Topic: Scientists find possible signs of life on Venus (Read 492 times)

The "first sign" was some asteroid that came from Mars with alleged fossil prints. Its only a matter of time for more evidence to come from there from the many missions ongoing and planned. Venus was actually unexpected, but then again what could we possibly know about life in the universe?

Studying Venus is difficult due to the planet's environment, but i suspect more probes will head there to investigate about those interesting readings.

Your "principle" sounds a lot like the Fermi paradox, but i wouldn't limit the scope to this mere solar system.

Also don't forget the Solar System has 8 planets, and a whole bunch of satellites and dwarfs (and the asteroid belt, possible remains of planet. After Neptune the next celestial object is called Eris, yes, you read that right, Pluto comes after Eris. The solar system is incredibly huge, but its but a grain of sand in the vast universe. Earth would by like a sub atomic particle or something.

The moon is "meh" but several countries are visiting because its "close". Even Israel tried but couldn't quite brake properly and left a bunch of debris on its surface. I guess they'll try again later. If you want the best pictures of the moon, look at the Chinese Chang'e probes. Even SpaceX is planning to send tourists to fly by it. NASA is also revisiting, for some reason.

It is very interesting but surprising as well.
I would not surprised if their is live in Venus. It would be very selfish for us (people) to believe that we are alone in this universe.
Personally, I hope that scientists will find life on Venus because this would be very revolutionary for the world and many missions would start going to other planets.

this may be the first sign of other life that appears to exist beyond earth...

btw, I believe there is another life beyond the earth but our technology is still not able to reach them. I have the principle that in this vast solar system it is not possible only on earth to have life.

Blue Origin, the space company founded and funded by Amazon head Jeff Bezos, is planning to make its 13th trip to space on Thursday, using a New Shepard rocket that will be flying for the seventh time, which will set a record for rocket recycling.

Mission NS-13 will be carrying a dozen payload to the edge of space and back, including a lunar landing sensor demonstration that will test technologies for future moon missions as part of NASA's Artemis program.

The sensor will be the first payload to ride mounted to the exterior of New Shepard rather than inside its capsule.

SpaceX, another commercial space outfit headed by a famous billionaire in the form of Elon Musk, has so far used a single Falcon 9 booster up to six times. It's worth noting, though, that the Falcon 9 is a different class of rocket that is used for more technically complicated orbital missions.

A few of the other payloads on board this flight of New Shepard include a test of a new system to autonomously grow aquatic plants that could supplement a crew's diet and a new cooling system developed by NASA for spacecraft electronics.

This is just so exhilarating to think that there is microbial life completely different from what we are used to know. Just sit and think what it will evolve in! Will the evolved creation be like human?

so you prefer that one day you wake up and run into this guy:



we need to know what's on other planets, maybe there are more beneficial things on other planets. The best way to be protected Is if we know what is on other planets. we have already seen how our weapons are capable of creating catastrophic destruction, now imagine if there are aliens with technology superior to ours? would you wake up and become a slave to this big-headed guy in this photo

Anybody can be a bit deranged. Even scientists. How ridiculous, searching for life on other planets! We really need to be looking for intelligence on Earth, right?

Many of the essential activities of life as we know it, such as the formation of DNA and passage of things through cell walls, are based on a liquid water medium. Really they are based on a narrow range of temperatures.

To find life at say 700F even microbes, would be truly fascinating as it would be a study of something completely, utterly alien.

...
But first of all we need a common understanding of extraterrestrial life, is it just some microbial life? Or something more advanced like us humans? Venus is such a hot planet which would make it very hard for anything to exist. It don't think we will find life on any planet around planet. Maybe in the past but not now anymore.

According to The Guardian, scientists believe the discovery of a rare gas in the clouds of Venus could indicate signs of microbial life on the planet.

What do you think? Could this be the first evidence of extraterrestrial life?

....
You are dead wrong.  Which climate denial blog did your numbers come from? Venus reflects 70% of the radiation that hits it as evident by its brightness in the sky.   ....

....The greenhouse effect is definitely why Venus is so hot.  

To get to that conclusion, they have to set pre existing conditions that would allow liquid water on the surface. In other words, they have to set pre conditions that would create the desired outcome. But even then, it's a very weak assertion.

Sun output = 30% less --> Solar irradiance on Venus = 40% higher than current Earth. Do you really believe you'd have oceans here with 40% higher solar?

Actually, if they had oxygen in either Venus or Mars atmosphere, that would be a signal of life. But both have high co2, which indicates the opposite. All that's left to search for under category "life" is microbes that are anaerobic and/or live in high sulfur conditions.

Now let's go back to the headline. "Venus may once have been habitable."

Really? That "early 2 billion years" is a continual rain of asteroids, hellish conditions of continual volcanos... it's the planet becoming a planet, aggregating. So if it has a lot of water, that water becomes water vapor. Huge amounts of it, just like now Venus has huge amounts of co2.

In the absence of a magnetosphere, the solar winds would strip the H20 and other volatiles apart, and ultimately you'd be left with the tail end of the energy equation, CO2. And that's what you have on Venus.

With enough mass in the atmosphere (initially h20 if you like), the surface pressure would easily force water vapor into liquid form. That's a steam boiler, not an ocean. Evil Kneivel's rocket was just that, superheated steam.

Earth is by definition in the 'habitable zone'. Venus and Mars are not. Note that the known fact that Mars had ancient oceans is contrary to the hypothesis of an ancient dimmer sun. If anything, it would indicate an ancient stronger sun.

The total solar flux at the Venus orbit is 2622 ± 6 W/m2 (Moroz et al., 1985). Due to its high albedo the planet absorbs only 157 ± 6 W/m2 on average, less than that deposited on Earth (~240 W/m2), despite the fact that Venus is 30% closer to the Sun.
