In a gravity-free environment, flames tend to be spherical, unlike the teardrop shape seen on Earth.
This is because the absence of gravity prevents the hot gases from rising, which normally creates the teardrop shape.
Seven Planets to Line Up in Just 3 Days
A planetary parade will take place on February 28, with Saturn, Mercury, Neptune, Venus, Uranus, Jupiter, and Mars all lining up in the evening sky. This combination will not happen again this decade.
Four of them (Mercury, Venus, Jupiter, and Mars) will be visible to the naked eye, while Uranus and Neptune will require binoculars or a telescope. Saturn will be the hardest to see due to its proximity to the Sun at this time.
To observe this event, it is recommended to choose a location with minimal light pollution and clear skies. The planets will appear just after sunset.
