AI Thread Summary
Beta Pictoris b has been confirmed to have an exceptionally fast rotation, completing a day in just 8 hours, making it the fastest-spinning exoplanet known. This measurement marks a significant achievement as it is the first time astronomers have successfully measured the rotation of an extrasolar planet. In comparison, Jupiter, the fastest planet in our solar system, takes nearly 10 hours to complete a rotation. The findings highlight the unique characteristics of Beta Pictoris b and its extreme rotation speed. Such discoveries enhance our understanding of planetary dynamics beyond our solar system.

Do you feel there is never enough time in a day? Then don't move to Beta Pictoris b. A day on this fast-paced exoplanet lasts just 8 hours, making it a poor choice for the temporally challenged.

What's the news here? Jupiter, in our own solar system, has a day equal to just under 10 hours.

The news is twofold:

First, this is the first time astronomers have measured an extrasolar planet's rotation.

Second, the planet spins faster than any in our solar system. Jupiter, the Sun's fastest-spinning planet, rotates once every 9 hours, 55 minutes.
 

Thread 'How feasible is home radio astronomy?'

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...

Thread '3I/ATLAS, Interstellar Comet'

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...
