It’s rare but spectacular when the Moon passes in front of another planet. Here’s how to see it. From our perspective on Earth, the night sky appears virtually unchanged with the […]

‘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 […]
Is The Goblin’s orbit a breadcrumb leading us to Planet X?
In 1990, the Hubble Space Telescope was launched, leading to a revolution in astronomy. But for many purposes, Earth is still the best place to be. When you think about what’s […]
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 […]
Intelligent aliens, if they exist in the galaxy or the Universe, might be detectable from a variety of signals: electromagnetic, from planet modification, or because they’re spacefaring. But we haven’t […]
The concept was likened to a porch light in our little neighborhood of the galaxy.
A new book tells the very old story in a fun way for a younger generation.
No matter what Martin Rees or anyone else says, physics dictates that the world is safe. The Large Hadron Collider is the world’s most powerful particle accelerator. An aerial view of […]
What defines a dark horse? The all-important decision to pursue fulfillment and excellence.
We’ve put so much together about the Universe. Could it all come tumbling down? We’re always on the lookout for the next big thing, and even our best guesswork is often […]
It is projected to last for more than 100 minutes, and begins Friday July 27.
It wasn’t just the Milky Way and Andromeda two billion years ago. Here in the Local Group, our two largest galaxies dominate: Andromeda and the Milky Way. Our Local Group of […]
Galaxy NGC 1277 is revealed as a relic galaxy that’s barely changed since it formed 10 billion years ago, giving scientists a rare chance to look into the past.
One of astronomy’s most iconic sights in an artifact of faulty optics. Here’s how a new, great design will overcome it. When you look out at the greatest images of the […]
A Japanese astronomer shows that the Milky Way galaxy was formed in two stages, “dying” in between.
The Perseid meteor shower during this weekend’s new moon should be fabulous.
Not so long ago, we had better maps of Mars than of Antarctica. Now, Antarctica is the best-mapped continent in the world.
These cosmic behemoths were enormous from very early times. Here’s how they came to be. One of the biggest challenges for modern astrophysics is to describe how the Universe went from […]
The Universe is expanding, but we, our planet, solar system and galaxy all aren’t. Here’s why. Take a look out at almost any galaxy in the Universe, and you’ll find it’s […]
While observing a young star system, astronomers noticed the star had a small, mysterious companion in its orbit.
If dark energy is causing the Universe to disappear, how can we still find and see ultra-distant stars and galaxies? In the 1920s, scientists discovered that the Universe was expandingbased […]
Although there is much guesswork as to the future of artificial intelligence, today’s AI systems continue to be a boon for science.
The result validate Einstein on a whole new scale, and pose serious problems for alternative, modified theories of gravity. In 1915, Albert Einstein put forth a new theory of gravity: General […]
The astrophysicist Dame Jocelyn Bell Burnell has been awarded a special Breakthrough prize for discovering pulsars in the 1960s.
After generations of speculations, we’ve finally got the images that tell us the full story. Some 4.5 billion years ago, our Sun and Solar System were born from a collapsing cloud […]
Space X successfully launches TESS, the Transiting Exoplanet Survey Satellite a.k.a. “The Planet Hunter.” NASA will use it to search for planets that may support extraterrestrial life.
White dwarfs, neutron stars, and brown dwarfs aren’t actually stars at all. Here’s why. When it comes to stars, there’s a huge variety of different types out there. Our Sun is […]
If you think it expanded faster than light-speed, you need to read this. If the Universe is 13.8 billion years old, and the speed of light is truly our cosmic speed […]
Imagine looking at one saturated pixel for years on end, and somehow learning what worlds live around it. That’s what science is for! When you think of what’s out there in […]
