As NASA’s Artemis II mission completed its lunar flyby, the astronauts sent back a stunning image of the colorful Earth setting behind the moon. This breathtaking photo, called Earthset, draws inevitable comparisons with the original Earthrise photo from the Apollo 8 flight in 1968.

Scientists in Japan have developed a high-resolution X-ray telescope sharp enough to distinguish an object just 3.5 mm wide from one kilometer away, by combining precision mirror-making technology with space astronomy. To test its performance, they built a first-of-its-kind evaluation system, capable of simulating starlight on the ground to measure the telescope’s sharpness before its […]
Japan’s space agency, JAXA, has been knocking it out of the park with small-body exploration missions for decades. They had historic successes with both Hayabusa and Hayabusa2, and they are going to visit the Martian moons soon with the Martian Moons eXploration (MMX) mission. But after that, they are aiming for something much more pristine […]
On August 19, 2022, solar astronomers using the Daniel K. Inouye Solar Telescope (DKIST) on the Hawaiian island of Maui caught the fading remnants of a C-class solar flare. Their observations showed something unusual: very strong spectral fingerprints of calcium II H and hydrogen-epsilon lines.

For decades, astronomers were only able to study the universe’s very first stars using theoretical models. Now, observations from the James Webb Space Telescope (JWST) have revealed what may be the most compelling evidence to date for these ancient “Population III” stars, finding them clustered around a small companion object that formed just 400 million […]
We’ve spent decades scratching the surface of Mars trying to uncover life there. But we’ve been searching a barren wasteland bombarded by radiation and bathed in toxic perchlorates. The entire time, it’s likely that it’s been too hostile to harbor extant life. So if we want a better shot at finding currently living life on […]

By analyzing the data from various space observatories, Chinese astronomers have inspected a nearby quasar designated SDSS J000532.84+200717.4. Results of the new study, published April 1 on the arXiv preprint server, shed more light on the X-ray variability of this object.

Artemis II astronauts expressed awe on Saturday over their record-setting lunar flyby mission, urging unity on Earth after witnessing the planet’s isolation like a “lifeboat” in space.

Astronomers analyzing gravitational-wave data from the LIGO-Virgo-KAGRA Collaboration have reported that merging binary black holes fall into three distinct categories. The study shows that the three subpopulations have their own characteristic masses, spin behavior, and merger rate that may be linked to different dominant formation mechanisms. The paper outlining their results was submitted to the […]
A new study, published in Physical Review Letters, reports that scientists have successfully imaged the formation of cavity-induced density waves induced by laser light in an ultracold quantum gas. Previously, only global signals, such as photon leakage or the peak in energy deposition of a fast charged particle (Bragg peaks), have been used to detect […]

A Majorana fermion is a particle that would be identical to its antiparticle. Such an object has not yet been found. However, certain solid materials exhibit analogous behavior as if Majorana fermions were present through collective excitations of the system called quasiparticles.
