What lies between the stars?
Astronomers simulated the clouds of material between stars. They found that regions of space with more heavy elements tend to be cooler and…
These gases could signify intelligent life beyond Earth
Astronomers proposed that the industrial gases nitrogen trifluoride and sulfur hexafluoride could provide measurable signs of advanced…
JWST reveals properties of dusty star-forming galaxies
Astronomers used new JWST data to unravel the structures of 22 dusty star-forming galaxies that previous telescopes couldn’t see.
Astronomers model early star clusters
Scientists used computer simulations to determine how ancient star clusters formed. Their results were similar to real clusters found with…
Scientists observe a changing exoplanet orbit
Astronomers conducted a multifaceted study of the exoplanet TrES-1 b and found that its orbit is shifting, possibly due to an unseen…
How did early galaxies form?
Astronomers observed a distant, ancient galaxy and found that it consisted of 5 distinct regions, suggesting a complex formation history…
How often are stars flung out of the center of the Galaxy?
Researchers surveyed stars in the Milky Way Galaxy and found they’re only rarely ejected from the Galaxy's center.
