Screenshot of social media post. Reads, "Everyone was saying that the May geomag activity had no impact on the satellites. Of course we knew this was wrong. Over one hundred sats re-entered during this period and now a paper is showing that thousands of Starlinks had to move. Holy fuck. Imagine if those thousands had to re-enter. This. Is. Insane. We. Must. Stop. Launching. Shit. NOW. https://spaceweather.com"
I have no photos or videos, but I was on Topsail Island on vacation on June 4th around 11pm, where I saw a decently bright moving object erupt with a huge v-shaped tail for atleast 30 seconds. The tail was a faint green color. It fell from the eastern sky into the northeastern sky.
Google has been particularly unhelpful. Was wondering if you fine folks had any idea. I'm assuming space debris. But I cant find any other reports of anyone seeing it.
As it studies cosmic microwaves, the Simons Observatory in Chile aims to help prove or disprove cosmic inflation, a notion that the universe expanded rapidly in the moment after the Big Bang.
The Simons Observatory, a group of microwave telescopes in the high desert of Chile, is starting to gather data to attempt to prove or disprove the theory of inflation.
In a hypothetical scenario, small, primordial black holes could be captured by newly forming stars. An international team, led by researchers at the Max Planck Institute for Astrophysics, has now modeled the evolution of these so-called "Hawking stars" and found that they can have surprisingly long ...
Peering deep into 'The Brick,' a dark, chaotic gas cloud at the heart of the Milky Way, the James Webb Space Telescope uncovered secrets that could shake up theories of star formation.
On July 19, 1952, Palomar Observatory was undertaking a photographic survey of the night sky. Part of the project was to take multiple images of the same region of sky, to help identify things such as asteroids. At around 8:52 that evening a photographic plate captured the light of three stars clust...
A strange pair of galaxies several billion light-years away could be evidence of a hypothetical 'crease' in the Universe's fabric known as a cosmic string.

> Scientists use the LOFAR telescope to observe low-frequency radio waves from satellites in large constellations for the first time. “Unintended electromagnetic radiation” emanating from onboard electronics in Starlink satellites was detected which could impact astronomical research. Further study is now ongoing.
Just because time is relative does not mean time is subjective. Time is a fundamental objective part of reality, and time and distance relativity is probably less weird than you think it is. There …
This is a chart of metric values to help in understanding the large distances of outer space. Metric is perfect for providing an easy understanding of both absolute and relative distances in astron…
The age of the universe is about 13.75 billion years. The diameter of the observable universe is estimated at about 28 billion parsecs (93 billion light-years). As a reminder, a light-year i…
