A research team from the Academia Sinica recently achieved a breakthrough in astronomy by observing never-before-seen submillimeter galaxies, of which the number greatly exceeds previous estimation. The new discovery is expected to help advance humanity's knowledge and under

This image was recently captured by NASA's Hubble Space Telescope. Submillimeter galaxies were extremely common in the years after the Big Bang.

Although they are thousands of times brighter than the Milky Way, most of their visible light is absorbed by dust and their thermal radiation can only be observed using far infrared telescopes or the Submillimeter Array.

Using the SMA, Academia Sinica researchers recently gained a clear view of submillimeter galaxies. Generally speaking, only the brightest of the thousands of submillimeter galaxies that exist in the universe are visible.

Using high-performance telescopes, the Academia Sinica team discovered twice the number of previously known submillimeter galaxies in two sections of the sky.

The universe is 14 billion years old,

and submillimeter galaxies formed 2 billion to 6 billion years after the Big Bang.

The Academia Sinica hopes that the world's largest astronomical project, the Atacama Large Millimeter/submillimeter Array, will shed more light on the mysteries of the universe when it is completed in three years.
