A giant gas exoplanet in an unusually large orbit has been directly imaged by astronomers via the Young Suns Exoplanet Survey (YSES). It is 20 times as far from its star as Jupiter is from our sun.

Astronomers have discovered many giant planets, similar to Jupiter or Saturn, orbiting other stars. Some of these – called hot Jupiters – are unlike any planets in our solar system, however, circling
“It’s increasingly seeming that the solar system is something of an oddball,” said Gregory Laughlin, a planetary scientist at the University of California, Santa Cruz. “While it’s still too soon to know for sure how odd the solar system is, if it turns out to be a cosmological anomaly, then so might be Earth – and life.”

“This discovery is a snapshot of an environment that is very similar to our Solar System, but at a much earlier stage of its evolution,” says Alexander Bohn, at Leiden University in the Netherlands, about the image of a young, Sun-like star with multiple planets directly imaged located about 300 light-years away in the Southern constellation of Musca (The Fly) in July of 2020 by the European Southern Observatory’s Very Large Telescope (ESO’s VLT). Bohn’s team imaged this system during their search for young, giant planets around stars like our Sun but far younger. The sta

When talking about planetary ring systems, Saturn and Jupiter likely spring to mind they are our closest ringed neighbors, after all. But although impressive, their rings aren’t that large, in the grand scheme of things. Jupiter’s aren’t that large even when judging only by our Solar System. Neptune and Uranus also have rings, but they’re tinier.

Luckily, the Universe is a huge place, and there’s no shortage of beautiful ring systems to enjoy. There are also plenty of grand, sprawling ones to take your breath away. So, today, let’s take a look at what these ring systems actually are, how they form, and the biggest ones we’re spotted so far.
