Mars orbiter spots retired InSight lander to study dust movement

NASA's Mars Reconnaissance Orbiter (MRO) caught a glimpse of the agency's retired InSight lander recently, documenting the accumulation of dust on the spacecraft's solar panels. In the new image taken Oct. 23 by MRO's High-Resolution ...

Does the exoplanet TRAPPIST-1 b have an atmosphere after all?

TRAPPIST-1 b is one of seven rocky planets orbiting the star TRAPPIST-1, located 40 light-years away. The planetary system is unique because it allows astronomers to study seven Earth-like planets from relatively close range, ...

EU kickstarts satellite network to rival Musk's Starlink

The EU's flagship satellite constellation project officially took off Monday, as the bloc signed a concession contract with a European consortium to develop a secure space-based communication system.

Could planets orbiting two stars have moons?

Exomoons are a hot topic in the science community, as none have been confirmed with astronomers finding new and creative ways to identify them. But while astronomers have searched for exomoons orbiting exoplanets around single ...

Do the fastest-spinning pulsars contain quark matter?

Neutron stars are so named because in the simplest of models they are made of neutrons. They form when the core of a large star collapses, and the weight of gravity causes atoms to collapse. Electrons are squeezed together ...

Hubble images spiral galaxy NGC 5643

The spiral galaxy NGC 5643 is located roughly 40 million light-years away in the constellation Lupus, the Wolf. NGC 5643 is a grand design spiral, which refers to the galaxy's symmetrical form with two large, winding spiral ...

Japan's Space One delays Kairos rocket launch again

A startup aiming to become Japan's first private firm to put a satellite into orbit postponed a rocket launch for the second day running on Sunday, after its first try ended in a mid-air explosion.

Japan space firm postpones second attempt at orbit

A company aiming to become Japan's first private firm to put a satellite into orbit postponed its rocket launch on Saturday, after its first try ended in a mid-air explosion.

Astronomers discover more dark comets

The first dark comet—a celestial object that looks like an asteroid but moves through space like a comet—was reported less than two years ago. Soon after, another six were found. In a new paper, researchers announce the ...

Using Jupiter as a dark matter detector

The nature of dark matter has been a hotly debated topic for decades. If it's a heavy, slow moving particle, then it's just possible that neutrinos may be emitted during interactions with normal matter.
