New Views of Planet Earth | NASA's PACE Earth Ocean & Atmosphere Satellite
PACE's data is helping us better understand how the ocean and atmosphere exchange carbon dioxide. In addition, it is revealing how aerosols might fuel phytoplankton growth in the surface ocean. Novel uses of PACE data will benefit our economy and society. For example, it will help identify the extent and duration of harmful algal blooms. PACE is extending and expanding NASA's long-term observations of our living planet.

Green and Blue Flashes at Sunset over Norway | Earth Science
Green and Blue Flashes at Sunset over Norway | Earth Science
Astrophotographer Ronny Tertnes: "Tonight's sunset gave us good Greenslashes that were also Blue . . . I haven't seen that very often . . . "
Blue flashes are formed in the same way as green flashes. A mirage magnifies tiny differences in the atmospheric refraction of red, green and blue light. Blue flashes are harder to see than green flashes because blue flashes blend into the surrounding blue sky. When the air is exceptionally clear, however, the blue flash emerges.
This trick of light occurs at sunset and sunrise when light from the Sun travels through the thickest part of Earth’s atmosphere. Acting like a prism, Earth's atmosphere bends, or refracts, the light and separates it into its component wavelengths. Blue and violet light are usually scattered by the atmosphere, while red, orange, and yellow are refracted below the solar disk below the horizon, leaving the green light the most visible during the few seconds that the Sun disappears below the horizon.
Atmospheric layers create altitude-variable refractions that take light from the top of the Sun, dispersing its colors, creating multiple images, and magnifying it in just the right way to make thin slivers appear green (and blue), just before it disappears.

Russia Test Launches New Medium-Class Soyuz-5 Rocket at Baikonur Cosmodrome
Russia Test Launches New Medium-Class Soyuz-5 Rocket at Baikonur Cosmodrome
A new Russian medium-class launch vehicle Soyuz-5 was launched for the first time from the Baikonur Cosmodrome in Kazakhstan at 2 pm EDT (18:00 UTC) on Thursday, April 30, 2026, as part of its first flight tests, Russia’s state space corporation Roscosmos said.
The Soyuz-5 flight went well on its suborbital test. “The first and second stages of Soyuz 5 performed as planned, and a mockup was launched onto the calculated suborbital trajectory, followed by a reentry into an area in the Pacific Ocean previously closed to shipping and aviation,” according to Roscosmos.
The Soyuz-5 is a replacement for the medium-class Zenit rocket using domestic components for its fuel tanks. The Soyuz-5 uses the same basic type of Russia-built RD-171 engine that flew on its Zenit rocket. Soyuz-5’s performance slots it in-between Russia’s smaller legacy Soyuz-2 rocket and the heavy-lift Angara-A5.

Arianespace Ariane 6 Rocket Launch of Amazon Leo LE-02 Internet Satellites
Arianespace Ariane 6 Rocket Launch of Amazon Leo LE-02 Internet Satellites
Designated VA268 by Arianespace and LE-02 by Amazon Leo, this mission was the second of 18 Ariane 6 launches planned for the deployment of the Amazon Leo constellation.
With this launch, Ariane 6, Europe's heavy-lift launcher, confirms its full operational capability. Equipped with four solid-propellant boosters, the launcher deployed 32 satellites in a complex sequence involving 12 separation phases, demonstrating its ability to meet the requirements of large-scale constellation missions. The satellites were accommodated under a 20-meter-long fairing, bringing the launcher's total height to approximately 62 meters.
This flight marks Ariane 6's seventh launch, and the second in its Ariane 64 configuration.
Mission VA268 is part of a series of 18 launches contracted to Arianespace for the deployment of the Amazon Leo constellation. Amazon Leo is Amazon's low Earth orbit satellite network, designed to deliver fast, reliable internet to communities currently beyond the reach of existing networks.
360th launch by Arianespace, 2nd Arianespace launch in 2026
32 Amazon Leo satellites deployed by mission VA268, 64 satellites deployed by Ariane 6 since the beginning of the campaign

