The Hubble telescope of NASA has discovered massive dead galaxies. These are the ones that had run out of cold hydrogen gas, the same which is needed to make stars.

Scientists, earlier this year, were studying the early galaxies.

And they were surprised to discover these six massive galaxies that seem to have died.

Hubble telescope spied on these six galaxies . It observed that they ran out of cold hydrogen gas while most of the other galaxies were producing new stars at a faster speed.

According to NASA, when the universe was about 3 billion years old, it experienced the most prolific period of star birth in its history.

Also, the Hubble Space Telescope and the Atacama Large Millimeter/submillimeter Array in Northern Chile looked towards the cosmic objects.

They found six early, massive, empty galaxies. These galaxies were without fuel for star formation, were running on empty.

Without the cold hydrogen gas, the galaxies were essentially dead. NASA’s Hubble telescope was used to pinpoint the galaxies.

And with the use of the Atacama Large Millimeter/submillimeter Array (ALMA) in Chile, the researchers were able to find out whether the galaxies were containing the cold dust or not.

But since the galaxies are so old and so far away, the dead galaxies would not have been spotted with the technique known as ‘gravitational lensing.’

The astronomers’ team used super-massive galaxy clusters closer to our earth as natural telescopes.
