Astronomers discovered the first pair of merging quasars from the Cosmic Dawn, 900 million years after the Big Bang.
Jupiter's Great Red Spot (GRS) is one of the Solar System's defining features. It's a massive storm that astronomers have observed since the 1600s. However, its date of formation and longevity are up for debate.
A lot as changed in the 4.5 billion or so years since the Solar System first came together from a disk-shaped cloud of swirling dust and gas.
NASA’s Voyager 1 spacecraft is conducting normal science operations for the first time following a technical issue that arose in November 2023.
Deep beneath our feet, in the heart of our planet, something unexpected is happening. Scientists have discovered that Earth’s inner core, a solid iron-nickel sphere roughly the size of the moon, is slowing down.
Scientists have grappled with the fundamental forces that govern our universe, chief among them being gravity, and more recently, dark matter.
In addition to producing auroras, a recent extreme storm provided more detail on how much radiation future astronauts could encounter on the Red Planet.
Morning images show frost briefly coating at least four colossal volcanoes: Olympus Mons, Arsia Mons, Ascraeus Mons, and Ceraunius Tholus.
Cold, dense clouds in the interstellar medium of our Milky Way Galaxy are around four-five orders of magnitude denser than their diffuse counterparts.
The Milky Way is only as massive as it is because of collisions and mergers with other galaxies.
A neutron star labeled ASKAP J1935+2148 defies rules for neutron stars, emitting radio signals on a comparatively leisurely interval of 53.8 minutes.
The creation of any heavier elements would consume energy instead of releasing it. In order to explain the presence of these heavier elements today, it's necessary to find phenomena that can produce them.
Using the SHARK-VIS instrument on the Large Binocular Telescope on Mount Graham in Arizona, the United States, astronomers have captured the highest resolution optical images of Io ever obtained from a ground-based telescope.
China launched a probe to collect samples from the far side of the moon, a world first as Beijing pushes ahead with an ambitious program that aims to send a crewed lunar mission by 2030.
New research demonstrated a possible formation mechanism of intermediate-mass black holes in globular clusters, star clusters that could contain tens of thousands or even millions of tightly packed stars.
