Astronomers have discovered a galaxy cluster in the distant universe that is more mature than expected, with unprecedented mass concentration toward its center. The James Webb Space Telescope images reveal strong gravitational lensing effects, providing valuable insights into dark matter distribution and cosmological models.
Astronomers at Caltech IPAC have settled on a leading hypothesis for the unusual hot spot on CoRoT-2 b, a hot Jupiter that defies previous assumptions about its behavior. The planet's slow rotation speed, which is equivalent to about three Earth days per orbit, suggests it is not tidally locked to its host star.
Researchers find shared dusty layer of troilite on M- and K-type asteroids, suggesting they originated from similar large objects. Polarization studies reveal unique composition linking these distinct asteroid types.
Tom Greene joins Caltech IPAC as Executive Director, leveraging his scientific management skills and research background in exoplanet studies and galaxy evolution. He succeeds George Helou, who steps down after 25 years as Executive Director.
The final data release from NASA's NEOWISE mission encompasses over 26 million images and nearly 200 billion sources detected by the telescope. The new images showcase the full-sky coverage of the survey, revealing previously unseen regions of cosmic dust where stars are born.
