He does say that it would not accelerate quickly. But it would have to accelerate quickly enough to reach escape velocity. So. Assuming it would work, it may have to be a hybrid. Interesting nonetheless.Tweet

My brother says told me about this last night, says they released something early by mistake. Apparently they've detected phosphine, which some claim can only be produced biologically (sort of? It's on Jupiter already apparently, so I don't know. Maybe we don't know a way for it to appear on rocky planets). I've heard enough wild astronomy claims to remain skeptical, but who knows. If true, well...Tweet

Rumours are that they've found signs of life on Venus
Yes, they've been doing research into phosphine rigorously over the last decade before reaching the conclusion that it's impossible (to our current knowledge) for a rocky planet to produce phosphine without some form of life. Alien life on a planet as close as venus is very exciting, it more or less proves how common it will be throughout the universe.Tweet

What’s it called?Anyone watched the new Netflix documentary about Challenger? Lucas saying he’d make the same decisions he made then all over again despite knowing it blew up and killed 7 people is one of the most extraordinary things I’ve ever seen.
Challenger: The Final Flight. Definitely worth a watch.What’s it called?
Are these all supposed to be asteroids that have actually hit the earth ?
No, they're all still up there whizzing around!
Cheers. I've been to the Meteor Crater in Arizona and it was absolutely massive.I believe if they come in contact with earth they are meteorites rather than asteroids.
I don't think this is correct. Meteoroids turn into meteors/meteorites, but asteroids just stay asteroids (as long as they don't split up into a bunch of meteorites).I believe if they come in contact with earth they are meteorites rather than asteroids.
I stand corrected. So what's the difference between meteoroids and asteroids? Does the first group orbit the earth and the latter the sun?I don't think this is correct.

I think a meteoroid is mostly just a smaller piece of an asteroid, but I don't know how they are defined exactly.I stand corrected. So what's the difference between meteoroids and asteroids? Does the first group orbit the earth and the latter the sun?
A meteor is an asteroid that enters the atmosphere. If it physically survives to impact the surface it's a meteorite. So, asteroid in space, meteor as it burns through the atmosphere and a meteorite is the rock/iron that's left.I think a meteoroid is mostly just a smaller piece of an asteroid, but I don't know how they are defined exactly.
That's so cool!https://www.nature.com/articles/d41586-020-02717-3
This is stunning, one needs to stop for a minute and take in whats being seen here and marvel at this (EHT) achievement.
Its one of the few places on earth I really want to go to. The asteroid was only 46 meters in size!Cheers. I've been to the Meteor Crater in Arizona and it was absolutely massive.
Isn't it! We're very lucky in my opinion.That's so cool!
Can't wait for the Webb Telescope to launch. I'm certain we'll discover many wonderous things.Isn't it! We're very lucky in my opinion.
If it ever does!Can't wait for the Webb Telescope to launch. I'm certain we'll discover many wonderous things.
Really hope so, would be such an achievement. Also an important tool for further exploration.If it ever does!
Its actually scary how massive the place is. There's a viewing observatory that allows you to actually stand on top of the crater from very high up. Apparently the NASA moon landing astronauts used the crater to simulate the moon's surface before the mission.Its one of the few places on earth I really want to go to.

Its taking forever isn't it. I'm so nervous something will go wrong, would be devastated.Can't wait for the Webb Telescope to launch. I'm certain we'll discover many wonderous things.
A lot has been invested in the project so I'm confident it will be launched, hopefully without glitches.Its taking forever isn't it. I'm so nervous something will go wrong, would be devastated.
Me to i meant during and after launch.A lot has been invested in the project so I'm confident it will be launched, hopefully without glitches.
Yeah, going to be a nervous launch and wait until we hopefully get to see the first imagesMe to i meant during and after launch.
I have not read that book. But Fred Hoyle was a firm believer in the universe being constant and never changing. And interestingly, when Hubble discovered that all of the galaxies were moving apart, leading to the conclusion that our universe was expanding and therefore must have had a beginning, it was Hoyle who is credited with the words Big Bang.Has anyone read Fred Hoyle "The nature of the universe"? I picked this book up for 10p from a university library but never got around to reading it. Is it any good?
