Using the Murchison Widefield Array (MWA) telescope at CSIRO’s Murchison Radio-Astronomy Observatory, astronomers are searching for the elusive Epoch...
As part of the Widefield ASKAP L-band Legacy All-sky Survey (WALLABY), an international team of astronomers has observed the dwarf galaxy pair NGC 4532...
A supermassive black hole in the center of the radio quasar RACS J032021.44-352104.1 (RACS J0320-35 for short) is growing at one of the fastest rates ever...
Using data collected by sensors on the U.S. Department of Defense Space Test Program Satellite 6 (STP-Sat6) in geostationary orbit, scientists have found...
In a new study, a team of astronomers from Penn State and NASA’s Jet Propulsion Laboratory analyzed when and where human deep space transmissions would...
In a new study, a team of researchers from the University of Manchester performed comprehensive simulations of Earth’s radar systems as potential technosignatures...
The unusual radio pulses were detected by the Antarctic Impulsive Transient Antenna (ANITA) experiment, a range of instruments flown on NASA balloons high...
Astronomers have discovered the largest known cloud of energetic particles surrounding a galaxy cluster — the 20-million-light-year-wide cloud around...
2MASX J23453268-0449256 (J2345-0449 for short), an extremely massive, rapidly rotating, jet-launching spiral galaxy approximately 947 million light-years...
Astrophysicists have found that a recently-discovered transient radio source, ILT J110160.52+552119.62, whose roughly minute-long pulses arrive with a...
The field of SETI searches for technosignatures could provide the first detection of life beyond Earth through the technology that an extraterrestrial...
