Observing the birth of a quasiparticle
Over the past decades, physicists worldwide have been trying to gain a better understanding of non-equilibrium dynamics in quantum many-body systems. Some studies investigated what are known as quasiparticles, disturbances or entities in physical sys.....»»
The sun was born when a dense gas cloud collapsed 4.6 billion years ago
While the upcoming total solar eclipse is a special moment to reflect on our place in the universe, scientists have been studying the birth of the sun and the formation of our solar system for a long time......»»
Eclipses were once associated with the deaths of kings—predictions played a key role in the birth of astronomy
Making interesting predictions is one of the hallmarks of successful science. When Albert Einstein formulated his theory of general relativity, an almost immediate test involved the prediction that in a solar eclipse, light from stars that would norm.....»»
Student cleans up archival data and uncovers two stellar cocoons
While investigating 16 years of images of young stars from a retired astronomical camera, Leiden master's student Sam de Regt discovered that two of those stars were still enveloped in birth clouds that had not been seen at this level of detail befor.....»»
Supercomputer simulations decode the mass puzzle of the first stars
Ching-Yao Tang and Dr. Ke-Jung Chen from the Institute of Astronomy and Astrophysics, Academia Sinica (ASIAA) have made substantial progress in decoding the birth mass of the first stars using the powerful supercomputer at Berkeley National Lab......»»
Easily observing environmental pollution-causing harmful substances through a mobile phone camera

New NASA software simulates science missions for observing terrestrial freshwater
From radar instruments smaller than a shoebox to radiometers the size of a milk carton, there are more tools available to scientists today for observing complex Earth systems than ever before. But this abundance of available sensors creates its own u.....»»
Researchers observe salt dissolution at the atomic level
A research team, affiliated with UNIST has achieved a groundbreaking feat by observing the dissolution of salt in water at the atomic level and experimentally uncovering the underlying principle......»»
Stunning James Webb images show birth and death of massive stars
The James Webb Space Telescope continues to surprise us with stunning pictures, but of what exactly? Astronomer Nienke van der Marel shows with three images how massive stars lead short but explosive lives......»»
"Dark stars": Dark matter may form exploding stars, and observing the damage could help reveal what it"s made of
Dark matter is a ghostly substance that astronomers have failed to detect for decades, yet which we know has an enormous influence on normal matter in the universe, such as stars and galaxies. Through the massive gravitational pull it exerts on galax.....»»
Bedtime or go time? Observing what animals do during a total solar eclipse
When darkness falls on central Ohio during the total solar eclipse on April 8, will animals think it's time to go to bed? Will they be anxious? Will they care?.....»»
What heat can tell us about battery chemistry: Using the Peltier effect to study lithium-ion cells
Batteries are usually studied via electrical properties like voltage and current, but new research suggests that observing how heat flows in conjunction with electricity can give important insights into battery chemistry......»»
Kala, rare Sumatran tiger cub, makes her debut in Rome
A run around and a cuddle with dad—Rome zoo's new Sumatran tiger cub made her public debut Thursday, three months after her birth boosted the critically endangered species......»»
Fewer fish and more algae? Scientists seek to understand impacts of historic lack of Great Lakes ice
Michigan Tech University biologists have been observing a remote Lake Superior island's fragile wolf population every winter since 1958, but they had to cut this season's planned seven-week survey short after just two weeks......»»
See what James Webb and Hubble are observing right now with this tool
If you're looking for a relaxing way to observe the fascinating sights of space on your lunch break, then a newly updated tool from NASA has you covered......»»
Groundbreaking survey reveals secrets of planet birth around dozens of stars
In a series of studies, a team of astronomers has shed new light on the fascinating and complex process of planet formation. The stunning images, captured using the European Southern Observatory's Very Large Telescope (ESO's VLT) in Chile, represent.....»»
What ended the "dark ages" in the early universe? New Webb data just brought us closer to solving the mystery
About 400,000 years after the Big Bang, the cosmos was a very dark place. The glow of the universe's explosive birth had cooled, and space was filled with dense gas —mostly hydrogen—with no sources of light......»»
Scientists discover radiation from massive stars shapes planetary systems
How do planetary systems such as the solar system form? To find out, CNRS scientists taking part in an international research team studied a stellar nursery, the Orion Nebula, using the James Webb Space Telescope. By observing a protoplanetary disk n.....»»
Old European satellite plunges harmlessly through the atmosphere over the Pacific
An old Earth-observing satellite fell out of orbit Wednesday and harmlessly broke apart over the Pacific......»»
Hubble spots a massive star forming amid clouds of dust and gas
A stunning new image from the Hubble Space Telescope shows the birth of a new, massive star at around 30 times the mass of our sun......»»
Toxoplasmosis: Researchers identify protein that evolved alongside infection machinery
Toxoplasmosis is an infectious disease found worldwide, caused by the single-celled parasite Toxoplasma gondii. In humans, infection poses a particular risk to pregnant women, as it can lead to birth defects. Like the closely related malaria pathogen.....»»
