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.
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.
