years.

Jupiter is at opposition, meaning Earth is halfway between the planet and the sun, with about 367 million miles between Earth and Jupiter. At its farthest point, Earth and Jupiter are about 600 million miles apart. Patrick Hartigan, a professor of physics and astronomy at Rice University in Houston, said the planet would rise around sunset and look pearly white to the naked eye.

Three to four of Jupiter’s moons could also potentially be seen, one named Europa. Trina L. Ray is a science manager for the Europa Clipper mission at NASA’s Jet Propulsion Laboratory in Pasadena, California. “Since I am working on a spacecraft that we are going to send to the Jupiter system to explore Europa, I'm always excited to see Jupiter and even Europa with my own eyes,” she said. Many scientists were excited to see Europa, as they believe there could be life on Jupiter's moon, according to “The Guardian.” [Read More]

How Submarines Sparked Arctic Exploration

by Daniel Li, age 14

Built in 1952, the USS Nautilus was the first submarine ever powered by a nuclear reactor and, coincidentally, also the first to ever reach the North Pole by traveling under ice. William Anderson, the commander of the Nautilus, wrote in his logbook, “Embarked following personage at North Pole: Santa Claus, affiliation: Christmas.” Spending multiple days underwater had not seemed to affect the commander’s sense of humor.

The Nautilus was 319 feet long and brought 116 crew members to the North Pole. While these numbers are impressive, the defining characteristic of the ship was its nuclear reactor, which eliminated the need for conventional practices such as surfacing or using snorkels to provide air for engines and batteries. All power was provided inside the submarine.

This trip to the North Pole, codenamed “Operation Sunshine,” provided much scientific knowledge that would eventually lead to our current submarines. The Nautilus proved that nuclear-powered submarines were viable, making it possible for modern submarines to spend months at a time underwater. This first voyage was not only beneficial for scientific research, but also for military purposes. Although the United States was the first to develop nuclear-powered submarines, world powers such as Russia and China have developed many of their own. Since 1969, the U.K. has consistently had at least one submarine carrying nuclear weapons at sea. [Read More]
