The Cygnus Loop

15,000 years ago a star in the constellation of Cygnus exploded -- the shockwave from this supernova explosion is still expanding into interstellar space! The collision of this fast moving wall of gas with...

Moon Rays Over Thurso Castle
18.05.2009

What's happening over that castle? While waiting for the Moon to rise last month in Thurso, Scotland, amateur astrophotographer Stewart Watt took a three minute exposure of the background stars. The above image was the surprising result.

A Perseid Aurora
21.08.2000

Just after the Moon set but before the Sun rose in the early morning hours of August 12, meteors pelted the Earth from the direction of the constellation Perseus, while ions pelted the Earth from the Sun.

Wisps of the Veil Nebula
4.02.2003

These wisps of gas are all that remain visible of a Milky Way star. Many thousands of years ago that star exploded in a supernova leaving the Veil Nebula, pictured above. At the time...

M78: Stardust and Starlight
4.11.2005

Interstellar dust clouds and bright nebulae abound in the fertile constellation of Orion. One of the brightest, M78, is just below center in this sharp widefield view, covering an area north of Orion's belt. At a distance of about 1,500 light-years, the bluish nebula itself is about 5 light-years across.

NGC 7841: The Smoke Nebula in Frustriaus
1.11.2013

NGC 7841 is probably known as the Smoke Nebula, found in the modern constellation of Frustriaus, the frustrated astrophotographer. Only a few light-nanoseconds from planet Earth, The Smoke Nebula is not an expanding supernova remnant along the plane of our Milky Way galaxy, though it does look a lot like one.

Helping Hand in Cassiopeia
8.11.2024

Drifting near the plane of our Milky Way galaxy these dusty molecular clouds seem to extend a helping hand on a cosmic scale. Part of a local complex of star-forming interstellar clouds they include LDN 1358, 1357, and 1355 from American astronomer Beverly Lynds' 1962 Catalog of Dark Nebulae.

An Annotated Leonid
11.11.2001

The 1998 Leonids Meteor Shower was one of the most photographed meteor event in history. Patient observers saw bright meteors streak across dark skies every few minutes, frequently leaving fading trails stretching across the sky. High above the Anza-Borrego Desert, a meteor was photographed streaking up from the radiant constellation of the Leonids: Leo.

Globular Cluster 47 Tucanae
19.09.1997

Stars come in bunches. Of the over 200 globular star clusters that orbit the center of our Milky Way Galaxy, 47 Tucanae is the second brightest globular cluster (behind Omega Centauri). Known to some affectionately as 47 Tuc or NGC 104, it is only visible from the Southern Hemisphere.
