Planetary and Lunar Coordinates

This book provides low to medium-precision positions of the Sun, Moon and planets for the purpose of planning observations. It also includes information on the elongation and magnitudes of the planets, eclipses, moon phases and a wide variety of astronomical phenomena. The eclipse section has been enhanced to present the data for both solar and lunar eclipses in graphical form. There are two versions of this publication. Status: The 2001-2020 UK edition is available from The Stationery Office. Errata: Page A1, 7th line: for 25 hours read 24 hours. Image Gallery: Cassini & Other NASA Outer Solar System Missions. Picture of the Week. In this new Hubble image, we can see an almost face-on view of the galaxy NGC 1084.

Picture of the Week

At first glance, this galaxy is pretty unoriginal. Like the majority of galaxies that we observe it is a spiral galaxy, and, as with about half of all spirals, it has no bar running through its loosely wound arms. However, although it may seem unremarkable on paper, NGC 1084 is actually a near-perfect example of this type of galaxy — and Hubble has a near-perfect view of it. NGC 1084 has hosted several violent events known as supernovae — explosions that occur when massive stars, many times more massive than the Sun, approach their twilight years.

As the fusion processes in their cores run out of fuel and come to an end, these stellar giants collapse, blowing off their outer layers in a violent explosion. Astronomers have noted five supernova explosions within NGC 1084 over the past half century. Photojournal: NASA's Image Access Home Page. The Day the Earth Smiled. On July 19, 2013, in an event celebrated the world over, NASA's Cassini spacecraft slipped into Saturn's shadow and turned to image the planet, seven of its moons, its inner rings -- and, in the background, our home planet, Earth. With the sun's powerful and potentially damaging rays eclipsed by Saturn itself, Cassini's onboard cameras were able to take advantage of this unique viewing geometry. They acquired a panoramic mosaic of the Saturn system that allows scientists to see details in the rings and throughout the system as they are backlit by the sun.

This mosaic is special as it marks the third time our home planet was imaged from the outer solar system; the second time it was imaged by Cassini from Saturn's orbit; and the first time ever that inhabitants of Earth were made aware in advance that their photo would be taken from such a great distance. This image spans about 404,880 miles (651,591 kilometers) across. For more information about the Cassini Solstice Mission visit and. NASA image service. Images.

About the Kavli Prize. “The Kavli Prizes recognize three scientific areas we believe are exceptionally exciting in the 21st Century and at the brink of remarkable discoveries – astrophysics, nanoscience and neuroscience.

About the Kavli Prize

Created to honor, support and recognize scientists whose work have had a profound impact in these areas, through these Prizes we also hope to raise people's awareness of the benefits of basic science in their own lives.
