Star Clusters M35 and NGC 2158
9.05.2021

Clusters of stars can be near or far, young or old, diffuse or compact. The featured image shows two quite contrasting open star clusters in the same field. M35, on the lower left...

Globular Star Cluster NGC 6752
22.01.2020

Some 13,000 light-years away toward the southern constellation Pavo, the globular star cluster NGC 6752 roams the halo of our Milky Way galaxy. Over 10 billion years old, NGC 6752 follows clusters Omega Centauri and 47 Tucanae as the third brightest globular in planet Earth's night sky.

M13: The Great Globular Cluster in Hercules

In 1716, English astronomer Edmond Halley noted, "This is but a little Patch, but it shews itself to the naked Eye, when the Sky is serene and the Moon absent." Of course...

Blue Straggler Stars in Globular Cluster M53
6.02.2021

If our Sun were part of this star cluster, the night sky would glow like a jewel box of bright stars. This cluster, known as M53 and cataloged as NGC 5024, is one of about 250 globular clusters that survive in our Galaxy.

APOD: 2023 January 30 Б Globular Star Cluster NGC 6355 from Hubble
29.01.2023

Globular clusters once ruled the Milky Way. Back in the old days, back when our Galaxy first formed, perhaps thousands of globular clusters roamed our Galaxy. Today, there are less than 200 left. Over the eons, many globular clusters were destroyed by repeated fateful encounters with each other or the Galactic center.

Stellar Laboratories in the LMC
25.07.1997

Stars are evolving in the Large Magellanic Clouds (LMC). This is particularly evident in the above close-up of the LMC's edge, which appears about as large as the full moon. Visible only...

Henize 70: A SuperBubble In The LMC
10.05.1996

Massive stars (tens of times the mass of the Sun) profoundly affect their galactic environment. Churning and mixing the clouds of gas and dust between the stars, they leave their mark in the compositions and locations of future generations of stars and star systems.

Rampaging Supernova Remnant N63A
8.06.2005

What has this supernova left behind? As little as 2,000 years ago, light from a massive stellar explosion in the Large Magellanic Clouds (LMC) first reached planet Earth. The LMC is a close...

The LMC Galaxy in Glowing Gas
22.01.2006

What goes on inside of a galaxy? To help find out, astronomers from the Magellanic Cloud Emission Line Survey team imaged our neighboring LMC galaxy in spectacular detail and highlighted very specific colors of light emitted by glowing gas.

Palomar 6: Globular Star Cluster
18.10.2021

Where did this big ball of stars come from? Palomar 6 is one of about 200 globular clusters of stars that survive in our Milky Way Galaxy. These spherical star-balls are older than our Sun as well as older than most stars that orbit in our galaxy's disk.
