This picture is wrong as the ship will have at this moment of the descent only 4 of its 8 motors working (the external ones) in order to avoid burning the rover.

Re: APOD: The Dance of Venus and Earth (2020 Jun 03)

Finally Venus is like a moon of the Earth.

As tidal forces varie like 1/D^3 maybe when Earth is very close it is stronger than the Sun.

Re: APOD: A Starry Night of Iceland (2020 Jan 05)

Hi, Is this sky circle polar centered ? TY, Manu No. The auroral oval is defined in a complex way by the interaction between the Earth's magnetic field and charged particles from the Sun. The oval is always offset from the magnetic pole towards the night side of the Earth. In this image, we're only...

Re: APOD: Meteor Misses Galaxy (2019 Apr 30)

Not only red and green but the same red and the same green and nothing out of these red and green.

A spectral analysis would have put me right.

Seems like this meteor is ionizing the same gases as solar wind does.

My bet it is going from left to right :P

Re: APOD: Meteor Misses Galaxy (2019 Apr 30)

It is, in fact, not something that can be reliably determined from the information contained in the image. It's unlikely the imager would be able to answer the question, unless he actually observed this, which I doubt. The color information is ambiguous, given the broadband filters and the fact tha...

Re: APOD: Meteor Misses Galaxy (2019 Apr 30)

So nobody can confirm that this meteor is going from left to right. Just a lot of bla bla bla... It's a great question. I was hoping our forum contributors who have meteor expertise would give an answer. Unless it is truly something nobody can discern from a meteor track, which I very much doubt. I...

Re: APOD: Meteor Misses Galaxy (2019 Apr 30)

Meteor is going left to right if I compare with auroras, red is high and green is lower altitude.

Am I right ?

Smaller than the shadow by a factor of 2.5.
Thank you :wink:

We need an artist view corresponding of this image with more detailed explanations.
