Researchers have found that water on Comet 67P/Churyumov–Gerasimenko has a similar molecular signature to the water in Earth's oceans. Contradicting some recent results, this finding reopens the case that Jupiter-family comets ...
Panspermia is the hypothesis that life can survive the transfer between planetary bodies as a secondary path for life to get started on planets throughout a solar system. The discovery of extraterrestrial life on asteroids ...
An international team led by researchers in Japan and Europe has discovered a new multi-planet system around a sun-like star, including an ultra-short period planet with one of the highest densities ever measured. The findings, ...
Mount Vesuvius, Krakatoa, Mount St. Helens: Since the formation of Earth approximately 4.5 billion years ago, the convection and release of hot magma in its mantle layer has famously led to some of the deadliest eruptions ...
Tiny grains from a distant asteroid are revealing clues to the magnetic forces that shaped the far reaches of the solar system more than 4.6 billion years ago.
Since its launch in late 2021, NASA's James Webb Space Telescope has raised the possibility that we could detect signs of life on exoplanets, or planets outside our solar system.
Astronomers report the detection of a second exoplanet orbiting a G-type star known as TIC 393818343, located some 300 light years away. The newfound alien world is about three times less massive than Jupiter. The finding ...
Researchers have used the chemical fingerprints of zinc contained in meteorites to determine the origin of volatile elements on Earth. The results suggest that without 'unmelted' asteroids, there may not have been enough ...
An international coalition led by Oregon State University scientists concludes in its annual report published in BioScience that the Earth's worsening vital signs indicate a "critical and unpredictable new phase of the climate ...
It is a major goal of astronomical research to find planets other than Earth that might be suitable for sustaining life. There are a number of factors which many scientists agree are essential to a planet being habitable, ...
