Instead, there's a natural speed limit imposed by safe levels of radiation due to hydrogen, which means humans couldn't travel faster than half the speed of light unless they were willing to die almost immediately. Dammit. [Natural Science]

Radio (microwaves) is not the only form of electromagnetic radiation.
I can't locate the original paper but here is a review of one written by a man I know. A physicist with an amazing, if somewhat impractical, imagination. The antithesis of how many view today's scientists.
adsabs.harvard.edu...
This paper demonstrates reasons why research supporting SETI and Communication with Extraterrestrial Intelligence should be broadened to optical wavelengths rather than focusing almost entirely upon microwave wavelengths and technologies. New perceptions regarding the feasibility of laser technologies, along with reassessments of signal-to-noise considerations, show both the desirability and feasibility of optical interstellar transmissions, especially at IR and visible wavelengths. It is shown that utilization of the large bandwidths available at optical wavelengths greatly improves the possible use of such endeavors.

Exactly. If you want to look for life, biomarker gases are what you want to look for.
Radio signals are super basic. Advanced technology will not use them. If we were serious, we would search for quantum based communication in some way.
Biomarker gases are something we can try to detect today.

Hostile to life as we know it.
Something tells me we are going to find some pretty cool things out there 1 day.

If there could be life on a "Super Venus", then there could also be life on Venus. And I don't know of anyone that postulates that.

It would have two times or more gravity.
you could not move!
you all fall for this?
they dont know. they just make it up.
good way to get money for NASA.

Carl Sagan did at one time.
It was thought that there could be life in Venus's upper atmosphere where it is cooler. However we've studied the planet in detail since then and found no such life.
This is a different planet unlike Venus or anything else in our solar system. We do not know its composition much less atmosphere, weather etc......yet.
So the jury is still out.

Regardless. The headline says "Super-Earth" and "Habitable" . But the article says "more likely" it's a "Super-Venus" that's "hostile to life".
Classic disingenuous link-bait article. And that was the point I was making.
