Tentacles of the Tarantula Nebula
18.05.2010

The largest, most violent star forming region known in the whole Local Group of galaxies lies in our neighboring galaxy the Large Magellanic Cloud (LMC). Were the Tarantula Nebula at the distance of the Orion Nebula -- a local star forming region -- it would take up fully half the sky.

Milky Way Rising

How far can you see? Everything you can see, and everything you could possibly see, right now, assuming your eyes could detect all types of radiations around you -- is the observable universe. In visible...

A Treasure Chest in the Carina Nebula

This treasure chest is full of stars. The featured image was obtained with NASA's James Webb Space Telescope and shows a dust pilar in the Carina Nebula inside our Galaxy, roughly 7500 light-years away.

X Rays from the Galactic Core
8.01.2003

Using the orbiting Chandra X-ray Observatory, astronomers have taken this long look at the core of our Milky Way galaxy, some 26,000 light-years away. The spectacular false-color view spans about 130 light-years.

NGC 1 and NGC 2
19.08.2005

Beautiful nebulae, clusters, and galaxies that grace planet Earth's night sky are often known by their New General Catalog designation or NGC number. That classic listing was compiled by John Louis Emil Dreyer, remarkable director of the Armagh Observatory from 1882 to 1916.

GRB 980703: A Reassuring Redshift
13.07.1998

In the old days, just over a year ago, astronomers had little idea of the true distance to gamma-ray bursts. Did these enigmatic explosions occur in our outer Galaxy, or in the outer Universe?

X Ray Rings Around a Gamma Ray Burst
17.10.2022

Why would x-ray rings appear around a gamma-ray burst? The surprising answer has little to do with the explosion itself but rather with light reflected off areas of dust-laden gas in our own Milky Way Galaxy.

47 Tuc Near the Small Magellanic Cloud
6.12.2012

Globular star cluster 47 Tucanae is a jewel of the southern sky. Also known as NGC 104, it roams the halo of our Milky Way Galaxy along with around 200 other globular star clusters.
