Yep—sharks have been around for 400+ million years, while trees only showed up about 350 million years ago.
Mind. Blown.

Now here’s the twist: Saturn’s iconic rings? Total babies.
They’re just 100 million years old—barely a blink in cosmic time.

So the next time someone says sharks are scary, remind them—they’re not just predators, they’re prehistoric legends.
They’ve survived five mass extinctions, outlived the dinosaurs, and watched Earth evolve for eons.

Meanwhile, Saturn’s still flaunting its brand-new bling.
The universe has a wild sense of timing.

Types of "Holes" in the Cosmos

Not all cosmic "holes" are the same — and they’re not just empty space.

Astronomers may have just found one of the youngest neutron stars ever—possibly only 14 years old.

Discovered in a dwarf galaxy 400 million light-years away, the object—VT 1137–0337—was spotted during the Very Large Array Sky Survey. It wasn’t visible in 1998 data but lit up with strong radio signals by 2018, suggesting it formed sometime in between.

What makes this find special? Its radio signal is 10,000 times brighter than the famous Crab Nebula. Scientists think it’s a newborn pulsar wind nebula—powered by a rapidly spinning neutron star—and it may even be evolving into a magnetar, one of the universe’s most magnetic and mysterious objects.

This rare discovery gives us a glimpse into how neutron stars and magnetars form—and how they might be connected to fast radio bursts.

Maybe the universe is giving me a sign

Okay, universe, we get it — you're huge. 🥹
