Assuming that protons do not decay, the estimated time for rigid objects, from free-floating rocks in space to planets, to rearrange their atoms and molecules via quantum tunnelling. On this timescale, any discrete body of matter "behaves like a liquid" and becomes a smooth sphere due to diffusion and gravity. [144] 1.16×10 67 (11.6 ...
Fog is a visible aerosol consisting of tiny water droplets or ice crystals suspended in the air at or near the Earth's surface. [1] [2] Fog can be considered a type of low-lying cloud usually resembling stratus and is heavily influenced by nearby bodies of water, topography, and wind conditions.
No longer scattered by free electrons, the photons were ("decoupled") and propagated freely. This vast collection of photons from the earliest times of the universe can still be detected today as the cosmic microwave background (CMB). [5]: 22.4.3 This is the oldest direct observation we currently have of the universe.
NASA released a timelapse video that shows the eye of Hurricane Milton as seen from the International Space Station orbiting 275 miles above Earth.
An event in the universe is caused by the set of events in its causal past. An event contributes to the occurrence of events in its causal future. Upon choosing a frame of reference, one can assign coordinates to the event: three spatial coordinates x → = ( x , y , z ) {\displaystyle {\vec {x}}=(x,y,z)} to describe the location and one time ...
Meteor showers occur when Earth’s orbit around the Sun takes it through the dust left behind by a comet. The Earth sweeps up the dust like a car speeding through a cloud of insects on the highway.
A graphical view of the Cosmic Calendar, featuring the months of the year, days of December, the final minute, and the final second. The Cosmic Calendar is a method to visualize the chronology of the universe, scaling its currently understood age of 13.8 billion years to a single year in order to help intuit it for pedagogical purposes in science education or popular science.
From liquid oceans on Pluto, to a mysterious whistling sound detected outside our atmosphere, here's everything important that happened in space last week. This week in space: 6/22 - 6/29 Skip to ...
