Waves of the Great Lacerta Nebula

It is one of the largest nebulas on the sky -- why isn't it better known? Roughly the same angular size as the Andromeda Galaxy, the Great Lacerta Nebula can be found toward the constellation of the Lizard (Lacerta).
A Long Snaking Filament on the Sun
12.09.2022
Earlier this month, the Sun exhibited one of the longer filaments on record. Visible as the bright curving streak around the image center, the snaking filament's full extent was estimated to be over half of the Sun's radius -- more than 350,000 kilometers long.
Red Sprite Lightning over the Czech Republic

Planets of the Solar System: Tilts and Spins
10.09.2022
How does your favorite planet spin? Does it spin rapidly around a nearly vertical axis, or horizontally, or backwards? The featured video animates NASA images of all eight planets in our Solar System to show them spinning side-by-side for an easy comparison.
Galaxy by the Lake

This 180 degree panoramic night skyscape captures our Milky Way Galaxy as it arcs above the horizon on a winter's night in August. Near midnight, the galactic center is close to the zenith with the clear waters of Lake Traful, Neuquen, Argentina, South America, planet Earth below.
Interstellar Voyager
8.09.2022
Voyager 1 and Voyager 2 were launched in 1977 on a grand tour of the outer planets of the Solar System. They have become the longest operating and most distant spacecraft from Earth. Both have traveled beyond the heliosphere, the realm defined by the influence of the solar wind and the Sun's magnetic field.
North America and the Pelican
7.09.2022
Fans of our fair planet might recognize the outlines of these cosmic clouds. On the left, bright emission outlined by dark, obscuring dust lanes seems to trace a continental shape, lending the popular name North America Nebula to the emission region cataloged as NGC 7000.
Tarantula Stars R136 from Webb
6.09.2022
Near the center of a nearby star-forming region lies a massive cluster containing some of the largest and hottest stars known. Collectively known as star cluster NGC 2070, these stars are part of the vast Tarantula Nebula and were captured in two kinds of infrared light by the new Webb Space Telescope.
An Iridescent Pileus Cloud over China
5.09.2022
Yes, but how many dark clouds have a multicolored lining? Pictured, behind this darker cloud, is a pileus iridescent cloud, a group of water droplets that have a uniformly similar size and so together diffract different colors of sunlight by different amounts. The featured image was taken last month in Pu'er, Yunnan Province, China.
