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-...

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 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 ...

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 ...

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 ...

How would I see if there is a transit in this light curve?
I am trying to detect if some binary star systems have exoplanets orbiting them. I've been completing this project for many weeks now, and have managed to write some code that will plot light curves ...

Are there planets orbiting something else than a star?
Exoplanet is a planet that orbits a star different from our Sun.
Are there any planets (that we know of) which orbit something else? (Like different giant planet or black hole or maybe neutron star.)

How can spectroscopy be used to find the composition of exoplanet atmospheres?
How can astronomers use light spectroscopy to measure the composition of different planets when they can't directly image the planet because the star that they are orbiting is so much bigger and ...

Is our solar system really that odd?
I have been learning about the solar system from popular science shows. In these shows they suggest that, after having seeing around 2500 other solar systems, astronomers have concluded that our ...

Did we adapt to Earth or Earth to us? [closed]
I often hear that Earth is a unique planet because it has life and it has its own inhabitance. We also see a proper balance between plants and humans and other animals. Why life is not possible on ...

Infrared Telescopes and Surface Area
I have been reading a paper on about exoplanets, specifically measuring the temperature of exoplanets using infrared telescopes.
The paper compares exoplanets with neutron stars (NS) remarking that ...

How to track orbit of an exoplanet?
I was wondering if there is an established method to keep track of the orbit of an exoplanet assuming we know $a$ - the semi-major axis of the orbit, $e$ - the eccentricity of the orbit, and $i$ - the ...

Proxima Centauri radio signal
I have recently seen an article about an unusual radio signal coming from Proxima Centauri region.
I understand there is a debate around the nature of this signal.
My question is related to this ...
