The dominant features on the Moon’s nearside – the side that always faces the Earth – are the dark maria, which early astronomers thought were seas. These lava – filled basis formed when molten rock seeped through the Moon’s crust to fill depressions left by meteorite impacts.

Filtering Starlight Shown Graphically
The color of planets depends on the spectrum of the star’s light, which astronomers can easily observe, and filtering of light by air and water, which the author and her colleagues have simulated based on the likely atmospheric composition and it’s own effects.

An Internal View of the Saturn V
When the American Space program finally achieved a Moon landing on July 20, 1969, the Apollo 11 spacecraft was launched by a powerful rocked called Saturn V. The most powerful rocker ever, Saturn V was used to launch all the Apollo Spacecraft on lunar missions.

Neuron Stars Explained
A neuron star is a sort of stellar leftover that can consequence from the gravitational breakdown of a huge star around a Sort II, Sort Ib or Sort Ic supernova occasion. Such stars are made very nearly truly out of neutrons, which are subatomic particles without electrical accuse and of a little more extensive mass than protons. Neuron stars are exceptionally sultry and are backed in opposi...

How Far are the Stars
Until 1838, Astronomers had little idea of the true size of the Universe. But in that year, Friedrich Bessel used a technique called the parallax method to make the first successful measurement of the distance to a star. Modern astronomers have many different ways of figuring out how far away an object is, but they all depend ultimately on the parallax method. As the Earth orbits the S...

What Gravity does to Entropy
What qualifies as low entropy or high entropy depends on the situation. Physicists identify the high – entropy state of a system based on how the system evolves over time. For example, if a diffuse and sufficiently cool gas feels the tug of gravity, it evolves to a clump. The law of entropy increase then implies that the clump has high entropy, even though at first glance it might appear to be...
