An asteroid could hit Earth in 2032. Don't panic — yet
Why it matters: The near-Earth asteroid, officially named "2024 YR4," could be a regional hazard if it actually hits the planet, NASA says.
Driving the news: The odds that YR4 will hit Earth have been creeping up over the past few days, and stand at 2.1% as of Feb. 12.
Those probably aren't numbers you'd play in Vegas, but it's still a 1-in-48 chance of impact.
Threat level: YR4 currently rates as a 3 on the 0-to-10 Torino scale, which measures asteroid collisions' potential hazards.
That translates into possible "localized damage" — which means you wouldn't want to be near the impact zone, but this isn't considered an existential Earth-wide threat.
Reality check: YR4 was only first reported to near-Earth asteroid watchers in late January, and it's possible that its impact odds will lessen as researchers spend more time observing and learning about it and its path through space.
What they're saying: "Even though it's a very, very low impact probability, it's not often that something this size even reaches that level," Kelly Fast, acting planetary defense officer at NASA's Planetary Defense Coordination Office, tells Axios.
"It's a chance to continue to bring the capabilities we have to bear to get the most information possible, to hopefully get enough information for the probability to drop to zero, to know well enough that it's going to pass the Earth safely — and if not, then to have that information also."
"But it's so early that, at 2%, it's at that level where, okay, planetary defenders of the world, keep an eye out. But otherwise, it's not something to lose sleep over."
What's next: NASA is planning to launch the Near-Earth Object Surveyor space telescope later this decade, which will look for potentially threatening objects using infrared sensors.
Those are better able to spot darkly-colored asteroids compared to visible light telescopes, Fast says.
And in 2022, NASA successfully tested asteroid-deflection technology that one day could truly save our bacon — no Bruce Willis or Ben Affleck required.

An Aurora Is Hitting Monday Night Only and Will Be Visible in Over a Dozen States
As the sun continues the tumultuous peak of its 11-year cycle, more instances of aurora borealis have been expected. The most recent instance was earlier in August when auroras lit up the skies in 18 states. It seems the Earth is in for another battering of solar material as another aurora has been forecast for Monday night, and it should be a pretty decent one for states in the northern US. According to NOAA, the Earth will experience a geomagnetic storm with a Kp 5 rating. For the uninitiated, the K-index is a measure of how strong geomagnetic storms are and a Kp 5 rating is designated as a "moderate" storm by NOAA. In general, the stronger the geomagnetic storm, the further south an aurora appears, and a Kp 5 will almost assuredly drag the northern lights into the US. This week's geomagnetic storm comes to us courtesy of the sun. Per SpaceWeatherLive, there were a number of solar flares ejected from the sun over the last several days, a pattern of increased solar activity that also caused the aurora on Aug. 8. Most of the states bordering Canada will see a light show. NOAA Where will the aurora be visible? The states that can be expected to see it include Washington, the northern tip of Idaho, Montana, North and South Dakota, Wisconsin, Minnesota and the northern horn of Michigan. If it's dark enough and people face north, it may also be visible in Wyoming, Iowa, New York, Vermont, New Hampshire and Maine. Of course, the best view will be in Alaska, where the whole state should be able to see the most intense part of the aurora. NOAA says the storm will peak at around 0300 to 0900 UTC, which translates to 11 p.m. through 5 a.m. ET (8 p.m. to 2 a.m. PT). Tips to see the aurora If you live in one of the aforementioned states, your best bet is to get somewhere elevated and away from city or suburban light pollution, and then simply point yourself north. Photographers looking to catch a glimpse will want to use long exposure times to give the camera ample time to take in as much aurora light as possible. If you plan on taking a trip out to the sticks to see it, keep an eye out for shooting stars at the tail end of Perseids meteor shower and you may be able to spot some plants in the last planet parade of 2025.

Mysterious Object Hurtling Toward Us From Beyond Solar System Appears to Be Emitting Its Own Light, Scientists Say
Last month, astronomers made an exciting discovery, observing an interstellar object — only the third ever observed — hurtling toward the center of the solar system. The object, dubbed 3I/ATLAS, has caught the attention of Harvard astronomer Avi Loeb, who has a long track record of making controversial predictions about previous interstellar objects being relics from an extraterrestrial civilization. While there's been a growing consensus among astronomers that the latest object is a comet, Loeb has continued to entertain the idea that it may have been sent to us by an intelligent species from outside of the solar system — and he's far from backing down. In a blog post over the weekend, Loeb pointed to observations by NASA's Hubble Space Telescope, which showed a "glow of light, likely from a coma, ahead of the motion of 3I/ATLAS towards the Sun." A coma is the hazy and luminous cloud that surrounds the nucleus of a comet. However, there's "no evidence for a bright cometary tail in the opposite direction," he wrote, with scientists suggesting it was evidence that dust was evaporating from the object's Sun-facing side. The observations led Loeb and his colleagues to an intriguing, albeit far-fetched possibility: is the mysterious space object generating "its own light?" After deliberations with his colleague and Harvard astrophysicist Eric Keto, Loeb suggested that the "simplest interpretation" of 3I/ATLAS' observed "steep brightness profile" is that its nucleus "produces most of the light." That would also mean that its actual size is much smaller than currently thought, roughly in line with the size of the first two interstellar objects we've observed, 'Oumuamua and 2I/Borisov. The Harvard astronomer suggested two possibilities: either 3I/ATLAS is naturally emitting radiation because its a "rare fragment from the core of a nearby supernova that is rich in radioactive material" — or it's a "spacecraft powered by nuclear energy, and the dust emitted from its frontal surface might be from dirt that accumulated on its surface during its interstellar travel." Loeb deemed the former explanation "highly unlikely," and the latter as requiring "better evidence to be viable." Loeb previously argued that the object's unusual trajectory — which includes suspiciously close flybys of both Earth and Jupiter — and its lack of a visible tail both undermine the theory that it's a comet. Intriguingly, 3I/ATLAS will come within spitting distance — at least in astronomical terms — of Mars this fall, giving us a tantalizing opportunity to have a first-hand look. Loeb suggested using NASA's Mars Reconnaissance Orbiter to point its scientific instruments at the rare visitor. Best of all, scientists at the space agency appear to be game. "This morning, I encouraged the HiRISE team to use their camera during the first week of October 2025 in order to gather new data on 3I/ATLAS," Loeb wrote. "They responded favorably."
