NASA has brought the humans on earth even closer to the universe. With its high quality images, knowledge base sharing and making the best possible use of social media to show what’s out there, NASA never fails to give us ample reasons to praise the mother nature.
This time the space agency’s latest share is about a nebula.
There is a hand-shaped structure. As the netizens can see it too, in gold in these pictures. But that is a nebula of energy and particles blown by a pulsar left behind after a star exploded.
The post as obvious has gathered thousands of likes and comments. A nebula is a large cloud of dust and gas in space. Some nebulae also come from the gas and dust thrown out by the explosion of a dying star. Supernova is an example of it. Other nebulae are regions where new stars are beginning to form.
The gases are mostly hydrogen and helium. The dust and gases in a nebula are very spread out. It is the gravity that slowly begins to pull together clumps of dust and gas. As these clumps get bigger and bigger, their gravity gets stronger and stronger.
