Webb Reveals New Structures Within Iconic Supernova
NASA’s James Webb Space Telescope has begun the study of one of the most renowned supernovae, SN 1987A (Supernova 1987A). Located 168,000 light-years away in the Large Magellanic Cloud, SN…
Across the Northern Hemisphere, now’s the time to catch a new comet before it vanishes for 400 years
This image provided by Gianluca Masi shows the comet C/2023 P1 Nishimura and its tail seen from Manciano, Italy on Sept. 5, 2023. Stargazers across the Northern Hemisphere should catch…
Removal of Caltech Submillimeter Observatory Telescope from Maunakea Underway
Disassembly of the Caltech Submillimeter Observatory’s 34-foot diameter telescope on Maunakea has begun. The current plan is to disassemble the telescope and its mirror into smaller parts and transport them…
Vast bubble of galaxies discovered, given Hawaiian name
The red region (left) shows the shell enclosed by the Baryon Acoustic Oscillation, with individual galaxies depicted as luminous tiny specks. The blue filaments show the greater Cosmic Web, with…
It’s going to take more than early dark energy to resolve the Hubble tension
Hubble tension has gotten worse lately. Credit: Perivolaropoulos and Skara Our best understanding of the universe is rooted in a cosmological model known as LCDM. The CDM stands for cold…
