M51: The Whirlpool Galaxy

Copyright: Fabian Neyer Find the Big Dipper and follow the handle away from the dipper’s bowl until you get to the last bright star. Then, just slide your telescope a little south and west and you’ll come upon this stunning pair of interacting galaxies, the 51st entry in Charles Messier’s famous catalog. Perhaps the original […]

The Tulip and Cygnus X-1

Copyright: Peter Kohlmann Framing a bright emission region, this telescopic view looks out along the plane of our Milky Way Galaxy toward the nebula rich constellation Cygnus the Swan. Popularly called the Tulip Nebula, the reddish glowing cloud of interstellar gas and dust is also found in the 1959 catalog by astronomer Stewart Sharpless as […]

Jupiter from the Webb Space Telescope

Copyright: This new view of Jupiter is illuminating. High-resolution infrared images of Jupiter from the new James Webb Space Telescope (Webb) reveal, for example, previously unknown differences between high-floating bright clouds — including the Great Red Spot — and low-lying dark clouds. Also clearly visible in the featured Webb image are Jupiter’s dust ring, bright […]

The Horsehead Nebula Region without Stars

Copyright: George Chatzifrantzis The famous Horsehead Nebula in Orion is not alone. A deep exposure shows that the dark familiar shaped indentation, visible just right of center, is part of a vast complex of absorbing dust and glowing gas. The featured spectacular picture details an intricate tapestry of gaseous wisps and dust-laden filaments that were […]

Little Planet South Pole

Copyright: Aman Chokshi Lights play around the horizon of this snowy little planet as it drifts through a starry night sky. Of course the little planet is actually planet Earth. Recorded on August 21, the digitally warped, nadir centered panorama covers nearly 360×180 degrees outside the Amundsen-Scott South Pole Station, Antarctica. The southernmost research outpost […]

Tiangong Space Station Transits the Moon

Copyright: Lucy Yunxi Hu The rugged lunar south polar region lies at the top of this colorful portrait of a last quarter Moon made on August 20. Constructed from video frames and still images taken at Springrange, New South Wales, Australia it also captures a transit of China’s Tiangong Space Station. The transit itself was […]

The Cartwheel Galaxy from Webb

Copyright: To some, it looks like a wheel of a cart. In fact, because of its outward appearance, the presence of a central galaxy, and its connection with what looks like the spokes of a wheel, the galaxy on the right is known as the Cartwheel Galaxy. To others, however, it looks like a complicated […]

Meteor & Milky Way over the Mediterranean

Copyright: Julien Looten Careful planning made this a nightscape to remember. First, the night itself was chosen to occur during the beginning of this year’s Perseid Meteor Shower. Next, the time of night was chosen to be before the bright Moon would rise and dominate the night sky’s brightness. The picturesque foreground was selected to […]

Earth’s Recent Climate Spiral

Copyright: Is our Earth warming? Compared to the past 250 million years, the Earth is currently enduring a relative cold spell, possibly about four degrees Celsius below average. Over the past 120 years, though, data indicate that the average global temperature of the Earth has increased by nearly one degree Celsius. The featured visualization video […]

Stardust and Comet Tails

Copyright: CARA Project Heading for its closest approach to the Sun, or perihelion, on December 19 comet C/2017 K2 (PanSTARRS) remains a sight for telescopic observers as it sweeps through planet Earth’s skies in the constellation Scorpius. The comet currently sports a greenish coma, long whitish dust tail, and short ion tail in this deep […]

Saturn: 1993 – 2022

Copyright: Tunc Tezel Saturn is the most distant planet of the Solar System easily visible to the unaided eye. With this extraordinary, long-term astro-imaging project begun in 1993, you can follow the ringed gas giant for one Saturn year as it wanders once around the ecliptic plane, finishing a single orbit around the Sun by […]

Full Moon Perseids

Copyright: Juan Carlos Casado The annual Perseid meteor shower was near its peak on August 13. As planet Earth crossed through streams of debris left by periodic Comet Swift-Tuttle meteors rained in northern summer night skies. But even that night’s nearly Full Moon shining near the top of this composited view couldn’t hide all of […]

Stargate Milky Way

Copyright: Maxime Oudoux There is a huge gate of stars in the sky, and you pass through it twice a day. The stargate is actually our Milky Way Galaxy, and it is the spin of the Earth that appears to propel you through it. More typically, the central band of our Milky Way appears as […]

A Meteor Wind over Tunisia

Copyright: Makrem Larnaout Does the Earth ever pass through a wind of meteors? Yes, and they are frequently visible as meteor showers. Almost all meteors are sand-sized debris that escaped from a Sun-orbiting comet or asteroid, debris that continues in an elongated orbit around the Sun. Circling the same Sun, our Earth can move through […]

The Cygnus Wall of Star Formation

Copyright: Johan Bogaerts The North America nebula on the sky can do what the North America continent on Earth cannot — form stars. Specifically, in analogy to the Earth-confined continent, the bright part that appears as Central America and Mexico is actually a hot bed of gas, dust, and newly formed stars known as the […]
