Spanning light-years, this suggestive shape known as the Seahorse Nebula floats in silhouette against a rich background of of stars and glowing hydrogen gas. Seen toward the royal northern constellation of Cepheus, the dusty, dark nebula is part of a Milky Way molecular cloud some 1,200 light-years distant. It is also listed as Barnard 150 (B150), one of 182 dark markings of the sky cataloged in the early 20th century by astronomer E. E. Barnard. Packs of low-mass stars are forming within, but their collapsing cores are only visible at long infrared wavelengths. Still, the luminous depths of the Milky Way in Cepheus add to this stunning galactic skyscape.

Taken on July 29 and July 30, a registered and stacked series of exposures creates this dreamlike view of a northern summer night. Multiple firefly flashes streak across the foreground as the luminous Milky Way arcs above the horizon in the Sierra de Órganos national park of central Mexico, The collection of bright streaks aligned across the sky toward the upper left in the timelapse image are Delta Aquariid meteors. Currently active, the annual Delta Aquarid meteor shower shares August nights though, overlapping with the better-known Perseid meteor shower. This year that makes post-midnight, mostly moonless skies in early August very popular with late night skygazers. How can you tell a Delta Aquariid from a Perseid meteor? The streaks of Perseid meteors can be traced back to an apparent radiant in the constellation Perseus. Delta Aquariids appear to emerge from the more southerly constellation Aquarius, beyond the top left of this frame. Of course, the bioluminescent flashes of fireflies are common too on these northern summer nights. But how can you tell a firefly from a meteor? Just try to catch one.

A volcano is shown with its peak in the midst of purple clouds. Lightning appears to come out of the top of the volcano in multiple paths into the upper sky. Please see the explanation for more detailed information.

This stunning portrait of NGC 5335 was captured by the Hubble Space Telescope. Some 170,000 light-years across and over 200 million light-years away toward the constellation Virgo, the magnificent spiral galaxy is seen face-on in Hubble's view. Within the galactic disk, loose streamers of star forming regions lie along the galaxy's flocculent spiral arms. But the most striking feature of NGC 5335 is its prominent central bar. Seen in about 30 percent of galaxies, including our Milky Way, bar structures are understood to channel material inward toward the galactic center, fueling star formation. Of course, distant background galaxies are easy to spot, scattered around the sharp Hubble image. Launched in 1990, Hubble is now celebrating its 35th year exploring the cosmos from orbit around planet Earth.

How to see the 'blood worm moon' total lunar eclipse tonight The "blood worm moon," so named for the reddish hue of its glow and the time of year it's occurring, will be visible in every U.S. state.

The “blood worm moon,” so named for the reddish hue of its glow and the time of year it’s occurring, will be visible in every U.S. state.

The starry image filled with a red glow features a red, yellow, and blue colored nebula. The nebula has, roughly, the shape of the US state of California. Please see the explanation for more detailed information.

Trump Falsely Suggests Ukraine Is to Blame for the War: What to Know A look at how the war in Ukraine began, the state of the peace talks and why the country isn’t holding elections.

President Trump on Tuesday appeared to blame Ukraine for Russia’s invasion. "You should have never started it," he said, referring to Ukraine’s leaders.

Here’s what to know about how the war began, the state of the peace talks and Ukraine’s election record.

Recorded during 2024, this year-spanning series of images reveals a pattern in the seasonal drift of the Sun's daily motion through planet Earth's sky. Known to some as an analemma, the figure-eight curve was captured in exposures taken only at 1pm local time on clear days from Kayseri, Turkiye. Of course the Sun's position on the 2024 solstice dates was at the top and bottom of the curve. They correspond to the astronomical beginning of summer and winter in the north. The points along the curve half-way between the solstices, but not the figure-eight curve crossing point, mark the 2024 equinoxes and the start of spring and fall. Regional peaks and dormant volcano Mount Erciyes lie along the southern horizon in the 2024 timelapse skyscape.
