Astronomers investigate long-term variability of blazar AO 0235+164
Astronomers have performed a comprehensive multiwavelength study of an extremely variable blazar known as AO 0235+164. Results of the new study, published Nov. 3 on the preprint server arXiv, shed more light on the long-term variability and behavior.....»»
Happy New Year on Mars
12 November 2024 marks the start of a new year on Mars. At exactly 10:32 CET/09:32 UTC on Earth, the Red Planet begins a new orbit around our sun......»»
AI-enhanced model could improve space weather forecasting
"Killer electrons" that travel at nearly light speed inside Earth's Van Allen belts—the zone that surrounds the planet and traps energetic charged particles—pose a major threat to equipment in space by causing malfunctions in electronics......»»
Swirling polar vortices likely exist on the sun, new research finds
Like the Earth, the sun likely has swirling polar vortices, according to new research led by the U.S. National Science Foundation National Center for Atmospheric Research (NSF NCAR). But unlike on Earth, the formation and evolution of these vortices.....»»
Was "Snowball Earth" a global event? New study delivers best proof yet
Geologists have uncovered strong evidence from Colorado that massive glaciers covered Earth down to the equator hundreds of millions of years ago, transforming the planet into an icicle floating in space......»»
Team reveals how current sheets in turbulent plasma form in Earth"s magnetosheath
Magnetic reconnection is a fundamental physical process in plasmas, through which the magnetic energy is converted into plasma kinetic energy and thermal energy rapidly. Current sheets in turbulent plasma are the key trigger for magnetic reconnection.....»»
Quasi-periodic eruptions from eRO-QPE2 are remarkably stable, study finds
An international team of astronomers has inspected long-term evolution of quasi-periodic eruptions (QPEs) from a QPE source designated eRO-QPE2. The study found that QPEs from this source are remarkably stable over the investigated period of over thr.....»»
Thousands flee as fourth major storm in a month hits Philippines
Thousands of people sought shelter, ports were shut down and landslides blocked mountain roads in the Philippines on Monday, as the disaster-weary nation was struck by a fourth cyclone in less than a month......»»
White truffles, Italy"s gold, menaced by climate change
Deep in a thick forest in Italy's northwestern Piedmont region, the hunt is on for the white Alba truffle, with excited dogs zigzagging and digging into the wet earth......»»
Hubble captures barred spiral galaxy NGC 1672
This NASA/ESA Hubble Space Telescope image features NGC 1672, a barred spiral galaxy located 49 million light-years from Earth in the constellation Dorado. This galaxy is a multi-talented light show, showing off an impressive array of different celes.....»»
Powerful new US-Indian satellite will track Earth"s changing surface
Data from NISAR will improve our understanding of such phenomena as earthquakes, volcanoes, and landslides, as well as damage to infrastructure......»»
Geologists rewrite textbooks with new insights from Cambrian rocks of Grand Canyon
Since soon after our planet formed, Earth's 4.6 billion-year-long history was dominated by single-celled life. Something dramatic happened about 500 million years ago called the Cambrian "explosion," during which an incredible diversity of life forms.....»»
Planetary Boundaries framework gains traction in sustainability science
The Planetary Boundaries (PB) framework is a pivotal tool for tackling the climate crisis and safeguarding humanity's future on Earth. For the first time, the full story of the Planetary Boundaries is now being told from its beginning......»»
Cracked earth in Greece"s saffron heartland as drought takes toll
At a field outside Kozani, northern Greece, the strikingly blue-and-purple petals of saffron give off an intoxicating scent that underscores the value of one of the country's most lucrative crops......»»
Astronaut’s photo shows Earth as you’ve never seen it before
NASA's oldest serving astronaut has shared an image taken from the space station that shows Earth in a most unusual way......»»
Advances in plate tectonics research provide a new view of deep Earth"s carbon emissions
From time to time, when Earth's tectonic plates shift, the planet emits a long, slow belch of carbon dioxide. In a new modeling study published in Geochemistry, Geophysics, Geosystems, R. Dietmar Müller and colleagues show how this gas released from.....»»
Q&A: Looking at ancient Roman plagues through an environmental lens
A pit of human bones, potential evidence of a catastrophic epidemic that struck Constantinople in 541 A.D. Sulfur deposits trapped in polar ice, showing traces of a series of massive volcanic eruptions. For Brandon McDonald, these seemingly incongruo.....»»
Nearly three years since launch, Webb is a hit among astronomers
Demand for observing time on Webb outpaces supply by a factor of nine. From its halo-like orbit nearly a million miles from Earth, the James Webb Space Telescope is seeing farther.....»»
