Okay, this is an incredible and rare opportunity, but I’m so pleased to announce that next January, from the 18th-24th, 2019, I’ll be leading an exclusive AstroTour of Iceland! We’ll […]

There are many arguments over what makes a theory beautiful, elegant, or compelling. But in the face of data, predictive power is everything. When you look at any phenomenon in […]

The Universe may defy our intuition, but that’s what science is for! If you take a look out at the Universe, and in every direction you look, you see objects rushing […]

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 […]

There’s nothing new, recent, or remarkable about it. It’s just a typical cosmic pebble in the galactic ocean. Last year, the interstellar interloper ʻOumuamua passed through the inner Solar System. Originally […]

What do our future missions in physics, astronomy, astrophysics and more hold? If you went back in time just 30 years, the world as we it was a completely different place. […]

Are we looking for life in all the wrong ways, like SETI with smoke signals? A little over 80 years ago, humanity first began broadcasting radio and television signals with enough […]

They’re less than a billion years old. And, thanks to ALMA, they might finally pave the way to understanding how galaxies form. How do galaxies like our Milky Way come to […]

They’re the fastest rotators of all. So how distorted are they? There are very few objects in the Universe that stand still; almost everything we know of rotates in some way. […]

What if alien life — or even intelligence — don’t look like what we’re searching for? When the original Star Trek premiered, it was revolutionary for depicting sentient, intelligent species other than humans, living […]

How did black holes get so supermassive so fast? Astrophysics may be about to find out, thanks to three big 2017 discoveries. There’s a big problem when we look at […]

The ‘big discovery’ is nothing of the kind. We need a new planet-finding mission to probe the next frontier. Last week, NASA dropped a bombshell that it’s Kepler mission — the greatest […]

If you haven’t finished your holiday shopping yet, consider these 10 gifts, good any time of year! One of the hardest things when it comes to holiday shopping is to find […]

We’ve come so far since 2015; what do we know about dark matter now that we didn’t know then? Back in 2015, the dark matter situation was pretty straightforward: the large-scale […]

If December’s best natural sky show seems to get better every year, it isn’t your imagination. It’s science, and it’s spectacular! Every year, the Earth travels some 940 million kilometers […]

There’s so much that we’ve discovered, looking as deeply as possible into the void. But what are we missing? Start with the laws of physics, a Universe full of a specific […]

Just because it isn’t Thanksgiving anymore doesn’t mean we don’t have an entire Universe to be thankful for. Every day, we have a choice whether we take our lives, our existence, […]

No matter what the science says, there’s no excuse for cruel behavior to a colleague. Look out into the distant Universe as far as you possibly can, and you’ll come […]

If the gravity isn’t where the matter is, things get into trouble very, very quickly. The above image, a composite of optical data, X-ray data, and a reconstructed mass map, is […]

The first stars formed almost half a billion years before we could see their light. Here’s why. At the moment of the Big Bang, the Universe was full of matter and […]

Very sure. Here’s how we know. You’ve no doubt heard that the Universe itself has been around for 13.8 billion years since the Big Bang, and that scientists are extremely confident […]

For the first time, we’ve seen neutron stars merge. At last, the gravitational and electromagnetic sky are one. “It’s becoming clear that in a sense the cosmos provides the only laboratory […]

From the most beautiful to the most impactful, some of these are so powerful it’s breathtaking. “Truth in science, however, is never final, and what is accepted as a fact […]

Why the 2017 Nobel Prize isn’t the end, but the start, of something really, really big. “Wormholes are a gravitational phenomena. Or imaginary gravitational phenomena, as the case may be.” –Jonathan […]

A well-deserved award for the discovery over a century in the making. “Well, I walked into Building 20 and looked in at the various little labs. There was a bunch of […]

Why not just put your detectors in place of a giant mirror? “Look and think before opening the shutter. The heart and mind are the true lens of the camera.” –Yousuf […]

Three eyes are so much better than two. Here’s why. “Einstein’s gravitational theory, which is said to be the greatest single achievement of theoretical physics, resulted in beautiful relations connecting gravitational […]

If you think we’ve seen all there is to see in the Universe, you’re about to have your imagination unlocked. “Hubble often takes images of distant gravitationally lensed galaxies to […]

The ELT, at 39 meters in diameter, will dwarf everything that’s ever come before. “There are so many people who are arguing or fighting over issues which don’t have much relevance. […]

Last week, Cassini plunged into Saturn’s atmosphere. Here are the top 6 things we learned from it while it was alive. “Being a scientist and staring immensity and eternity in the […]
