Orbital science, astronomy, remote sensing, and what lies beyond the atmosphere.
ESA/Hubble has released a new Hubble image of NGC 6723, a glittering globular cluster in Sagittarius that sits about 27,000 light-years from Earth. The scene looks delicate, but it belongs to one of the oldest classes of objects in the Milky Way. Inside its crowded glow, astronomers see evidence that this stellar “chandelier” formed through…

A study in Science Bulletin reports that China’s Einstein Probe detected an extraordinary X-ray outburst called EP250702a, a fast and brilliant event that may reveal an intermediate-mass black hole tearing apart a white dwarf star. If the interpretation holds, the observation would give astronomers a rare view of a predicted but elusive kind of black…
NASA is now examining the thousands of images and spoken observations gathered during Artemis II, after the crew used months of geology training to study the Moon during their April 6, 2026, flyby. The mission gave Reid Wiseman, Victor Glover, Christina Koch and Jeremy Hansen a rare assignment. They had to look at the lunar…
Researchers led by Northwestern University used Keck Observatory observations to uncover a striking pattern in the spins of distant worlds. Their study, published in The Astronomical Journal, found that giant gas planets tend to rotate faster than more massive brown dwarf companions after accounting for mass, size and age. The finding gives astronomers a new…
