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 Earth.

Hubble captures crisp new portrait of Jupiter's storms
Hubble's sharp view is giving researchers an updated weather report on the monster planet's turbulent atmosphere, including a remarkable new storm brewing, and a cousin of the famous Great Red Spot region gearing up to change color -- again.

Venus' ancient layered, folded rocks point to volcanic origin
Researchers has found that some of the oldest terrain on Venus, known as tesserae, have layering that seems consistent with volcanic activity. The finding could provide insights into the enigmatic planet's geological history.

Climate change impacts astronomical observations
Already, climate change is having an impact on the conditions of space observation at the Very Large Telescope in the Atacama Desert. In future, new telescopes will have to be adapted to the expected changes, a new study.

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 star, according to researchers.

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 distant white dwarf star.

Scientist searches for stellar phosphorus to find potentially habitable exoplanets
A scientist has identified stellar phosphorus as a probable marker in narrowing the search for life in the cosmos. She has developed techniques to identify stars likely to host exoplanets, based on the composition of stars known to have planets, and proposes that upcoming studies target stellar phosphorus to find systems with the greatest probability for hosting life as we know it.

Device could help detect signs of extraterrestrial life
Although Earth is uniquely situated in the solar system to support creatures that call it home, different forms of life could have once existed, or might still exist, on other planets. But finding traces of past or current lifeforms on other worlds is challenging. Now, researchers have developed a fully automated microchip electrophoresis analyzer that, when incorporated into a planetary rover, could someday detect organic biosignatures in extraterrestrial soil.

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 found evidence that suggests this period occurred slightly earlier than thought and was less intense but also more prolonged. Such details about this period could impact theories about the early Earth and the dawn of life.

Unraveling a spiral stream of dusty embers from a massive binary stellar forge
With almost two decades of mid-infrared imaging from the largest observatories around the world including the Subaru Telescope, a team of astronomers was able to capture the spiral motion of newly formed dust streaming from the massive and evolved binary star system WR112. The study reveals the motion of the dusty outflow from the system and identifies WR112 as a highly efficient dust factory that produces an entire Earth mass of dust every year.

Study shows difficulty in finding evidence of life on Mars
While scientists are eager to study the red planet's soils for signs of life, researchers must ponder a considerable new challenge: Acidic fluids - which once flowed on the Martian surface - may have destroyed biological evidence hidden within Mars' iron-rich clays, according to researchers.

A warm Jupiter orbiting a cool star
A planet observed crossing in front of, or transiting, a low-mass star has been determined to be about the size of Jupiter.

Possible marker of life spotted on venus
Astronomers have discovered a rare molecule -- phosphine -- in the clouds of Venus. On Earth, this gas is only made industrially or by microbes that thrive in oxygen-free environments. Astronomers have speculated for decades that high clouds on Venus could offer a home for microbes -- floating free of the scorching surface but needing to tolerate very high acidity. The detection of phosphine could point to such extra-terrestrial 'aerial' life.

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 silica.

New Hubble data suggests there is an ingredient missing from current dark matter theories
Recent observations have found that something may be missing from the theories of how dark matter behaves. This missing ingredient may explain why researchers have uncovered an unexpected discrepancy between observations of the dark matter concentrations in a sample of massive galaxy clusters and theoretical computer simulations of how dark matter should be distributed in clusters.

Jupiter's moons could be warming each other
The gravitational push and pull by Jupiter's moons could account for more warming than the gas giant Jupiter alone.

Revealing the secrets of high-energy cosmic particles
The 'IceCube' neutrino observatory deep in the ice of the South Pole has already brought spectacular new insights into cosmic incidents of extremely high energies. Astronomers observe the light that comes to us from distant celestial objects to explore the Universe. However, light does not tell us much about the highest energy events beyond our Galaxy, such as the jets of active galactic nuclei, gamma-ray bursts or supernovae, because photons in the upper gamma-ray range lose their extreme energies on their long way through the Universe through interaction with other particles.

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 electrons to so-called ultra-relativistic energies.

Massive halo finally explains stream of gas swirling around the Milky Way
Astronomers have discovered that a halo of warm gas surrounding the Magellanic Clouds likely acts as a protective cocoon, shielding the dwarf galaxies from the Milky Way's own halo and contributing most of the Magellanic Stream's mass.

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 object nears the Sun.
