Astronomers detect ancient lonely quasars with murky origins
A quasar is the extremely bright core of a galaxy that hosts an active supermassive black hole at its center. As the black hole draws in surrounding gas and dust, it blasts out an enormous amount of energy, making quasars some of the brightest object.....»»
Astronomers observe a strong superflare from giant star
Using the Neutron Star Interior Composition Explorer (NICER) and various ground-based telescopes, an international team of astronomers have performed observations of a strong X-ray superflare which occurred in 2022 on a giant star known as HD 251108......»»
Where to find Ancient Debris and Netherite Ingots in Minecraft
Nether Ingots can help create some very strong tools and armor, but they can be tricky to make. If you're unsure how to craft this material, we can help you!.....»»
Ancient climate analysis reveals unknown global processes
According to highly cited conventional models, cooling and a major drop in sea levels about 34 million years ago should have led to widespread continental erosion and deposited gargantuan amounts of sandy material onto the ocean floor. This was, afte.....»»
Saturday Citations: All that sparkles is plastic; woke tree diversity; the gravitational basin in which we reside
This week, astronomers considered whether dark energy varies over cosmic timescales. Via neutron analysis, physicists revealed that some Early Iron Age swords were altered recently by swindlers in order to be more historically exciting. And a profess.....»»
The Origins of the Climate Haven Myth
In a world of increasingly powerful hurricanes and other rising climate threats, those with vested interests in promoting certain locations have sold the public a dream......»»
Novel algorithms detect precursory scale increase to help forecast big quakes
Many people are aware that large earthquakes are often followed by a sequence of aftershocks as stresses are redistributed in the surrounding area. Many may not be aware that there are also sequences of earthquakes that occur before most large earthq.....»»
AI decodes microbes" message in milk safety testing approach
By combining the genetic sequencing and analysis of the microbes in a milk sample with artificial intelligence (AI), researchers were able to detect anomalies in milk production, such as contamination or unauthorized additives. The new approach could.....»»
"Inside-out" galaxy growth observed in the early universe
Astronomers have used the NASA/ESA James Webb Space Telescope (JWST) to observe the 'inside-out' growth of a galaxy in the early universe, only 700 million years after the Big Bang......»»
Asteroid mining: A potential trillion-dollar industry
Earth's newest celestial neighbor has finally arrived. Astronomers using a powerful telescope in Sutherland, South Africa, first detected the 33-foot-long asteroid in August, reporting their discovery in Research Notes of the American Astronomical So.....»»
Astronomers find Webb data conflict with reionization models
Reionization is a critical period when the first stars and galaxies changed the physical structure of their surroundings, and eventually the entire universe. Established theories state that this epoch ended around 1 billion years after the Big Bang......»»

Jupiter"s Great Red Spot shows unexpected size changes
Astronomers have observed Jupiter's legendary Great Red Spot (GRS), an anticyclone large enough to swallow Earth, for at least 150 years. But there are always new surprises—especially when NASA's Hubble Space Telescope takes a close-up look at it......»»
Astronomers race to capture image of exoplanet near star
Planet AF Lep b is a world of firsts. In 2023, it was the lowest-mass planet outside our solar system to be directly observed and have its mass measured using astrometry. This is a technique that charts the subtle movements of a host star over many y.....»»
