It’s often the case that the more that planets are studied and understood, the more remote the possibility of inhabiting them seems. Mars, for example, is the closest celestial body to Earth in terms of distance, but data shows its conditions are extremely hostile for life. Despite this, NASA has plans to send astronauts to the Red Planet, and Elon Musk is a vocal proponent of establishing a human presence there. In the short term, the solution to colonizing Mars is the construction of special

Earth’s meteorite collection just got called out for being a little biased—and what’s more, a team of astronomers pinpointed exactly why that bias occurs. Carbonaceous asteroids are all over our solar system, both in the main belt and closer to Earth. But very few of the carbon-rich rocks are actually found on Earth, comprising just 4% of the meteorites recovered on our planet’s surface. The astronomical team wanted to understand what causes the discrepancy. Their findings, published today in

Rather, it’s asteroids a size range down—those upwards of 460 feet (140 meters) long—that are of paramount concern. About 25,000 of those are thought to exist close to our planet, and just under half have been found. The day-to-day odds of an impact are extremely low, but even one of the smaller ones in that size range could do significant damage if it found Earth and hit a populated area—a capacity that has led astronomers to dub such midsize asteroids “city killers.” If we find a city killer

A few months ago, an asteroid created quite a buzz. At one point, asteroid 2024 YR4 had a 3.1% chance of hitting Earth, creating plenty of headlines about its potential impact. The threat is all but gone, but we now have pictures of the once-worrisome asteroid. NASA's James Webb Space Telescope captured images of the asteroid with two cameras, including the Near-Infrared Camera and the Mid-Infrared Instrument. The former measures reflected light, while the latter shows thermal energy. The image

After taking another peek at the "city-killer" asteroid that once had a small but uncomfortable chance of smashing into our planet, astronomers have figured out what it actually looks like: a flat, spinning disk. The preferred analogy has been to compare the shape to a hockey puck. To us, this sounds like a huge missed opportunity to say that the Earth was — however briefly — under threat by a literal flying saucer, just like in that one movie. The findings come from a preprint study, accepted

A newly discovered asteroid is on track for a close brush with Earth—and it might even slam into the Moon. Recently, astronomers got a closer look at the giant space rock, revealing its violent origin story. Using the Keck Observatory on Maunakea, Hawaiʻi Island, a team of astronomers was able to identify the physical properties of asteroid 2024 YR4 and uncover its potential origin. The menacing asteroid may have broken off from a larger space rock following a collision. It also likely originat

Remember the potential "city killer" asteroid we were all freaking out about, 2024 YR4? Initially predicted with a small but unsettling chance of hitting our planet seven years from now, astronomers eventually ruled out that apocalyptic outcome once they were able to get better observations. But the saga's not over. 2024 YR4 will be back for another pass, Athabasca University astronomer Martin Connors writes in an essay for The Conversation — and there'll be others like it.

The classic arcade game Asteroids is so accessible and timeless that every time I see a vector graphics triangle, it acts as a reminder of the retro gaming era. The original arcade cabinet hit the scene in 1979, while the more familiar Atari 2600 title debuted in 1981. Forty-five years after the game’s debut, Atari worked with watch brand Nubeo to create a series of limited edition mechanical timepieces to mark the anniversary.

The Hera probe has swung around Mars, using the planet’s gravitational pull to fling itself toward its asteroid target. During its brief rendezvous with the Red Planet, Hera caught a glimpse of the less-seen side of Mars’ smaller, tidally-locked moon as it orbited its home planet. The European Space Agency (ESA) launched its Hera mission on October 7, 2024, to inspect the damage caused by NASA’s DART mission (Double Asteroid Redirection Test) when it smashed into an asteroid to redirect its orb

It was a swing and a miss for the first private attempt at an asteroid mission, but the company is still chalking it up as a win. California startup AstroForge launched a spacecraft dubbed Odin on February 26, but the team lost communication with it shortly after its launch on a SpaceX Falcon 9 rocket. "The chance of talking with Odin is minimal, as at this point, the accuracy of its position is becoming an issue," the company said in its extensive debrief of the mission. Technical issues occur

Over the following weeks, the probability of a collision grew steadily, eventually reaching 3.1 percent — or about a 1-in-32 chance — according to figures from NASA's Center for Near Earth Object Studies last week.

Donaldjohanson is not a Trojan asteroid, but is located in a convenient position for Lucy to swing by before continuing on to its main targets.

That was enough to trigger some concern, but astronomers cautioned that more data was needed to fully understand the asteroid's trajectory and size. The new data is in.

It was only a few days ago that a certain fear-mongering website named, ahem, Ars Technica published an article about the prospect of a killer asteroid striking the planet Earth in the year 2032. At the time, the odds of a small asteroid first discovered late last year—and designated 2024 YR4—hitting us were non-negligible. There was an estimated 3.2 percent chance that the large rock would impact the planet eight years from now. In the days since then, the odds have fallen dramatically. Based

The potentially hazardous asteroid 2024 YR4 caused consternation over the last few weeks as its odds of hitting Earth in 2032 dramatically rose. Now, those odds have plummeted to near-zero, as astronomers’ calculations of the asteroid’s path have been updated to indicate that Earth is almost certainly not in the space rock’s plans. Almost. According to NASA’s Center for Near-Earth Object Studies (CNEOS), the asteroid’s current chance of hitting the planet in 2032 is 0.28%, or a 1-in-360 shot. T

An asteroid discovered late last year is continuing to stir public interest as its odds of striking planet Earth less than eight years from now continue to increase. Two weeks ago, when Ars first wrote about the asteroid, designated 2024 YR4, NASA’s Center for Near Earth Object Studies estimated a 1.9 percent chance of an impact with Earth in 2032. NASA’s most recent estimate has the likelihood of a strike increasing to 3.2 percent. Now that’s not particularly high, but it’s also not zero. Ars

According to NASA's Jet Propulsion Lab, near-Earth asteroid 2024 YR4 now has a 3.1 percent chance of colliding with our planet on December 22, 2032. That makes it the highest-threat asteroid ever detected, as Euronews reports. As of late January, the probability was sitting at just 1.3 percent, which then rose to 2.1 percent last week before rising yet again.
