Until recently, we were only able to view Venus’s surface with radar or by landing on the planet. It was believed that Venus’s surface was entirely obscured by clouds; NASA’s Parker Solar Probe proved otherwise.
For the first time, light that comes from behind a black hole has been spotted.
If it weren’t for the intricate rules of quantum physics, we wouldn’t have formed neutral atoms “only” ~380,000 years after the Big Bang.
We haven’t discovered life beyond our Solar System yet, but we’re closer than ever before. Over the past 30 years, we’ve gone from zero exoplanets to thousands. With each new […]
The Universe certainly formed stars, at one point, for the very first time. But we haven’t found them yet. Here’s what everyone should know.
And what might we learn as we collect new, never-before-seen data? If you took one of history’s top scientists from 100 years ago and dropped them into today’s world, what […]
Gamma-ray bursts are among the most energetic cosmic events of all. On October 9, 2022, a remarkable one occurred: the brightest ever seen.
A new survey, the DESI Legacy Imaging Survey, has found more lenses than all others put together. One of Einstein’s most revolutionary predictions is that mass bends light. During a […]
An almost 40-year-old theory finally has ‘smoking gun’ evidence for it. During most of their lives, stars burn stably, changing imperceptibly. The rotten egg nebula, at lower right (and shown in […]
We think of physical reality as what objectively exists, independent of any observer. But relativity and quantum physics say otherwise.
Whether or not life exists elsewhere in the Universe, we can be assured of one thing: We are the only human beings in the cosmos.
Black holes aren’t just the densest masses in the Universe, but they also spin the fastest of all massive objects. Here’s why it must be so.
Move over, Tattooine, and instead feast your eyes on GW Orionis.
California’s Bobcat Fire has reached Mount Wilson Observatory’s doorstep. 100 years ago, our understanding of the Universe was very different from what it is today. Einstein’s General Relativity, our theory […]
60% of all potentially dangerous asteroids remain undetected.
How two seemingly distinct exoplanet systems turned out to be related. Practically every star in the Milky Way has a similar origin story. At some point in the past, a molecular […]
From physics and alchemy to theology and eschatology, Isaac Newton’s research was rooted in a personal pursuit of the Divine.
The newest record-setting quasar houses an enormous black hole. No one knows how. In every scientific field, we’re always on the lookout for whatever new discovery might reveal what’s currently beyond […]
There will always be “wolf-criers” whose claims wither under scrutiny. But aliens are certainly out there, if science dares to find them.
If you thought it was just one rich region in space, look deeper and wider. Shining brilliantly in January’s skies is the Great Orion Nebula. By 10 PM every night in […]
Scientists should be cautious when expressing an opinion based on little more than speculation.
If you want to understand what the Universe is, how it began, evolved, and will eventually end, astrophysics is the only way to go.
For the cosmos, it’s all too easy being green. Stars come in a wide variety of colors, but never green. Stars form in a wide variety of sizes, colors and masses, […]
A new study shows our planet is much closer to the supermassive black hole at the galaxy’s center than previously estimated.
In the 20th century, many options abounded as to our cosmic origins. Today, only the Big Bang survives, thanks to this critical evidence.
A new study proposes mysterious axions may be found in X-rays coming from a cluster of neutron stars.
The Universe is supposed to be the same everywhere and in all directions. So what’s that giant “cold spot” doing out there?
NASA’s SOFIA mission is upgraded and back in action, and the Cigar Galaxy makes a perfect target. In theory, cold, neutral gas is the key to stars and galaxies. A visualization […]
Binary black holes eventually inspiral and merge. That’s why the OJ 287 system is destined for the most energetic event in history.
