"Even with all of our current technologies, we are still blind to 95 percent of the universe," said Kamal Oudrhiri of NASA's JPL. "Like a new lens in Galileo's first telescope, the ultra-sensitive cold atoms in NASA's Cold Atom Lab have the potential to unlock many mysteries beyond the frontiers of known physics.

The scaffolding that holds the large-scale structure of the universe constitutes galaxies, dark matter and gas (from which stars are forming), organized in complex networks known as the cosmic web. This network comprises dense regions known as galaxy clusters and groups that are woven together through thread-like structures known as filaments. These filaments form the backbone of the cosmic web and host a large fraction of the mass in the universe, as well as sites of star formation activity.

All throughout the universe, there are stars in varying phases and ages. The oldest detected planets found using NASA's Kepler telescope are about 11 billion years old, and the planetary diversity suggests that around other stars, such initially frozen worlds could be the size of Earth and could even provide habitable conditions once the star becomes older. Astronomers usually looked at middle-aged stars like our sun, but to find habitable worlds, one needs to look around stars of all ages.

This past September, China put on the “ear phones” and flipped the “ON” switch for the world’s largest, most powerful radio telescope nestled in a vast, bowl-shaped valley in the mountainous southwestern province of Guizhou. The unrivaled precision of the FAST telescope will allow astronomers to survey the Milky Way and other galaxies and detect faint pulsars, and work as a powerful ground station for future space missions. With a dish the size of 30 football fields, FAST, which measures 500 meters in diameter, dwarfs Puerto Rico’s 300-meter Arecibo Observatory. Under new regulations, FAST requires radio silence within a 10-kilometer radius.
