Flashes on the Sun Could Aid Researchers in Predicting Solar Flares

Two images of a solar active region (NOAA AR 2109) taken by SDO/AIA show extreme-ultraviolet light produced by million-degree-hot coronal gas (top images) on the day before the region flared (left) and the day before it stayed quiet and did not flare (right). The changes in brightness (bottom images) at these two times show...

New Outcomes Reveal Surprising Behavior of Minerals Deep in the Earth

Boudinage in brecciated dolostone rocks of the Panamint Range (Wildrose Area, Death Valley National Park). New research shows that periclase is stronger than bridgmanite in the earth's lower mantle, analogous to boudins developing in rigid ("stronger") rocks among less competent ("weaker") rocks.

Doomed Pair of Supermassive Black Holes the Closest to Collision Ever Seen

This artist's conception shows a late-stage galaxy merger and its two newly-discovered central black holes. The binary black holes are the closest together ever observed in multiple wavelengths. Credit: ALMA (ESO/NAOJ/NRAO); M. Weiss, NRAO/AUI/NSFAstronomers have found two ghostly Goliaths en route to a catastrophic meeting. The newly found pair of supermassive black holes are...

New Study Reveals a Wide Diversity of Galaxies in the Early Universe

Credit: Unsplash/CC0 Public DomainNew information from the James Webb Space Telescope (JWST) have revealed that the structures of galaxies in the early universe were much more diverse and also mature than previously known. Researchers recently compared photos of hundreds of galaxies taken by JWST for the Cosmic Evolution Early Release Science (CEERS) Survey with...

Massive Volcanic Outburst Spotted on Jupiter’s Hellish Moon Io

An infrared image of Io snapped by Juno in July 2022. (NASA/JPL-Caltech/SwRI/ASI/INAF/JIRAM)The most powerful volcanic eruptions in the Solar System occur not on Earth, however on Io, a sulfurous moon orbiting the planet Jupiter.And currently, researchers from the Planetary Science Institute (PSI) in the United States have noticed a current outburst that's been surprisingly productive,...

Powerful Solar Flare Bursts From Sun

NASA’s Solar Dynamics Observatory captured this image of a solar flare – as seen in the bright flash on the left picture– on Jan. 5, 2023. The image shows a subset of extreme ultraviolet light that highlights the extremely hot material in flares and which is colorized in AIA 171 orange. Credit: NASA/SDOThe sun...

Giant Mantle Plume Reveals Mars is More Active Than Previously Thought

HD 213258 is a Rapidly Oscillating, Strongly Magnetic Ap Star; a Study Discovers

Portion of the spectrum of HD 213258. Credit: Mathys et al, 2022Utilizing the Canada-France-Hawaii Telescope (CFHT), astronomers have observed a chemically peculiar star called as HD 213258. In the outcome, they found that HD 213258 is a quickly oscillating, strongly magnetic Ap star. The finding is reported in a paper released on December 24...
