How accurate are past records of sunspots? In a new study published in The Astrophysical Journal, a team of multinational researchers examined the historical record and found that after the unusual period of almost no sunspots, ...
Earthquake effects are often thought of in terms of the human impact, be that fatalities or destruction to homes and infrastructure. However, the environmental toll can also be damaging, and new research, published in Nature ...
The Paleocene–Eocene Thermal Maximum (PETM) is a period of global warming that occurred ~56 million years ago, lasting approximately 200,000 years, when the Earth experienced global surface temperature elevations of ~5°C.
Using the Circumgalactic H-alpha Spectrograph (CHαS), astronomers have performed spectroscopic observations of a nearby active galaxy designated Messier 77. They detected a very extended structure of ionized gas around this ...
An international team of astronomers reports the discovery of a new hyperluminous quasar. The newfound quasar, which received the designation eFEDSJ0828–0139, has a high star-formation rate and its black hole is accreting ...
India's Chandrayaan-3 mission was launched last summer and its Vikram lander touched down on the moon's surface last August. Shortly thereafter, it released a rover called Pragyan. Since that time, the rover has been meandering ...
Chinese astronomers have conducted multi-frequency polarimetric observations of a quasar known as 1604+159. Results of the observational campaign, published August 13 on the pre-print server arXiv, shed more light on the ...
An international team of astronomers reports the detection of a blazar with highly significant sinusoidal radio variability using the Owens Valley Radio Observatory (OVRO). The finding was detailed in a research paper published ...
Using seismic activity to probe the interior of Mars, geophysicists have found evidence for a large underground reservoir of liquid water—enough to fill oceans on the planet's surface.
