Very cool images of Neptune from the Webb telescope

New Webb Image Captures Clearest View of Neptune’s Rings in Decades - NASA

NASA’s James Webb Space Telescope shows off its capabilities closer to home with its first image of Neptune. Not only has Webb captured the clearest view of this distant planet’s rings in more than 30 years, but its cameras reveal the ice giant in a whole new light.

Nasa launches most ambitious, complex and expensive telescope in history.

Evertonian: crap that lad.

I can't believe they built a billion dollar mirror before Kim Kardashian

Shimmering 'Lakes' Under The South Pole of Mars Might Be Something Else Entirely

Bit disappointing if true, like the article says more research needed though.

DART was successful in altering the orbit. If you want to see something a bit fun type “nasa dart” into Google. Only tried on my phone on Chrome but might work on other browsers

Nasa's Dart spacecraft 'changed path of asteroid'

Smashing a probe into threatening space rocks is a strategy to defend Earth, an experiment confirms.

Good evening wizard how are you doing tonight.

On the Apollo 11 mission, during the landing back to Earth where there is an audio blackout with the crew, is there is a video blackout as well?

In the Apollo 11 Documentary there's film footage just as it enters Earth's atmosphere and then when the audio blackout occurs it is edited as if there is a visual blackout. I just wondered if that was for Documentary reasons only (for drama value) or a genuine technical issue due to a visual blackout happening.

Also (on a side note) how were the cameras so stable during re entry (before it cuts off and they don't show any further footage) as I thought re entry was quite violent?

BTW, I'm not a conspiracy theorist with the above questions, just asking from a technical/filming point of view if anyone can answer as I've just watched the Apollo 11 Documentary from 2019.

Was because the RS were kicking off at 3pm mate. Broadcasting blackout.

Astronomers have discovered what caused Betelgeuse's dimming in 2019 | BBC Sky at Night Magazine

Three years ago, observers watched as red giant star Betelgeuse dimmed, then brightened. Now astronomers say they've discovered why.

Betelgeuse Blew Its Top: Hubble Sees Red Supergiant Star ‘Bouncing’ After Catastrophic Upheaval

A surface mass ejection (SME) from Betelgeuse was 400 billion times more powerful than observed from the Sun.

Ok can someone explain this.... I can't wrap my tiny brain around it...
We are seeing this, but not really? It's 600 million light years from Earth so are we are seeing this from 600 million years ago?

So they are saying its about to go Supernova and be as bright as the moon... within the the next 10,000 years.
But we can only see it as looked 600 million years ago? So it's long, long dead. It actually would have exploded when the Dinosaurs were around?

500 - 600 light years, so the explosion seen in 2019 would have occurred sometime between 1419-1519 AD.

Mind melting stuff space.

It’s probably already gone supernova

So say if it goes off today then... we'll see it in say 500 years? OK so say if the James Webb or Hubble was looking at it, its the same?

Can a telescope see it real time?

No, it's looking back in time as well. The further away it looks, the further back in time it's seeing. Pretty mind bending stuff.

The light takes the same amount of time to get to us whether we look from a telescope or not. Webb/Hubble can see a lot more of the light that reaches Earth, but they don't see it any sooner.

No as others said it is irrespective of whether its by an eye or a telescope. Just a matter of how long the light takes to reach us, so if the sun completely vanished we would still see its light for 8 minutes.
