Using data from NASA's Transiting Exoplanet Survey Satellite, scientists have identified an Earth-size world, called TOI 700 e, orbiting within the habitable zone of its star -- the range of distances where liquid water could occur on a…

A new model that accounts for the interplay of forces acting on newborn planets can explain two puzzling observations that have cropped up repeatedly among the more than 3,800 planetary systems cataloged to date. One puzzle known as the…

Astronomers led by the University of Warwick have identified the oldest star in our galaxy that is accreting debris from orbiting planetesimals, making it one of the oldest rocky and icy planetary systems discovered in the Milky Way. Their…

Seismologists from The Australian National University (ANU) have developed a new method to scan the deep interior of planets in our solar system to confirm whether they have a core at the heart of their existence.   The scanning method,…

NASA's Mars rovers strive for groundbreaking scientific discoveries as they traverse the Martian landscape. At the same time, the crews operating the rovers do all they can to protect them and the billions of dollars behind the mission.…

After 10 months flying in space, NASA's Double Asteroid Redirection Test (DART) -- the world's first planetary defense technology demonstration -- successfully impacted its asteroid target on Monday, the agency's first attempt to move an…

NASA's DART spacecraft successfully slammed into a distant asteroid at hypersonic speed on Monday in the world's first test of a planetary defense system, designed to prevent a potential doomsday meteorite collision with Earth.Humanity's…

Its egg-like shape and craggy, boulder-dotted surface finally came into clear view in the last few minutes, as DART raced toward it at roughly 14,500 miles (23,500 kilometers) per hour. …

<!-- -->The mission has set the global astronomy community abuzzLaurel, US: Bullseye: A NASA spaceship on Monday struck an asteroid seven million miles away in order to deflect its orbit, succeeding in a historic test of humanity's…

TECHNICALLY CHALLENGING Minutes after impact, a toaster-sized satellite called LICIACube, which already separated from DART a few weeks ago, was expected to make a close pass of the site to capture images of the collision and the ejecta -…
