Scientists may have learned the history of the tiny contact-binary moon orbiting asteroid 152830 Dinkinesh, which was the first cosmic stop for  NASA’s Lucy spacecraft. That moonlet may have spun off its larger parent asteroid when Dinkinesh was sent twirling through space after absorbing and re-emitting sunlight. Having launched in 2021, the Lucy mission is

Using the Euclid space telescope, scientists have discovered a staggering 1.5 trillion orphan stars drifting through a massive cluster of thousands of galaxies, one of the largest structures in the cosmos. These orphan stars, ripped free from their own galaxies, are filling the space between the galaxies of the Perseus cluster with ghostly blue light.

Two Chinese astronauts just set a new spacewalking record for the country. Ye Guangfu and Li Guangsu, two members of China’s three-person Shenzhou 18 mission, spent about 8.5 hours working outside the Tiangong space station today (May 28). That’s longer than any previous Chinese spacewalk, or extravehicular activity (EVA), according to the nation’s state-run Xinhua

Earth orbit is becoming increasingly polluted. NASA estimates that at least 500,000 pieces of debris 1 cm or greater circle our planet; ESA estimates more than 1 million. As the number of spacecraft we launch into orbit or beyond grows, so too does the amount of debris we leave in their wake. Uncontrolled debris is

The four zebrafish China sent to its space station are thriving after spending almost a month in orbit.
