An Extreme Cousin for Pluto? Possible Dwarf Planet at Solar System Edge (ias.edu)
A small team led by Sihao Cheng, Martin A. and Helen Chooljian Member in the Institute for Advanced Study’s School of Natural Sciences, has discovered an extraordinary trans-Neptunian object (TNO), named 2017 OF201, at the edge of our solar system.

Universe expected to decay in 10⁷⁸ years, much sooner than previously thought (phys.org)
The universe is decaying much faster than thought. This is shown by calculations of three Dutch scientists on the so-called Hawking radiation. They calculate that the last stellar remnants take about 1078 years to perish. That is much shorter than the previously postulated 101100 years.
