2 meteor showers peak on the same night this week ‪—‬ how to get the best views, despite a near-full moon

26 July 2026 at 13:00

Two meteor showers will peak together overnight on Thursday, July 30, into Friday, July 31 — but skywatchers should expect a moonlit challenge rather than a dazzling display.

Both the Southern Delta Aquariids and the Alpha Capricornids reach maximum activity just one night after July's full Buck Moon, which turns full on Wednesday, July 29. According to the American Meteor Society, the moon will still be 98% full during the peaks of those meteor showers, meaning bright moonlight will wash out many of the fainter "shooting stars."

This year, the Southern Delta Aquariids are active from July 12 to Aug. 23 and peak on the night of July 30-31. The meteor shower can result in about 25 shooting stars under ideal dark skies, but the full moon makes this year's timing far from perfect. The Alpha Capricornids, which are active from July 3 to Aug. 15 this year, offer around five meteors per hour on the same peak night. That's not many, but the Alpha Capricornid meteor shower is known for bright fireballs — space rocks that shine brightly, and sometimes colorfully, as they catch fire during the plunge through Earth’s atmosphere.

From North America, the moon will appear bright for much of the night around the meteor showers' peak. A nearly full moon does not stop meteors from occurring, but it brightens the sky enough to hide the faintest streaks. That's particularly important for the Southern Delta Aquariids, which can be faint and typically lack fireballs, according to the American Meteor Society. Even still, the overlapping showers make a great night for practicing your meteor shower photography or for taking pictures of the moon.

The best time to try watching will be between midnight and dawn, when the radiant — the point from which the meteors seem to emanate — of the Southern Delta Aquariids, the constellation Aquarius, is highest in the southern sky. Observers in the southern U.S., Mexico and the Caribbean will be better placed than those farther north because Aquarius climbs higher at lower latitudes.

For the best chance of seeing some shooting stars, keep the moon behind you or blocked by a building, tree or hill, and look toward the darkest part of the sky. Meteor showers are always best viewed with the naked eye.

If you're clouded out — or mooned out — during the July meteor peaks, don't worry, as you'll get a better opportunity in August. The Perseid meteor shower will peak overnight on Aug. 12-13, just after the Aug. 12 new moon, when skies will be moonless for the meteor shower's peak rate of 100 meteors per hour.

That same new moon will also cause a total solar eclipse to be visible along a narrow path through eastern Greenland, western Iceland and northern Spain. A partial solar eclipse will be seen from parts of Canada and the northeastern U.S. (Remember to protect your eyes with proper solar eclipse glasses at all times during the partial phases.)

The combination of a solar eclipse and the peak of a major meteor shower will make Aug. 12-13 potentially one of the most exciting days of the year for skywatchers.

'Fireball' meteorite that smashed into New Jersey home contains ingredients of life from an ancient proto-planet, study finds

18 July 2026 at 13:00

Scientists have discovered the building blocks of life inside a meteorite that smashed through a New Jersey home two years ago. The space rock contains amino acids, carbon compounds and other "prebiotic" molecules similar to what may have helped kick-start life on our planet, a new study shows.

Scientists on the study team — led by Peter Jenniskens, a meteor astronomer with affiliations at the SETI Institute and NASA's Ames Research Center — praised the homeowner in Hillsborough, N.J., for quickly preserving the meteorite after it fell through the roof on July 16, 2024, despite the adverse circumstances. His actions included using disposable gloves and aluminum foil to place pieces of the meteorite fragments into glass jars.

"I was at home at the time, heard a loud crash and found a hole in the ceiling of the master bedroom," the homeowner, who was not named, said in a statement from the SETI Institute. "I smelled a strong, sulfur-like odor and saw many black fragments, along with debris and black dust that covered my bed, carpet and surrounding areas."

Those meteorite pieces were precious, the scientists said, and likely came from an ancient solar system planet that wasn't fully formed. "A forensic study of the fragments revealed that they contained preserved bits from near the surface of a small primitive asteroid where it experienced concentrated salty fluids — a process not previously known from this type of protoplanet world," Jenniskens said in the statement.

The study, published July 15 in the journal Science Advances, also traced how the meteorite got to the house. Earlier on July 16, 2024, at least 60 observers in New York, New Jersey and other Northeastern states spotted a meteor later confirmed to be traveling at 32,000 mph (51,500 km/h). At least 16 people in New York and New Jersey reported feeling the meteor's shock wave.

The rock broke apart in midair, with observer reports stopping when the meteor reached 22 miles (35 kilometers) in altitude, although Newark Liberty International Airport briefly tracked pebbles falling from the sky with Doppler weather radar after that. Fragments from only one meteorite ‪—‬ called Hillsborough, after the town where it crashed through the New Jersey home ‪—‬ were recovered.

