Amateur astronomer captured a Doppler image of the sun on Nov. 11, showing a magnetic filament lifting off and moving toward Earth, indicated by a blueshift. Using an H-alpha filter, he observed the filament’s velocity on the solar disk, with much of the material angled toward…
The #JWST detected potential signs of a sulfurous atmosphere on the exoplanet L98-59d, orbiting a red dwarf 35 light-years away. Researchers suggest intense volcanism, similar to Jupiter's moon Io, might sustain this atmosphere, despite the planet’s close proximity to its star.…
Yes. Gluons (which mediate the strong nuclear force) are also massless, though they are always confined within larger particles. Hypothetical gravitons, if they exist, would be massless as well, acting as carriers of gravity.
Vaidya radiation describes a type of radiation emitted by a dynamic black hole that changes mass over time. Unlike the Schwarzschild solution, which assumes a static, unchanging black hole, the Vaidya solution accommodates a black hole that absorbs or emits energy, typically in…
Researchers have shown that black holes emit "Vaidya Radiation" to stay stable while absorbing matter, allowing Hawking radiation to escape. This radiation, caused by tidal heating from infalling matter, prevents the black hole's event horizon from stretching, letting it behave…
China has revealed a new design for its Long March 9 rocket, closely resembling SpaceX's Starship, with a fully reusable configuration planned. The Long March 9, expected to launch around 2033, will be powered by 30 YF-215 engines and can carry 150 tons to low Earth orbit. Like…

Since quasars vary in brightness, all images should display similar brightness changes, though each may have a slight time delay due to differing travel paths. Monitoring these fluctuations across all images confirms they are from the same source if the variations match up with…
This new study reports J1721+8842 as the first known "Einstein zig-zag lens," a unique gravitational lensing system where two galaxies create six distinct images of a background quasar. One galaxy at redshift z1 = 0.184 and another at z2 = 1.885 cause the quasar’s light to…
Happy Halloween. Yesterday, #asteroid 2024 UG9 buzzed Earth just 2476 km above the Indian Ocean. 6 hours later, it passed 18279 km above the Moon. It is the size of a giant pumpkin 🎃.
A 3D map of the Milky Way’s Local Hot Bubble (LHB) created from eROSITA data reveals a low-density region around the solar system, heated by ancient supernovas. The bubble shows temperature gradients and an interstellar “tunnel” toward Centaurus, likely formed by young stars’…
Génial !
Scientists have achieved a major advancement in quantum teleportation, transferring quantum states (not particles) between entangled particles over greater distances with increased precision. This method could transform secure communication and quantum computing by instantly…
.@NASAJuno spacecraft has captured breathtaking new images of Jupiter during its recent flyby, revealing intricate details of the planet's dynamic atmosphere. These images highlight the colorful, swirling cloud formations and massive cyclonic storms in Jupiter's northern…

A supermassive black hole located 12.1 billion light-years from Earth is consuming matter at a phenomenal rate — over 40 times the theoretical limit! This discovery could help explain how supermassive black holes grew so quickly in the early Universe: s.si.edu/lid568 ⚫
In 2009, astronomers observed a massive star, N6946-BH1, about 25 times the mass of the Sun, that appeared to increase in brightness, a sign typically associated with a supernova, only to fade without exploding. Theories initially suggested that this star could have collapsed…
The LHC at @CERN has started a 17-day heavy-ion run, colliding lead ions to study quark-gluon plasma, a state of matter from the early universe. Upgrades aim to achieve 30% more collisions than last year. Experiments like ALICE, CMS, ATLAS, and LHCb have enhanced…

This new study tests mimetic gravity theory against black hole observations from the Event Horizon Telescope @ehtelescope, specifically the supermassive black holes in M87 and Sgr A*. Mimetic gravity proposes black hole and naked singularity solutions, but the study finds that…
