Hubble Finds Buckyballs in Space

For the first time, NASA's Spitzer Space Telescope has detected little spheres of carbon, called buckyballs, in a galaxy beyond our Milky Way galaxy. The space balls were detected in a dying star, called a planetary nebula, within the nearby galaxy, the Small Magellanic Cloud. What's more, huge quantities were found -- the equivalent in mass to 15 of our moons. An infrared photo of the Small Magellanic Cloud taken by Spitzer is shown here in this artist's illustration, with two callouts. The middle callout shows a magnified view of an example of a planetary nebula, and the right callout shows an even further magnified depiction of buckyballs, which consist of 60 carbon atoms arranged like soccer balls. In July 2010, astronomers reported using Spitzer to find the first confirmed proof of buckyballs. Since then, Spitzer has detected the molecules again in our own galaxy -- as well as in the Small Magellanic Cloud. Image Credit: NASA/JPL-Caltech

Scientists working with the Hubble Space Telescope have found a very complex molecule out there in space. Called Buckyballs, after renowned thinker Buckminster Fuller, they are a molecular arrangement of 60 carbon atoms (C60) in the rough shape of a soccer ball. Though it’s not the first time these exotic molecules have been spotted in space, it is the first time that Buckyball ions have been found.

NASA Model Shows Greenland’s Ice Sheet Will Disappear Over the Next 1000 Years, Raising Sea Levels by 7 Meters

Great news! Humankind’s greatest-ever engineering project is nearing completion. Soon we will have warmed the Earth enough to get rid of all those pesky ice sheets and other frozen areas. The finish line is in sight.

If we all work together for the next thousand years, we’ll finally reach our goal!

Deep Space Atomic Clocks Will Help Spacecraft Answer, with Incredible Precision, if They’re There Yet

The Deep Space Atomic Clock, a new technology from NASA's JPL, may change the way spacecraft navigate in space. Launching in late June aboard the Orbital Test Bed satellite, on the SpaceX's Falcon Heavy rocket, descendants of the technology demonstration could be a key component of a self-driving spacecraft and a GPS-like navigation system at other worlds.Credit: General Atomics Electromagnetic Systems

How do spacecraft know where they are? There’s no GPS out there. Right now, it involves sending a signal to the spacecraft which the spacecraft then sends right back to Earth. The elapsed time reveals the distance.

But on June 24th, that method could be replaced by something much more autonomous.

The Earliest Example of Merging Galaxies Ever Found

Galaxy mergers are not particularly rare, but they are important events. Not only for the galaxies involved, but for scientists trying to piece together how galaxies evolve. Now, astronomers using ALMA have found the earliest example yet of merging galaxies.

Saltwater Similar to the Earth’s Oceans has been Seen on Europa. Another Good Reason Why We Really Need to Visit This Place

Jupiter’s moon Europa is an intriguing world. It’s the smoothest body in the Solar System, and the sixth-largest moon in the Solar System, though it’s the smallest of the four Galilean moons. Most intriguing of all is Europa’s subsurface ocean and the potential for habitability.

If you want to know what a talent for scientific visualizations looks like, check out Eleanor Lutz. She’s a PhD student in biology at the University of Washington, and at her website Tabletop Whale, you can see her amazing work on full display.

Her latest piece is a map showing all the orbits of over 18,000 asteroids in the Solar System. It includes 10,000 asteroids that are over 10km in diameter, and about 8,000 objects of unknown size.

Mimas Pushes Through Saturn’s Rings Like a Snowplow

Saturn's rings and moons have been the subject of scientific debate. A 2019 study showed that the migration of Saturn's moons has widened the Cassini Division in Saturn's rings. Image Credit: Cassini, Dante, Baillié and Noyelles

Saturn’s moon Mimas is the smallest of the gas giant’s major moons. (Saturn has 62 moons, but some of them are tiny moonlets less than 1 km in diameter.) Two new studies show how Mimas acted as a kind of snow-plow, widening the Cassini division between Saturn’s rings.

That Explains a Lot. The Moon’s Largest Crater has a Chunk of Metal Embedded in it That’s 5 Times Bigger than the Big Island of Hawaii

One of the largest craters in the Solar System is on our Moon. It’s called the South Pole-Aitken (SPA) basin and it’s 2,500 km (1,600 mi) in diameter and 13 km (8.1 mi) deep. A new study says that the basin may contain an enormous chunk of metal that’s larger than Hawaii’s Big Island.

There’s a Ring of Cool Gas Wrapped Around the Milky Way’s Supermassive Black Hole

There’s a lot going on at the center of our galaxy. A supermassive black hole named Sagittarius A-Star resides there, drawing material in with its inexorable gravitational attraction. In that mind-bending neighbourhood, where the laws of physics are stretched beyond comprehension, astronomers have detected a ring of cool gas.

Different Conditions From Earth Drive the Movement of Sand Dunes on Mars

Mars is a sandy planet and the HiRISE camera on the Mars Reconnaissance Orbiter (MRO) has given us tons of beautiful pictures of Martian sand dunes. But Mars’ dunes are much different than dunes here on Earth. Their movement is governed by different factors than Earth dunes.
