At the center of our Milky Way lies a supermassive black hole (SMBH) called Sagittarius A* (SgrA*). Supermassive black holes reside at the centers of most galaxies, and when they actively accrete gas and dust onto their surrounding hot...
Research shows that a new telescope could detect a potential signature of life on other planets in as little as 60 hours.
"What really surprised me about the results is that we may realistically find signs of life on other...
In recent years there has been an exhaustive study of red dwarf stars to find exoplanets in orbit around them. These stars have effective surface temperatures between 2400 and 3700 K (over 2000 degrees cooler than the Sun), and...
In the recent past, space missions dedicated to the study of astrophysical signals in the high-energy spectrum revealed a series of enigmatic excesses not predicted by the theoretical models. In order to find an explanation for these anomalies, many...
The probe flew closer to Jupiter's largest moon, Ganymede, than any other spacecraft in more than two decades, offering dramatic glimpses of both the icy orb and the gas giant.
On June 7, 2021, NASA's Juno spacecraft flew closer to...
A survey of star formation activity in the Orion Nebula Cluster found similar mass distributions for newborn stars and dense gas cores, which may evolve into stars. Counterintuitively, this means that the amount of gas a core accretes as...
In the search for life on other planets, the presence of oxygen in a planet's atmosphere is one potential sign of biological activity that might be detected by future telescopes. A new study, however, describes several scenarios in which...
NASA's Hubble Space Telescope is "seeing double." Peering back 10 billion years into the universe's past, Hubble astronomers found a pair of quasars that are so close to each other they look like a single object in ground-based telescopic...
An analysis by Dark Energy Survey physicists yields more precise estimates of the average density of matter as well as its propensity to clump together -- two key parameters that help physicists probe the nature of dark matter and...
