U.S. astrophysicists has found via simulations that some black holes might be traveling through space at nearly one-tenth the speed of light.
Megastorms occur approximately every 20 to 30 years on Saturn and are similar to hurricanes on Earth, although significantly larger. But unlike Earth’s hurricanes, no one knows what causes megastorms in Saturn’s atmosphere.
For the first time in nearly three decades of observations, clouds seen on Neptune have all but vanished. The observations reveal a connection between Neptune's disappearing clouds and the solar cycle.
An international team of astronomers have identified a powerful magnetic field in the Wolf-Rayet star HD 45166, the exposed helium core of a star that has lost its outer layers of hydrogen.
NASA's James Webb Space Telescope has followed up on observations by the Hubble Space Telescope of the farthest star ever detected in the very distant universe, within the first billion years after the big bang.
TOI-4860b happens to orbit a tiny star, completing each lap in just 1.52 days. It joins a small number of worlds that pose a fascinating puzzle - there are currently no known formation pathways for such chonkin' planets around such small stars.
It's called Messier 57, AKA the Ring Nebula, a glowing circle of gas in the constellation of Lyra, some 2,750 light-years from Earth.
New observations of mud cracks made by NASA's Curiosity rover show that high-frequency, wet-dry cycling occurred in early Martian surface environments.
The galaxy, called JD1, is seen as it was when the universe was only 480 million years old, or 4% of its present age.
A record-breaking binary system has been found with a rotation so tight, both objects could comfortably fit inside the Sun.
The international team behind the discovery also found that this type of light, known as gamma rays, is surprisingly bright. That is, there's more of it than scientists had previously anticipated.
A newly discovered star is so large, bright, and strange that its appearance could be pointing us towards a clump of dark matter in the sky.
By using the Very Large Telescope and the Atacama Large Millimeter/submillimeter Array, astronomers have identified clumps in the thick material around a star named V960 Mon that could gravitationally collapse to form the seeds of planets like Jupiter.
This hypothetical planet is provisionally known as Planet 9. Computer simulations show it must be a very large planet, consisting of between four and eight times the mass of the Earth and at least ten times the distance of Pluto.
The “Einstein cross” pattern comprises four images of a distant supernova created by the gravitational lensing of its light as it passed a distant galaxy within a cluster of galaxies on its way to Earth.
