Lyrid Meteors from the Constellation Lyra
12.05.2020

Where are all of these meteors coming from? In terms of direction on the sky, the pointed answer is the constellation of Small Harp (Lyra). That is why the famous meteor shower that peaks every April is known as the Lyrids -- the meteors all appear to came from a radiant toward Lyra.

APOD: 2023 December 19 Б NGC 1499: The California Nebula
19.12.2023

Could Queen Calafia's mythical island exist in space? Perhaps not, but by chance the outline of this molecular space cloud echoes the outline of the state of California, USA. Our Sun has its home within the Milky Way's Orion Arm, only about 1,000 light-years from the California Nebula.

A December Summer Night
23.12.2023

Colours of a serene evening sky are captured in this 8 minute exposure, made near this December's solstice from New Zealand, southern hemisphere, planet Earth. Looking south, star trails form the short concentric arcs around the rotating planet's south celestial pole positioned just off the top of the frame.

The Stars of NGC 1705
23.04.2003

Some 2,000 light-years across, NGC 1705 is small as galaxies go, similar to our Milky Way's own satellite galaxies, the Magellanic Clouds. At a much larger distance of 17 million light-years...

NGC 6791: An Old, Large Open Cluster
12.01.2000

NGC 6791 is one of the oldest and largest open clusters of stars known. But how did it get so dirty? Open star clusters usually contain a few hundred stars each less than a billion years old.

IC 1795: The Fishhead Nebula
23.12.2014

To some, this nebula looks like the head of a fish. However, this colorful cosmic portrait really features glowing gas and obscuring dust clouds in IC 1795, a star forming region in the northern constellation Cassiopeia.

When Gemini Sends Stars to Paranal
13.12.2015

From a radiant point in the constellation of the Twins, the annual Geminid meteor shower rain down on planet Earth. Tonight, the Geminds reach their peak and could be quite spectacular. The featured blended image, however, captured the shower's impressive peak in the year 2012.

The Eagle and The Swan
24.08.2017

The Eagle Nebula and the Swan Nebula span this broad starscape, a telescopic view toward the Sagittarius spiral arm and the center of our Milky Way galaxy. The Eagle, also known as M16, is at top and M17, the Swan, at bottom of the frame showing the cosmic clouds as brighter regions of active star-formation.

Pan STARRS Across the Sky
5.04.2019

This astronomical sky spanning view is a mosaic from the Pan-STARRS observatory. The images were recorded with its 1.8 meter telescope at the summit of Haleakala on planet Earth's island of Maui. In fact, Earth's north celestial pole is centered in this across-the-sky projection.

Cygnus: Bubble and Crescent
17.10.2020

These clouds of gas and dust drift through rich star fields along the plane of our Milky Way Galaxy toward the high flying constellation Cygnus. Caught within the telescopic field of view are the Soap Bubble (lower left) and the Crescent Nebula (upper right).
