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.
French researchers suggesting that the tallest volcano in Solar System, Olympus Mons on Mars was once a volcanic island, surrounded by a deep sea.
This observation suggests exciting avenues of investigation into both the production of cosmic dust and the earliest stellar populations in our Universe, and was made possible by Webb’s unprecedented sensitivity.
A strange radio signal pulsing from a spot 15,000 light-years away could point to an unconfirmed type of star.
Data collected by the BepiColombo spacecraft traces the causes of the strange aurora, which course through the planet's weak magnetosphere.
International research has found the first evidence of a massive galaxy with no dark matter. The result is a challenge to the current standard model of cosmology.
The world's first 16-megawatt monster offshore wind turbine is now connected to the power grid. This towering colossus will supply clean energy for about 36,000 Chinese homes.
Australian scientists have invented a next-generation solar panel capable of healing itself when damaged in space.
Exoplanet WASP-193b, is nearly 50 % bigger than Jupiter but it's so light and fluffy that its overall density is comparable to that of cotton candy. It's just a hair over 1% of the density of Earth.
NASA's Juno spacecraft orbiting Jupiter frequently encounters giant swirling waves at the boundary between the solar wind and Jupiter's magnetosphere.
An unidentified source has been beaming out a pulse of radio waves every 22 minutes since 1988, astronomers say.
Scientists are seeking to confirm that a black rock discovered in Morocco in 2018 departed Earth's pull for outer space, only to return to it like a prodigal child.
In a first, the James Webb Space Telescope (JWST) may have glimpsed a rare type of star that astronomers aren’t even sure exists. These “dark stars” might not have been fueled not by nuclear fusion but by the self-annihilation of dark matter.
A retired cosmological theory should be given a second chance at explaining anomalies in our Universe, according to theoretical physicist Rajendra Gupta from the University of Ottawa in Canada.
