The largest radio telescope in the world officially opened on Sunday, according to China’s official Xinhua News.

The Five-hundred-meter Aperture Spherical Telescope, or FAST, is named after its diameter, which at 500 meters makes it 195 meters wider than the second largest telescope of its kind, the Arecibo Observatory in Puerto Rico.

Xinhua reports the telescope cost $180 million, and displaced 8,000 people from their homes to create the necessary 3-mile radius of radio silence around the facility. It will be used for “observation of pulsars as well as exploration of interstellar molecules and interstellar communication signals.”

These amazing images capture the moon during a total solar eclipse revealing a vast solar corona. Clarity was achieved due to the incredibly remote location chosen to view the eclipse from, a pier just outside the Enewetak Radiological Observatory on the Marshall Islands, smack dab in the middle of the Pacific Ocean.  All images are courtesy of the photographer.

NASA’s Hubble Spots Possible Water Plumes Erupting on Jupiter's Moon Europa

Astronomers using NASA’s Hubble Space Telescope have imaged what may be water vapor plumes erupting off the surface of Jupiter’s moon Europa. This finding bolsters other Hubble observations suggesting the icy moon erupts with high altitude water vapor plumes.

The observation increases the possibility that missions to Europa may be able to sample Europa’s ocean without having to drill through miles of ice.

“Europa’s ocean is considered to be one of the most promising places that could potentially harbor life in the solar system,” said Geoff Yoder, acting associate administrator for NASA’s Science Mission Directorate in Washington. “These plumes, if they do indeed exist, may provide another way to sample Europa’s subsurface.”
