CALIFORNIA ELECTION CHAOS: "UNNECESSARY DRAMA"
"It seems like every single time we begin to get momentum out here in California, shenanigans began to get thrown at us." @JeffDornik also bring up how CA is unsure if their votes "really count".

🌟 Astronomers have witnessed a supernova that exposes the raw, hidden core of a dying star—something never seen before.
In a remarkable discovery, scientists studying SN 2021yfj have identified a new class of supernova, dubbed Type Ien, that lays bare the innermost regions of a massive star. Unlike typical supernovae, where outer shells of hydrogen and helium dominate, this explosion was rich in silicon, sulfur, and argon—material usually locked away deep inside stellar giants.
The progenitor star, located in a star-forming region 2.2 billion light-years from Earth, somehow shed all of its outer layers before exploding. This unprecedented stripping exposed its silicon- and sulfur-rich core, offering the first direct observational evidence of the “onion-like” internal structure that astrophysicists had long theorized but never glimpsed so deeply before.
Discovery came through the Zwicky Transient Facility (ZTF), which scans wide regions of the sky for brief, energetic phenomena. As scientists rushed to secure a spectrum, challenging weather nearly foiled their efforts—until observatories at W.M. Keck in Hawai‘i captured the critical data, revealing the star’s unusual fingerprint.
SN 2021yfj’s unique chemical makeup and violence suggest it might have lost mass via extraordinarily powerful episodes—possibly from interactions with a companion star or rare internal eruptions. The scale and nature of these processes challenge classical models of how massive stars live and die.
This cosmic oddity opens new questions about stellar evolution and explosion mechanisms. As only one such supernova has been observed so far, astronomers are eager to find more and unravel the secrets inside dying stars.

Earth’s precise planetary tilt may be the reason it can host life.
Planets don’t just spin — they lean. This tilt, or “axial tilt,” dramatically shapes a planet’s climate, weather patterns, and seasonal behavior.
Earth’s 23.26° tilt is the reason we experience seasons. But other planets take it to extremes: Uranus is tilted nearly 98°, rotating almost entirely on its side, leading to seasons that last decades. Venus spins in the opposite direction with a tilt of 177.3°, resulting in a day that’s longer than its year. Meanwhile, Mercury’s nearly upright posture means it barely experiences any seasonal variation.
These cosmic inclinations aren’t just quirks — they’re climate-defining forces. A planet’s tilt determines how sunlight hits its surface, driving winds, storms, and the potential for habitability. Scientists also use tilt as a clue when studying exoplanets, helping them assess if distant worlds could support life. The more we understand axial tilt, the better we grasp the delicate balance that makes Earth — and perhaps other planets — livable.
