NASA has selected eight participating scientists to join its Lucy mission to the Jupiter Trojan asteroids. These asteroids are remnants of our early

Binary asteroids have attracted the attention of the scientific community due to their interesting properties and the significant impact they have on our understanding of the Solar System.

The Earth was hit Monday by an intense solar storm that could bring the northern lights to night skies further south than normal, a US agency announced.

The Gaia mission has revealed hundreds of asteroids with possible moons. The info comes from precise measurements of orbits of more than 150,000 asteroids. The post Gaia spots over 350 asteroids with possible moons first appeared on EarthSky.

As Apophis passes closer to Earth than geosynchronous satellites in April 2029, the asteroid will hopefully be tracked by a new ESA mission called Ramses.

During a gravity assist with Mars, Hera will study the moon Deimos.

The great planetary instability, which saw Jupiter and the other gas giants wander chaotically through the solar system, coincides with the collision that formed Earth's moon. Could the two events be linked?

Scientists revealed the extent of the impact DART had on its targets Dimorphos and Didymos, including the "amazing" amount of material it blasted away.

ETH Zurich researcher Luca Dal Zilio offers an insightful summary of the recent earthquakes in Turkey and Syria, shedding light on the complex nature of this event. He discusses the lessons that can be drawn from it to better understand and prepare for future seismic occurrences in the region.

The Lucy spacecraft and its target asteroids show that the way that we name discoveries matters

The MICROSCOPE mission tested the weak equivalence principle with free-falling objects in a satellite

Our host star is middle-aged, but we must come to terms with its mortality.

The European Southern Observatory's Very Large Telescope Interferometer (ESO's VLTI) has observed a cloud of cosmic dust at the centre of the galaxy Messier 77 that is hiding a supermassive black hole. The findings have confirmed predictions made around 30 years ago and are giving astronomers new insight into "active galactic nuclei", some of the brightest and most enigmatic objects in the universe.

Using four telescope units of ESO's Very Large Telescope, astronomers have now probed deep inside the atmosphere of the ultrahothot-Jupiter exoplanet WASP-121b and revealed distinct powerful winds in separate layers, forming a map of the atmosphere's 3D structure.

Thirty years ago, on 16 July 1994, astronomers watched in awe as the first of many pieces of the Shoemaker-Levy 9 comet slammed into Jupiter with incredible force. The event sparked intense interest in the field of planetary defense as people asked: "Could we do anything to prevent this happening to Earth?"

EL chondrite meteorites come from the Athor family of asteroids, the progenitor of which was dumped in the asteroid belt by the migrating gas giants between ...

'In a way, we've gotten closure on a question that started with James Clerk Maxwell."

A core principle of Einstein's general theory of relativity has just passed its most stringent test yet.

Recently, scientists from NASA's OSIRIS-REx mission discovered that surface regeneration occurs on asteroids far more quickly than on Earth. By analyzing high-resolution images of rock fractures on asteroid Bennu taken by the OSIRIS-REx spacecraft, the researchers discovered that the Sun's heat frac

Observations of faraway worlds have forced a near-total rewrite of the story of our solar system.
