The Mysterious Rings of Supernova 1987A
26.02.2012

What's causing those odd rings in supernova 1987A? Twenty five years ago, in 1987, the brightest supernova in recent history was seen in the Large Magellanic Clouds. At the center of the above picture is an object central to the remains of the violent stellar explosion.

Supernova Remnant: Cooking Elements In The LMC
9.05.1996

Massive stars cook elements in their cores through nuclear fusion. Starting with the light elements of hydrogen and helium, their central temperatures and pressures produce progressively heavier elements, carbon, oxygen, nitrogen, etc. up through iron.

Henize 70: A Superbubble in the LMC
29.11.1999

Massive stars -- upwards of 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 on the compositions and locations of future generations of stars and star systems.

APOD: 2025 September 5 Б 47 Tucanae: Globular Star Cluster
4.09.2025

Also known as NGC 104, 47 Tucanae is a jewel of the southern sky. Not a star but a dense cluster of stars, it roams the halo of our Milky Way Galaxy along with some 200 other globular star clusters.

NGC 602 in the Flying Lizard Nebula
6.03.2015

Near the outskirts of the Small Magellanic Cloud, a satellite galaxy some 200 thousand light-years distant, lies 5 million year young star cluster NGC 602. Surrounded by natal gas and dust, NGC 602 is just below center in this telescopic field of view with the angular size of the Full Moon on the sky.

Sky Lights in the New Year
1.01.2016

Triggered by the impact of a coronal mass ejection on New Year's eve, a moderate geomagnetic storm brought a celebration of sky lights to planet Earth's high latitudes yesterday. In this New Year's nightscape, the shimmering reddish curtains of aurora australis along a southern horizon are captured over Morgiana, SW Victoria, Australia.

Spiral Galaxy NGC 6744
25.05.2017

Big, beautiful spiral galaxy NGC 6744 is nearly 175,000 light-years across, larger than our own Milky Way. It lies some 30 million light-years distant in the southern constellation Pavo appearing as a faint, extended object in small telescopes. We see the disk of the nearby island universe tilted towards our line of sight.

NGC 6822: Barnard s Galaxy
27.11.2020

Grand spiral galaxies often seem to get all the glory, flaunting their young, bright, blue star clusters in beautiful, symmetric spiral arms. But small galaxies form stars too, like nearby NGC 6822, also known as Barnard's Galaxy.

NGC 206 and the Star Clouds of Andromeda
27.11.2024

The large stellar association cataloged as NGC 206 is nestled within the dusty arms of the neighboring Andromeda galaxy along with the galaxy's pinkish star-forming regions. Also known as M31, the spiral galaxy is a mere 2.5 million light-years away.
