Challenging Previous Theories – Scientists Shed New Light on the Enigmatic Nature of Black Holes
Utilizing sophisticated simulation technology, researchers from UNIGE, Northwestern University, and the University of Florida have shed light on the enigmatic nature of these celestial "beasts." Black holes, among the universe's most mesmerizing phenomena, have a gravitational force so intense that
Uncovering Stellar Mysteries – Astrophysicists Observe Blue Supergiants in Detail
Stars serve as the fundamental building blocks of galaxies and, by extension, the entire observable universe. Among the diverse spectrum of stars, those with a mass exceeding 8 times that of the Sun are labeled as massive stars. Their potent radiation and formidable stellar winds exert a significant
Unlocking the Secrets of the Early Universe: Scientists Double Sensitivity of HERA Radio Telescope
Astronomers have taken a significant step forward in uncovering the mysteries of the cosmic dawn. A collection of 350 radio telescopes located in the Karoo desert of South Africa is rapidly advancing towards the detection of the "cosmic dawn" - the period following the Big Bang when stars first lit
Galactic Explosion Reveals New Details About the Universe
New research sheds light on the chemical formation of the universe. An international team of researchers stumbled upon an exploding supernova in a distant spiral galaxy, using data from the first year of interstellar observation by the James Webb Space Telescope. The recent research, published i
New Research Shows That Something Strange Is Going On in the Butterfly Nebula
Planetary nebulae are formed when red giant stars reach the end of their helium fuel supply and eject their outer layers, becoming hot and dense white dwarf stars about the size of Earth. The shed material, enriched with carbon, creates stunning patterns as it is slowly blown into the interstellar m
Unlocking the Mystery of the Stellar Initial Mass Function: A New Breakthrough Discovery
The fate of galaxies is determined by the initial mass distribution at the birth of a new population of stars in the diverse and vast Universe. This relationship is referred to as the Initial Mass Function (IMF). For over 50 years, astronomers have believed that the IMF is a universal relationship,
The Hunt for Cosmic Dawn: HERA Doubles Sensitivity to Unlock the Secrets of the Early Universe
The latest data from HERA improves the search for cosmic dawn radiation and tests theories of galaxy formation. An array of 350 radio telescopes located in the Karoo desert of South Africa is getting closer to detecting "cosmic dawn" - the time period following the Big Bang when stars first ignited
Astronomers Discover New Clues Regarding Stellar ‘Glitching’
Recent findings indicate that a significant number of stars exhibit irregularities in their cores. Scientists have discovered a method to examine the internal workings of some of the brightest stars in the sky. An international team of researchers, utilizing data from NASA's Kepler space telesco
A Doomed World: Astronomers Discover an Exoplanet Spiraling Toward Its Destruction
The impending demise of Kepler-1658b as it orbits its aging star offers an opportunity for scientists to gain insight into the fate of other planets and their evolving solar systems. Astronomers have made a groundbreaking discovery of an exoplanet whose orbit is deteriorating as it orbits an agin
Defying Conventional Theories: How Does Radiation Travel Through Dense Plasma?
First-of-its-kind experimental evidence contradicts traditional theories about the emission and absorption of radiation by plasmas. While solids, liquids, and gases are familiar states of matter, there is a fourth state called plasmas which is the most common form of matter in the universe. It can
ALMA Views a Newborn Star Enshrouded in Dust
This newly released ALMA image shows a newborn star enshrouded in dust. This intriguing image may look like a collection of colored blobs, but it is actually a high-resolution snapshot of a newborn star enshrouded in dust. Located 1300 light-years away in the Orion Nebula, the star, named HH 212,
Hubble Detects Plasma Ejections Shooting From V Hydrae
Hubble observations have revealed a string of super-hot blobs, each with a temperature of more than 17,000 degrees Fahrenheit, being ejected from a dying star. Great balls of fire! NASA's Hubble Space Telescope has detected superhot blobs of gas, each twice as massive as the planet Mars, being ej
Observations of Sun-Like Stars Improves Our Understanding of Magnetic Dynamos
The spots on the surface on the Sun come and go with an 11-year periodicity known as the solar cycle. The solar cycle is driven by the solar dynamo, which is an interplay between magnetic fields, convection and rotation. However, our understanding of the physics underlying the solar dynamo is far from complete.
Astronomers Make Shocking Discovery About Stars Around the Milky Way
An international team of astronomers has made a surprising discovery about the birthplace of groups of stars located in the halo of our Milky Way galaxy. They reveal compelling evidence that some of these halo structures actually originate from the Milky Way’s disk itself, but were kicked out.
Astronomers Discover Density Waves in Protoplanetary Disk Surrounding Elias 2-27
Astronomers have discovered a striking spiral-arm structure in the disc of gas and dust around the young star Elias 2-27. The structure is made up of the matter near the midplane of the disc – the region in which new planets can be born. This means: the spirals are either a result of the presence of
ALMA Reveals the First Hot Core Found Outside the Milky Way
Using the Atacama Large Millimeter/submillimeter Array, a team of astronomers reveal the first hot core to be found outside the Milky Way. A hot and dense mass of complex molecules, cocooning a newborn star, has been discovered by a Japanese team of astronomers using ALMA. This unique hot molecul
Ancient Radio Signals Reveal What the First Stars Were Like
For the first time, astronomers have detected a signal from stars emerging in the early universe. Using a radio antenna not much larger than a refrigerator, the researchers discovered that ancient suns were active within 180 million years of the Big Bang.
ESO Image of the Week - Spirals with a Tale to Tell
This newly released image shows a protoplanetary disc surrounding the young star Elias 2-27. This beautiful image, captured with the Atacama Large Millimeter/submillimeter Array (ALMA) features a protoplanetary disc surrounding the young star Elias 2-27, some 450 light years away. ALMA has discov
Carbon-Rich Stardust Grains Unlock Astrophysical Mysteries
Dust is everywhere--not just in your attic or under your bed, but also in outer space. To astronomers, dust can be a nuisance by blocking the light of distant stars, or it can be a tool to study the history of our universe, galaxy, and Solar System.
Astronomers Measure the Inner Structure of Distant Stars
An international team of astronomers, under the leadership of Earl Bellinger and Saskia Hekker of the Max Planck Institute for Solar System Research in Göttingen, has, for the first time, determined the deep inner structure of two stars based on their oscillations.
“One of a Kind” Massive Triple Star System Detected
Compact, massive triple star system detected by University of Copenhagen researchers. Earlier this year, researchers revealed the discovery of an extraordinarily compact "one-of-a-kind" system of three stars. A partnership between two young researchers at the Niels Bohr Institute at the University
