Comet discovered to have its own northern lightsComet 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 other than a planet or moon.Ancient volcanoes once boosted ocean carbon, but humans are now far outpacing themA new study of an ancient period that is considered the closest natural analog to the era of modern human carbon emissions has found that massive volcanism sent great waves of carbon into the oceans over thousands of years -- but that nature did not come close to matching what humans are doing today.Possible marker of life spotted on VenusAstronomers 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.New Hubble data suggests there is an ingredient missing from current dark matter theoriesRecent 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.High-fidelity record of Earth's climate history puts current changes in contextScientists have compiled a continuous, high-fidelity record of variations in Earth's climate extending 66 million years into the past. The record reveals four distinctive climate states, which the researchers dubbed Hothouse, Warmhouse, Coolhouse, and Icehouse. These major climate states persisted for millions and sometimes tens of millions of years, and within each one the climate shows rhythmic variations corresponding to changes in Earth's orbit around the sun.How coronavirus took hold in North America and in EuropeEarly interventions were effective at stamping out coronavirus infections before they spread, according to a new study. Combining virus genomics with epidemiologic simulations and travel records, the research shows that in both the United States and in Europe, sustained transmission networks became established only after separate introductions of the virus that went undetected.COVID-19 study links strict social distancing to much lower chance of infectionUsing public transportation, visiting a place of worship, or otherwise traveling from the home is associated with a significantly higher likelihood of testing positive with the coronavirus SARS-CoV-2, while practicing strict social distancing is associated with a markedly lower likelihood.Unconscious learning underlies belief in God, study suggestsIndividuals who can unconsciously predict complex patterns, an ability called implicit pattern learning, are likely to hold stronger beliefs that there is a god who creates patterns of events in the universe, according to neuroscientists.

Solar Cycle 25 has arrived. Here’s what to expect from the Sun in the coming months and years
The sun goes through a regular 11-year cycle, swinging between periods of dormancy and periods of activity. Scientists from NASA and NOAA have just announced that the sun has just passed its minimum, and will be ramping up in activity over the next few years, meaning that we have entered a new round of the …

The asteroid belt is a chaotic place. Things smash into each other, get thrown into completely different orbital planes, and are occasionally visited by small electronic spacecraft launched by humans. All three things seem to have happened to the asteroid Bennu, which is currently being orbited by OSIRIS-REx, a mission launched by NASA in 2016. …

Gravity is good for a lot of things. It brings objects closer together. Occasionally they crash into each other. But sometimes two objects get locked in a unique gravitational dance that pairs them together. That dance can be short-lived, or it can last for billions of years. In some cases the objects are large (i.e. …

Coronavirus measures for hosted meetings and visitorsSatcom to foster resilient digital systems
Telecommunications are becoming increasingly crucial to our society, economy and security. ESA is supporting the European satellite communication industry’s efforts to identify how to meet future worldwide demands for more secure and resilient digital systems.Summit of technical excellenceImage: Summit of technical excellenceOur seas are capturing more carbon than expected
Earth’s oceans help to slow global warming by absorbing carbon from our atmosphere – but fully observing this crucial process in the upper ocean and lower atmosphere is difficult, as measurements are taken not where it occurs, the sea surface, but several metres below. New research uses data from ESA, NASA and NOAA satellites to rectify this, and finds that far more carbon is absorbed by the oceans than previously thought.SEOSAT-Ingenio soon to be launchedVideo: 00:05:00
The Spanish high-resolution land imaging mission, known as SEOSAT-Ingenio, will soon be shipped from Airbus, in Madrid, to Europe’s Spaceport in French Guiana - where it will be prepared for launch later this year on a Vega rocket. The Earth-observing satellite carries a state-of-the-art dual camera that can image Earth’s land with a resolution of 2.5 m. The mission will benefit society through numerous disciplines such as cartography, agriculture, forestry, urban development and water management.With its capability to look sideways, it can access any point on Earth within three days, and will be used to help map natural disasters such as floods, wildfires and earthquakes – as well as help with one of humankind’s...Plans underway for new polar ice and snow topography mission

Over the past month, dozens of wildfires have burned vast swathes of land in California, Oregon and Washington State, killing more than 30 people and smothering the majority of the western United States in smoke. While photographs have circulated online showing the apocalyptic orange skies, satellites in orbit around Earth carry different instruments that can provide not only images, but a wealth of complementary information needed to monitor the blazes.A new view of EnceladusImage: A new view of Enceladus
