Newly Discovered ‘Infinity Galaxy’ Could Prove How Ancient Supermassive Black Holes Formed
This collision of two galaxies could demonstrate that theorized “direct collapse black holes” exist.
The Structure of Ice in Space Is Neither Order nor Chaos—It’s Both
Long thought to be completely disordered, space ice appears to have some crystallized regions, new research suggests.
The FDA Just Approved a Long-Lasting Injection to Prevent HIV
Clinical trials have shown that six-monthly injections of lenacapavir are almost 100 percent protective against becoming infected with HIV. But big questions remain over the drug’s affordability.
Astronomers Are Using Artificial Intelligence to Unlock the Secrets of Black Holes

On Earth there is no record of Niallia tiangongensis, a bacterium found aboard the Tiangong station that appears to be well adapted to conditions there.
Scientists Believe They’ve Witnessed ‘Planetary Suicide’ for the First Time
New data from the James Webb Space Telescope suggests a planet in a faraway solar system was consumed by a star by hurling itself into it.
Scientists Think They’ve Found the Region of the Brain That Regulates Conscious Perception
A new experiment suggests that the thalamus plays a key role in humans becoming consciously aware of stimuli their brain receives.
Scientists Find Promising Indication of Extraterrestrial Life—124 Light-Years Away
