How did you mount the camera on the telescope to take the picture?

Reply to comment by UHF1211 in Asteroids sudden flyby shows blind spot in planetary threat detection by coinfanking
My understanding is that the steam released from the flash boiling of water vapour in the rock would be enough to push an asteroid off course enough. As long as it was sufficiently far away.

Infinitesimal chance of rocket exploding that could never even set off the nuclear chain reaction, vs possible planet killing asteroid impact.🤔

They would switch back and forth between multiple photos of the same spot. Makes it way easier to see differences. Although I do believe he went through hundreds, if not thousands of images looking for a tiny dot moving.

Reply to comment by FunctionFluffy4932 in PNW Winter Moon. Taken with my Canon M100 and 200mm zoom lens. by FunctionFluffy4932
I quite like it personally. There are "clean" BW photos of the moon everywhere, but this one looks kind of unique. It also looks like it's an analog picture taken a long time ago with some very expensive piece of equipment at the time, but you can say you actually took it with your handheld mirrorless!

I'm good with that. But I don't know how to calculate it so I'm counting on THEM.

Reply to comment by smilingpike31 in What if our sun was a part of another constellation on another planet? by smilingpike31
It does radiate energy in all directions, but the material in the sun is rotating, so it necessarily has an axis of rotation. The rotation has other effects, like twisting the sun’s magnetic field into a spiral.

Two ads later and I ditched without seeing the content lol. I'll have to take your word for it.

V formations can be aircraft prototypes. The likes of Lockheed and Boeing have been trying to get the flying wing design to work on small aircraft for decades.

Wait does it even matter if the sun is on an axis? Well it does create an energy source for every direction so does it matter for it to have an axis?

The current space race is the only reason the SLS finally got off the ground.

So you are not offsetting planet rotation, if not that could be why the detail is not there. Images look well aligned for it.

If we can discover an asteroid when it's nearing its apoapsis, it's slowest highest point in its orbit.. and if it can be predicted to be on course to impact Earth..and if we have a defensive impactor rocket somewhere out there on standby... and if we can get to the asteroid quick enough... it would only take a tiny little bump to knock it tens of thousands of kms off course. That's a lot of ifs.. but I think we're only a few decades away from having a somewhat effective chance at preventing an ELE.

It's a 16 second video of a small dott. That's the most bullshit clickbait I've ever seen for space related content.

Fun fact: the astronauts choose their own "regular" underwear to wear beneath that garment. by DweadPiwateWoberts
Pretty sure it's the green suit, although in the pictures I've seen, it's blue and looks slightly different. The white part is the Thermal Micrometeroid Garment - it's mainly for rejecting as much heat as possible and for protecting the airtight suit from pokey hazards (as well as micrometeoroids).

Is there any tutorial for that?? I'd like to learn about it. I have treated this similar to any other galaxy and went on to stack them
