Centenary of cosmological constant lambda

more »
Physicists are now celebrating the 100th anniversary of the cosmological constant. On this occasion, two recent articles highlight its role in modern physics and cosmology. Before becoming widely accepted, the cosmological constant had to undergo many discussions about its necessity, its value and its physical essence. Today, there are still unresolved problems in understanding the deep physical nature of the phenomena associated with the cosmological constant.

New observations show the star cluster RCW 38 in all its glory. This image was taken during testing of the HAWK-I camera with the GRAAL adaptive optics system. It shows RCW 38 and its surrounding clouds of brightly glowing gas in exquisite detail, with dark tendrils of dust threading through the bright core of this young gathering of stars.

NASA's Webb Space Telescope to Inspect Atmospheres of Gas Giant Exoplanets

Thousands of exoplanets are known to orbit distant stars. Far fewer have had their atmospheres studied. The Webb telescope will bring new capabilities for determining atmospheric compositions, temperatures, and structures. Some of Webb’s earliest observations will focus on gas giants, whose puffy atmospheres should be easier to inspect. Lessons learned there will apply to later observations of small, rocky worlds.
