We’ve always assumed that we lived in a perfectly normal star system with a normal star and normal planets. It’s all… normal. But with our modern understanding of billions of stars, just how normal is our Sun, anyway?
The Earth is teeming with life, but the upper atmosphere to kilometers underground. There’s no question that our planet has life. But is our planet itself alive?
There are general-purpose telescopes and missions that astronomers can use to study specific objects. And there are the survey missions that look at the entire sky, which astronomers can use to answer questions about the Universe.
It’s Spring in the Northern Hemisphere, and that means the Sun is back. But it’s more than just a free heat lamp for your garden, it’s an incredible, dynamic nuclear reaction complete with flares, coronal mass ejections, twisting magnetic fields and the solar wind
Knowledge moves forward, and so, we must move with it. Today we’ll give you an update on some of the most fascinating, fast-changing topics in astronomy, astrophysics and cosmology.
Although humans have never actually been to Mars, explorers have simulated many aspects of Mars missions here on Earth. There are missions under the ocean, on the tops of volcanoes, in the harsh Canadian north, and even in bed that simulate the limitations of spaceflight, and teach us many of the lessons to prepare us for the real thing.
Computers are a big part of astronomy, but mostly they’ve been relegated to doing calculations. But recent developments in machine learning have changed everything, giving computers the ability to do jobs that humans could only do in the past.
We think of space as a vacuum, but there are regions of different density. There are winds blowing from stars and other objects that clear out vast bubbles in space, and they might have been critical for Earth to even exist in the first place.
As astronomers look out across the Universe. They see various objects spewing jets of material light years into space. What causes these jets? And what impact do they have on the Universe?
The Milky Way is a vast grand spiral today, but how did it get this way? Looks like ancient collisions with dwarf galaxies is the answer. But the ancient collisions with dwarf galaxies, and how they came together to build the modern Milky Way?
