Astronomers want your help hunting for asteroids
Anyone can become an asteroid hunter thanks to a new program launched by astronomers at the University of Arizona Lunar and Planetary Laboratory. As part of the Catalina Sky Survey, the scientists created an online portal that opens their mission—t.....»»
JWST data suggest exoplanet K2-18b may have molten surface rather than a watery ocean
A multi-institutional team of astronomers, Earth scientists and planetary physicists has found evidence, via data from the James Webb Space Telescope (JWST), that some hycean exoplanets may have molten surfaces rather than watery oceans. In their stu.....»»
Researchers discover cosmic dust storms from Type 1a supernova
Cosmic dust—like dust on Earth—comprises groupings of molecules that have condensed and stuck together in a grain. But the exact nature of dust creation in the universe has long been a mystery. Now, however, an international team of astronomers f.....»»
NASA"s Roman telescope to use rare events to calculate expansion rate of universe
Astronomers investigating one of the most pressing mysteries of the cosmos—the rate at which the universe is expanding—are readying themselves to study this puzzle in a new way using NASA's Nancy Grace Roman Space Telescope. Once it launches by M.....»»
Astronomers measure the mass of the Milky Way by calculating how hard it is to escape
If you want to determine your mass, it's pretty easy. Just step on a scale and look at the number it gives you. That number tells you the gravitational pull of Earth upon you, so if you feel the number is too high, take comfort that Earth just finds.....»»
Finding the best predictor for a galaxy"s metallic content
A team of astronomers has found that the total mass of stars in a galaxy is not a good predictor of the galaxy's abundance of heavier elements, a surprising result according to previous studies. Instead, the gravitational potential of a galaxy is a m.....»»
New findings from JWST: How black holes switched from creating to quenching stars
Astronomers have long sought to understand the early universe, and thanks to the James Webb Space Telescope (JWST), a critical piece of the puzzle has emerged. The telescope's infrared detecting "eyes" have spotted an array of small, red dots, identi.....»»
Small satellite may shape centaur rings
The unique two thin rings around the Centaur Chariklo could be shaped by an even smaller satellite. Chariklo is a Centaur, which are small bodies similar to asteroids in size but to comets in composition, that revolve around the sun in the outer sola.....»»
Extreme eruption on young sun-like star signals savage environment for developing exoplanets
Astronomers have detected an extreme eruption from a young star that became more than a hundred times brighter in only a few hours. This discovery offers new insight into how young sun-like stars behave early in their lives, and their impact on the d.....»»
India"s tigers climb high as climate, human pressure rises
Tigers in India have been photographed in high-altitude mountains rarely seen before, with experts suggesting relentless human pressure and a heating climate are driving them from traditional hunting grounds......»»
A super-Earth (and possible Earth-sized) exoplanet found in the habitable zone
Astronomers have found a new Super-Earth orbiting an M-dwarf (red dwarf) star about 137 light-years away. The planet is named TOI-715b, and it's about 1.55 Earth's radius and is inside the star's habitable zone. There's also another planetary candida.....»»
Astronomers inspect a peculiar pulsating variable white dwarf
Astronomers have conducted spectroscopic and photometric observations of a peculiar pulsating variable white dwarf known as TMTS J17184064+2524314. Results of the observational campaign, published January 26 on the preprint server arXiv, provide esse.....»»
Astronomers discover a super-Earth located in the habitable zone
Astronomers have discovered a type of exoplanet called a "super-Earth" located in the habitable zone of its small star - and it's right in our cosmic backyard......»»
Dark matter might help explain how supermassive black holes can merge
Although the exact nature of dark matter continues to elude astronomers, we have gained some understanding of its general physical properties. We know how it clusters around galaxies, how it makes up much of the matter in the universe, and even how i.....»»
Team of astronomers discovers galaxy that shouldn"t exist
A team of astronomers, led by Arizona State University Assistant Research Scientist Tim Carleton, has discovered a dwarf galaxy that appeared in James Webb Space Telescope imaging that wasn't the primary observation target......»»
Best Galaxy S24 Alternatives (February, 2024)
Samsung’s new Galaxy S24, Galaxy S24+, and Galaxy S24 Ultra are intriguing options if you’re hunting for a new phone. That being said, they might be too expensive for your budget or perhaps you just want something similar from another OEM.....»»
Astronomers in Chile to scour universe with car-sized mega camera
Surrounded by the desert mountains and clear blue sky of northern Chile, astronomers from the Vera C. Rubin Observatory hope to revolutionize the study of the universe by affixing the world's largest-ever digital camera to a telescope......»»
Researchers investigate the nature of a recently discovered very-high-energy source
Using XMM-Newton, Chandra and NuSTAR space telescopes, an international team of astronomers has explored the nature of a recently-detected very-high-energy source designated 2FHL J1745.1–3035. Results of the study, published Jan. 24 on the pre-prin.....»»
New Wolf in the pack: Astronomers discover an ultra-short-period super-Earth
Using NASA's Transiting Exoplanet Survey Satellite (TESS), an international team of astronomers has discovered a new ultra-short-period exoplanet. The newfound alien world, designated Wolf 327 b, is slightly larger and about 2.5 times more massive th.....»»
