A strange world covered with metallic clouds has been spotted in the cosmos. It is called LTT9779 b and is an extremely reflective exoplanet<\/a>.<\/p>\n\n\n

The exoplanet is about the size of Neptune, making it the largest “mirror” of the Universe<\/strong> that we know of today,” writes the European Space Agency, whose Cheops exoplanet satellite made the observation.<\/p>\n\n\n\n

Cheops, short for “CHaracterising ExOPlanet Satellite,” is a mission aimed at closely studying other solar systems<\/strong> and better categorizing the mysterious planets they harbor. India is going for the Moon, by the way<\/a>.<\/p>\n\n\n\n

A mirror planet, never seen before<\/h2>\n\n\n\n

Cheops uses a single high-tech telescope to observe exoplanets in deep space while waiting for these distant spheres to transit in front of their respective stars.<\/p>\n\n\n\n

This temporarily dims the star, allowing astronomers to analyze the tiny changes in light that ultimately determine the size, density, and other characteristics of these exoplanets.<\/p>\n\n\n\n

By observing LTT9779 b, located about 262 light-years away<\/strong>, Cheops was able to see the strong combination of light coming from both the planet and its star, as opposed to light coming only from the star (when LTT9779 b was transiting behind it).<\/p>\n\n\n\n

The Earth reflects about 30% of sunlight. But LTT9779 b reflects 80% of the light from its star<\/strong>.<\/p>\n\n\n\n
