In the (convection) zone: Astronomers eavesdrop on stars’ innate “twinkle”
"Convection within stars is similar to the process that fuels thunderstorms." Visualization of "Twinkle, Twinkle, Little Star" played through three sizes of massive stars. Credit: Northwestern University. Science 101 tells us that t.....»»
Exoplanets could be hiding their atmospheres
Most of the exoplanets we've discovered orbit red dwarf stars. This isn't because red dwarfs are somehow special, simply that they are common. About 75% of the stars in the Milky Way are red dwarfs, so you would expect red dwarf planets to be the mos.....»»
Citizen science collaboration yields precise data on exoplanet WASP-77 A b
A planet swings in front of its star, dimming the starlight we see. Events like these, called transits, provide us with bounties of information about exoplanets—planets around stars other than the sun. But predicting when these special events occur.....»»

X-Ray Imaging and Spectroscopy Mission unveils black hole and supernova remnant surroundings
The X-Ray Imaging and Spectroscopy Mission (XRISM) has revealed the structure, motion and temperature of the material around a supermassive black hole and in a supernova remnant in unprecedented detail. Astronomers presented the first scientific resu.....»»
Scientists scan TRAPPIST-1 for technosignatures
If you are going to look for intelligent life beyond Earth, there are few better candidates than the TRAPPIST-1 star system. It isn't a perfect choice. Red dwarf stars like TRAPPIST-1 are notorious for emitting flares and hard X-rays in their youth,.....»»
NASA"s Chandra finds galaxy cluster that crosses the streams
Astronomers using NASA's Chandra X-ray Observatory have found a galaxy cluster has two streams of superheated gas crossing one another. This result shows that crossing the streams may lead to the creation of new structure......»»
Astronomers just detected the biggest black hole jets ever seen—and named them Porphyrion
The largest known black hole jets, 23 million light years across, have been discovered in the distant universe. This pair of particle beams launched by a supermassive black hole is over a hundred times larger than our galaxy, the Milky Way......»»

Observations provide crucial insights into the nature of a white dwarf–brown dwarf binary
Using the Hubble Space Telescope (HST), astronomers have performed spectrophotometric observations of an eclipsing white dwarf–brown dwarf binary known as WD1032+011. Results of their observational campaign, published September 10 on the preprint s.....»»
Astronomers detect hundreds of supernova remnants using novel method
Using a new method exploiting the capabilities of the Multi Unit Spectroscopic Explorer (MUSE), astronomers have detected 307 new supernova remnants, including seven rare oxygen-rich ones. The finding was presented in a research paper published Septe.....»»

Astronomers discover new feature in exoplanet distribution that"s between the Neptunian Desert and Savanna
Astronomers have uncovered the "Neptunian Ridge," a newly identified feature in the distribution of exoplanets. This discovery, led by an international team including members of the University of Geneva, The NCCR PlanetS and the Centro de Astrobiolog.....»»
Comprehensive model uses airborne LiDAR data to predict walking travel times with unprecedented accuracy
You're a hotshot working to contain a wildfire. The conflagration jumps the fire line, forcing your crew to flee using pre-determined escape routes. At the start of the day, the crew boss estimated how long it should take to get to the safety zone. W.....»»
Astronomers detect black hole "starving" its host galaxy to death
Astronomers have used the NASA/ESA James Webb Space Telescope to confirm that supermassive black holes can starve their host galaxies of the fuel they need to form new stars. The results are reported in the journal Nature Astronomy......»»
Astronomers discover new planet in Great Bear constellation
Astronomers from the Nicolaus Copernicus University in Torun have discovered a new planet in the constellation of the Great Bear. It has a mass as much as 11 times that of Jupiter, orbits its star in 14 years and has a temperature of no more than min.....»»
Huge gamma-ray burst collection "rivals 250-year-old Messier catalog," say astronomers

Experimental data help unravel the mystery surrounding the creation of heavy elements in stars
How are stars born, and how do they die? How do they produce the energy that keeps them burning for billions of years? How do they create the elements we observe today? Definitive answers to these questions continue to elude scientists in their quest.....»»
Webb peers into the Extreme Outer Galaxy
Astronomers have directed NASA's James Webb Space Telescope to examine the outskirts of our Milky Way galaxy. Scientists call this region the Extreme Outer Galaxy due to its location more than 58,000 light-years away from the Galactic Center. (For co.....»»
