A Graveyard of Stars

Remains of many dead and dying stars
in a vast graveyard near the center
of our Milky Way galaxy in a
black hole where the dead feed on
others – like celestial zombies emitting X-ray howls.

Watching the International Space Station Overhead

The third brightest object in the sky

tonight is the International Space Station.

Precisely at 5:37pm, one minute, above South-Southwest.

If only my world was as predictable,

my orbit stable, looking down on this.

Earthrise In Earthshine

Before daybreak these mornings, two bright objects
of nighttime, Moon and Venus, are East.
Earthshine’s glow lights the Moon’s dark side
with this twice-reflected sunlight and Earth appears
a half-lighted landscape in the lunar sky.

 

Earthrise

This NASA photograph from Apollo 11 shows the partly-illuminated Earth rising over the lunar horizon. The Earth is approximately 400,000 km away.

It’s Raining Diamonds

Voyager visited finding storms, a cyclonic

Great Dark Spot. Your biggest moon, Triton,

is a captured dwarf planet. Carbon squeezed 

out of methane mixes with water, creating

crystallized carbon. It’s raining diamonds on Neptune.

The Death of Cassini

 

The 13-year-old spacecraft sends us its final

photographs of the rings and Titan moon,

as it is steered toward Saturn’s surface.

At 76,000 mph, the atmosphere will tear

it apart and vaporize this celestial explorer.

 

Cassini–Huygens, or more commonly, Cassini, was a Flagship-class unmanned robotic spacecraft which was planned, built, launched, and operated in collaboration between NASA, the European Space Agency, and the Italian Space Agency, and was sent to the planet Saturn. Cassini was the fourth space probe to visit Saturn and the first to enter its orbit. It studied the planet and its many natural satellites from when it entered orbit in 2004[5] to when it began its final, suicide descent in September 2017.

The spacecraft was steered to its death when its fuel had been expended so that it would not crash into one of Saturn’s moons and possibly contaminate it with materials from Earth.

Giovanni Domenico Cassini (8 June 1625 – 14 September 1712) was an Italian mathematician, astronomer, astrologer and engineer who discovered four satellites of the planet Saturn and noted the division of the rings of Saturn.
