Could this asteroid be a piece of the moon? A Chinese spacecraft is about to find out
The moon is not the only natural object traveling through space alongside Earth. Several small asteroids travel around the sun in near lockstep with our planet. And just like Earth, these space rocks also take a year to complete a full orbit. Today, we know of eight such "quasi-m
NASA's Hubble spots star-spangled cosmic scene
More than 500,000 stars blaze red, white, and blue in this image from NASA's Hubble Space Telescope, released in celebration of the United States' 250th anniversary. The image showcases Messier 3 (M3), one of the Milky Way galaxy's most massive globular clusters, or spherical col
JWST discovers a new barred spiral galaxy
An international team of astronomers reports the discovery of a new massive barred spiral galaxy. The newfound galaxy, designated M1149-BSG-z5, was identified using the James Webb Space Telescope (JWST). The finding was detailed in a paper published June 23 on the preprint server
Ultrafast scanning tunneling microscopy reaches the quantum mechanical space-time limit fo
Werner Heisenberg's famous uncertainty principle describes one of the most intriguing features of quantum physics: certain pairs of physical quantities describing a particle, such as position and momentum, cannot simultaneously be determined with arbitrary precision—not because o
NASA celebrates America's 250th birthday with incredible views of space
NASA is marking the United States' 250th birthday with four striking red, white, and blue images of deep space from the Chandra X-ray Observatory. The collection features an exploded star, a stellar nursery, a galaxy where stars are rapidly forming, and a galaxy cluster that prov
NASA's Hubble spots a stellar sparkler for the Fourth of July
NASA's Hubble Space Telescope has captured a spectacular red, white, and blue view of one of the Milky Way's oldest star clusters to celebrate the nation's 250th anniversary. Hidden within the ancient cluster are clues to how exploding stars helped transform the young universe in
Why put solar panels on green space when we could put them over car parks?
The long-running series in which readers answer other readers’ questions considers a hot topic within renewable energyThis week’s replies: Are there places on Earth where humans haven’t been?I would like to know why we build solar farms over green space, when we could just put th
Japan space probe skims asteroid in test for planetary defense
A Japanese space probe performed a flyby of a near-Earth asteroid on Sunday in a test mission for technology that could help protect the planet from space rocks.
China's space probe reaches asteroid after 1-billion-kilometer chase for first sample retu
China's Tianwen-2 space probe, which is set to bring back samples from an asteroid for research, has reached its target after traveling 1 billion kilometers (620 million miles) over more than a year, the Chinese space agency said Monday.
Euclid discovers the most ancient quasars in the universe
The European Space Agency's Euclid space telescope has discovered 31 of the most ancient quasars ever found. Two of these giant and dazzling galaxy cores, powered by gargantuan black holes, are the earliest quasars yet observed in cosmic history. They shone with the light of a tr
