James Webb Telescope Uncovers Mysterious High-Energy Radiation in Star Birth Regions

Astronomers using the James Webb Space Telescope discovered unexpected high-energy ultraviolet radiation around five protostars in the Ophiuchus star-forming region, challenging previous assumptions that young stars do not produce such radiation. The findings suggest the radiation is likely generated internally, possibly from shocks during material infall or jets from the protostars, prompting a reevaluation of star formation models.

"Sneezing Baby Stars: Insights into Cosmic Development"

Baby stars, or protostars, have been observed "sneezing" by expelling gas, dust, and magnetic fields, which is a vital part of their development and can provide insights into their evolution and potential planet formation. Researchers from Kyushu University used the ALMA telescope to study these sneezes and discovered spike-like structures extending from protostellar disks, indicating the expulsion of magnetic flux. Understanding these processes can enhance our knowledge of how stars and planets are formed.

"Webb Telescope Discovers Ethanol and Burning Acid in Deep Space"

NASA's James Webb Space Telescope has made a new discovery, detecting key ingredients for making potentially habitable worlds when observing protostars, including ethanol, acetic acid, methane, formaldehyde, and sulfur dioxide. These findings contribute to the understanding of the origin of complex organic molecules in space and suggest that solid-phase chemical reactions on the surfaces of cold dust grains can build complex kinds of molecules, which can become part of comets, asteroids, and new planetary systems as the protostellar system evolves.

"Discovery of 'Old Smokers' and Erupting Protostars Unveils New Stellar Types in the Milky Way"

Astronomers have discovered new types of stars in the Milky Way, including "old smokers" and erupting protostars, through a decade-long infrared survey. These findings challenge existing theories on stellar life cycles and element distribution in space. The discovery of elderly giant stars that periodically emit smoke and undergo outbursts provides new insights into stellar evolution and the formation of new solar systems. This groundbreaking research was conducted using advanced telescopes and could potentially change our understanding of how elements are distributed across space.

"Unveiling Ancient 'Old Smokers' and 'Screaming' Newborn Stars in the Milky Way"

Astronomers have discovered a new category of ancient giant red stars, dubbed "old smokers," as well as violently erupting newborn protostars in the Milky Way's heart through a 10-year survey with the VISTA telescope. The team found 32 erupting protostars and 21 "old smokers," which are red stars that suddenly emit clouds of smoke after sitting quietly for decades. These discoveries could provide insights into the distribution of heavy elements in the cosmos and the formation of stars and planets.

"Astronomers Uncover Ancient Smoking Stars in Milky Way's Core"

Astronomers have discovered a group of giant elderly stars, dubbed "old smokers," at the center of the Milky Way emitting solar system-sized clouds of dust and gas. These stars, previously faded to near invisibility, suddenly release vast clouds of smoke, a phenomenon attributed to convection currents and instabilities within the stars. The discovery, made during a 10-year survey of almost a billion stars in infrared light, has wider implications for the spread of heavy elements in the nuclear disc and metal-rich regions of other galaxies.

"Discovery of 'Old Smokers': Ancient Giant Stars Unveiled in the Milky Way"

Astronomers have discovered hidden stars, including a new type of elderly giant nicknamed "old smokers," at the heart of the Milky Way galaxy, using infrared light to see through the dust and gas that obscures them in visible light. The team also found rarely-seen newborn stars, known as protostars, undergoing extreme outbursts, shedding light on the formation of new solar systems. Additionally, they detected a new type of red giant star that remains dim and red for years before puffing out clouds of smoke, challenging previous understanding of stellar matter ejection and the distribution of heavy elements in the galaxy.

"Stunning Image: James Webb Telescope Reveals Super-Hot Jet 1000 Light-Years Away"

The James Webb Space Telescope has captured a stunning image of Herbig Haro object number 797, a luminous region surrounding newborn stars located about 1,000 light-years from Earth. The image reveals the previously unknown source of the spectacular jets as two stars, along with other outflows from a protostar. The Webb telescope's infrared capabilities allow it to visualize the structure of the outflows by collecting the infrared light emitted by molecules excited by the turbulent conditions.

"Stunning Image: James Webb Telescope Reveals Birth of a Star"

The James Webb Space Telescope has captured a stunning image of a Herbig-Haro object, showcasing the dramatic outflows from a young star. These objects are formed when stellar winds shoot off in opposite directions from newborn stars, colliding with nearby gas and dust. The image, taken using Webb's Near-Infrared Camera, reveals intricate details of the object and shows that there are actually two sets of outflows coming from a pair of stars at the center. Infrared imaging is particularly useful for studying newborn stars and their outflows, as it can penetrate the obscuring gas and dust.
