The origin story for our Universe got a major revision nearly 40 years ago. Time to catch up. 13.8 billion years ago, all the matter and energy contained within our Universe […]

It’s one of cosmology’s biggest unsolved mysteries. The strongest argument against it may have just evaporated. The ultimate goal of cosmology contains the greatest ambition of any scientific field: to […]

Simply getting into grad school isn’t enough. The answers to these three questions can make all the difference. It’s time. You’ve done all your research into schools, completed your undergraduate […]

If you think that the Moon is only good for reflecting sunlight, you’ve got another think coming. To human eyes, the Moon is the second brightest visible object, trailing only the […]

It’s much more complex a question than dividing its mass by the volume of the event horizon. If you want to get a meaningful answer, you have to go deep. If […]

Or, quite possibly, is it more complex than either one of those scenarios? If there’s one lesson that humanity should have learned from the 20th century, it’s this: the Universe […]

Jim Peebles, Michel Mayor and Didier Queloz just won the 2019 Nobel Prize in Physics. It couldn’t be more well-deserved. Every year, the Nobel Prize reminds all of humanity to […]

A recent headline claimed they could. But if gamma-rays are just a form of light, don’t they have to travel at light-speed? There’s an ultimate speed limit in the Universe: […]

We know a lot about what else is out there, but we still don’t know everything. In the quest for life in the Universe, it makes sense to look at […]

There’s so much we don’t know about fast radio bursts and galactic halos. Combined, we get a unique window on the Universe. Deep in space, mysterious signals known as Fast […]

Every object in the Universe is constrained by the laws of physics. Does this mean there are any black holes that shouldn’t exist? When it comes to the objects that […]

If you thought the Planck satellite just made temperature maps of the cosmic microwave background, this will astound you. The Milky Way, to human eyes, appears as simply a mix of […]

Maybe, but that probably doesn’t mean what you think it does. Of all the unsolved puzzles in the Universe, perhaps the most confounding is the dark matter problem. If we look […]

The Sudbury neutrino observatory, which was instrumental in demonstrating neutrino oscillations and the massiveness of neutrinos. With additional results from atmospheric, solar, and terrestrial observatories and experiments, we may not […]

It’s a great scientific opportunity of modern times, but we won’t get there with our current observatories. One of the holy grails of modern science is to find a world, […]

As more data comes in, the puzzle gets deeper and deeper. Whenever you set out to solve a problem, there are a series of steps you have to take in order […]

What’s more massive than the heaviest known neutron star but lighter than the lightest known black hole? LIGO may be about to solve that mystery. Whenever a star is born in […]

You’ve seen a black hole’s event horizon for the first time thanks to them. But they’re only getting started. Earlier this year, 2019, the Event Horizon Telescope collaboration revealed the first […]

The darkness of the night sky was a mystery for generations of humans. Here’s the reason why. From our perspective here in the Solar System, it makes absolute intuitive sense why […]

Black holes are regions of extreme gravity, but dark matter barely interacts at all. Do they play well together? Black holes are some of the most extreme objects in the […]

It’s the largest, most massive planet in the Solar System. But what’s the real story behind all the impacts on Jupiter? One of the most terrifying prospects here on Earth is […]

We’re one step closer to solving the mystery of how they get so big so fast. A great cosmic mystery for science is explaining how supermassive black holes form. An ultra-distant […]

After Kepler but before James Webb, TESS is preparing astronomers for the coming exoplanet revolution. There are always new discoveries and achievements occurring in science, and certain fields have experienced […]

The top of Mauna Kea is the ideal physical site for this new, ready-to-be-built telescope. But that’s far from the only concern. For many years, astronomers have looked forward to a […]

Many of them are spinning at nearly the speed of light. When you do the math, there’s no other way it could have been. Take a look out there at the […]

What makes Uranus and Neptune-like worlds so fascinating? If you only knew. What do we really know, and what mysteries are left to solve, about the outer worlds of our Solar […]

When you’re trying to peel back the veil obscuring the fundamental nature of matter, you have to look absolutely everywhere. Sometimes, the solution to a puzzle you’ve been stymied by […]

The dream of multi-messenger astronomy is to seen an event with gravitational waves, neutrinos, and light all together. The newest candidate just might get us there. When it comes to cataclysmic […]

And it’s not because of leap seconds; it’s a fundamental property of most days. Human beings, in marking the passage of time, account for each day equally: with 24 hours. One […]

It’s not a question of could they, but have they? Here’s how we’ll find out. It’s no secret that fragments of asteroids, comets, and other spaceborne objects have been found here […]
