Here is what we know now..
The Manhattan-sized interstellar object 3I/ATLAS exhibited signs of non-gravitational acceleration and appeared “bluer than the Sun” as it passed our local star — which could be signs of an alien craft “engine,” according to Harvard astrophysicist Avi Loeb.
The object’s non-gravitational acceleration was recorded by NASA this week and indicated a dramatic outgassing which would be expected from a comet — and would mean the object would lose half its mass and exhibit a huge plume of debris in the coming months.
And here is what professor Avi Loeb had to say..
Loab keeps making the scientific community a bit nervous openly discussing just how weird this comet is. Whether it is an alien on a ship or just something we have never experienced before –maybe new elements not on our periodic table!– it is exciting and really admirable that he was able to put this comet into the lexicon of our lives…
SPACE.COM has a more conservative approach to the blue light special:
“The reason for 3I’s rapid brightening, which far exceeds the brightening rate of most Oort cloud comets at similar r [radial distance], remains unclear,” the scientists behind the research, Qicheng Zhang of Lowell Observatory in Flagstaff, Arizona, and Karl Battams, an astrophysicist at the Naval Research Laboratory (NRL) in Washington DC, write in a paper discussing the observation published on the research repository site arXiv.
The rapid brightening of 3I/ATLAS was observed by STEREO-A and STEREO-B, the twin spacecraft that make up Solar Terrestrial Relations Observatory (STEREO), by the sun observing Solar and Heliospheric Observatory (SOHO), and the weather satellite GOES-19. The space-based observations were necessary because ground-based instruments won’t be able to observe the interstellar comet again until it passes out from the other side of the sun into its “postperihelion” phase, escaping the glare of starlight in mid- to late-November 2025.
Some have become worried about a path change..,
And at least one person in government says she wants NASA to reveal more.. a letter from Rep Ana Paulina Luna goes public:
