Explanation: A new comet is brightening and is now expected to become visible to the unaided eye later this month.C/2009 R1 (McNaught) is already showing animpressive tail and is currently visible throughbinoculars.The above image, taken yesterday from theAltamira Observatory in theCanary Islandsand spanning about five degrees, shows an impressivegreen coma and along ion tail in front of distant star trails.Althoughpredicting the brightness of comets is notoriously difficult,current estimates placeComet McNaught asbecoming visible to unaided northern hemisphereobservers in late June, before sunrise, and in early July, after sunset.Discovered byRobert McNaught last year, the sun-orbiting iceberg will pass the Earth next week and will continue to melt and shed debris as itcloses in on the Sun until early July.After reaching about half of theEarth-Sun distancefrom the Sun, the comet should fade rapidly as it then heads out of theinner Solar System.
