Hubble mystery light puzzles astronomers

AI Thread Summary
Astronomers using the Hubble Space Telescope discovered an unprecedented flash of light from a galaxy cluster approximately eight billion light-years away. This mysterious object exhibited a unique behavior, brightening over 100 days before dimming and eventually disappearing. Despite ongoing investigations, astronomers remain uncertain about the nature of this phenomenon, as discussed at the recent American Astronomical Society meeting in Long Beach, California. The event continues to intrigue the scientific community, highlighting the complexities of cosmic observations and the unknowns in astrophysics.

Almost three years ago, astronomers using the Hubble Space Telescope were perusing a cluster of galaxies about eight billion light-years from Earth when they came upon a flash of light unlike anything they had seen before.

Over the next 100 days, the object gradually brightened. Then it spent another 100 days growing dimmer, until it finally vanished from view.

Astronomers speaking last week at the American Astronomical Society meeting in Long Beach, Calif., still have no idea what it was — or is...

Thread 'Predictions for the Nobel Prize in Physics 2025'

Similar to the 2024 thread, here I start the 2025 thread. As always it is getting increasingly difficult to predict, so I will make a list based on other article predictions. You can also leave your prediction here. Here are the predictions of 2024 that did not make it: Peter Shor, David Deutsch and all the rest of the quantum computing community (various sources) Pablo Jarrillo Herrero, Allan McDonald and Rafi Bistritzer for magic angle in twisted graphene (various sources) Christoph...

Thread 'My experience as a hostage'

I believe it was the summer of 2001 that I made a trip to Peru for my work. I was a private contractor doing automation engineering and programming for various companies, including Frito Lay. Frito had purchased a snack food plant near Lima, Peru, and sent me down to oversee the upgrades to the systems and the startup. Peru was still suffering the ills of a recent civil war and I knew it was dicey, but the money was too good to pass up. It was a long trip to Lima; about 14 hours of airtime...
