brightness

But people who have been inside recently say the experience is awe-inspiring, the cathedral lifted by a new clarity and brightness that mark a sharp contrast with the pervading gloom of before.

For example, this supernova had a period of brightness that stayed steady for about 20 days before declining, whereas the brightness of its metal-rich counterparts usually lasted for about 100 days.

The aim is to dial up SPring-8’s brightness more than 100 times, making it the world’s most powerful synchrotron.

But some road users say their brightness can be a nuisance.

Vanessa Alarcon, the astrological observer at the Griffith Observatory, said it can be challenging for the human eye to notice these differences in size and brightness, but that shouldn’t stop people from trying.
