First-Known Boomerang Meteorite? This Space Rock Might Have Come From… Earth

Scientists Seem to Have Discovered a Meteorite That Came from Earth

A group of scientists have recently discovered a meteorite that offered a surprise to everybody. While it may resemble a typical meteorite, this one has a peculiar chemical composition that’s strikingly similar to that of rocks found deep within the Earth’s oceans. Considering this find, scientists think the meteorite may have originated on Earth.

A Meteorite from Earth

The meteorite may have been ejected into space from Earth in some cosmic event, and in time, it found its way back home. It was discovered in the Maghreb region in 2018 and called Northwest Africa 13188. It weighs nearly 23 ounces, and its chemical makeup mainly consists of the minerals plagioclase and pyroxene, making up one-third of the rock. To gain more knowledge about the meteorite, scientists have studied the isotopic composition of the rock, particularly focusing on oxygen.

By analyzing the ratios of oxygen isotopes, researchers can discern the origin of a celestial body. In the case of the meteorite, the oxygen isotope ratios and the rock’s mineral components suggest that Earth was its place of origin. Upon closer examination of the rock’s well-developed fusion crust, it was revealed that the concentrations of isotopes of beryllium, helium, and neon are consistent with those that would result from exposure to cosmic rays over about 10,000 years. This evidence allowed scientists to assert that Northwest Africa 13188 was a meteorite that was initially launched from Earth and later re-accreted to its surface.

The Meteorite Is 10,000 Years Old

According to the definition, an object is a meteorite if it originates from a celestial body and attains an independent orbit around another celestial body, including the sun, and eventually returns to its point of origin. While getting proof for such a complex series of events is a challenge, the presence of terrestrial rock that was exposed to cosmic rays makes this case plausible.

Eager to learn more about the full story of this peculiar meteorite, researchers are conducting further isotopic analyses in hopes to shed light on how it escaped Earth’s gravity confines.

Emily Blunt Will Leave a Set if She Reads Three Specific Words

Emily Blunt is a popular British actress and a recipient of multiple accolades, such as a Golden Globe Award and a Screen Actors Guild Award. And that’s all in addition to the three nominations she’s received from the British Academy Film Awards. We can watch her incredible acting skills in many films, such as The Devil Wears Prada and A Quiet Place.

Emily Blunt Will Leave the Set if She Reads Three Specific WordsThe Actress Leaves Immediately

Emily Blunt has plenty of movies tucked under her belt, and we don’t doubt she’ll have many more such as The Girl on the Train or Young Victoria, and she probably enjoyed playing those roles as much as we enjoyed watching the production. But she says that if she happens to read the three specific words – strong female lead – she simply wants to call it quits!

Emily Blunt Gets Bored

When the actress reads that specific phrase in a script, she knows it’s time to be ‘out’ of the production. She explains that such a phrase means the female lead will be boring and quiet – she prefers more interesting roles. According to the 39-year-old, when a lead is supposed to be strong, she is expected to have almost no emotion, and she prefers a character with a secret – someone with buoyancy and more complex emotions.

Others Are Fans of Labels

Emily opens up about her brother-in-law, another famous actor – Stanley Tucci. She shares that while he was shocked to receive a racy label because of an Instagram video of him making a drink – he also quite enjoyed it. He even agreed and said, “I mean, yeah!” So, she may not be happy with receiving labels on scrips, but others certainly are.

Although hard to believe, actors and actresses have nit-picky qualities when selecting the scripts they read and the movie roles they take on. Some, like our lovely Emily Blunt, look for specific words that trigger them and make them not want the part. To each their own!
