What If the Dinosaur Killing Asteroid Hit Earth Today?

The Largest Extinction Event On Earth!

Did scientists discover a parallel universe in which time flows backwards? nope.:(

👃 What does space smell like? Weirdly enough, it’s not nothing—and astronauts have noticed some surprising scents! 🌌 After spacewalks, astronauts have reported smells like burnt steak, welding fumes, or gunpowder clinging to their spacesuits. But how can a vacuum with no air have a scent? 👉 Here’s one explanation: Ultraviolet rays from the Sun break up oxygen molecules (O2) near the ISS, creating individual oxygen atoms. These atoms stick to spacesuits and trigger chemical reactions, including ozone—a gas with a sharp, burnt smell. 👉 Another explanation? Space itself! Dying stars release molecules called polycyclic aromatic hydrocarbons (PAHs), which smell like charred foods—think burnt toast or grilled meat. These PAHs cling to spacesuits, giving astronauts a literal whiff of the universe!

Google just announced a crazy new quantum computing chip. It can solve a problem in 5 minutes that would take one of the fastest supercomputers 10 septillion years! BUT that problem was a “benchmark” problem called RCS, chosen specifically because it’s extremely hard for a supercomputer - which are still better at basically everything practical. The real reason you should care about quantum computers and this new chip is less about beating supercomputers at things they’re already great at and more about doing new things - like really accurate simulations of nature at a quantum level that could be used for drug discovery or battery development or more.

NASA's probe will experience temperatures that melt diamond.

That Time It Rained For 2 Million Years!

One of the most terrifying places in the universe.

If humans have only ever been 12 kilometers down... how do we know what’s inside? Well, scientists used to have some interesting ideas about this! But now, one big answer is: Earthquakes. Here’s how it works.

✨ Meet WOH G64: the largest star we've ever imaged outside our Galaxy! 🪐 This red supergiant lives in the Large Magellanic Cloud and is up to 2,000 times the size of our Sun—big enough to stretch all the way to Saturn if it were in our Solar System! 🌌 But there’s more: WOH G64 is surrounded by a mysterious dust cloud that’s oddly shaped. Could it be gas jets? A hidden companion star? Scientists aren’t sure yet! 🤔 And because it’s in a low-metallicity galaxy, this star gives us fresh insights into stellar evolution in different environments. One day, it’ll go supernova, enriching its galaxy with heavy elements. For now, though, we get to witness its dramatic finale! 💥

Earth lore is insane… trying to fit the history of earth in 90 seconds is more insane

An international team of astronomers recently uncovered a unique system named J1721+8842. This isn’t just any gravitational lens—it’s the first-ever compound lens made by the alignment of two galaxies! Why does this matter? Well, this discovery could help scientists more accurately measure the Hubble constant, potentially resolving a major debate in cosmology. Who knew that two galaxies aligning perfectly could unlock new secrets of the universe?

Spacetime ripples explained simply.

We don’t exactly know it got there, but it’s most likely from rivers and hydrothermal vents

his is basically mind reading: Scientists re-created what people see by reading their brain scans. But here’s how it actually works... Scientists trained a machine learning system on brain scans from four participants as they viewed thousands of photos. These brain scans gathered information from two regions of the brain: one that registers the contents of an image and another that registers the layout and perspective...

This isn’t exclusive to the United States by the way, the U.S. just has more data on it because we are literally everywhere
