A new analysis of data collected by NASA’s Galileo spacecraft in 1997 has found strong evidence that the underground ocean of Jupiter’s moon Europa may be venting plumes of water vapor above the icy shell. The results appear in the journal Nature Astronomy. Artist’s illustration of Jupiter and Europa with …

One of the enduring puzzles in astrobiology is why we haven’t found any aliens yet — and it’s worth another look, in light of Breakthrough Listen’s latest (and unprecedented) effort to find some in a new survey of millions of stars in our galaxy. Astronomers estimate there are between 200 …

Earth is surrounded by a protective magnetic environment, the magnetosphere, which deflects a supersonic stream of charged particles from the Sun, known as the solar wind. As the particles flow around the Earth’s magnetosphere, it forms a highly turbulent boundary layer called the magnetosheath. In a new discovery, reported in …

A research team led by Rutgers University’s Professor Dennis Kent has documented a gradual shift in Earth’s orbit that repeats regularly every 405,000 years, playing a role in natural climate swings. Astrophysicists have long hypothesized that the cycle exists, but Professor Kent and co-authors have found the first verifiable physical …

The moon as it exists today is as desolate as planetoids come. It’s airless, geologically inert, and there’s no magnetic field. However, we know from the study of moon rocks brought back by the Apollo missions that the moon did once have a magnetic field. Scientists haven’t known why before, …

We lost one of our greatest scientific minds when the renowned physicist Stephen Hawking passed away several weeks ago. However, he did leave one last idea for the scientific community to mull over in his absence. Just 10 days before his death, Hawking and his colleague Thomas Hertog submitted a …
