"If that were true, we'd be in big trouble given the gravitational pulls on Earth, Mars, and our moon!" the NASA website states. The total lunar eclipse, in which the moon will appear red, also called Blood Moon, will be visible from 1 am to 2:43 am tonight. But fret not, as in this technology-driven world, watching the night skies is no problem even if your view of the eclipse is not as clear as you would want it to be. That's because some light from the sun bends around the edge of the Earth where the blue and green wavelengths are scattered by our atmosphere.
"From that point onwards, the shadow of the Earth will slowly retreat across the lunar surface until the partial eclipse comes to completion".
The areas of our planet from which this can be experienced are very limited, because the total lunar eclipse must be ongoing at the time of moonset/sunrise. The longest "blood moon" this century will be closely tracked by Mars through the sky in a double celestial treat of a kind that will not be repeated for decades.
He said that the occurrence necessitated the need for scientists to continue monitoring and exploring the dynamics of the motion and the phenomena associated with them.
Grab your telescope and don't miss out the rare chance to witness the longest lunar eclipse of the 21st century in the early hours of July 28.
Because the Moon is far away from Earth relatively speaking - its orbit is an ellipse, so it moves closer and further and looks larger and smaller from Earth.
There are solar and lunar eclipses, which occur in multiple ways.
‘Blood moon’: How to watch longest total lunar eclipse of the century
In east Africa: the partial eclipse will begin at 9.30pm EAT, with the moon completely red between 10.30pm and 12.13am.
Mars is reaching its opposition, when it's in alignment on the opposite side of the Earth and the sun.
Prof O'Brien explained that people in the United Kingdom would "need to have a clear south-eastern horizon as the Moon comes up" in order to see it. It's when the eclipsed Moon can be seen on one horizon, while the rising Sun can also be observed near the opposite horizon.
Social media is already flooded with excited Europeans exclaiming at the wondrous sight as the glow get brighter and redder ever night, as only red and yellow light can pass through the Earth's atmosphere.
The weather forecast for tomorrow is now predicting patchy cloud but due to the length of this eclipse most people should be able to catch a glimpse at the very least.
If you don't want to tune in for the whole show, I suggest watching just before 3:30.
