A balanced ratio of ocean to land is believed to be essential for an Earth-like biosphere and one may conjecture that plate-tectonics planets should be similar in geological properties.
After all, the volume of continental crust evolves towards an equilibrium between production and erosion.
EarthSky | Keck Planet Finder begins search for other Earths
Astronomers have discovered several thousand exoplanets so far. They are worlds orbiting distant suns, and they range in size from some larger than Jupiter to small rocky planets like Earth. The rocky planets are most likely to be habitable. But small rocky planets are difficult to detect.
These scientists said the Keck Planet Finder is the world's most advanced high-resolution spectrometer for visible wavelengths. Its purpose is to search for smaller planets like Earth orbiting other stars, in particular ones in the habitable zone .
Helium-enhanced planets along the upper edge of the radius valley | Nature Astronomy
The Kepler survey revealed that the radius distribution of sub-Neptunes is bimodal: there is a scarcity of planets between 1.5 and 2.0 R ⊕ . However, the mechanism that creates the valley is unknown.

Moon and planets viewing event with the physics department – The Stute
With Stevens being so close to New York City, skywatching is not often a popular (or possible) outdoor activity. Nighttime light pollution, lack of open space, and a general lack of opportunity to take some time and look up at the stars make sure of that.
Stevens students did exactly that on November 9 at Pier C Park. With daylight savings, the sky in the evenings is now dark enough to see Jupiter and Saturn at the same time. This month also had a full moon very early, enabling skywatchers to view that as well.

Another first for super-powerful James Webb Space Telescope | Inquirer and Mirror
(Nov. 17, 2022) NASA’s new James Webb Space Telescope recently confirmed the first ever detection of carbon dioxide in the atmosphere of an exoplanet.
This detection marks a first major step in the telescope’s mission of detecting and characterizing the atmospheres of planets around other stars.
EarthSky | Fiery hourglass star seen by Webb
EarthSky editors posted this story, making some minor edits, using a statement from the European Space Agency.
Astronomers said this week (November 16, 2022) that they’ve used the Webb space telescope to catch a newly forming star, designated L1527, whose star-forming cloud makes the shape of an hourglass.
New spacecraft and missions to watch in 2023 | The Economist
During the summer of 2023 America's space agency, NASA , plans to launch its Psyche spacecraft to explore an iron-rich asteroid of the same name, 16 Psyche, which is thought to be a remnant of a protoplanet from the earliest days of the solar system.
Continuing the asteroid theme, NASA 's OSIRIS-REX probe is already on its way back to Earth after its rendezvous to take samples of the asteroid Bennu in 2020.
