The Australian Square Kilometre Array Pathfinder (ASKAP) radio telescope is responsible for finding a number of fast radio bursts. But could there be fainter flashes that it’s missing?

This image shows BOBCAT hardware used to demonstrate the successful transfer of cryogenic fluids into a dewar during a balloon demonstration in August 2019. The shot was taken when the balloon reached its float altitude of 133,000 feet.

This image from NASA's Spitzer Space Telescope shows the Tarantula Nebula in two wavelengths of infrared light. The red regions indicate the presence of particularly hot gas, while the blue regions are interstellar dust that is similar in composition to ash from coal or wood-burning fires on Earth.

Hubble Sees Dusty Galaxy With Supermassive Center

This illustration shows a newly discovered dwarf nova system, in which a white dwarf star is pulling material off a brown dwarf companion. The material collects into an accretion disk until reaching a tipping point, causing it to suddenly increase in brightness. Using archival Kepler data, a team observed a previously unseen, and unexplained, gradual intensification followed by a super-outburst in which the system brightened by a factor of 1,600 over less than a day.
