In this photo made available by NASA, the space shuttle Challenger launches the Earth Radiation Budget Satellite in 1984. On Friday, Jan. 6, 2023, the U.S. space agency said the 38-year-old NASA satellite is about to fall from the sky, but the chance of wreckage falling on anybody is “very low.” It's expected to...
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...
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.

(Dorit Bar-Zakay/Moment/Getty Images)Scientists think that old rock tools found in Brazil are the work of capuchin monkeys, not early human beings, the art and design website Artnet reported, mentioning an academic article."We are confident that the very early archeological websites from Brazil might not be human-derived but might come from capuchin apes," wrote archaeologist...
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...

The Marine Optical Buoy (MOBY) is an ocean-color sensor that serves as a primary reference instrument for satellite measurements of the color of the ocean. Single-cell plants called phytoplankton contain chlorophyll that reflects the green in sunlight, which gives the ocean color. Researchers can study these measurements to better understand the planet's climate. MOBY...
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...
Two projections of the molecular structure of 1. Credit: Molecules (2022). DOI: 10.3390/molecules27196205RUDN University chemists have produced new copper-containing metallasilsesquioxane frameworks. A few of them have proven to be effective catalysts for the oxidation of hydrocarbons. The results are published in Molecules.What are SilsesquioxanesSilsesquioxanes are a enormous team of organosilicon compounds. They are formed of a...
JWST's new image of NGC 7469. (ESA/Webb, NASA & CSA, L. Armus, A. S. Evans)The perfect galaxy photoThe James Webb Space Telescope simply gave a spiral galaxy 230 million light-years away a recent sparkling glamor shot excellent sufficient for the Christmas tree.While the galaxy has the instead un-attractive name of NGC 7469, it has been...
