The Milky Way, our home Galaxy
The Milky Way, our home Galaxy seen edge on, features many of the sky’s best sights, and summer is the ideal season to explore them.
The first planets beyond the Milky Way may have been discovered
For the first time ever, we have discovered planets beyond our own Milky Way galaxy.
We have long been unable to find exoplanets outside the solar system beyond the confines of the Milky Way. After all, our galaxy is a warped disc about a hundred thousand light-years across and a thousand light-years thick, so it's incredibly difficult to see beyond that.
You can hear the Perseid Meteor Shower live
When a meteor enters the Earth's upper atmosphere it excites the air molecules, producing a streak of light and leaving a trail of ionization (an elongated paraboloid) behind it tens of kilometers long.
A new planet almost the size of Neptune that could vaporise you in under a second
A new planet almost the size of Neptune that could vaporise you in under a second has amazed us because it shouldn’t exist.
The exoplanet has been found in an area called the “Neptunian Desert”.
Origin of Phobos and Deimos by the impact of a Vesta to Ceres sized body with Mars
The origin of Phobos and Deimos, the two small moons that orbit close to the surface of Mars, have been hotly debated by scientists for decades.
A violent impact between Mars and another planet-sized object resulted in the birth of the Red Planet’s two moons, according to a new study.
Did a nearby supernova cause one of Earth’s mass extinctions?
About 2.6 million years ago, an oddly bright light arrived in the prehistoric sky and lingered there for weeks or months. It was a supernova some 150 light-years away from Earth. A few hundred years later, after the new star had long since faded from the sky, cosmic rays from the event finally reached Earth, slamming into our planet.
