A research team led by Prof. LI Di from the National Astronomical Observatories of the Chinese Academy of Sciences (NAOC) has revealed circular polarization in active repeating fast radio bursts based on precise observations of the Five-hundred-meter Aperture Spherical Telescope (FAST). Fast radio bursts (FRBs) are the most luminous radio flashes in the universe. The estimated equivalent e

A team of scientists including physicist Johanna Nagy at Washington University in St. Louis successfully launched a balloon-borne experiment studying the early universe on Dec. 21. The instrument, called SPIDER, was carried aloft by a scientific balloon from its launch pad in Antarctica. Nagy, an assistant professor of physics in Arts and Sciences, is one of a team of scientists who will u

China's private company GalaxySpace is accelerating the research and development of flat-panel stackable satellites, for rapid construction of a satellite internet constellation. GalaxySpace said the design enables dozens of satellites to be stacked on top of each other like tablet personal computers and be launched at the same time on a single rocket. It can greatly improve the use effici

A Falcon 9 rocket carrying 54 Starlink Internet satellites launched from Florida on Wednesday as part of a mission to begin populating a new orbital shell authorized by federal regulators. The rocket launched from Cape Canaveral Space Force Station at 4:34 a.m. The mission was SpaceX's 60th of the year, nearly double the total from last year. One more launch is scheduled for the end of

he non-exclusive SpaceX study regarding the possibilities of reboosting the Hubble Space Telescope is ongoing. On Thursday, Dec. 22, 2022, NASA issued a Request for Information to seek additional information about commercial capabilities available to reboost a satellite in orbit, using Hubble as a demonstration, at no cost to the government. There are no plans at this time for NASA to cond

Researchers have uncovered a previously hidden heating process that helps explain how the atmosphere that surrounds the Sun called the "solar corona" can be vastly hotter than the solar surface that emits it. The discovery at the U.S. Department of Energy's (DOE) Princeton Plasma Physics Laboratory (PPPL) could improve tackling a range of astrophysical puzzles such as star formation, the o

Researchers are preparing for a potentially "catastrophic" close encounter with an asteroid in 2029 by scanning an asteroid with radio waves on Tuesday. NASA is teaming with scientists from the University of Alaska Fairbanks' Geophysical Institute to send about 9.6 million radio waves to 2010 XC15, an asteroid that will pass by about twice the distance from Earth to the Moon. The

NASA and the Russian space agency Roscosmos are evaluating if they will need to mount a rescue mission to the International Space Station after discovering a coolant leak from the Russian Soyuz spacecraft currently docked at the station. The leaking spacecraft, designated Soyuz MS-22, carried U.S. astronaut Frank Rubio, along with cosmonauts Dmitri Petelin and Sergey Prokopyev to the In
