Topline A near-Earth asteroid as wide as the Statue of Liberty is tall has been discovered that could strike Earth in 2032. It’s triggered a rare warning by the International Asteroid Warning Network, which NASA chairs. There's a 1.3% chance that asteroid 2024 YR4 could strike Earth ...

Astronomers say they've detected a mysterious type of signal known as a fast radio burst coming from an ancient, dead galaxy billions of light years away. Figuratively speaking, it makes for one hell of a sign of life.  The findings, documented in two studies published in The Astrophysical ...

As far as supermassive black holes go, the one at the center of the Milky Way is relatively sedate. But, even in its supposed quiescent state, Sagittarius A* is prone to the occasional belch or rupture – and now, using JWST, astronomers have recorded it doing something we've never seen ...

There might not be a mysterious 'dark' force accelerating the expansion of the Universe after all. The truth could be much stranger – bubbles of space where time passes at drastically different rates. The passage of time isn't as constant as our experience with it suggests. Areas of ...

It's the year 2000. We're floating in space, and we come across the side view of a spectacular spiral galaxy. It's called UGC 10043 and is located 150 million light-years away. Spiral galaxies like this one are vast structures of stars, gas and dust, characterized by swirling arms that ...

According to a new study, our Milky Way galaxy may have already begun colliding with the closest giant galaxy, Andromeda. Published in Nature Astronomy, the study reveals that there may be a shroud of gas around every galaxy that stretches up to a million light years. If that’s the ...

What are they? Earlier this year, astronomers revealed one of the James Webb Space Telescope's most spectacular and intriguing discoveries yet — and that's saying something. Lying in one of the most ancient regions of the observable universe, they found, were hundreds of galaxies that ...

Astronomers often have more questions than answers about the universe — and the universe, in turn, has asked its own question. Quite literally. Last year, the James Webb Space Telescope fortuitously spotted the unmistakable shape of a question mark across the sky. The uncanny feature was ...

What comes to mind when you think of space? Imagine a friend boasting about a spacious building, stadium or museum they recently visited. Do you envision the building as vast and expansive? Is it simply very large, or does it seem empty? The word spacious does not necessarily mean empty. ...

Warp drives have a long history of not existing, despite their ubiquitous presence in science fiction. Writer John Campbell first introduced the idea in a science fiction novel called Islands of Space. These days, thanks to Star Trek in particular, the term is very familiar. It's almost ...

Andromeda is the closest major galaxy to our Milky Way – and it's getting closer. In fact, astronomers believe that the two galaxies are destined to crash into each other. But a new study suggests this fate isn't necessarily written in the stars. Andromeda is currently barreling down ...

I bet there are still some people among you who still don't think bases on the Moon and trips to Mars are things we just might experience during our lifetimes. But you only have to look at the intense prep work the world's space agencies and private companies are conducting, and at the fortunes ...

Saturn has its famous hexagon, and Jupiter has just now been caught throwing mad shapes too. High up in its atmosphere, astronomers have identified strange, glowing new features, in the region above the tempestuous Great Red Spot. There, in the ionosphere, concentrations of ionized ...

A rogue planet is a world that has been ejected from the planetary system in which it originally formed. Because rogue planets do not orbit a parent star, they are cast adrift into interstellar space. On their meanderings, rogue planets are pulled toward whatever large, gravitationally ...

A manned mission to Mars is a long-term goal of the scientific community. However, a new study has presented a significant challenge to this objective: human kidneys may not endure the long trip to the Red Planet. While scientists are already considering potential solutions, much more research ...

We've received a strange signal from across the galaxy, and astronomers are struggling to understand what it means. They know what's emitting the signals. It's a neutron star named ASKAP J193505.1+214841.0 (ASKAP J1935+2148 for short), located in the plane of the Milky Way, some 15,820 ...

Within the last five years, astronomers have discovered a new type of astronomical phenomenon that exists on vast scales – larger than whole galaxies. They're called ORCs (odd radio circles), and they look like giant rings of radio waves expanding outwards like a shockwave. Until now, ORCs ...

Meteors – commonly known as shooting stars – can be seen on any night of the year. But some nights are better than others. As Earth moves around the Sun, we encounter streams of dust and debris from comets and asteroids. That debris gives birth to "meteor showers" – times when the number ...
