This image of Galveston was taken on Nov. 23, 2022, from the International Space Station as it orbited 224 miles above Earth. While President Abraham Lincoln issued the Emancipation Proclamation in 1863, word that enslaved people were free did not reach Galveston until well into 1865. When Union troops arrived that year to share the […]

Yes, but can your thunderstorm do this? Pictured here are gigantic jets shooting up from a thunderstorm last week toward the Himalayan Mountains in China and Bhutan. The composite image captured four long jets that occurred only minutes apart. Gigantic jets, documented only in this century, are a type of lightning discharge that occurs between […]

Squids on Earth aren’t this big. This mysterious squid-like cosmic cloud spans nearly three full moons on planet Earth’s sky. Discovered in 2011 by French astro-imager Nicolas Outters, the Squid Nebula’s bipolar shape is distinguished here by the telltale blue emission from doubly ionized oxygen atoms. Though apparently surrounded by the reddish hydrogen emission region […]

What happens if a star gets too close to a black hole? The black hole can rip it apart — but how? It’s not the high gravitational attraction itself that’s the problem — it’s the difference in gravitational pull across the star that creates the destruction. In the featured animated video illustrating this disintegration, you […]

This colorized and sharpened image of the Sun is composed of frames recording emission from hydrogen atoms in the solar chromosphere on May 15. Approaching the maximum of solar cycle 25, a multitude of active regions and twisting, snake-like solar filaments are seen to sprawl across the surface of the active Sun. Suspend in the […]

This NASA/ESA Hubble Space Telescope image features the globular cluster NGC 2005. It’s not an unusual globular cluster in and of itself, but it is a peculiarity when compared to its surroundings. NGC 2005 is located about 750 light-years from the heart of the Large Magellanic Cloud (LMC), which is the Milky Way’s largest satellite […]

From the 1960 astronomical catalog of Rodgers, Campbell and Whiteoak, emission region RCW 85 shines in southern night skies between bright stars Alpha and Beta Centauri. About 5,000 light years distant, the hazy interstellar cloud of glowing hydrogen gas and dust is faint. But detailed structures along well-defined rims within RCW 85 are traced in […]

Floating fragments of sea ice spun into intricate patterns as ocean currents carried them south along Greenland’s east coast in spring 2024. The MODIS (Moderate Resolution Imaging Spectroradiometer) on NASA’s Terra satellite captured a moment of this dizzying journey on June 4, 2024. via NASA https://ift.tt/aMdnQ5q

Big, beautiful spiral galaxy Messier 66 lies a mere 35 million light-years away. The gorgeous island universe is about 100 thousand light-years across, similar in size to the Milky Way. This Hubble Space Telescope close-up view spans a region about 30,000 light-years wide around the galactic core. It shows the galaxy’s disk dramatically inclined to […]
