Astronomers Discover Icy Earth-Sized Exoplanet

Astronomers Discover Icy Earth-Sized Exoplanet

An international team of astronomers has discovered an Earth-sized planet orbiting a star at the same distance we are from the Sun. But its star is much smaller and cooler than our own, and the planet is likely an icy world more similar to Pluto. The discovery, reported in the Astrophysical Journal Letters, was possible thanks…

These Are The Closest Views Of Saturn We've Ever Seen

These Are The Closest Views Of Saturn We've Ever Seen

NASA’s Cassini spacecraft has just flown closer to Saturn than ever before – and returned some incredible photos in the process. The spacecraft flew just 3,000 kilometers (1,900 miles) from the cloud tops of Saturn yesterday, and within 300 kilometers (200 miles) of the planet’s inner edge of its rings. This is the first time…

New Galaxy Simulations Support Dark Matter Theory

New Galaxy Simulations Support Dark Matter Theory

Dark matter was first suggested to explain the weird rotation of galaxies, yet almost 50 years afterward, we still have no clue if it exists or what it is. Over the last 15 years, astronomers have relied more and more on simulations to see if the theoretical predictions of dark matter actually do match the observations. And…

Mars Shows Evidence Of Chaotic Early Solar System

Mars Shows Evidence Of Chaotic Early Solar System

Scientists have found evidence on Mars that supports the idea our Solar System went through a tumultuous period. The findings, led by the Southwest Research Institute (SwRI) in Texas and the University of Arizona, were published in Nature. The idea of our Solar System going through a late heavy bombardment (LHB) 4.1 to 3.8 billion years…

The Discoverer Of The Ring Nebula Has Finally Been Confirmed

The Discoverer Of The Ring Nebula Has Finally Been Confirmed

The Ring Nebula is one of the most incredible sights in the sky and its discovery has been historically attributed to French astronomer Antoine Darquier de Pellepoix. But recent archival work, conducted by Professor Donald Olson from Texas State University and Italian astro-historian Giovanni Maria Caglieris, revealed that he was not the first. The discoverer…

Cassini Reveals We Live In A Smaller Bubble Than We Thought

Cassini Reveals We Live In A Smaller Bubble Than We Thought

If you feel like you live in a bubble, cut off from the wider universe, you’re right. The bubble is also smaller and more rounded than many suspected. The heliosphere, caused by the Sun’s solar wind, really is almost spherical, rather than having a long trailing tail. The Sun spits out high-speed charged particles, whose…
