Hubble Space Telescope Detects Protective Shield Defending a Pair of Dwarf Galaxies

Hubble Space Telescope Detects Protective Shield Defending a Pair of Dwarf Galaxies

Scientists have used spectroscopic observations of ultraviolet light from quasars to detect and map the Magellanic Corona, a diffuse halo of hot, supercharged gas surrounding the Small and Large Magellanic Clouds. Shown in purple, the corona stretches more than 100,000 light-years from the main mass of stars, gas, and dust that make up the Magellanic …

How a Chinese fish fossil discovery rewrites the history of life's evolution

How a Chinese fish fossil discovery rewrites the history of life’s evolution

Paleontologists are having a field day over a recently discovered trove of fish fossils that could reset our understanding of human evolution. The finds not only include the world’s oldest teeth, but also strengthen the evidence for the emergence of jaws and limbs. Essentially, these discoveries could push back our understanding of humans’ early animal …

A Planet-Sized Heatwave Has Been Found in Jupiter's Atmosphere

A Planet-Sized Heatwave Has Been Found in Jupiter’s Atmosphere

A heatwave the size of 10 Earths has been discovered rippling through Jupiter’s atmosphere. It was 130,000 kilometers (around 81,000 miles) across, and a scorching 700 degrees Celsius (1,292 degrees Fahrenheit), traveling at speeds up to 2,400 meters per second away from the Jovian north pole. And this, scientists say, could resolve one of the …

NASA’s Juno Spacecraft Captures Closest View of Jupiter’s Icy Moon Europa in 22 Years

On September 29, 2022, NASA’s Juno spacecraft captured the complex, ice-covered surface of Jupiter’s moon Europa during a close flyby. Credit: NASA/JPL-Caltech/SWRI/MSSS Observations from the Juno spacecraft’s close pass of the icy moon provided the first close-up in over two decades of this ocean world, resulting in remarkable imagery and unique science. Earth has now …

Potential first traces of the universe’s earliest stars

Potential first traces of the universe’s earliest stars

Astronomers may have discovered the ancient chemical remains of the first stars to light up the Universe. Using an innovative analysis of a distant quasar observed by the 8.1-meter Gemini North telescope on Hawai‘i, operated by NSF’s NOIRLab, the scientists found an unusual ratio of elements that, they argue, could only come from the debris …

Hubble Space Telescope spots protective shield against greedy Milky Way

An odd shield of supercharged gas protects dwarf galaxies from being ripped apart by the gravitational pull of the Milky Way, 30 years’ worth of observations by the Hubble Space Telescope reveal. For years, astronomers have struggled to explain why the Large and Small Magellanic Clouds, two tiny galaxies orbiting the Milky Way, still form …

The Water-Lakes-on-Mars Debate Just Got More Interesting

This image taken by NASA’s Mars Reconnaissance Orbiter shows ice sheets at Mars’ south pole. Image: NASA/JPL-Caltech/University of Arizona/JHU Scientists have been arguing for years about ambiguous radar scans of Mars’ south pole. Do they reveal underground lakes of liquid water? Or something else? Two new papers out this week have added even more intrigue …
