In a recent study published in National Science Review, a team of researchers led by the China University of Geosciences discuss direct evidence of an ancient ocean and its shoreline that existed in the northern hemisphere of Mars during the Hesperian Period, or more than 3 billion years ago. This finding is based on data collected by the China National ...

Launched on April 14, 2023, the European Space Agency’s (ESA) Jupiter Icy Moons Explorer (Juice; formerly known as JUICE) spacecraft has finally completed the unfurling of its solar panel arrays and plethora of booms, probes, and antennae while en route to the solar system’s largest planet. However, Juice’s first six weeks in space haven’t been so smooth, as its Radar ...

The European Space Agency’s latest third generation Meteosat-I 1 weather satellite shows its stuff, with more to come. You’ve never seen the Earth and its complex weather systems like this. The European Space Agency (ESA) recently unveiled views from their latest weather satellite in geostationary (GEO) orbit, Meteosat Third Generation Imager-1 (MTG-I 1). MTG-I 1 promises to revolutionize crucial full-disk ...

New images from NASA’s Lunar Reconnaissance Orbiter (LRO) appear to show the crash site where the Japanese Hakuto-R Mission 1 lunar lander impacted the surface of the Moon a month ago. The refrigerator-sized HAKUTO-R was built by the startup company iSpace and was launched in December 2022 with the goal of becoming the first commercial lunar lander to touch down ...

Most black holes are stellar mass black holes. They’re created when a star several times more massive than our Sun reaches the end and collapses in on itself. There are also supermassive black holes (SMBH,) the behemoths at the center of galaxies that can boast billions of times more mass than the Sun. But where are the intermediate-mass black holes? ...

We’ve previously reported on some of their successes. Now it’s time for the next round ...

NOIRLab Photo Release: “Radiant Protostars and Shadowy Clouds Clash in Stellar Nursery” noirlab2313 (2023) There are some astronomical images that capture rapturous beauty, with their brilliant colors and interplay of shadow and light. A beautiful image can be enough to stir the soul, but in astronomy they often also have a story to tell. An example of this can be ...

We have no idea what it dark energy is, so how are we pretty sure it exists? I’ve talked about how astronomers know that dark matter exists. Even though they can’t see it, they detect it through the effect its gravity has on light. Dark matter accounts for 27% of the Universe, dark energy accounts for 68% of the Universe. ...

The James Webb Space Telescope (JWST) was designed to probe the mysteries of the Universe, not the least of which is what the first galaxies looked like. These galaxies formed during the Epoch of Reionization (aka. “Cosmic Dawn”), which lasted from about 100 to 500 million years after the Big Bang. By observing these galaxies and comparing them to ones ...

Earth experiences seasonal changes because of how its axis is tilted (23.43° relative to the Sun’s equator), causing one hemisphere to always be tilted towards the Sun (and the other away) for different parts of the year. However, because of gravitational interactions between the Earth, Sun, Moon, and other planets of the Solar System, Earth has experienced changes in its ...
