6,500 light-years away lies the Crab Nebula, the remains of an exploded star. While this target has been well-studied by multiple observatories, including the Hubble Space Telescope, Webb’s infrared sensitivity and resolution offer new clues into the makeup and origins of this scene. via NASA https://ift.tt/XUrSd2c

Named for the southern constellation toward which most of its galaxies can be found, the Fornax Cluster is one of the closest clusters of galaxies. About 62 million light-years away, it’s over 20 times more distant than our neighboring Andromeda Galaxy, but only about 10 percent farther along than the better known and more populated […]

This nighttime view from the International Space Station shows the city lights of the northeastern United States and major urban areas including Long Island, New York; Philadelphia, Pennsylvania; and Washington, D.C. The orbital lab was soaring 262 miles above the Pine Tree State of Maine at the time of this photograph. via NASA https://ift.tt/tHmWJ13

Part of the Sun disappeared earlier this month, but few people were worried. The missing part, which included the center from some locations, just went behind the Moon in what is known as an annular solar eclipse. Featured here is an eclipse sequence taken as the Moon was overtaking the rising Sun in the sky. […]

On Sept. 7, 2023, during its 54th close flyby of Jupiter, NASA’s Juno mission captured this view of an area in the giant planet’s far northern regions called Jet N7. The image shows turbulent clouds and storms along Jupiter’s terminator, the dividing line between the day and night sides of the planet. The low angle […]

Halloween’s origin is ancient and astronomical. Since the fifth century BC, Halloween has been celebrated as a cross-quarter day, a day halfway between an equinox (equal day / equal night) and a solstice (minimum day / maximum night in the northern hemisphere). With a modern calendar however, even though Halloween occurs today, the real cross-quarter […]

This image, taken by an astronaut on the International Space Station, shows the reddish-brown waters of the Betsiboka River Delta in Madagascar. The color is caused by the transport of iron-rich sediment. via NASA https://ift.tt/oGnHxp4

Do any shapes seem to jump out at you from this interstellar field of stars and dust? The jeweled expanse, filled with faint, starlight-reflecting clouds, drifts through the night in the royal constellation of Cepheus. Far from your own neighborhood on planet Earth, these ghostly apparitions lurk along the plane of the Milky Way at […]

What’s happened to the Moon? Within the last day, part of the Moon moved through the Earth’s shadow. This happens about once or twice a year, but not every month since the Moon’s orbit around the Earth is slightly tilted. Pictured here, the face of a full Hunter’s Moon is shown twice from Italy during […]

Gamma Cassiopeiae shines high in northern autumn evening skies. It’s the brightest spiky star in this telescopic field of view toward the constellation Cassiopeia. Gamma Cas shares the ethereal-looking scene with ghostly interstellar clouds of gas and dust, IC 59 (top left) and IC 63. About 600 light-years distant, the clouds aren’t actually ghosts. They […]
