Astronomers detect the closest example yet of a black hole devouring a star
Once every 10,000 years or so, the center of a galaxy lights up as its supermassive black hole rips apart a passing star. This “tidal disruption event” happens in a literal flash, as the central black hole pulls in stellar material and blasts out huge amounts of radiation in the process.
Next-Generation Aramid Fiber with Electrical Conductivity
Dr. Dae-Yoon Kim and his research team at the Functional Composite Materials Research Center within the KIST Jeonbuk Institute of Advanced Composite Materials announced that they have applied carbon nanotubes to aramid fibers to develop a new kind of composite fiber.
New study about the ‘tsunami’ in Venus’s clouds
A group of scientists from the University of Seville, in collaboration with experts from the University of the Basque Country, has led the first detailed study of the evolution of the discontinuity of Venus’s clouds, a gigantic atmosphere wave with the appearance of a “tsunami” that is propagated in the planet’s deepest clouds and which, it is believed, may be playing a very significant role in the acceleration of Venus’s fast-moving atmosphere.
Read the invisible pores in CT images
The KICT announced that the research team led by Dr. Hyusoung Shin has developed a new method, named the statistical phase fraction (SPF) method, to estimate porosity and to evaluate homogeneity of porous materials dominated by sub-resolution pores via CT image analysis.
Scientists call for global push to eliminate space junk
Scientists have called for a legally-binding treaty to ensure Earth’s orbit isn’t irreparably harmed by the future expansion of the global space industry.
Solid‒gas carbonate formation during dust events on Mars
A joint research team led by Dr. Xiaohui Fu and Dr. Zhongchen Wu from Shandong University, China, proposed a new carbonate formation mechanism in Martian dust activities based on simulation experimental studies.
‘Engine’ of luminous merging galaxies pinpointed for the first time
Roughly 500 million light-years away, near the constellation Delphinus, two galaxies are colliding.
Cosmological enigma of Milky Way’s satellite galaxies solved
Astronomers say they have solved an outstanding problem that challenged our understanding of how the Universe evolved – the spatial distribution of faint satellite galaxies orbiting the Milky Way.
Planetary science: Mars megatsunami may have been caused by Chicxulub-like asteroid impact
A Martian megatsunami may have been caused by an asteroid collision similar to the Chicxulub impact – which contributed to the mass extinction of all non-avian dinosaurs on Earth 66 million years ago – in a shallow ocean region, according to a study published in Scientific Reports.
Discovery could dramatically narrow search for space creatures
An Earth-like planet orbiting an M dwarf — the most common type of star in the universe — appears to have no atmosphere at all. This discovery could cause a major shift in the search for life on other planets.
Affordable housing in outer space: Scientists develop cosmic concrete from space dust and astronaut blood
Transporting a single brick to Mars can cost more than a million British pounds – making the future construction of a Martian colony seem prohibitively expensive.
Titan-in-a-glass experiments hint at mineral makeup of Saturn moon
Titan, Saturn’s largest moon, has a dense atmosphere and weather cycles like Earth. Now, researchers have recreated the moon’s conditions in small glass cylinders, revealing properties of two molecules believed to exist as minerals on Titan. They will present their results at ACS Fall 2021.
When space travel is a blur
Working with the Canadian Space Agency and NASA, two Quebec-based researchers are keeping an eye on astronauts’ ocular health.
