Sick day.

Artist rendering of brown dwarf. This particular brown dwarf was discovered in 2008 and is the coolest brown dwarf yet, with a surface temperature of 623 Kelvin (that’s only 350 Celsius or 660 degrees Fahrenheit). Compare with the surface temperature of our Sun, a modest 6,000 Kelvin. This is one cool dwarf. #science #space #browndwarf #star #AstrosWord
