This Lunar Eclipse Composite is so Stunning, We Can Not Believe It’s Real

A composite image from the 8 November 2022 total lunar eclipse showing the moon in various stages throughout the night. (Andrew McCarthy)We have seen some great pictures from the total lunar eclipse recently. But this one might top them all.Astrophotographer Andrew McCarthy produced this incredible composite photo, showing the Moon in different eclipse phases throughout...

Heaviest Element Yet Detected in an Exoplanet Atmosphere

This artist’s impression shows an ultra-hot exoplanet, a planet beyond our Solar System, as it is about to transit in front of its host star. When the light from the star passes through the planet’s atmosphere, it is filtered by the chemical elements and molecules in the gaseous layer. With sensitive instruments, the signatures...

Researchers Reveal Further Evidence of Salted Water on Mars

Mars Orbiter Laser Altimeter (MOLA) topographic map of the investigated area at Ultimi Scopuli. Dotted lines are MARSIS observations. The blue region indicates the geographic location of the main bright area. The observations in the light-gray shadowed area have not been used for data inversion, as they cross high and low basal reflectivity areas...

A Current Potentially Dangerous Asteroid Found

Three near-Earth asteroids -- one potentially hazardous -- were found using a high-tech instrument at the Cerro Tololo Inter-American Observatory in Chile.On Monday, an international group of astronomers reported the finding of a giant asteroid whose orbit crosses that of Earth, developing a slight possibility far in the future of a disastrous accident.The 1.5-kilometre-...

A Supercomputer Simulations Gives us a New Look at The Formation of the Moon

An image from the super computer simulation of the creation of the Moon. Credit: Durham UniversityResearchers from Durham University's Institute for Computational Cosmology used the most precise supercomputer simulations ever, revealing an alternative for how the Moon formed 4.5 billion years ago. It showed that a colossal impact between Earth and a Mars-sized body...

NASA’s Juno Gets the Highest-Resolution Close-Up of Jupiter’s Moon Europa

Surface features of Jupiter’s icy moon Europa are revealed in an image obtained by Juno’s Stellar Reference Unit (SRU) during the spacecraft’s Sept. 29, 2022, flyby.
