The Asymmetric Nebula Surrounding Wolf Rayet Star 18
8.11.2022
Why does the nebula around the star WR-18 shine brighter on one side? Also known as NGC 3199, this active star and its surrounding nebula lie about 12,000 light-years away toward the nautical southern constellation of Carina.
Galaxies: Wilds Triplet from Hubble
7.11.2022
How many galaxies are interacting here? This grouping of galaxies is called the Wild Triplet, not only for the discoverer, but for the number of bright galaxies that appear. It had been assumed that...
A Total Lunar Eclipse Over Tajikistan
6.11.2022
If the full Moon suddenly faded, what would you see? The answer was recorded in a dramatic time lapse video taken during the total lunar eclipse in 2011 from Tajikistan. During a total lunar eclipse, the Earth moves between the Moon and the Sun, causing the moon to fade dramatically.
Dark Ball in Inverted Starfield
5.11.2022
Does this strange dark ball look somehow familiar? If so, that might be because it is our Sun. In the featured image from 2012, a detailed solar view was captured originally in a very specific color of red light, then rendered in black and white, and then color inverted.
Lunar Eclipse at the South Pole

Last May 16 the Moon slid through Earth's shadow, completely immersed in the planet's dark umbra for about 1 hour and 25 minutes during a total lunar eclipse. In this composited timelapse...
InSight's Final Selfie
3.11.2022
The Mars InSight lander returned its first image from the Red Planet's flat, equatorial Elysium Planitia after a successful touchdown on November 26, 2018. The history making mission to explore the martian Interior using Seismic investigations, geodesy, and heat transport has been operating for over 1,400 martian days or sols.
M33: The Triangulum Galaxy
2.11.2022
The small, northern constellation Triangulum harbors this magnificent face-on spiral galaxy, M33. Its popular names include the Pinwheel Galaxy or just the Triangulum Galaxy. M33 is over 50,000 light-years in diameter, third largest in the Local Group of galaxies after the Andromeda Galaxy (M31), and our own Milky Way.
A Partial Eclipse of an Active Sun
1.11.2022
Watch for three things in this unusual eclipse video. First, watch for a big dark circle to approach from the right to block out more and more of the Sun. This dark circle is the Moon, and the video was made primarily to capture this partial solar eclipse last week.
NGC 6357: The Lobster Nebula
31.10.2022
Why is the Lobster Nebula forming some of the most massive stars known? No one is yet sure. Cataloged as NGC 6357, the Lobster Nebula houses the open star cluster Pismis 24 near its center -- a home to unusually bright and massive stars.
