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...
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-...
The giant El Gordo galaxy cluster has been used to spot a tiny galaxy beyond it.

Credit: NASA, Jim Watson / Getty ImagesAn asteroid notoriously erased the dinosaurs about 66 million years ago. Could one more one do the very same to us? That question has led NASA researchers and designers to create the DART program, whose duty was to redirect the motion of an asteroid. The mission was a...
An artist's impression of the "burping" black hole. Credit: DESY / Science Communication Lab 3 years earlier, in October 2018, astronomers saw a black hole consuming and ripping one star apart in a galaxy 665 million light yrs away from Earth.Currently, just recently, the same astronomers observed the same black hole lighting the sky, despite the...
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...

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...
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. Credits: NASA/JPL-Caltech/SwRIThe highest-resolution photo NASA's Juno objective has ever taken of a specific portion of Jupiter's moon Europa shows a detailed view of a puzzling region of the...
