How the Solar System Got Its ‘Great Divide’ and Why It Matters

Scientists, including those from CU Boulder, have finally scaled the Solar System’s equivalent of the Rocky Mountain range. In a study recently published in Nature Astronomy, researchers from the United States and Japan unveil the possible origins of our cosmic neighborhood’s “Great Divide.” This well-known schism may have separated the Solar System just after the Sun first ...

Scientists Find Evidence That Venus Has Active Volcanoes

New research led by Universities Space Research Association (USRA) and published in Science Advances shows that lava flows on Venus may be only a few years old, suggesting that the planet could be volcanically active today — making it the only planet in our solar system, other than Earth, with recent eruptions. Dr. Justin Filiberto, the study’s lead ...

Astronomers Catch Wind Rushing Out of Galaxy

Exploring the influence of galactic winds from a distant galaxy called Makani, UC San Diego’s Alison Coil, Rhodes College’s David Rupke, and a group of collaborators from around the world made a novel discovery. Published in Nature, their study’s findings provide direct evidence for the first time of the role of galactic winds — ejections of ...

Clouds on Jupiter Rising Up Above the Surrounding Atmosphere

Though it looks like it to us, clouds on Jupiter do not form a flat surface. Some of Jupiter’s clouds rise up above the surrounding cloud tops. The two bright spots in the right-center of this image are much higher than the surrounding clouds. Jupiter’s clouds extend deep into the planet Jupiter’s atmosphere is a ...

From Points of Light to Worlds: Exploring the Solar System

A determined bunch of scientists set out to map the Moon in preparation for the Apollo landings, but that was only the beginning. A new field of science blossomed, and UA scientists have been involved in nearly every U.S. space mission since expanding out to the Solar System. Here’s a fun thought: Imagine if University ...

NASA Finds a Large Amount of Water in an Exoplanet’s Atmosphere

Much like detectives study fingerprints to identify the culprit, scientists used NASA’s Hubble and Spitzer space telescopes to find the “fingerprints” of water in the atmosphere of a hot, bloated, Saturn-mass exoplanet some 700 light-years away. And they found a lot of water. In fact, the planet, known as WASP-39b, has three times as much ...

Could Our Sun Have a Long-Lost Twin?

The Sun has been the center of our galaxy for assumingly millions or even billions of years. It has a volume of 1 million earths and accounts for more than 99 percent of the mass in our solar system. Up until recently, most people, including scientists, have believed there is only one Sun like ours. ...
