Timelapse of the Green Comet that Passed Through our Solar System | PetaPixel

An astrophotographer has put together an awesome timelapse video of the green comet that passed through the solar system this past month.

Consisting of 521 images that were captured over the course of 10 hours and with the total file size coming to one terabyte of data, the video charts the long-traveling comet’s journey as it passed by Earth.

Hubble spies strange spokes on Saturn's rings after 14-year hiatus | Space

The Hubble Space Telescope captured mysterious features on Saturn's rings, signaling the start of the planet's "spoke season." 

Like Earth, Saturn is tilted on its axis and has four seasons. However, since Saturn is farther out in the solar system and has a much larger orbit around the sun, each season lasts approximately seven Earth years, according to a statement (opens in new tab) from NASA.

Saturn's rings have mysterious smudges in new Hubble Space Telescope photos | Daily Mail Online

But every 15 years or so something odd happens to them — a phenomenon that has baffled scientists ever since its discovery four decades ago.

New Hubble Space Telescope images have now revealed mysterious smudges once again in Saturn's rings, signalling that the planet's 'spoke season' is in full swing.

Organic molecules found around stars similar to our early Solar System | BBC Sky at Night Magazine

Our Solar System formed from a dusty ring of cosmic material circling the Sun , when our host star was still just a stellar newborn.

This ring - known as a protoplanetary disk - contained solid materials that coalesced through gravity over time, eventually growing into the the planets orbiting the Sun that we see today.

How did Saturn get its rings?

Without its rings, Saturn looks really boring. Super blah. Erase those bangles—as blogger Jason Kottke did (above) from a NASA photo—and the planet is the blandest sphere in our solar system.

Thankfully, at some point in the past 4.5 billion years, the cosmos gave Earth's neighborhood an upgrade: It put a big, bright, icy ring system around Saturn. But scientists don't agree on when Saturn's rings formed—or how the bangles even came to be. And that's been true for decades.
