But the Herschel infrared space telescope – which has the ability to peer into these dense clouds — has made an unexpectedWhat do you want from the future?
discovery. This

black patch is actually a hole it's your turnthat has been blown in the side of the nebula by the jets and winds of gas from the young stellar objects in this

region of space.“No-one has everout of your control seen a hole like this,” said Tom Megeath, of the University of Toledo in the USA. “It’s as surprising as knowing

you have worms tunneling under your lawn, but finding one morning that they have created a huge, yawning pit.”
Any previous descriptions of NCG 1999 said that the ominous dark cloud in the center was actually a condensation of cold molecular gas and dust

so thick and dense that it blocks light.Make youself a better person And astronomers had no reason to believe otherwise, until Herschel's powerful infrared eyes took a look

from space.IN PICTURES: Spectacular supernovasWhen Herschel looked in the direction of this nebula to study nearby young stars, the cloud

continued to look black. But, that should not be the case. Herschel’s infrared eyes are designed to see into such clouds. Either the cloud was

immensely dense or something was wrong.Investigating further using ground-based telescopes, astronomers found the same story however

they looked: this patch looks blackthe gateway to a world not because it is a dense pocket of gas but because it is truly empty. Something has blown a hole right

through the cloud.Stars are born in dense clouds of dust and gas. Although jets and winds of gas have been seen coming from young stars in

the past, it has always been a mystery exactly how a star uses these to blow away its surroundings and emerge from its birth cloud. With

Herschel, this may be the first time we can see this process.The astronomers think that the hole must have been opened when the narrow jets

of gas from some of the young stars in the region punctured the sheet of dust and gas that forms NGC 1999. The powerful radiation from a

nearby mature star may also have helped to clear the hole. Whatever the precise chain of events, it could be an important glimpse into the way

newborn stars disperse their birth clouds.ource: ESAIN PICTURES: Spectacular photos of Supernovae and their remnantsNancy Atkinson blogs at
