If things have felt a little too quiet in the cosmos, things are about to get very interesting.
During the month of December, only one planet will *actually* be stationing retrograde — it just so happens to be the most ominous, Mercury. Typically, Mercury retrogrades only three times per year, but 2022 obviously had to be extra and go out with a bang.
Weird young super-Jupiter challenges theories of planet formation | Space
A newly discovered planet has the diameter of Jupiter but eight times its mass, giving it twice the density of Earth despite being composed mostly of gas.
The exoplanet , which lies around 310 light-years outside the solar system in the constellation Centaurus, orbits a sun-like star and is just 15 million years old, making it a relative infant in cosmic terms and when compared to our 4.6 billion-year-old planet.
Nascent gas giant planets may be lurking in dusty disk
Using data from the Atacama Large Millimeter/submillimeter Array (ALMA) in Chile and the Jansky Very Large Array (VLA) in New Mexico, they found that the disk is 80–100 times wider than the distance from the sun to the Earth, a span known as an astronomical unit .
The disk is unstable and collapsing in a region roughly 20 astronomical units from its young star. The VLA had previously identified several clumps of matter in the same area, and their formation may be driven by this gravitational instability.
Measuring The Obliquities Of The TRAPPIST-1 Planets With MAROON-X - Astrobiology
A star’s obliquity with respect to its planetary system can provide us with insight into the system’s formation and evolution, as well as hinting at the presence of additional objects in the system.
However, M dwarfs, which are the most promising targets for atmospheric follow-up, are underrepresented in terms of obliquity characterization surveys due to the challenges associated with making precise measurements.
Mars Once had Enough Water for a Planet-Wide Ocean 300 Meters Deep - Universe Today
Today, Mars is colloquially known as the “Red Planet” on a count of how its dry, dusty landscape is rich in iron oxide (aka. “rust”). In addition, the atmosphere is extremely thin and cold, and no water can exist on the surface in any form other than ice.
In other words, the composition of these meteorites represents Mars’ original crust before asteroids deposited water and various elements on the surface. Since Mars does not have active plate tectonics like Earth, the surface is not subject to constant convection and recycling.
Congressional Testimony By Natalie Batalha: Early Science Results for Transiting Exoplanets ...
JWST is ushering in a new epoch of exoplanet science that will rewrite textbooks. Progress will stem largely from the characterization of exoplanet atmospheres enabled by JWST technology. Herein, I will focus on the method of transmission spectroscopy.
To date, thousands of planets orbiting other stars in the Galaxy have been identified.
EarthSky | The moon and Jupiter pair up on December 1
Look for the waxing gibbous moon after sunset on December 1, 2022. The bright “star” near it is the planet Jupiter, the largest planet in our solar system. Other than the moon, Jupiter is the brightest object in the southern sky this month.

25 Space Photos That Make You Feel Small and Full of Wonder

Why do stars twinkle?
Why do stars twinkle while planets do not? Like many things astronomical, the answer lies in our atmosphere
Look in the southern sky after dark for Jupiter to form a right triangle with bright stars Fomalhaut and Altair. About halfway between those stars, you'll also find Saturn.
