Ultraviolet Shines Light on Origins of the Solar System

In the search to discover the origins of our solar system, an international team including planetary scientists has compared the composition of the sun to the composition of the most ancient ...

Two Planets Around a Red Dwarf

Astronomers have detected two exoplanets orbiting the star TOI-1266. The telescope thus demonstrates its high precision and takes an important step in the quest of finding potentially habitable ...
A long discussed theory about the local magnetic spots of the moon suggests that they are the result of magnetization processes caused by impacts of massive bodies on the ...

The Mountains of Pluto Are Snowcapped, but Not for the Same Reasons as on Earth

In 2015, the New Horizons space probe discovered spectacular snowcapped mountains on Pluto, which are strikingly similar to mountains on Earth. Such ...

First Study With CHEOPS Data Describes One of the Most Extreme Planets in the Universe

CHEOPS keeps its promise: Observations with the space telescope reveal details of the exoplanet WASP-189b - one of the most extreme planets ...

Pair of Massive Baby Stars Swaddled in Salty Water Vapor

Astronomers spotted a pair of massive baby stars growing in salty cosmic soup. Each star is shrouded by a gaseous disk which includes molecules of sodium chloride, commonly known as table salt, and ...

Remnants of an Ancient Asteroid Shed New Light on the Early Solar System

Researchers have shaken up a once accepted timeline for cataclysmic events in the early solar system. Geological and geochemical records indicate that the Earth-Moon system experienced a period of ...

Centuries-Old Conjecture About Formation of the Solar System Verified

Using a limited set of mathematical equations, a mathematical sciences professor said he has confirmed a 224-year-old math conjecture about the origins of our solar system, providing insights about ...

Can Ripples on the Sun Help Predict Solar Flares?

Scientists discovered in 1996 that sunquakes are linked to solar flares. Now, using helioseismic holography, scientists have analyzed a 2011 flare and shown that the impulsive source that generated ...

NASA's IRIS Spots Nanojets: Shining Light on Heating the Solar Corona

Researchers report the first ever clear images of nanojets -- bright thin lights that travel perpendicular to the magnetic structures in the solar atmosphere, called the corona -- in a process that ...

Comet 67P/Churyumov-Gerasimenko has its own far-ultraviolet aurora, data reveal. It is the first time such electromagnetic emissions in the far-ultraviolet have been documented on a celestial object ...

Asteroid Ryugu's Rocky Past

Researchers have found evidence that asteroid Ryugu was born out of the possible destruction of a larger parent asteroid millions of years ...

Solar Storm Forecasts for Earth Improved With Help from the Public

Scientists used observations recorded by members of the public to increase accuracy of computer model predictions of when harmful CMEs will hit ...

Can Life Survive a Star's Death? Webb Telescope Can Reveal the Answer

When stars like our sun die, all that remains is an exposed core -- a white dwarf. A planet orbiting a white dwarf presents a promising opportunity to determine if life can survive the death of its ...

Enormous Planet Quickly Orbiting a Tiny, Dying Star

Thanks to a bevy of telescopes in space and on Earth -- and even a pair of amateur astronomers in Arizona -- astronomers have discovered a Jupiter-sized planet orbiting at breakneck speed around a ...

Modern Theory from Ancient Impacts

It is generally accepted that the inner region of the early solar system was subject to an intense period of meteoric bombardment referred to as the late heavy bombardment. However, researchers have ...

From Star to Solar System: How Protoplanetary Rings Form in Primordial Gas Clouds

The star HL Tauri is glowing at the center of a system of concentric rings made from gas and dust and producing planets, one for each gap in the ring. Its discovery has shaken solar system origin ...

Carbon-Rich Exoplanets May Be Made of Diamonds

Astronomers have determined that some carbon-rich exoplanets, given the right circumstances, could be made of diamonds and ...

Giant Particle Accelerator in the Sky

A new study shows that electrons in the radiation belts can be accelerated to very high speeds locally. The study shows that magnetosphere works as a very efficient particle accelerator speeding up ...

Sand-Sized Meteoroids Are Peppering Asteroid Bennu

A new study posits that the major particle ejections off the near-Earth asteroid Bennu may be the consequence of impacts by small, sand-sized particles called meteoroids onto its surface as the ...

Meteorites Show Transport of Material in Early Solar System

New studies of a rare type of meteorite show that material from close to the Sun reached the outer solar system even as the planet Jupiter cleared a gap in the disk of dust and gas from which the ...
