This is how Atlantic wire scientific columnists roll

AI Thread Summary
The discussion critiques an article about a newly discovered planet, highlighting numerous errors, particularly regarding its distance, which is incorrectly stated as 300 million light years instead of the correct 300 light years. Participants express disbelief at the inaccuracies, noting that the claimed distance exceeds the observable universe's limits. The article's confusion between "image exists" and "discovered via direct imaging" is also mentioned as problematic. Additionally, there is a call for specific examples of the errors, emphasizing the need for clarity in scientific reporting. Overall, the conversation underscores the importance of accuracy in scientific communication.

Apart from the distance, the weird size estimate and the mixture of "image exists <-> discovered via directing imaging", what is so wrong?
I did not check the timescale of direct observations.
 
Well, 300 billion light years...

That distance is 150 times further than the distance to the Andromeda galaxy, and since the observable universe has about a 45 billion light year radius, that distance is very well outside the observable universe.

At that distance, for them to have received the light now, the planet would have needed to emit light from a time older than the universe, but they estimate the planet's star is only 10-17 million years old.
 
Where does the number of 300 billion light years come from? The real value is 300 ly, and the first article has the wrong number of 300 million light years - way too far away for an image of a planet, but at least within the observable universe.
I wonder how such an error gets created.
 
3I/ATLAS, also known as C/2025 N1 (ATLAS) and formerly designated as A11pl3Z, is an iinterstellar comet. It was discovered by the Asteroid Terrestrial-impact Last Alert System (ATLAS) station at Río Hurtado, Chile on 1 July 2025. Note: it was mentioned (as A11pl3Z) by DaveE in a new member's introductory thread. https://www.physicsforums.com/threads/brian-cox-lead-me-here.1081670/post-7274146 https://earthsky.org/space/new-interstellar-object-candidate-heading-toward-the-sun-a11pl3z/ One...
Is a homemade radio telescope realistic? There seems to be a confluence of multiple technologies that makes the situation better than when I was a wee lad: software-defined radio (SDR), the easy availability of satellite dishes, surveillance drives, and fast CPUs. Let's take a step back - it is trivial to see the sun in radio. An old analog TV, a set of "rabbit ears" antenna, and you're good to go. Point the antenna at the sun (i.e. the ears are perpendicular to it) and there is...
