Some good quality weirdness, results consistent with numerous planets of the same size but not happening with any periodicity:

Meet the Ploonets! Runaway Moons with Delusions of Planethood Get Astronomy's Cutest Name Ever
What do you call a runaway exomoon with delusions of planethood? You call it a "ploonet," of course.
Scientists had previously proposed the endearing term "moonmoons" to describe moons that may orbit other moons in distant solar systems. Now, another team of researchers has coined the melodious nickname "ploonet" for moons of giant planets orbiting hot stars; under certain circumstances, these moons abandon those orbits, becoming satellites of the host star.
The former moon is then "unbound" and has an orbit like a planet's — ergo, a ploonet. [Top 10 Amazing Moon Facts]
Ploonets — and all exomoons, for that matter — have yet to be detected. But ploonets may produce light signatures that planet-hunting telescopes could identify, researchers reported in a new study. Their findings were published June 27 in the preprint journal arXiv and have not been peer-reviewed. ...
Sixteen Images for Spitzer's Sweet 16
NASA launched its Spitzer Space Telescope into orbit around the Sun on Aug. 25, 2003. Since then, the observatory has been lifting the veil on the wonders of the cosmos, from our own solar system to faraway galaxies, using infrared light.
Managed by NASA's Jet Propulsion Laboratory in Pasadena, California, Spitzer enabled scientists to confirm the presence of seven rocky, Earth-size planets in the TRAPPIST-1 system. The telescope has also provided weather maps of hot, gaseous exoplanets and revealed a hidden ring around Saturn. It has illuminated hidden collections of dust in a wide variety of locations, including cosmic nebulas (clouds of gas and dust in space), where young stars form, and swirling galaxies. Spitzer has additionally investigated some of the universe's oldest galaxies and stared at the black hole at the center of the Milky Way.

Design for the first "Space Hotel" revealed.
A 190 metre diameter wheel, containing 24 accommodation pods around its perimeter, will revolve to provide a semblance of gravity. Facilities are planned to be comparable to a cruise liner.
Quoted timescale target of 2025 seems highly optimistic though!

I'll tempt fate if I want to...Just don't tempt fate by asking the on-board computer to open the pod doors...
The design has been around for a long time. However, the cost and logistics may make it 2050 rather than 2025.Design for the first "Space Hotel" revealed.

https://www.bbc.co.uk/news/science-environment-49648746Water found for first time on potentially habitable planet
By Pallab GhoshScience correspondent, BBC News
Astronomers have for the first time discovered water in the atmosphere of a planet orbiting within the habitable zone of a distant star.
- 1 hour ago
The finding makes the world - which is called K2-18b - a plausible candidate in the search for alien life.
Within 10 years, new space telescopes might be able to determine whether K2-18b's atmosphere contains gases that could be produced by living organisms.

Something Is Killing the Universe's Most Extreme Galaxies
In the most extreme regions of the universe, galaxies are being killed. Their star formation is being shut down and astronomers want to know why.
The first ever Canadian-led large project on one of the world's leading telescopes is hoping to do just that. The new program, called the Virgo Environment Traced in Carbon Monoxide survey (VERTICO), is investigating, in brilliant detail, how galaxies are killed by their environment. ...
Galaxy clusters
Where galaxies live in the universe and how they interact with their surroundings (the intergalactic medium that surrounds them) and each other are major influences on their ability to form stars. But precisely how this so-called environment dictates the life and death of galaxies remains a mystery.
Galaxy clusters are the most massive and most extreme environments in the universe, containing many hundreds or even thousands of galaxies. Where you have mass, you also have gravity and the huge gravitational forces present in clusters accelerates galaxies to great speeds, often thousands of kilometres-per-second, and superheats the plasma in between galaxies to temperatures so high that it glows with X-ray light.
In the dense, inhospitable interiors of these clusters, galaxies interact strongly with their surroundings and with each other. It is these interactions that can kill off — or quench — their star formation.
Understanding which quenching mechanisms shut off star formation and how they do it is the main focus of the VERTICO collaboration's research. ...

There are rules, but these will be official names.
(c) BBC. '19Astronomers have discovered a giant planet that, they say, should not exist, according to current theories.
The Jupiter-like world is unusually large compared with its host star, contradicting a widely held idea about the way planets form.
The star, which lies 284 trillion km away, is an M-type red dwarf - the most common type in our galaxy.
An international team of astronomers has reported its findings in the journal Science.

That title is 'exciting' hype.GALAXY NEXT TO US IS ‘VIOLENT’ AND COMING TO EAT THE MILKY WAY, SCIENTISTS SAY
Source: The Independent
Date: 2 October, 2019
The vast Andromeda galaxy, next to ours, has a violent past that will culminate in it eating our Milky Way, astronomers say.
The galaxy's powerful past has seen it eat several smaller galaxies just as it will go on to swallow ours, researchers say.
