The Euclid team has released a beautiful new image of NGC 6397, one of the closest globular clusters to Earth. NGC 6397, or GCl 74, is located 7,800 light-years...
Astronomers from Trinity College Dublin, the Breakthrough Listen project and Onsala Space Observatory have demonstrated the effectiveness of using multisite...
A stable-frequency transmitter with relative radial acceleration to a receiver will show a change in received frequency over time, known as a ‘drift...
The outer disk of our Milky Way Galaxy is warped and flared. Several mechanisms have been proposed to explain these phenomena, but none have reproduced...
Astronomers using the NASA/ESA Hubble Space Telescope have captured a stunning image of the globular cluster Terzan 12, a vast, tightly bound collection...
The detection of the cosmogenic isotope aluminum-26; the concentrations of nickel, cobalt, germanium and gallium; and the presence of two minerals called...
The Search for Extraterrestrial Intelligence (SETI) aims to answer one of the most important scientific questions: are we alone in the Universe? Complementing...
Observations of high-energy astrophysical neutrinos have shown that they mostly originate from extragalactic sources such as active galaxies. However,...
The center of the Milky Way Galaxy hosts Sagittarius A*, a supermassive black hole with a mass of about 4 million solar masses that is very quiescent....
Early Universe’s stars had up to several hundred solar masses. The earliest stars of 140-260 solar masses became pair-instability supernovae (PISNe)....
The Breakthrough Listen Investigation for Periodic Spectral Signals (BLIPSS) is a novel software architecture utilizing a fast folding algorithm to enable...
Glacial cycles during the Early Pleistocene epoch are characterized by a dominant 41,000-year periodicity and amplitudes smaller than those of glacial...
Mobile communication towers represent a relatively new but growing contributor to the total radio-leakage associated with planet Earth. In new research,...
Intermediate-mass black holes in the mass range between 100 and 100,000 solar masses are the missing link between stellar-mass black holes and super massive...
The aftermaths of supernovae always produce X-rays, but if the supernova’s blast wave strikes dense surrounding gas, it can produce a particularly large...
The newly-discovered dormant black hole, named Gaia BH2, is orbited by a red giant star, and has a mass of 8.9 solar masses.
The location of Gaia BH2 and...
To facilitate studies of exo-Venus candidates, astronomers from the University of California, Riverside, the University of California, Santa Cruz, Brown...
In unveiling the nature of the first stars, the main astronomical clue is the elemental compositions of the second generation of stars, observed as extremely...
The new animation shows the gamma-ray sky’s frenzied activity during a year of observations by the Large Area Telescope (LAT) aboard NASA’s Fermi Gamma-ray...
