Credit: Canva The model represents a shortage of planets with masses between super-Earths and mini-Neptunes A new model that represents the interaction of forces acting upon newborn planets can clarify two puzzling observations that have repeatedly turned up among the over 3,800 planetary systems cataloged to date. One puzzle called the "radius valley" refers to the rarity...
The giant El Gordo galaxy cluster has been used to spot a tiny galaxy beyond it. Credit: NASA. The James Webb Space Telescope has glimpsed the tiniest galaxy outside our regional world-- and it is a thousand times much less huge than the Milky Way. The James Webb Space Telescope (JWST) has found the tiniest galaxy...
Illustration of a “super Neptune,” TOI-674 b, with an atmosphere that, according to a recent study, includes water vapor. Credit: NASA/JPL-Caltech Water vapor in the atmosphere of planet TOI-674 b This newly found planet, a bit larger than Neptune and orbiting a red-dwarf star roughly 150 light-years away. This size places it in an exclusive club:...
Titan Galaxy Cluster Magnifies the Light from a Distant Supernova and Splits It into Multiple Images Individuals over the centuries have not been reluctant to make forecasts concerning the future. However, a few of them should have maintained their projections to themselves. The head of state of the Michigan Savings Bank, as an example, forecasted...
Vega is the fifth brightest star, excluding the sun, that can be seen from Earth. (Image credit: NASA/JPL-Caltech) A possible searing-hot planet was spotted by astronomers, orbiting Vega, one of the brightest and most known stars in the sky. Approximately the size of Neptune, the candidate alien planet lies very close to Vega, taking 2.5 Earth...
In the realm of galaxies, our minds often conjure images of luminous spiral formations teeming with stars and cosmic gases. However, a distinct category known as low-surface-brightness galaxies challenges this conventional perception. These galaxies, characterized by sparse stars and unconventional appearances, typically harbor more dark matter and predominantly consist of gas, with few discernible...
Using a PEM electrolyzer, the researchers create hydrogen in the laboratory. Credit: Eduardo Gracia Researchers at Umeå University have made a breakthrough that could make hydrogen, a carbon dioxide (CO2)-free fuel, more affordable. The team has created a new method to increase the production of hydrogen gas from water and electricity, a process critical to...
his is an artist's impression of two neutron stars colliding. The smashup between two dense stellar remnants unleashes the energy of 1,000 standard stellar nova explosions. In the aftermath of the collision a blowtorch jet of radiation is ejected at nearly the speed of light. The jet is directed along a narrow beam confined...
