Is it theoretically possible for there to be such a thing as a "gas moon" as opposed to a rocky one?
Do any laws or models specifically prohibit the formation of gaseous moons?

Is it possible, by monitoring the brightness of stars, to find a “copy of the Earth + Moon” near them?
More than a dozen Earth-like planets have been discovered around nearby stars based on observations of changes in the brightness of their sun as they pass across its disk (transit events). If an Earth-...

Would ocean tides on the moon of a gas giant really be kilometers high?
I was reading an article on exomoon habitability constrained by illumination and tidal heating. The article imagines an Earth-like exomoon around Jupiter-like host planet. That got me thinking about ...

SETI: Are there holes in the EM spectrum that are quiet enough to communicate at decently large distances?
So this is a variant of this other question.
I know stars are big, they radiate a lotta energy, they have spectral lines. But how dense are these spectral lines and is there a noise floor at ...

Is there a way to calculate/estimate the orbital period of an exoplanet from only one transit detection?
I understand that multiple transit detections of an exoplanet are almost always used to derive its period, but is there a way to do it with only one transit detection? As in, with only one available ...

Is this scientifically useful exoplanet transit data? [closed]
For a physics project, I am trying to derive properties of exoplanets through their transit light curve. I tried to get the data myself, on the known exoplanet Qatar-6b.
My Equipment:
8" Newt. ...

Where can I find datasets for all confirmed exoplanets, terrestrial exoplanets, and Super-Earth exoplanets?
"The NASA Exoplanet Archive" (https://exoplanetarchive.ipac.caltech.edu/) implies that there are 5,197 confirmed exoplanets. The "5,197 Confirmed Planets 11/02/2022" link leads to ...

Winds or waves in specific conditions?
Winds are mainly produced by differences in temperature of the atmosphere and waves are mainly produced by winds.
However, could a rogue planet (without orbiting any star and with a cold core so no ...

If you decreased the mass of a planet, but kept the mass of the atmosphere the same, would the air density decrease?
So, I know that atmospheric pressure is a result of both the atmospheric mass and the force of gravity acting on it. If you were to decrease a planet's gravity, but keep the atmospheric mass the same, ...

How to obtain exoplanets transmission spectra from JWST's NIRISS data of WASP96?
I was having a look at JWST's NIRISS data of WASP96 (specifically at the x1dints fits file which should be already calibrated). From this, I would like to obtain a result in a fashion similar to the ...

Does every Goldilocks planet in various solar systems inevitably have massive amounts of concentrated $\rm H_2O$ meteors?
I’ve always been fascinated with the Anthropic Principle. Our universe seems to have our Chemical, biological, and physical properties/laws designed to favor the existence of life. Although the human ...

Is the transit technique for exoplanet detections part of the "Wide-Field Precision Photometry Revolution"?
In a exoplanet focused lecture I was informed that the two main techniques for the detection of exoplanets were: radial velocity (VR) and transit. These were very briefly explained to us.
When ...
