Extremely Hot Exoplanets Can Have Extreme Weather, Like Clouds of Aluminum Oxide and Titanium Rain

   29 May 00:00:12  |  Universe Today

Thanks to the success of the Kepler mission, we know that there are multitudes of exoplanets of a type called “Hot Jupiters.” These are gas giants that orbit so close to their stars that they reach extremely high temperatures. They also have exotic atmospheres, and those atmospheres contain a lot of strangeness, like clouds made …

A Massive Rotating Disc Discovered in the Early Universe

   28 May 00:00:10  |  Universe Today

If we want to understand how the Universe evolves, we have to understand how its large structures form and evolve. That’s why astronomers study galaxy formation. Galaxies are enormous structures of stars, planets, gas, dust, and dark matter, and understanding how they form is critical to understanding the Universe itself. In 2017, astronomers working with …

The Solar System Might Not Exist if There Wasn?t a Huge Galactic Collision with the Milky Way Billions of Years Ago

   28 May 00:00:10  |  Universe Today

The Milky Way has a number of satellite galaxies; nearly 60 of them, depedending on how we define them. One of them, called the Sagittarius Dwarf Spheroidal Galaxy (Sgr d Sph), may have played a huge role when it comes to humans, our world and our little civilization. A collision between the Milky Way and …

Tiny Cardboard Aircraft Could Fly in the Skies of Mars

   27 May 00:00:16  |  Universe Today

What would be the best method for exploring planetary atmospheres, such as at Mars, Venus or even Earth? One group of researchers are developing tiny, levitating “nanocardboard” aircraft that could hover in alien skies. They would fly like dust floating in beams of sunlight ? but intelligently, and with a purpose. ?It?s exciting because it?s …

This is an Actual Image of a Planet-Forming Disc in a Distant Star System

   26 May 00:00:04  |  Universe Today

In 2017, astronomers used ALMA (Atacama Large Millimeter/sub-millimeter Array) to look at the star AB Aurigae. It’s a type of young star called a Herbig Ae star, and it’s less then 10 million years old. At that time, they found a dusty protoplanetary disk there, with tell-tale gaps indicating spiral arms. Now they’ve taken another …

Maybe a Fleet of Tiny Spacecraft Could Help Detect a Primordial Black Hole Planet 9

   25 May 00:00:05  |  Universe Today

There are eight classical planets in our solar system, from speedy Mercury to distant Neptune. There are also numerous dwarf planets, such as Pluto and Ceres. While we continue to find more dwarf planets, there are some hints that another large planet could lurk far beyond Neptune. This Planet Nine is thought to be a …
