NBC News· 2025-10-03 02:46
Tonight on the future of everything, we've got three eye atlas updates and maybe even our best shot yet to clearly see the third interstellar object ever detected passing through our solar system. But let's just rewind real fast for a second here because this thing has been on our radar only for about uh a few months since then. Things have gotten very very interesting.According to astronomers, three Atlas has all kinds of surprises. We've only seen a handful of of blurry shots that look like a tail is kind ...

Interstellar Object Threeey Atlas Analysis - Observation of Threeey Atlas, the third interstellar object, is underway, with real-time streaming of telescope images [1] - The object is considered a building block from another star system, sparking scientific interest [1][2] - The object's tail development is under close observation, though its nature remains uncertain [2] Trajectory and Observation - Threeey Atlas will pass by Mars around October 3rd, offering NASA's Mars Reconnaissance Orbiter a prime viewing opportunity [3] - The Mars Reconnaissance Orbiter's camera could potentially resolve the object with a pixel size of 30 kilometers, providing crucial data [8] - Earth-based observation windows are closing due to the sun's glare, making the Mars flyby critical [2][9] Object Characteristics and Composition - Initial estimates suggested a size of 20 to 40 kilometers in diameter, comparable to a city like San Francisco [4] - The object's nature is debated: it could be a solid object or a dense cloud of dust [5] - Unusual behavior, such as a glow ahead of the object and a teardrop-shaped plume, is being investigated [10] - The object's plume is primarily carbon dioxide (95% by mass) with only 5% water vapor, based on web telescope data [12] - Recent data indicates the presence of nickel without iron, a combination typically associated with industrial production [12] Scientific Debate and Classification - The object's classification is uncertain, with possibilities ranging from a natural object to a technological one [14] - One astronomer uses a "Lobe scale" to rank the object, currently placing it at four out of ten, leaning towards natural but with open questions [14]

There's a mysterious interstellar object hurtling towards our solar system, exciting scientists across the globe. While many think it's just a comet, some theorizing a possible alien origin due to a few curious characteristics. The peculiar thing about it is that it's moving along a trajectory that is very special.Harvard physicist Avi Loe has been tracking the object named threeey atlas. when it arrives closest to the sun, the earth would be on the opposite side and we won't be able to observe it. But that ...
