Beyond the orbit of Neptune, a dwarf planet is found to have a ring

LA Times  

There may be more ringed objects in the outer solar system than anyone knew. In addition, it also turns out that there are a few reasons why ring systems would be more common in the outer solar system than the inner solar system. If rings are formed when two objects collide, they could be more likely to do so in the outer solar system, where the ejected material might not be moving fast enough to escape the gravity of a central body, Ortiz explained. It’s also possible that there are more rings in the outer solar system because there are simply more satellites there than in the inner solar system. What’s next Ortiz and his collaborators are continuing to use occultation to study bodies in the outer solar system and see whether any of them have rings.

Hubble finds gargantuan structure with nine mysterious rings in space

India Today  

Hubble telescope has captured a gargantuan structure in deep space rippling with nine star-filled rings around it. The galaxy, LEDA 1313424, is surrounded by nine star-filled rings after an “arrow” — a far smaller blue dwarf galaxy — shot through its heart. While eight rings around the galaxy were discovered by the Hubble Telescope, astronomers confirmed a ninth ring using …

But this newly discovered ring is unlike the telltale halos of ice and dust that orbit planets such as Saturn and Jupiter in a key aspect—it is unusually far from its host body, according to a study published Wednesday in the journal Nature. The new ring system encircles a small, celestial body named Quaoar, located in what astronomers call the …

The rings around Neptune

The Hindu  

If we are asked to name a planet in the solar system that has rings around it, our answer would be Saturn, perhaps nine out of 10 times. While scientists suspected for some years that Neptune must have rings around it, it was only when Voyager 2 made its flyby that it was proven beyond any doubt. And then, in …

Pluto's neighbour, the exotic Haumea has a ring around it

India Today  

Astronomers discovered the first-known 'egg' that later became an official dwarf planet, called 'Haumea' to have unexpected thin ring-like bands made up of particles and debris, circling around it. This ring system suggests that the small bodies around the bizarre planet could also host rings-and this poses a great challenge for visiting spacecrafts. The ring revelation This discovery marks the …

Ring discovered around 'potato-shaped' dwarf planet Haumea

ABC  

A ring system has been found around a dwarf planet for the first time — the distant, potato-shaped Haumea, which lies beyond Neptune. Key points: Haumea is a dwarf planet that orbits in the outer solar system, roughly 6.4 billion kilometres from the Sun Scientists have detected a dense, dark ring of debris around it The discovery suggests rings around …

When we think of a ringed planet, most of us envision something akin to the intricate grooves of Saturn’s ring system, which have fascinated humans for centuries. Yet a recent astronomical observation seems to suggest that the distant dwarf planet Haumea, which possesses only about one-third the mass of Pluto, may have a ring as well. As a dwarf planet, …
