I helped Professor Dave lay out exactly how Avi Loeb has manufactured doubt and pushed a false narrative about 3I/ATLAS, which is still an interstellar comet. Please enjoy the video and please repost this to share the word.

24 November 1859: 'On the Origin of Species', Charles Darwin's groundbreaking book, was published.
Darwin's magnum opus is considered to be the foundation of evolutionary biology and is undoubtedly one among the most important books in the history of science.

That little whitish puff just above and to the right of the Boogeyman’s head?
That’s the reflection nebula vdB 62.
Inside it hides HBC 515, a baby orange star only a few hundred thousand years old that’s still having violent tantrums (it’s an FU Orionis-type variable).

Here's a fun astrophotography target to try with your telescope this season - but be warned, this one takes TIME!
LDN 1622 is a dark nebula in the constellation Orion that resembles 'a dark figure with a head and arms' (I kinda see it!)

Harvard professor Avi Loeb claims 3I/ATLAS could be an alien spacecraft. Arizona State University professor Steven Desch is sure it isn't.

A new study, led by Marie Barbillon, exploited the spectroscopic parametriser from Gaia DR3 to build a high-resolution extinction map! It extends up to 4 kpc from the Sun, with a finer version focused on the Local Bubble area.

A thread worth reading slowly.
It explains, clearly and straight to the point, why Loeb’s claims about #3I/ATLAS don’t hold up—not a matter of opinion, but of comet physics anyone can check.
The tail isn’t escaping gas, it’s dust pushed by solar radiation.

Avi Loeb's calculations about 3I/ATLAS are 100% wrong because he has never understood that dust in the tail(s) responds to solar radiation pressure. Solar wind shapes the ion tail. But the radiation pressure is about 1000 times larger than the solar wind ram pressure, for particles that feel it.
