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.
It is projected to last for more than 100 minutes, and begins Friday July 27.
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.
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 […]
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 […]
A Japanese astronomer shows that the Milky Way galaxy was formed in two stages, “dying” in between.
What defines a dark horse? The all-important decision to pursue fulfillment and excellence.
The Perseid meteor shower during this weekend’s new moon should be fabulous.
While observing a young star system, astronomers noticed the star had a small, mysterious companion in its orbit.
Not so long ago, we had better maps of Mars than of Antarctica. Now, Antarctica is the best-mapped continent in the world.
Although there is much guesswork as to the future of artificial intelligence, today’s AI systems continue to be a boon for science.
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 […]
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 […]
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 […]
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.
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 […]
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 […]
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, […]
The astrophysicist Dame Jocelyn Bell Burnell has been awarded a special Breakthrough prize for discovering pulsars in the 1960s.
Astronomers were using images taken by Hubble Space Telescope to study a supernova when they detected an unusually strong source of light later determined to be a star.
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 […]
You’ve probably seen it hanging around. But how did it get there? And can we live there?
The current record-holder is a doozy, and right at the limit of what Hubble can do. But there’s even more out there. The greatest advances in science often come when we […]
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 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 […]
An asteroid about the size of a New York City block is flying between the Earth and the Moon today. How close, though?
It will take further study to confirm the star’s iron influx came from a planet or two, but the initial theory is quite compelling.
Bright pink? Lava? Liquid planets that could hold water? Some far-out planets are truly… out of this world.
If everything goes right, astronomy will take a magnificent leap into the future. But here’s what needs to happen first. Back in 2000, NASA held their decadal survey, choosing what would […]