The American Meteor Society used its cameras in Northford, Connecticut, and Douglassville, Pennsylvania — along with a doorbell camera in Wayne, New Jersey — to figure out the meteor's origin, Mike Hankey, an operations manager at the American Meteor Society and co-author of the study, said in the statement. "The path traced back to low in the asteroid belt."

Hillsborough is the second stony meteorite of its type ever spotted in a fall. Later analysis showed that the meteorite is full of ancient brines or salt. Scientists classified the meteorite as a type of stony space rock called a carbonaceous chondrite.

Scientists will compare the salt minerals to samples of asteroids Ryugu and Bennu, both of which contain ingredients of life and are samples of another carbonaceous chondrite type that formed earlier than Hillsborough. This analysis could help scientists further trace the origins of life-friendly chemistry in the early solar system.

We Have Visitors: Interstellar Material from Nearby Debris Disks

6 February 2026 at 17:00

'Oumuamua

Traversing the galaxy from places yet known, a few interstellar objects have taken a quick dip into our solar system. These objects have inspired a frenzy of questions regarding their origins and paths that led them here. A recent study took to nearby planet-forming stellar systems as possible launching posts.

Interstellar Object Origins

As 3I/ATLAS was first spotted entering the solar system in July 2025, all eyes turned to the curious interstellar visitor. Just the third interstellar object astronomers have observed, 3I/ATLAS joins 1I/ʻOumuamua (2017) and 2I/Borisov (2019) in capturing our attention and igniting many questions regarding their origins and journeys to our corner of the Milky Way. While astronomers have characterized these objects’ compositions, sizes, and paths through the solar system, the mechanisms by which these objects leave their origin systems and travel the galaxy before arriving here are not well constrained. 

These three large bodies are just part of the interstellar material visiting the solar system — spacecraft have detected an influx of small interstellar dust particles, and while not yet directly confirmed, interstellar meteoroids burning up in Earth’s atmosphere are possible. This loose material likely originates in dusty, planet-forming disks (debris disks) around stars — rubble kicked out into interstellar space, sending chemicals, organic compounds, and perhaps even the precursors of life to other nearby systems. Understanding the origins and trajectories of such material will allow us to investigate planet formation and how developing systems may impact their environments.

Deliveries from Debris Disks

Debris disks offer ideal testbeds for tracing small bodies and dusty material through the galaxy. Interactions with large planets in debris disks can launch loose material like planetesimals and dust into interstellar space. To explore how debris disks may drive interstellar visitors to our solar system, Cole R. Gregg and Paul A. Wiegert (The University of Western Ontario) simulated how much material the 20 nearest debris disks would contribute to the interstellar object population of our solar system.

The authors modeled the trajectories of ejected material from each debris disk within a simulated Milky Way, running the simulations backward and forward in time to trace the ejecta over 100 million years. These simulations show that material from each of the 20 systems is currently expected to be within our solar system. For interstellar objects (≥100 meters), the simulations predict that about two objects from these debris disks are currently within the inner solar system.

Trickier to spot, smaller meteoroids (≥200 microns) that would appear as meteors in Earth’s atmosphere are also expected. The only way to observationally confirm interstellar origins for meteors is based on how fast they are moving relative to the material in our solar system, or their excess velocities. Based on the simulations, many of these smaller particles have low excess velocities, making them observationally difficult to distinguish from bound solar system objects.

Observational Connections and Expectations

How do these simulations compare to observations? From their analysis, the authors identified where the interstellar material from each debris disk would first enter the solar system. Comparing these to the entry locations of 1I/ʻOumuamua, 2I/Borisov, and 3I/ATLAS, ʻOumuamua appears near the entry locations for debris from HD 166 and HD 38858. (2I/Borisov and 3I/ATLAS had no such match up in this sample of debris disks.) However, tracing ʻOumuamua’s travel backward, its closest approaches to these systems are about 32 and 18 light-years away, respectively — likely too far to have originated from either system but still a clear proof of concept that we can place interstellar objects near potential systems of origin. 

Where are the expected interstellar meteoroids? Current meteor detectors including the Canadian Meteor Orbit Radar (CMOR) and the Global Meteor Network (GMN) search the sky for incoming material. While the simulations predict hundreds of meteoroid-sized particles from each debris disk currently in the inner solar system, the small collecting area of CMOR and the limiting size of grains detectable by GMN statistically require decades of observations to detect even a single interstellar meteoroid. Thus, the lack of detections thus far is not surprising, but with advanced instrumentation, discoveries of more interstellar particles and objects are imminent.
