Friday: January 14, 2021: A satellite of U.S. Earth-observation company Planet took this video capturing the landed first-stage booster of a SpaceX Falcon 9 rocket that lifted 105 small satellites into low Earth orbit on Jan. 13.

Planet was among the customers on the flight, SpaceX's third dedicated to its new Transporter ride-sharing program. The 44 SuperDove Earth-observing cubesats on board will strengthen the company's 240-strong fleet that can capture an image of every point of Earth multiple times a day.

Thursday, March 16, 2023: A new map reveals water distribution on the moon's surface in best-ever detail.

The map, based on measurements taken by the now retired NASA's air-borne telescope SOFIA, provides hints how water may be moving across the moon's surface, NASA said in a statement.

Friday, March 24, 2023: A surprise solar storm supercharged auroras across the U.S. tonight with colorful displays visible as far south as New Mexico.

The storm, classified as a severe G4 on the 5-grade scale used by the U.S. National Oceanic and Atmospheric Administration (NOAA), even forced the Rocket Lab company to delay a launch of its Electron rocket. Oddly, space weather forecasters didn't see the storm coming as it was caused by a stealthy solar eruption.

Wednesday, March 1, 2023: An American stargazer has caught an unexpected glimpse of aurora during an astrophotography trip to California's Death Valley.

The sighting, documented in this beautiful image that shows the arch of the Milky Way above a purple glowing horizon, may be the southernmost of the aurora spree delivered by a strong solar storm in the last two days of February.

"I was indeed shocked to see this," Shari Hunt, the author of the image, who is a medical researcher and part-time astrophotography tutor, told Space.com in an email. "I was there in Death Valley for night photography and with the storm in California, we had clouds almost every morning blocking the galactic core. This was our last morning to shoot."

Friday, October 7, 2022: An image of Jupiter's ocean-bearing moon Europa taken during a recent flyby by NASA's Juno probe received a psychedelic treatment revealing the mysterious world in unexpected colors.

The picture was taken by Juno's JunoCam camera during the pass on Sept. 29 and was processed by citizen scientist Fernando Garcia Navarro. Navarro's unorthodox treatment lent the rather plain white and brownish moon a psychedelic look, creating a bridge between science and art. โ€“ Tereza Pultarova

Tuesday, February 21, 2023: Japan's cubesat EQUULEUS, which hitched a ride to the moon aboard NASA's Artemis 1 mission in November last year, took a video of Comet C/2022 E3 (ZTF) earlier this month, about two weeks after the ice ball's closest approach to Earth.

The comet โ€” also called the green comet for its hue or the Neanderthal comet, as it hasn't visited Earth since the era of the Neanderthals โ€” can be seen in the video sequence shared on Twitter as a fuzzy white dot traversing a star-studded black-and-white background.

Friday, March 31, 2023: Teams of the New Zealand-based company Rocket Lab successfully recovered the first stage of the Electron rocket after its splashdown in the Pacific Ocean.

Electron lofted two Earth-observation satellites into low Earth orbit on Friday (March 24), but the company only shared the images of the recovery operation on Twitter a week later, Friday, March 31.

The stage has since been transported to Rocket Lab's facilities in New Zealand where it's being inspected and refurbished for future reuse.
