Markarian's Chain to Messier 64

Top to bottom, this colorful and broad telescopic mosaic links Markarian's Chain of galaxies across the core of the Virgo Cluster to dusty spiral galaxy Messier 64. Galaxies are scattered through the field of view that spans some 20 full moons across a gorgeous night sky. The cosmic frame is also filled with foreground stars from constellations Virgo and the well-groomed Coma Berenices, and faint, dusty nebulae drifting above the plane of the Milky Way. Look carefully for Markarian's eyes. The famous pair of interacting galaxies is near the top, not far from M87, the Virgo cluster's giant elliptical galaxy. At the bottom, you can stare down Messier 64, also known as the Black Eye Galaxy. The Virgo Cluster is the closest large galaxy cluster to our own local galaxy group. Virgo Cluster galaxies are about 50 million light-years distant, but M64 lies a mere 17 million light-years away.

Visualization of the August 21, 2017 Total Solar Eclipse
Still image showing the Earth, moon, and sun aligned during solar eclipse

On August 21, 2017, the Earth will cross the shadow of the moon, creating a total solar eclipse. Eclipses happen about every six months, but this one is special. For the first time in almost 40 years, the path of the moon's shadow passes through the continental United States. This visualization shows the Earth, moon, and sun at 17:05:40 UTC during the eclipse.

In the animation from which this still was taken, the Earth, moon, sun, and shadow cones are viewed through a telescopic lens on a virtual camera located far behind the Earth. Long focal lengths like the one used here appear to compress the distance between near and far objects.

Despite appearances, the geometry of the scene is correct. The moon's umbra cone is roughly 30 Earth diameters long, barely enough to reach the Earth, while the sun is almost 400 times farther away.

The total solar eclipse crossing the continental United States on Aug. 21, 2017 provides a brilliant sight in the daytime sky and a rare chance for scientists to collect data only available during eclipses. Learn more: http://go.nasa.gov/2ttJ60S
