A year ago, a puzzling gap existed between black holes and neutron stars. With nearly a year of new data, LIGO solves the puzzle. On Monday, March 16, 2020, astrophysicist Carl […]
We’ve never found eight stars bound together in the same stable system. But nature might make it so. The Universe that we have is often more wondrous and bizarre than even […]
And if you have a friend at the same longitude, you can even measure its circumference. This year’s equinox, on March 19/20 of 2020 (longitude-dependent), is Earth’s earliest in 124 […]
It’s an incredibly useful approximation. But the truth takes us far deeper. Anyone who’s ever taken a physics course has learned the same myth for centuries now: that any object thrown, […]
The full Moon is always a sight worth looking at. This March, the full Worm Moon is a little more “super” than usual. The full Moon is always a spectacular sight: […]
No one has seen an equinox this early since the 19th century. And you’d better get used to it. This year, on March 19, 2020, the equinox will occur. For a […]
After the Big Bang, merging supermassive black holes are unparalleled. Here’s how we’ll find the first one. Last week, NASA’s Chandra X-ray observatory made history by announcing the most energetic explosive […]
A black hole punched a hole 15 Milky Ways across in a galaxy cluster’s gas, by far the largest ‘kaboom’ ever seen. The Universe, everywhere we look, is full of cataclysmic […]
It’s not a lack of motivation, intelligence, or capability. Here’s how to open a space. Over the past 20 years, the number of bachelor’s degrees awarded in physics has more than […]
Ever wonder, exactly, how stars form from molecular gas and dust? So do scientists. One of the great challenges for astronomy is to determine, in gory detail, how stars are […]
And how cutting just $1 billion per year in funding from NASA’s budget would be a catastrophe for science. When you think of the great cosmic beyond and what we know […]
Only one dark matter detection experiment ever gave a positive result, in conflict with all the others. This could be why. For multiple generations now, it’s been apparent to astronomers that […]
We’ve come fantastically far in our understanding of the distant Universe. Here’s how we’ll go even farther. Sometime in 2021, NASA’s James Webb Space Telescope will launch, deploy, and begin science […]
It’s been called the biggest conundrum in all of cosmology, and recent measurements just add to the confusion. One of the most puzzling facts about the Universe is that different […]
Two of our biggest science-fiction dreams might not remain fiction for much longer. Here’s how 21st-century science could make it real. For as long as human beings have looked up at […]
The NSF’s new, cutting-edge solar observatory shows us the Sun as never before. Here’s why we need to know. On December 12, 2019, the world’s most powerful solar observatory — the National Science […]
The problem is going to get a lot worse before it gets better, and the decision is all up to SpaceX whether they’ll fix it. On Wednesday morning, January 29, 2020, […]
All supernovae are not created equal. After a 14 year investigation, the brightest ones have a surprising explanation. In 2006, astronomers witnessed a supernova that defied conventional explanation. Typically, supernovae […]
The closest star to our own doesn’t just host one rocky planet, but a second, larger ‘super-Earth’ much farther out. Of all the stars in the Universe, the closest one to […]
If dark matter is fundamentally different from the normal matter we know, there should be a way to test it. Here are the results. Dark matter — despite the enormous indirect evidence for […]
The images themselves will take your breath away, but the science we can extract from them is truly revolutionary and spectacular. Dark matter may be one of the most mysterious […]
Within the next billion years, the Magellanic Clouds might merge with our galaxy. But the new stars are already here. Within the Milky Way, there are only a few instances of […]
It’s one thing to find a galaxy that “shouldn’t exist.” It’s quite another to learn why it does. Above a certain size, spiral galaxies shouldn’t exist. A single major merger — where two […]
A decade ago, we didn’t know if dwarf galaxies had black holes. Today, half of the ones we see aren’t where we expected. Normally, galaxies have supermassive black holes millions […]
The age of the Universe is only 13.8 billion years, but we know that protons survive much longer. Here’s how. Since the discovery of radioactivity in the 19th century, humanity has […]
After 13.8 billion years, there’s still a whole lot that’s changing as time goes on. With each new year that comes upon us, there are a slew of new events awaiting […]
If you’re wondering whether the blast wave or the radiation would kill us first, you’re asking the wrong question. As far as raw explosive power goes, no other cataclysm in […]
It’s a supergiant star in the final stage of its life, and it just dimmed by an enormous amount. What’s going on? When you take a look at the stars in […]
A black hole’s event horizon is thought of as the point of no return. But perhaps there are ways back out, after all. Black holes just might be the most extreme […]
In the middle of a great cosmic void, a single, isolated galaxy persists amidst the darkness. It’s about to get a lot lonelier. Here in our own cosmic backyard, the […]
