Explore the discoveries that reveal how the world works, alongside the technologies that extend, reshape, and sometimes challenge what’s possible.
Everyone in the Universe needs a break sometimes. They say that all work and no play make Jack a dull boy, and with very few exceptions, I’ve been working hard […]
Sedna could be the very first known object from the Inner Oort Cloud. But time is running out to create and launch a mission. In 2003, scientists discovered an object beyond […]
Every professional organization of scientists has a code of ethics and/or conduct. Why not apply it to their journals? When it comes to exploring the Universe, many young people get […]
Even before we have the James Webb Space Telescope, a controversy over when the first stars formed is growing. As far back as our most powerful telescopes have ever looked, we’ve […]
If dark energy were stronger or weaker, everything would be pretty much the same. And that’s a puzzle. After the Big Bang, the Universe was full of matter and radiation. It […]
The ingredients for life are everywhere, but so far the only life we know of comes from Earth. Here’s how that might change. Ever since human beings first turned our eyes […]
One of the night sky’s most famous sights isn’t what it appears to be. Perhaps the most famous sight of a dying star is the Ring Nebula, known since 1779. The […]
Dark energy tells us that the Universe’s expansion is accelerating. Here’s what that means for our disappearing Universe. One of the biggest surprises for humanity about the Universe is that […]
In the search for the youngest planet in the Universe, astronomers may have accidentally stumbled upon something entirely new. Growing up is hard to do in the Universe. In the great […]
In 2015, the ultra-distant galaxy CR7 was measured to have hydrogen and helium, but no carbon or oxygen. With new ALMA observations, there’s carbon after all. As brilliant as our Universe’s […]
In 2015, the United States brokered a revolutionary international deal with Iran about their nuclear programme. Here’s the science behind it. In 2015, a historic agreement was reached between Iran and […]
‘Luck’ is the wrong word. The Universe cooperated, but we gave ourselves the opportunity by being prepared. It was already 28 years ago that the Hubble Space Telescope was launched […]
The solar neighborhood is so different than people imagine. But for the first time, we know what it’s like. When you look up at the stars in the night sky, they […]
Whatever you do, don’t try to wash it away with water. Every few months, a volcanic eruption occurs on Earth, with lava flows and enormous plumes of volcanic ash. In 2015, […]
We see matter, but not antimatter, in our Universe. Could black holes be the answer? One of the greatest cosmic puzzles in our entire Universe is why there’s so much more […]
Just one equation relates the expansion of space to all the matter and energy we have. If you know this, you can know the fate of the Universe. Last week, […]
The picture itself is breathtaking. But what we learn is truly eye-opening. Galaxy clusters, like the massive one captured here by Hubble, PLCK G004.5–19.5, impress not just for their looks, […]
If it can stretch the Universe from the size of a subatomic particle to billions of light years in a fraction of a second, why doesn’t Einstein’s relativity forbid it? When […]
Among the general public, people compare it to the aether, phlogiston, or epicycles. Yet almost all astronomers are certain: dark matter and dark energy exist. Here’s why. If you go by […]
It took the Universe 9.2 billion years to create the Earth, and another 4 billion for complex life. Could we have gotten there faster? The story of how the Universe came […]
