New planet is also blue

Weekend Argus (Saturday Edition) - - NEWS -

LON­DON: As­tronomers have for the first time de­ter­mined the colour of a planet out­side the so­lar sys­tem, a blue gas gi­ant some 63 light years away.

An in­ter­na­tional team of as­tronomers work­ing with the Hub­ble Tele­scope made the dis­cov­ery ob­serv­ing the planet HD 189733B.

To as­cer­tain the planet’s colour, as­tronomers mea­sured the light re­flected off its sur­face as it eclipsed its host star.

The planet be­longs to a group of “hot Jupiters” and has a tem­per­a­ture of about 1 000°C. – Sapa-AP
