Lose yourself in the glorious star fields of the Milky Way. Astronomers at the Ruhr-Universität Bochum (RUB) have compiled the largest astronomical image ever made and released it to the general public.

The full image is a mosaic of 268 individual images. It is contained in a single data file of 194 Gigabytes. Made up of 46 billion pixels, it is so huge that the astronomers have provided an online tool to help view it.

The tool allows users to navigate around, zoom in and out, and explore the depths of space. It takes a while to load the zoomed images even with a good broadband connection but the rewards are worth it. What appear like smudges at one scale resolve into jewel-box star clusters at the deeper level.

A text box shows the coordinates of the image on display but can also be used to show specific celestial objects. For example, type in ‘Eta Carinae’ to see the explosive aftermath of this unstable star, or the Messier catalogue number (listed here) of an object in the Milky Way to be taken straight there.

The image is the result of five years monitoring the night sky using the telescope at the university’s observatory in the Atacama Desert in Chile. The monitoring programme has allowed astronomer Moritz Hackstein and other researchers to discover 50,000 previously unknown variable celestial objects.

These variations could be the result of planets passing infant of stars or multiple star systems where stars obscure each other every now and then. They are now being studied up to understand their behaviour.

The Milky Way itself is the misty band of light that runs across the sky. It is visible from dark sites well away from street lights. In 1610, Galileo raised his newly built telescope to the sky and sparked an astronomical revolution by showing that the Milky Way was made of the combined light of many distant stars. Now you can do something similar by visiting the website and zooming in.

Stuart Clark’s latest book is The Unknown Universe (Head of Zeus).

Comet Catalina has two tails


earthsky.org/space/comet-catalina-c2013-us10-november-december-january-2015-2016

UPDATE NOVEMBER 23, 2015: Comet C/2013 US10 (Catalina) is finally here and – for telescopic viewers – it’s showing two tails! Several observers in recent days have spotted it on film. An avalanche of pictures is expected during the next days as Comet Catalina ascends in the predawn sky and becomes brighter and easier to see. Current magnitude estimates ranges between 7.6 to 6 (the limit of viewing with the unaided eye). And the comet is still brightening.

Most comets do show two tails: a dust tail and a plasma tail of ionized gas. These tails point away from the sun and are usually not related to the direction of travel. Instead, the tails are related to how the gases and dust react to solar heat.

Comet Catalina was closest to the sun on November 15, so it is still difficult to observe because of its nearness to the horizon just before sunrise. The hope is that the comet will brighten enough to become visible from the eye from a dark site, by the end of November, as it moves higher in the eastern, predawn sky. A higher position in the sky will provide a better contrast. The observations made early this week will provide a good idea of its brightness, to see if it’s improving or not. By the end of this month, Comet Catalina might be visible to the eye at a visual magnitude of 5 or 6, which means it would be within the limit for viewing with the unaided eye from dark sky sites. It’ll be in the predawn sky, near the planets and moon in early December. Comets have been shown to be unpredictable, so it may become brighter or fainter. Sometimes comets even disintegrate. But this comet is well worth following! Follow the links below to learn more – and check back to this post periodically. We’ll provide updates.

When and where should I begin to look?

What will Comet Catalina look like?

Here are some important dates

When is the next predicted comet visible to the eye alone?

i was looking for sites on night skies and light pollution.
glad to have found them.
will perhaps get back here for discussion on this topic.

meanwhile, this is for my inner child's memory whatnot.
feel free to share your associations, as well.

peace and love to all.
