    Dark energy Testing
AI Thread Summary
Astrophysicists have created a new method to measure the cosmological constant by analyzing the dynamics of the Local Group. This approach currently provides constraints on dark energy that are five times less effective than existing methods. However, researchers believe that improvements will soon enhance its effectiveness to match current measurements. The study highlights the potential of using local cosmic structures to gain insights into dark energy. This advancement could significantly contribute to our understanding of the universe's expansion.

Unfortunately, it is so far five times less constraining than other measures, but promises to improve to be comparable with existing measures soon.
 

Thread 'Venus and Jupiter Conjunction'

Today at about 4:30 am I saw the conjunction of Venus and Jupiter, where they were about the width of the full moon, or one half degree apart. Did anyone else see it? Edit: The moon is 2,200 miles in diameter and at a distance of 240,000 miles. Thereby it subtends an angle in radians of 2,200/240,000=.01 (approximately). With pi radians being 180 degrees, one radian is 57.3 degrees, so that .01 radians is about .50 degrees (angle subtended by the moon). (.57 to be more exact, but with...

Thread 'Our Beautiful Universe - Photos and Videos'

This thread is dedicated to the beauty and awesomeness of our Universe. If you feel like it, please share video clips and photos (or nice animations) of space and objects in space in this thread. Your posts, clips and photos may by all means include scientific information; that does not make it less beautiful to me (n.b. the posts must of course comply with the PF guidelines, i.e. regarding science, only mainstream science is allowed, fringe/pseudoscience is not allowed). n.b. I start this...
