Scientists studying a distant galaxy cluster have discovered the biggest explosion seen in the Universe since the Big Bang. The blast came from a supermassive black hole at the centre of a galaxy hundreds of millions of light-years away. It released five times more energy than the previous record holder.
The latest image from the international Gemini Observatory showcases the striking planetary nebula CVMP 1. This object is the result of the death throes of a giant star and is a glorious but relatively short-lived astronomical spectacle. As the progenitor star of this planetary nebula slowly cools, this celestial hourglass will run out of time and will slowly fade from view over many thousands of years.
Astronomers have found an exoplanet more than twice the size of Earth to be potentially habitable, opening the search for life to planets significantly larger than Earth but smaller than Neptune.
Scientists have devised new analytical tools to break down the enigmatic history of Mars' atmosphere -- and whether life was once possible there. A paper detailing the work was published today in the journal Science Advances. It could help astrobiologists understand the alkalinity, pH and nitrogen content of ancient waters on Mars, and by extension, the carbon dioxide composition of the planet's ancient atmosphere.
More than a year after NASA's Mars InSight lander touched down in a pebble-filled crater on the Martian equator, the rusty red planet is now serving up its meteorological secrets: gravity waves, surface swirling "dust devils," and the steady, low rumble of infrasound, Cornell and other researchers have found.
These latest Hubble observations of the Sombrero galaxy indicate only a tiny fraction of older, metal-poor stars in the halo, plus an unexpected abundance of metal-rich stars. Past major galaxy mergers are a possible explanation, though the stately Sombrero shows none of the messy evidence of a recent merger of massive galaxies.
An international team of astronomers used two of the most powerful radio telescopes in the world to create more than three hundred images of planet-forming disks around very young stars in the Orion Clouds. These images reveal new details about the birthplaces of planets and the earliest stages of star formation.
A signal originally detected by the Kepler spacecraft has been validated as an exoplanet using the Habitable-zone Planet Finder.
Astronomers from the University of Warwick have observed an exoplanet orbiting a star in just over 18 hours, the shortest orbital period ever observed for a planet of its type.
MIT engineers devise a decision map to identify the best mission type to deflect an incoming asteroid.
