On July 16, 2024, a meteorite landed in a house in New Jersey. Analysis of the fragments of this meteorite revealed signs of saltwater and organic molecules originating from a primitive asteroid.
In the 'Olhar Espacial' column today, Marcelo Zurita explains in detail the significance of this recent scientific discovery.
A space object crossed the sky over New York in 2024 and landed inside a house located in New Jersey, providing a unique scientific opportunity. Analysis of the recovered fragments revealed traces of saltwater and organic molecules originating from a primitive asteroid.
On July 16, 2024, residents of New York, New Jersey, and other American states spotted a meteor during the day. The passage of the celestial body was marked by a loud noise as it penetrated the atmosphere at approximately 14.4 kilometers per second. Researchers were able to trace its trajectory using cameras from the American Meteor Society, resident reports, and a doorbell camera, indicating that its origin was linked to the asteroid belt.
A forensic examination of the pieces showed that they contained preserved material near the surface of a primary asteroid, where reactions occurred with concentrated saline fluids—a phenomenon unprecedented in this type of protoplanetary world. Due to the rock's fragility, it partially disintegrated during atmospheric entry. After becoming invisible, a local weather radar located a cloud of small debris between Staten Island and New Jersey, with Hillsborough receiving one of the largest recovered portions.
The owner of the hit house noticed a hole in the bedroom ceiling, scattered dark fragments, and a sulfur-like odor. He acted quickly, collecting the material with disposable gloves and aluminum foil, packaging the pieces in glass containers, which kept the sample in exceptional condition for analysis. Scientists classified the material as a carbonaceous chondrite CM1/2, an intermediate category between CM1 and CM2.
The fall in Hillsborough is the second occurrence of this type recorded by science. The findings included small salt-rich fragments, suggesting they came from a surface area of the asteroid where water had evaporated and concentrated minerals. Researchers identified several soluble organic compounds, such as amino acids, along with evidence of water-induced modifications.
The discoveries include the presence of 1.8% carbon by weight in the meteorite, 0.07% nitrogen, organic compounds similar to those found in other primitive meteorites, and signs of chemical interactions influenced by saline fluids. Phil Schmitt-Kopplin, an expert in organic mass spectrometry from the Technical University of Munich, commented that a high proportion of the compounds resulted from organic chemistry interacting with minerals. According to experts, such processes may have helped conserve molecules crucial to the chemistry preceding the emergence of life.
Part of the fragments will be kept at the American Museum of Natural History in New York. Denton Ebel, curator of the institution, expressed enthusiasm about the arrival of such an asteroid sample. This event demonstrates how an accidental impact on a residence can expose details of a distant past, recorded in materials formed in the early stages of the Solar System.
The Monday edition of Olhar Digital News presents various significant events. Scientists have discovered the first sugar in space, indicating a potentially more chemically rich cosmic environment. Furthermore, a group of over 200 researchers and economists has strongly urged the urgent creation of policy measures to counteract the economic consequences of artificial intelligence.
Experts believe that the expansion of AI's scope could trigger economic transformations comparable to the Industrial Revolution, but this will happen in a significantly shorter adaptation period. This poses serious challenges for workers, corporations, and government bodies.
The Waze application has introduced several new features. These include a dedicated mode for motorcyclists, personalized navigation capabilities, and new tools based on Gemini, Google's artificial intelligence. The company stated that these improvements aim to tailor the navigation experience to individual user preferences and expand voice interaction capabilities.
The US government continues to release archival materials concerning UFOs while advancing its investigation work. For this purpose, Harvard astrophysicist Avi Loeb was appointed as the head of a council tasked with preparing scientific reports and providing recommendations on deciphering the nature of these mysterious phenomena. The astrophysicist himself has drawn public attention due to repeated claims of finding evidence of extraterrestrial technology.
The US Federal Aviation Administration has granted SpaceX permission to conduct a new launch of the Starship version V3 rocket, considered the most powerful in the world. Previously, tests were suspended following an engine failure in the Super Heavy during the first flight of this new modification in May of this year. After receiving approval, the company, led by Elon Musk, set the next launch date for July 16th, Thursday.