Planetarium View: Galaxy AM 0644-741 in Volans—The Lure of The Rings | Hubble
Planetarium View: Galaxy AM 0644-741 in Volans—The Lure of The Rings | Hubble
The sparkling blue ring is 150,000 light-years in diameter, making it larger than our entire home galaxy, the Milky Way. The galaxy, cataloged as AM 0644-741, is a member of the class of so- called "ring galaxies." It lies 300 million light-years away in the direction of the southern constellation Volans.
Ring galaxies arise from a collision where one galaxy plunges directly through the disk of another one. The prominent ring of galaxy AM 0644-741 is the result of a hit-and-run event by a celestial neighbor. The spiral galaxy visible to the left of AM 0644-741 is not the culprit, as it is actually a background galaxy that is not interacting with the ring galaxy at all.
The gravitational shock imparted by a collision of this kind drastically changes the orbits of stars and gas in the "target" galaxy's disk, causing them to rush outward. As the ring plows outward into its surroundings, gas clouds collide and are compressed. The clouds can then contract under their own gravity, collapse, and form an abundance of new stars.
The rampant star formation explains why the ring here is so blue: It is continuously forming massive, young, hot stars that are blue in color. Associated with them are the pink regions visible along the ring. These are rarefied clouds of glowing hydrogen gas, fluorescing because of the strong ultraviolet light from the newly formed massive stars.

How Do Stars Influence the Search for Life? | We Asked a NASA Expert
When astronomers search for life on other worlds, they look for atmospheric molecules called biosignatures, or gases that could indicate biological activity. However, starlight can greatly alter a planet’s atmosphere through photochemistry, sometimes creating or destroying these signals.
A NASA scientist explains why understanding a planet’s star is essential when searching for life beyond our solar system.

NASA Artemis II Moon Crew Visits The United Nations: ‘Ambassadors of the Cosmos’
Back from their mission to the Moon, astronauts from NASA's Artemis II crew arrived at United Nations Headquarters in New York City on April 30, 2026, with a message for humanity about our shared purpose on Earth.
The first crewed test flight of NASA’s Artemis program lifted off from Launch Pad 39B at the agency’s Kennedy Space Center in Florida on April 1, 2026, carrying the first astronauts to travel to the Moon in more than half a century.
During their nearly 10-day mission, the crew completed a record-setting lunar flyby, taking them 252,756 miles at their farthest distance from Earth and 4,067 miles above the lunar surface at their closest approach.
Artemis II splashed down on April 10 in the Pacific Ocean off the coast of San Diego. Following splashdown and recovery, the four crew members underwent post-mission medical evaluations before returning to shore and boarding an aircraft bound for Houston.

What's Up for May 2026: Skywatching Tips from NASA | Jet Propulsion Laboratory
Here are examples of skywatching highlights for the northern hemisphere in May 2026:
The Eta Aquarid meteor shower brings shooting stars before dawn, the Moon meets brilliant Venus after sunset, and May wraps up with a rare Blue Moon. Look to the early morning sky around May 5-6, 2026, for meteors from Halley’s Comet, although bright moonlight may wash out some of the fainter streaks.
Then on May 18, spot the crescent Moon near Venus low in the western sky just after sunset. May ends with a Full Moon on May 31.
May ends with a Blue Moon, meaning the second full moon in a single calendar month, but it will not actually look blue.

Expedition 74 flight engineer and NASA astronaut Chris Williams: "On April 27th at about 10:40 PM GMT, I was in the International Space Station's Cupola and saw something really neat. I was scanning the sky to try to catch a glimpse of the approaching Progress MS-34 vehicle bringing new supplies. Just as we were passing over West Africa, I saw a bright object directly below us, streaking through the upper atmosphere. I saw its tail grow and then split apart into a shower of smaller pieces. I think it must have been some piece of orbital debris or a satellite breaking up as it entered the atmosphere. It was quite a light show!"
