When the universe was around 500 million years old, this unusual black hole had already accumulated enormous mass. By analyzing its evolution, astronomers were able…
Astronomers have found “hidden” quasars
Quasars have different characteristics that represent different stages in the origin of these bright objects. Also, despite their brightness, many of them managed to “hide”…
An unusual phenomenon has been discovered in black holes: they eat food in a different way than expected
Astronomers have discovered that supermassive black holes have a special mechanism that prevents them from growing. The black hole at the center of the galaxy…
Gas giant planets revealed as ‘agents of chaos’
Gas giants can prevent the emergence of life on neighboring planets, being “agents of chaos”. This is the conclusion reached by scientists from the University…
A failed replica of the solar system found in data from the Kepler space telescope
The Kepler space telescope stopped collecting data in 2018, but remains a source of discoveries. To date, Kepler’s data contain the largest collection of exoplanets…
Scientists are wary of the behavior of the black hole at the center of the Milky Way
An object roughly the size of the solar system not only contains hundreds of billions of stars around it, but also twists the invisible “fabric”…
The active core of the Circulus galaxy has dispersed almost all the gas that fell into it Only a small portion of the gas will be absorbed by the black hole
The ground-based ALMA radio telescope has helped astronomers determine that only a tiny fraction of the gas flowing toward the supermassive black hole at the…
Astronomers have discovered a rare system of seven planets
Over the past decades, ground-based and orbiting observatories have discovered thousands of exoplanets of various sizes. Some of them look like Earth, others look like…

Scientists think Betelgeuse swallowed its companion star
Betelgeuse has been the subject of scientific interest in recent years because its brightness has changed dramatically several times. Earlier this year, the red superstar…
