We all are very much fascinated about the universe and cosmos, the beauty of it always leaves us awestruck. What attracts us when we see towards the sky at night? Of course, it is the brightness of the stars. More it glitters, we like it more. This simple phenomenon compels scientists to explore the very reason for their brightness.
More precisely scientists find it interesting to find out significant factors to contribute to the effect of brightness, which is purely on reflectance value of light termed as albedo effect in the study of light. It is understood that Venus, the bright star has 70%, earth 50%, and many stars 10% reflectance or even less. Size or surface area of planet or distance their of, may not be significant for this albedo. Some of the planets may take more than

Lava planets are like balls revolving in the space and the temperature may be as high as 850 degrees Kelvin in a molten state. Just to have a replica of planet masses, the team took two minerals namely feldspar and basalt, but these get cooled in a shorter time and leave little time to measure reflectivity. The value was measured at different angles by taking in purely volcanic glasses.
The outcome for even upper limits was just 10% of the host star’s light as opposed to 70% in the case of the brightest star in the galaxy. This is little unexplained and leaves much scope for further studies of atmospherically other factors like positioning with host stars and density of air among different layers of air around the planet.
