We May Be on the Brink of Finding the Real Planet Nine (scientificamerican.com)
Most astronomers would love to find a planet, but Mike Brown may be the only one proud of having killed one. Thanks to his research, Pluto, the solar system’s ninth planet, was removed from the pantheon—and the public cried foul. How can you revise our childhoods? How can you mess around with our planetariums?

Size and albedo of the largest detected Oort-cloud object (arxiv.org)
The recently announced Oort-cloud comet C/2014 UN271 (Bernardinelli-Bernstein) is remarkable in at least three respects: (i) it was discovered inbound as far as ~29 au from the Sun (with prediscovery images up to ~34 au); (ii) it showed cometary activity already at almost 24 au; and (iii) its nuclear magnitude (Hr ~ 8.0) indicates an exceptionally large object.

Uranus' moon Miranda may have an ocean beneath its surface (phys.org)
A new study suggests Uranus' moon Miranda may harbor a water ocean beneath its surface, a finding that would challenge many assumptions about the moon's history and composition and could put it in the company of the few select worlds in our solar system with potentially life-sustaining environments.

Ion engines could take us to the solar gravitational lens in less than 13 years (phys.org)
Sending an object to another star is still the stuff of science fiction. But some concrete missions could get us at least part way there. These "interstellar precursor missions" include a trip to the solar gravitational lens point at 550 AU from the sun—farther than any artificial object has ever been, including Voyager.

Ceres: An ocean world in the asteroid belt (astronomy.com)
Remnants of an ancient water ocean are buried beneath the icy crust of dwarf planet Ceres — or, at least, lingering pockets of one. That’s the tantalizing find presented August 10 by scientists working on NASA’s Dawn mission. Their research was laid out in a series of papers published in Nature.

Saturn's moon Mimas may hide a surprisingly young ocean (knowablemagazine.org)
Saturn’s moon Mimas, known for its uncanny resemblance to the Star Wars Death Star, might harbor liquid water beneath its icy shell. If true, similar seas could be hiding in plain sight, and the outer solar system may be far more habitable than previously thought.
